Technology to Unlock your Engine’s Reserve Capacity Evans Cooling Systems, Inc.

2 Primary Benefits of Evans Waterless HD Thermal Coolant
Improves Fuel Economy Reduces Maintenance Costs Environmentally Friendly

3 How Fuel Savings are Acheived
Evans Waterless HD Thermal Coolant Allows Two Fuel Saving Techniques for Heavy Duty Engines*: Reduce fan-on time by raising fan-on temp to 230o F Increase the thermostat temperature to 215o F The fans for heavy duty diesel engines draw considerable horsepower. Minimizing fan operation leads directly to significant fuel savings. * See Two Fuel Saving Techniques for Heavy Duty Engines, Tom Light, May 16, 2009

4 Demonstrated Fuel Savings
Retrofitting a Mack MR688S (from the solid waste industry) with Evans coolant, with raising the fan-on temperature to 230o F, and increasing the fan off temp, showed an overall improvement of over 7%! SAE Type II test at PAVE Research Institute, using Evans Waterless HDTC with 215oF thermostats, proved a fuel economy improvement in excess of 3%!

5 SAE Type II Test Proves 3.04% Improvement in Fuel Economy!
Test was conducted Jan by the PAVE Institute at Auburn Univ. Evans Waterless Coolant and 215oF thermostats were used. Radiator fans were locked “on” to remove the fans as variables. Full report is available.

6 Example of Typical Savings for a Fleet of 300 Trucks
For fleets averaging: 5.5 mpg $2.25 per gallon 100,000 miles annually A typical conversion cost of $600-$800 per truck pays for itself in months! Annual fuel cost is $40,909 per truck. A 3% improvement in fuel economy yields an annual savings of $1,227 per truck, or $368,181 for the entire fleet! A 5% improvement in fuel economy yields an annual savings of $2,045 per truck, or $613,635 for the entire fleet!

8 Reduces Maintenance Costs
Waterless formula avoids corrosion and electrolysis. The absence of vapor forms a lower pressure system. Reduces stress on cooling system hoses reduces likelihood of leaks; any leakage is not a high pressure spray phenomenon. HDTC is a lifetime coolant; replacement cost is eliminated! Evans HDTC contains additives that remain stable and in suspension during storage and use, eliminating the need for replacement. Lengthens engine life by preventing pump and cylinder liner cavitation. Cavitation test showed significant reduction of cylinder liner cavitation.

9 Evans Waterless HDTC performed best in the “John Deere Engine Cavitation Test”
The John Deere Engine Cavitation Test, a 250 hour dynamometer test, is highly predictive of real-world cavitation erosion of cylinder liners. It is expected to be approved by the ASTM as the definitive test method. The test procedure was performed in April 2009 by a third-party laboratory using Evans HDTC. The results were so good that no water-based formulations, even ELC formulations, regardless of additives, come close.

10 Durability implications of using HDTC
Endurance of the engine is improved by maintaining control of engine metal temperatures at all times. The absence of cavitation erosion extends the life of cylinder liners and coolant pumps. No abrasive additive deposits. Pump seals last longer Hoses and gaskets won’t deteriorate Low system pressure puts less stress on hoses and cooling system plumbing.

11 Environmentally Friendly
Evans Waterless HDTC contains an inhibitor that lowers the toxicity of ethylene glycol. Disposal and replacement costs are reduced or eliminated. 80% of coolant produced goes to refill or top off leaking cooling systems. Only 12% of all antifreeze produced in the United States is recycled each year. Fuel savings mean less carbon dioxide emissions: A 3% fuel savings = 5,550 less lbs of CO2 emissions annually.* A 5% fuel savings = 8,800 less lbs of CO2 emissions annually.* *Average of 50,000 miles per year , 6 mpg 22.2 lbs of CO2 emitted per gallon of diesel).

12 Evans Waterless HD Thermal Coolant
A blend of glycols, soluble additives, and no water. Boiling point: 375o F, freezing point: <-70o F. Low conductivity – no “battery effect”. HDTC is a lifetime coolant if it does not become contaminated with water. Reduced Toxicity

13 Why is “Waterless” so Important?
What is Good about Water in a Coolant? Water has been the choice for cooling engines for over 100 years for very good reasons: 1. Water is cheap. 2. Water is available. 3. Water has superior thermal conductivity - in its liquid state.

14 What is Bad about Water in a Coolant?
The low boiling point of water (212o F to 220o F) becomes the failure temperature of traditional cooling systems. Water is corrosive and promotes electrolysis between dissimilar metals within the cooling system. Localized boiling causes vapor pockets that interrupt heat transfer; water retains just 4% of it’s thermal conductivity when it changes to vapor. The energy that it takes to maintain coolant temperatures below the boiling point of water is a huge waste of fuel.

15 Thermal Conductivity Comparison
Energy is consumed to keep coolant temp below boiling point and prevent vaporization. Evans HDTC removes the barrier, saving energy and fuel.

16 the boiling point of water is no longer a limitation.
Evans HDTC Separates the Boiling Point of the Coolant from its Operating Temperature. An engine operating temperature of 230o F is more than 100o F less than the boiling point of Evans HDTC. Evans Waterless HDTC decreases formation of vapor. In the case of water based coolants, the glycol component of the vapor condenses readily, leaving water vapor. The temperature at which water vapor condenses is the boiling point of water, not the boiling point of water based coolants. Heat transfer is not interrupted by insulating layers of water vapor. With Evans HDTC the boiling point of water is no longer a limitation.

17 Coolant Failure Temperatures
Typical coolant operating temperatures are near the failure temperatures of water-based coolants (bottom curve) but are much colder than the failure temperatures of HDTC (top curve).

18 Evans Waterless HDTC Unlocks a Reserve Capacity.
With Evans HDTC, the huge separation between operating temperature and coolant boiling point unlocks a reserve capacity. The reserve capacity increases the engine’s capability to operate safely at higher temperatures, without introducing thermal stress. Under high thermal stress conditions, Evans HDTC will run warmer but the cooling system will not fail; metal temperatures remain under control. Cooling system continues to function after shut down: No after boil. No increase in system pressure. Engine can be restarted at any time.

19 Evans has a Demonstrated History of Resolving Heat Transfer Issues. .
There are thousands of successful conversions worldwide. Most of these installations answer acute engine cooling problems that have defied solution by conventional coolant means. Evans waterless coolants offer solutions that save money and enhance performance. Evans Waterless Heavy Duty Thermal Coolant Proven Economic, Environmental, and Performance Advantages!
