Agenda
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.
Tecumseh fans description AC: alternative current
EC: Electronically commutated
Tecumseh introduces variable speed on all its fan motors
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
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.

Key benefits of the Variable Speed fan kits
Key benefits
Three key benefits for the end user
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.
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.
Decrease the sound impact

EC Diam. 250mm 30 33 38 47 52 dB(A)
EC Diam. 300mm 29 29 47 48 60 dB(A)
EC diam. 350mm 18 21 42 53 70 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
Benefits for the installer Benefits 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 systemA 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
Press release of the kits
Chillventa : Official launch
Press release: during October 2012 on major European media.
Technical features
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
