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

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

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
