Corporate Toolkit MTWatch MTValidate MTEnergy MTCollect

Corporate Toolkit The Micro Thermo Corporate Toolkit is a series of web-delivered data collection, reporting and validation tools that allow facility managers to see and manage the refrigeration-related activity at their stores To collect and manage that data in order to make better decisions on managing refrigeration. These decisions ultimately result in better food quality and higher levels of energy savings.

Data Reporting - MTWatch
MTWatch is a web-based reporting tool. It generates a variety of pre-defined reports that provide details about refrigeration related activity at all your stores

Pre-defined reports provide quick access to key data. Reports include: alarm limits, bypasses and overrides, calibration changes, emergency defrosts and more

User-defined reports are created by you, and can contain data from all parts of the system. These reports can be used for more in-depth problem analysis

Pre-defined report – Alarm Limits – Select that report and the dates of interest

Selecting “report full details” provides specific descriptions of what changed, who changed it and more

System Control - MTValidate
MTValidate allows users to set up automatic reports to verify or validate that key set points are within acceptable ranges

Accountability - MTEnergy
MT’s Energy reports are supermarket focused tools to ensure your energy management program is optimized by providing integrated load shedding, real time pricing, and prioritization across your supermarket chain

Corporate Toolkit - MTCollect
MTCollect allows users to select what data they want to see (temps, pressures, etc) and automatically “collects” that data from stores

HW & SW FAQ Q: How many boards can be installed in each site?
A: Far more than you will ever need ,252 boards (124 x 124 – 124) Q: How long can the wiring be in each site? A: Far more than you would ever need miles (3000 ft * 3000 ft = 375,000 ft ) Q: How many points can be monitored in each site? A: Enough for the biggest supermarket.... up to 3000 (advertised value, technical value is 4096 and possibly more) Q: What is the maximum bandwidth? A: The cabling technology allows 78 kbps on each channel and optionally 1.25 Mbps on the backbone. (200 points talking in the same second is the maximum actual traffic. So 3000 points can talk every 15 secs) Q: What is a typical refresh rate for a given point? A: Points are refreshed on the user interface every 3 secs, but only if they have changed.

HW & SW FAQ Q: What hardware does the MT Alliance run on?
A: An industrial grade data logger. The box as no openings so it won’t get dirty. The box itself acts as the heat sink. It contains no moving parts. It is fanless and uses solid state drive technology so it can work when mounted directly on a rack. Q: What operating system does the MT Alliance run on? A: Windows Embedded is the preferred choice. It also runs on Windows XP Pro and Windows 7. Q: Is there a backdoor to get into the system? A: There is no fixed or pre-defined password. Q: How many users can be defined? A: There is no preset limit on the number of user accounts that can be created. Q: How many views can be defined? A: At least 50 and at most 344 (1+49*7). Q: How many racks can be installed? A: Up to 49 Racks can be installed.

HW & SW FAQ Q: How much historical data can be kept at each site?
A: 3000 points can be stored every minute. For up to 5 years. (7.9 billion point values) Q: What database is used? A: The relational database is Paradox (or Borland database engine) Q: Can we read from that database? A: An ODBC driver could query the configuration data (ex: Fresh Management). However historical data is password protected. The recommended approach is to invoke MT Alliance Web Services. Q: Can we write to that database? A: No, writing to the database directly is not supported. The historical data can’t be changed. Some configuration items can be changed via the EFM Workstation or via Web Services.

HW & SW FAQ Q: How many condensers per rack are supported? A: 1.
Q: How many suction groups per rack? A: Up to 3. Q: How many compressors per suction group? A: Up to 10. Q: How many circuits per rack? A: Up to 40. More than 40 is possible by declaring a virtual rack. Q: In a retrofit application, can I reuse existing CPC sensors? A: Yes, absolutely. The Alliance can also coexist with CPC and share the CPC sensors by using differential input boards (using Alliance as a food safety alarm system)

HW & SW FAQ Q: Are MT Alliance Web Services open?
A: Micro Thermo will support anyone who wishes to write their own applications based on web services. (ex: HEB for global account management, SensusMI For HVAC predictive maintenance, CanMet for refrigeration energy analysis) Q: What can we do using Web Services? A: Manage user accounts, pull out historical data for any point, any period. Pull out changes made by users, active alarms, old alarms, and alarm limits for any point, any period.

Suction Pressure Control
Our Position Utilizes the advantages of floating pressure when temperature is met – so less compressor run time = lower energy use. How Do We Do It? Select the coldest circuit as your reference, and then provide some basic parameters to set high and low limits for pressures and temperatures and the system is ready to go. Where Is The Value? The end result is compressors are run the least amount necessary to maintain required temperatures. This means less compressor wear AND less energy usage. $3,719 in annual savings By using a proprietary control algorithm, the Micro Thermo compressor control can identify non-functioning compressors – and then remove the compressor from the control scheme. This means that the compressor rack is always running at it’s optimum. By not continuing to cycle non-functioning compressors, additional wear to the compressor is reduced, and overall cycle time of the rack is reduced – which has a direct impact on electricity usage and ultimately costs See The Calculations

A combination of compressor and EEPR management provides unmatched balancing of compressor cycling based on a more stable case. How Do We Do It? By combining the control of compressors and EEPR to provide more stable case temperatures. Where Is The Value? The end is stable operating temperatures and reduced energy usage by a number of system components. $4,300 in annual savings Our Position The Micro Thermo circuit control is a unique combination of compressor and EEPR management. This combination provides unmatched balancing of compressor cycling based on a more stable case temperature via proper use and management of a DT-EEPR. How Do We Do It ? By combining the control of compressors and EEPR, the Micro Thermo system can utilize the capabilities of both to provide more stable case temperatures. Doing this provides a number of important benefits. Beyond better overall food quality, stable temperatures means the system can allow certain control parameters to “float” allowing for more flexible control which can result in less use of energy consuming components in the refrigeration system – namely compressors.

Lighting Control Our Position How Do We Do It? Where Is the Value?
The ability to accurately control lighting is essential in an overall energy management system. How Do We Do It? Micro Thermo makes controlling lighting simple with intuitive “plug ins” that seamlessly integrate with the rest of the system. Where Is the Value? By properly configuring AND using lighting control in the overall energy management system electricity usage related to lighting can be reduced up to 5% annually $3,000 in savings The energy savings assessments – Typical Supermarket of 46,000 sq. ft., total energy consumption 52.5 KWH per sq. ft. per year; $0.11/KWH: $265,650 in electricity per year. Lighting represents an annual expense of $66,400. It is reasonable to say that MT control system, by its ease to configure, its facility to review historical data and its unique possibility to alarm excessive by-pass use of lighting schedule, that MT lighting control can save 5% in lighting electricity use, which represents energy savings of a value $3,000 per year. Maintenance For parking light control, the astro-clock is replacing the outside photocell. The astro-clock comes with the lighting control application at no extra cost. Therefore, there is a direct saving on the initial cost of the photocell and its replacement when it will cease to function properly (5yrs life expectancy). If we say that it takes a service call to replace the photocell (4hrs at $85/hr), the net savings are: Initial photocell: $200 Annual Maintenance: $108/yr Our Position Lighting is second only to refrigeration for energy costs in the typical supermarket. So the ability to accurately control lighting is essential in an overall energy management system. How Do We Do It ? We believe that for an energy management system to work, it has to be used – and that includes all the various components. Micro Thermo makes controlling lighting simple with intuitive “plug ins” that seamlessly integrate with the rest of the system Where Is the Value By properly configuring AND using lighting control in the overall energy management system, it is estimated that electricity usage related to lighting can be reduced up to 5% annually – which for a typical sized store can be up to $3000 See The Calculations

HVAC Control Control a wide variety of RTU’s, AHU’s, DPU’s, Make-up air, VAV’s and Custom applications. Humidity or dew point control Built-in Load shed functions Heat Reclaim Reheat Space Heat Hot water Monitored to prove application

HVAC Control – Ambient Our Position How Do We Do It?
Any comprehensive energy management strategy must include controlling temperature and absolute humidity. How Do We Do It? Controlling store humidity by controlling dew point temperature. Where Is The Value? Reducing absolute humidity by 45% from the case manufacturer standards has shown that at energy usage for supermarkets’ refrigeration racks, anti-sweat and electric defrost was reduced between 4% and 29% $1,100 in savings In the past 20 years, several studies have shown the effect of indoor space conditions (Tº and %RH) on refrigeration energy usage. Between the store temperature and the relative humidity, the store temperature is probably the ambient condition which is the easiest to control. However, the relative humidity is more underhand. Even if Refrigerated case manufacturers are rating equipment design capacities based on store ambient temperature and relative humidity (75ºF DB and 55%RH), the dew point temperature or the absolute humidity (grains H2O/lb air) are the correct representation of the relationship between store humidity and case energy performance. Laboratory tests and field experiments have proven that energy savings are directly related to reduction of absolute humidity. When reducing absolute humidity by 45% from the case manufacturer standards, it was observed that energy usage for supermarkets’ refrigeration racks was reduced by 4% to 29% for Low Tº and Med Tº; energy usage for anti-sweat heaters was reduced by 25% and energy usage for electric defrosts reduced by 22%. The energy savings assessments – Typical Supermarket of 46,000 sq. ft., total energy consumption 52.5 KWH per sq. ft. per year; $0.11/KWH; 50% of the total is for refrigeration (30% for refrigeration racks), anti-sweat heaters – 75,000 kw-hrs (using anti sweat control) and electric defrost – 100,000 kw-hres/yr. By controlling properly the store absolute humidity by a better dew point control, it’s reasonable to assume that we will obtain a minimum of 20% of these savings. Based on these assumptions, the energy savings are: Refrigeration racks: $2,630/yr Anti-Sweat heaters: $425/yr Electric Defrosts: $500/yr Total annual energy cost reduction of $3,555. HVAC Our Position Proper control of ambient conditions within the store are critical. Studies and laboratory tests have shown that energy related to defrosting and anti-sweating are Directly related to the control of temperature and relative humidity in the store. Any comprehensive energy management strategy must include controlling these ambient conditions How Do We Do It ? By controlling humidity as well as temperature – as a part of the overall energy management process. Where Is The Value Quantitative “before and after” studies with the Micro Thermo store ambient control in place have shown energy savings up to 29% for the refrigeration racks, up to 22% savings on anti-sweat heaters and up to 25% savings on defrost heaters See The Calculations

HVAC Control –Heat Reclaim
Our Position Heat reclaim (especially in Northern climates) is a necessary component of an effective energy management system. How Do We Do It? Integrating heat reclaim into the overall energy management process AND monitoring it. Where Is The Value? Using heat reclaim to supplement/replace electric or gas heating for hot water or space can help reduce the risk of an extra $10,000/yr spent for space heat by not using heat reclaim. $10,000 reduced risk Industry estimates reveal that the average supermarket uses 400 – 1200 gallons per day of Hot Water for cleaning, hand washing, sanitation, & food preparation. If the supermarket relies on electric element back-up for hot water production in lieu of heat reclaim; the annual cost of providing 800 gallons of hot water/day is as follows: .012/kWh = $ /kwh = $ $10,556 If the supermarket relies on a natural gas appliance for space heating in lieu of heat reclaim; the annual cost of providing 300,000buth input/270,000btuh output space heating for 8000 heating hours/season is as follows: $3.77/MMbtuh = $ $3.96/M Therefore a disabled or inactive heat reclaiMbtuh = $9504m system causes a direct increase of energy costs to provide either hot water production or heated air for space heating. THE EXPECTATION IS THAT MOST STORES WILL ONLY DO ONE OR THE OTHER SO REALISTIC SAVINGS ARE ~ $10k/yr Heat Reclaim Our Position Interviews and analysis have shown that heat reclaim systems are often disabled due to faulty HR valve. Micro Thermo believes that in North Climate HR is a necessary component for Supermarkets and we are making sure that it works properly. How Do We Do It ? By integrating HR, and making it part of the monitoring and alarming process, Micro Thermo takes full advantage of the excess heat produced by the refrigeration to heat the store. Where Is The Value By monitoring the performance of HR system, Micro Thermo is making sure that space heating and hot water heating can be accomplished without extra electric or gas heaters. A conservative estimate puts annual savings for both in a typical store at nearly $20,000/yr. See The Calculations

Energy Control Our Position With energy costs increasing at an average rate of 2%-3% annually – controlling energy usage in refrigeration is critical to saving money on operating costs. How Do We Do It? By fully integrating HVAC, lighting and refrigeration control into the core Micro Thermo system. Where Is The Value? The Micro Thermo system provides advanced load shedding control out of the box. For the last 10 years, electricity cost has increased at a 2.5% annual rate, which is higher than the annual inflation rate at 1.99%. In 2011, a supermarket is spending $55,000 more in electricity than he was spending 10 years ago. Controlling the energy usage of a supermarket represents today an opportunity that supermarket operators cannot ignore anymore. Micro Thermo is offering an integrated solution for load management that is unmatched by the competition. MT system can do load shedding command by de-activating physical contactors and/or by sending load shedding command to systems controlled by MT using the network. By using the MT network and the load shedding configuration tool present in all systems application (HVAC, lighting and refrigeration), MT system is offering endless possibilities of load shedding combinations. Load shedding can be achieved for peak shaving, real time pricing application, corporate demand response programs and for generator mode when a generator is present on site but with limited capacity. The energy savings assessments – Typical Supermarket of 46,000 sq. ft., total energy consumption 52.5 KWH per sq. ft. per year; $0.11/KWH: $265,650 in electricity per year with a KW demand of 400KW. KW demand can represent up to 50% of the total electricity cost. By controlling properly the demand reduction by only 10% (400KW to 360KW), this will represent more than $13,000/yr in reduction for the electricity annual cost. Our Position With energy costs increasing at an average rate of 2%-3% annually, and with HVAC, lighting and refrigeration costs making up well over half of a supermarket’s energy consumption – controlling energy usage in those areas is critical to saving money on operating costs. To do this efficiently and with value, these systems need to work together to shift and shed electrical loads in order to take advantage of the best prices for power, and the best opportunities to reduce overall energy consumption. How Do We Do It ? By fully integrating HVAC, lighting and refrigeration control into the core Micro Thermo system, we provide optimized, real time load shedding, peak shaving and other energy cost saving techniques in an almost endless array of combinations. Where Is The Value With no extra software or controllers required, the Micro Thermo system provides advanced load shedding control out of the box. By integrating HVAC, lighting and refrigeration control in one system, we are unmatched in our ability to shift and adjust energy loads across all those systems to maximize savings. $8,000 annual savings/store* See The Calculations * over systems with no load shaving

$36,809 savings/year over mechanical control
It All Adds Up Micro Thermo Technologies can enable savings of between 8% and 28% per year on refrigeration energy costs Based on a typical supermarket… 46,000 square ft. 52.5 KWH/square ft. – year $0.11 /KWH $265,650 total $132,825 refrigeration energy (50%) Dail – notes 11/21/11 – above slide was on the low end of estimate range – can correct store size, cost per KWH or, KWH/sqft-yr This is a general energy statement of how much we save above and beyond any competitors system – for just refrigeration component Typical store energy spend ranges between $270K and $320K – so refrigeration energy ranges between $135K and 1$60K For MVC – we claim 8% greater savings than any other competitor’s EEV case control – savings in range of $10.8K to $12.8K All other benefits (w/o MVC) run about 12% savings on average – which is between $16.2K and 19.2K Grand total energy savings (20%) would range from $27K to $32K We need to make sure the sum of the refrigeration energy components add up to the total stated here. I know the MVC appears to be extremely low to estimate discussed during last call (clarify and adjust as needed). $36,809 savings/year over mechanical control $10,000 over competition

Service Call Reductions
Our Position By weeding out nuisance alarms while elevating quickly real alarms, service can be performed before food is at risk. How Do We Do It? By intelligently monitoring how the system performs over time, which alarms seem to be cumulative (ie: issues that can result from the same alarm condition happening repeatedly), and making it easy to identify alarms which means you can resolve them more quickly. $4,725 Savings Per Year Our Position Service costs can add up quickly for a supermarket. But legitimate service needs can’t be ignored or food quality and safety (and ultimately shrink) is at risk. But how can Micro Thermo help reduce service costs ? By carefully weeding out nuisance alarms while elevating quickly real alarms so that service can be performed before food is at risk How Do We Do It ? Micro Thermo reduces refrigeration-related service costs by minimizing/eliminating nuisance alarms and making alarm identification and resolution fast and easy. We do this by intelligently monitoring how the system performs over time, which alarms seem to be cumulative (ie: issues that can result from the same alarm condition happening repeatedly), and making it easy to identify alarms which means you can resolve them more quickly. All of that adds up to lower service costs for the refrigeration systems. See The Calculations

This reduction equated to a $4,750 annual savings.
Service Call Reduction Service Call Reduction Recent studies by Micro Thermo with actual customers have shown a dramatic decrease in the overall number of legitimate alarms requiring service. By analyzing alarms and identifying those which are merely nuisance alarms – at the monitoring station – reduces the number of actual service calls required. Average time to attend an alarm 5 Minutes People involved 1 Fee/Hour $ 15.00 USD/hour Total Cost per alarm $ 1.25 USD No. Alarm Before 350 Alarms No. Alarm After MT 35 Difference 315 Monthly Savings $ 93.75 Annual Savings $ 4,725.00 Actual MT customer who saw a 90% reduction in service related alarms after installing the MT system. This reduction equated to a $4,750 annual savings.

Alarm Prioritization Our Position How Do We Do It? Where Is The Value?
It takes more time to identify and acknowledge an alarm when all alarms are triggering the same priority – so the ability to control service costs will suffer. How Do We Do It? 1) we make it easy and quick to identify and acknowledge and alarm and 2) we provide a flexible system to automatically prioritize alarms. Where Is The Value? Acknowledgment is all part of the same 1-click screen and users can assign a priority value to any of the various alarm types or categories. For the alarm prioritization, MT is working on 4 levels of alarm: High, Medium, Low and Notice. These levels are all configurable. You can send alarm to a central, to a pager or by . Level High will be used normally when you want to react immediately to the alarm. Medium will normally be used when you want to react in the next 2 hours. Low will be used when it is not important and that it can wait until tomorrow. Notice is normally a local alarm only. These four levels, used properly, can help to better manage service calls. Our Position A key component in reducing service costs is being able to quickly assess an alarm and then provide automatic ways to assign a priority to that alarm. It it takes more time to identify and acknowledge and alarm or if all alarms are triggering the same priority – the ability to control service costs will suffer. How Do We Do It ? Micro Thermo provides value in two ways: 1) we make it easy and quick to identify and acknowledge and alarm and 2) we provide a flexible system to automatically prioritize alarms. Where Is The Value ? Micro Thermo provides value by making the alarm assessment and acknowledgment all part of the same 1-click screen, and by allowing users to assign a priority value (4 different priorities from “High” (urgent) to “Notice” (take note of it, but no immediate action) to any of the various alarm types or categories.

Alarm Prioritization – Example
Total time involved with other system per store 92 minutes Total time involved with MT per store 26 Time difference 66 Ave hourly wage $15.00 USD/hour Hours saved per store 1 hour Store interrogated per year (average) 450 Stores Total savings $6,750.00 USD Savings: minutes per alarm acknowledgment 10 minutes walk to the mechanical room Number of alarms per year: 2 alarms/day * 365 days = 730 alarms/yr Yearly Savings: 730 alarms * 12/60 hr/alarm * 85$/hr = $12,410/yr (gain in productivity) See The Calculations

Service Costs - Diagnosis
Our Position Diagnosis needs to include being able to prevent problems, and ultimately predict potential problems and take action before they even occur. How Do We Do It? By being able to track and analyze cumulative alarms (alarm details over time) we can actually bring predictive and prognostic service to users today, in addition to standard preventative maintenance. The Cumulative Alarm Control System from MT, used on refrigerated cases, will permit to identify potential maintenance problems before they occur. By identifying these potential problem in advance, it is now possible to plan corrective actions during normal operation hours, thus eliminating potential repairs done at night in over time. The maintenance cost savings assessments – Typical Supermarket of 46,000 sq. ft. will have 100 refrigerated cases. Assuming that 15% of the cases will need repairs during a year, for a store that has 12/12 operating hours, 7 days a week, the probability that a case will break down during over time period is 108/168. Cases break down during week days at night (time and a half): 6 Cases break down during week-ends (double time): 4 Annual savings by planning repairs during working hours at 85$/hr – 4hrs/case: $2,380/yr Our Position Identifying problems is a key component to any robust service strategy. Being able to identify what caused the problem (root cause) is critical component for day-to-day service management. But that’s not enough. Diagnosis now needs to include being able to prevent problems, and ultimately predict potential problems and take action before they even occur. How Do We Do It ? Micro Thermo’s advanced management and analysis of alarms is both unique to our system, and is designed to provide fast and relavent information to users. By being able to track and analyze cumulative alarms (alarm details over time) we can actually bring predictive or prognostic service to users today. Where Is The Value ? By being able to track and monitor alarms as they accumulate over time, we can help users set up actionable preventative maintainence programs, the Micro Thermo system provides a direct path to savings on actual maintainance costs

Service Costs - Diagnosis
Where Is The Value? Micro Thermo allows users set up actionable preventative maintenance programs which provides a direct path to savings on actual maintenance costs. By being able to plan for preventative – and even predictive – maintenance to be done during work hours, instead of after-hours emergencies, customers can save nearly $2400 a year in overtime pay differentials. $2,380 in annual savings See The Calculations

Add It All Up… Save Energy, Reduce Food Shrinkage, and Reduce Service Costs ENERGY SAVINGS $10,000 Save 8% versus competitive solutions (~ 28% vs. mechanical solutions) SERVICE SAVINGS $11,500 Save over 14% versus competitive solutions (up to 20% versus mechanical) FOOD LOSS SAVINGS $8,000 Save 8% versus competitive solutions (up to 10% versus mechanical) START UP SAVINGS $3,500 Save 10% on start up costs versus competitive solutions up to $33,000 in average total annual savings over competitive systems

Savings Calculations

And Now The Math Energy : 8% to 28% Annual Savings
Energy usage basis: $132,825 annually per store (slide #47) Refrigeration energy savings Suction pressure control – Assuming a 4 rack setup, each with varying evaporative loads Suction temperature is allowed to rise up to 5º Assume this 5º rise can be used 40% of the time annually Annual savings: 33,810 kWh saved due to reduced compressor run $0.11 USD/kWh = $3719 USD/year BACK

Refrigeration energy savings Compressor Control – 2 Racks / 6 compressors per Rack / $3,000 per compressor. Usual Compressor Life expectancy – 15 yrs. Added years on usual life expectancy by having auto tuned PID cycling for faulty compressor – 3 years. Annual savings on compressor replacement by using auto tuned PID cycling for faulty compressor - $400/yr. BACK

Refrigeration energy savings Condenser control – Enhanced floating condenser head pressure control has been shown in current installations to improve Rack’s performance by 10% during heating season (Ref – 4,575 Heating Degree-Days at 65ºF). For a typical size supermarket (~ 46ksqft), this 10% increase in rack performance during heating season equates to an annual savings of $7,970 BACK

Refrigeration energy savings Subcool Control – Using a 90HP R404A rack as a reference and subcooling liquid to 40º Up to 27,200 kWh saved annually At $0.11/kWh, savings can be as much as $3,000 annually BACK

Refrigeration energy savings Circuit Control – Based on our original estimate of refrigeration energy usage $ (#1) of $132,825 per store/per year Estimate that 2% savings gained from optimized valve profile control and 1.25% savings on overshoot control This comes to approximately $4,300 in savings annually BACK

Refrigeration energy savings EEV Case Control– Again using $132,825 as our refrigeration energy usage basis for a typical store Micro Thermo control of EEVs using highly accurate valve profiles can save approximately 8% or $10,626 per store / per year Since Micro Thermo EEV control is more reliable, approximately one service call per valve over a 5 yr period – so $40/year annualized. Assuming ~ 83 valves for typical store = $3,320 in savings BACK

Refrigeration energy savings Lighting Energy Savings Typical Supermarket energy consumption 52.5 KWH per sq. ft. per year; $0.11/KWH: $265,650 in electricity per year. Lighting represents an annual expense of $66,400. Due to it’s easy set up and full integration, MT lighting control can save 5% in lighting electricity use, which represents energy savings of $3,000 per year. BACK

8. HVAC energy savings Absolute Humidity Control– Dew Point Control: by properly controlling absolute humidity MT systems have shown an ability to lower energy used by refrigeration, anti- sweat heaters and defrost heaters. Past experience has demonstrated between 1% and 2% savings which on average will = $1,100 savings per year for a typical supermarket. BACK

And Now The Math Energy : 8% to 28% Annual Savings HVAC energy savings
Heat Reclaim– Typical Supermarket uses between 400 and 1200 gallons of hot water a day for cleaning, sanitation and food prep gallon is the average. Using electric heat, the cost will be between $7900 and $10,500 per year depending on the electric rate ( $0.11/kWh to $0.15/kwh). The typical supermarket experiences about 8000 heating hours per season. At an average cost for natural gas of $3.77/MBTUH, that is over $9000 per year So the potential lost savings of not using reclaimed heat, is on average close to $10,000 per year BACK

And Now The Math Energy : 8% to 28% Annual Savings – Summary
Total Refrigeration-related savings If you add up all our calculations: $3,719 $400 $7,970 $3,000 $4,300 $3,320 $1,100 $10,000 $36,809 This is a typical annual savings over mechanical solutions ~ 28%. Versus competitive enterprise solutions we estimate saving of ~ 8% which equals nearly $10,000 annually.

And Now The Math Food Loss : 3% to 10% Annual Savings
1. Stable Temperature Control Accurate Control of EEVs– By having more accurate valve control by using profiled EEVs, the Micro Thermo Alliance system can typically save 2% of the annual cost of controllable food loss. At $313,440 per year / per store, that equates to an annual savings of $6,269 BACK

And Now The Math Food Loss : 3% to 10% Annual Savings
Intelligent Alarming– Alarm Management By having highly intelligent alarm management – including cumulative alarms, and automatic alarm prioritization, we believe we can save up to another 8% on potential food loss costs per year. This equates to $25,000 per year BACK

And Now The Math Food Loss : 3% to 10% Annual Savings – summary
Total Food Loss Savings Adding up the potential savings: $6,259 $25,000 $31,259 This is the typical annual savings over mechanical solutions ~10%. Versus competitive enterprise solutions we conservatively estimate saving ~ 3% which equals nearly $8,000 annually.

And Now The Math Service : Up to 20% Annual Savings
Typical annual service costs are $15k - $30k Service Call Reductions Recent studies have shown that the Micro Thermo system will over time reduce alarms requiring service by nearly 90%. At a typical average cost of $1.25/alarm to service, and a typical store experiencing 350 alarms/year Potential savings is $4,725 per year BACK

Typical annual service costs are $15k - $30k Alarm Prioritizing By efficiently prioritizing alarms so that store personnel are addressing only the most critical alarms, Micro Thermo can reduce lost productivity which translates into savings Micro Thermo studies have shown that the Micro Thermo system can save nearly 1 hour / year in alarm prioritizing. At an average of $15/hr in wages and 450 stores being managed, that equates to an annual savings of $6,750 Back

Typical commissioning costs are $10k - $25k per store Simplified Setup Setup is also made significantly easier. Superheat setup and tuning time is greatly reduced as the Micro Thermo EEV case controller is essentially “self setting”. Assuming we save 30min from a standard mechanical setup (since we do have to setup the $85/hr = $3500 in one time setup costs BACK

And Now The Math Service : Up to 20% Annual Savings - summary
Typical Service and Setup Savings Adding up the savings: $4,725 $6,750 $3,500 $14,975 This is a typical annual savings over mechanical solutions ~ 20%. Versus competitive enterprise solutions we conservatively estimate saving ~ 14% which equals nearly $11,500 annually.
