3 1.Tecumseh product offer  « READY TO INSTALL » for new installation and adaptable for the retrofit systems  A specific solution for all fan technologies offer by Tecumseh.  An all-in-one solution.  A pre-set kit: 16 Bars for R-404A, an 10 Bars for R-134a.

4 AC fans all diameters - All Condensing units except AJ silence and Wintsys panels 1 and 2 - One cable (power supply) EC Ø 350mm fans - For AJ silence 4517, 4519 and Wintsys panels 2 - Two cable (power supply and control) EC Ø 250/300mm fans - For AJ silence and Wintsys panels 1 - One cable (power supply) Tecumseh fans description AC: alternative current EC: Electronically commutated Tecumseh introduces variable speed on all its fan motors

5 Variable Speed fan availability Specific logos and stickers :  Easy identification for wholesalers and installers  The “variable speed” stickers on the fan indicate the opportunity to install a Tecumseh variable speed kit.  A specific logo sticker will be applied: When the condensing unit is able to handle the variable speed kits one of the fans assembly spare parts

6 Existing power supply Pressure information coming from liquid line AC single phase fan The fan speed controller adjusts the fan speed AC solution description  Only one operation for the wiring  An easy plug on the fan speed controller  No impact on the existing power supply line A complete and proven solution.

7 AC kit content « READY TO INSTALL » AC kit content:  Two preset fan speed controllers for commercial application : R-404A or R-134a  Specific brass tees with screw connection and Schrader valve  Specific cable for fan speed controller  Installation instruction and a quick start manuals

8 Power supply 230V 50Hz Pressure information coming from liquid line EC Ø 250/300mm solution ESM+ plug A quick and innovative solution  Remove the power supply cable by the specific ESM+ plug  An easy plug on the fan speed controller  The condensing pressure is directly connected to the fan by the module. The fan speed controller adjusts the fan speed

9 EC Ø 250/300mm kit content « READY TO INSTALL » EC Ø 250/300 mm kit content:  Two preset fan speed controllers for commercial application: R-404A or R-134a  Specific brass tees with screw connection and Schrader valve.  Specific cable with ESM+ module  Installation instruction and a quick start manuals for ESM+ module and controller

10 Pressure information coming from liquid line EC Ø350mm solution Simplest solution on the market Power supply 230V 50Hz  No power supply modification  An easy plug on the fan speed controller  The condensing pressure is directly connected to the fan by the module. The fan speed controller adjusts the fan speed

11 EC Ø 250/300mm kit content The « READY TO INSTALL » EC kit content:  Two preset fan speed controllers for commercial application: R-404A or R-134a  Specific brass tees with screw connection and Schrader valve.  Installation instruction and quick start manuals

13 Key benefits of the Variable Speed fan kits

14 Key benefits Three key benefits for the end user

15 Condensing pressure control The benefits of the condensing pressure stabilization are:  Stable evaporating temperature  Avoid flash gas  A better evaporator optimization during full year The kit « READY TO INSTALL » optimize the Tecumseh condensing units.

16 Saving energy The Tecumseh solution saves the end user money !  for a year round example the « READY TO INSTALL » EC fans kits can save up to 8% of the energy consumption of the Condensing unit.  As an example in a positive application the end user save up to 107 € per year. Details on the appendix 24 Comparison between electrical consumption of an electronically commutated (EC: blue line) and a standard shaded poles fans (AC: red line) both equipped with variable speed controller.

17 Decrease the sound impact Speed rotationMin25%50%75%100%LW(A) EC Diam. 250mm dB(A) EC Diam. 300mm dB(A) EC diam. 350mm dB(A) On the appendix 25 please find an example with a condensing unit. More than a soft start, EC technology offers a significant sound reduction

18 Benefits for the installerBenefits for the end user Maintain the condensing pressure = Constant evaporating temperature Less short cycle for the fan and the compressor Avoid flash gas Expend the life time of your refrigeration complete system Less maintenance The evaporator is always used on its optimum position Improved food preservation (hygrometry control) Expend the life time of your complete refrigeration system A fans “soft start” Low start up and stop noise Decrease the noise perception during winter and low consumption needs periods A direct gain below 25°C Lower power consumption A significant gain of energy Less than 3 year pay back Easy to mount Simple supply chain with the all in one kits. (no risk of missing parts) Quick installation From the wholesalers to the end user

19 Press release of the kits  Chillventa : Official launch  Press release: during October 2012 on major European media.

20 Technical features

21  When the ambiant temperature decrease the evaporating temperature dropt also. This lead: Icing the evaporator Flash gas Decrease the global lifetime Decrease the global COP Expansion valve not well adapted Give a response to the winter evaporator degradation Insure a smoother running condition
