Variable Speed fan availability
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
Specific logos and stickers :  Easy identification for wholesalers and installers

The kit « READY TO INSTALL » optimize the Tecumseh condensing units.
Saving energy
 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.

an electronically commutated (EC: blue line) and a
standard shaded poles fans (AC: red line) both
equipped with variable speed controller.

More than a soft start, EC technology offers a significant sound reduction
From the wholesalers to the end user
Benefits for the installer
Maintain the
condensing
pressure
=
Constant
evaporating
temperature
A fans “soft
start”
•
•
•
Less short cycle for the fan and
the compressor
Avoid flash gas
Expend the life time of your
refrigeration complete system
Benefits for the end user
•
•
•
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
Decrease the noise perception
during winter and low consumption
needs periods
A direct gain below 25°C
•
•
•
Low start up and stop noise
•
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
Press release of the kits
 Chillventa : Official launch
 Press release: during October 2012
on major European media.
Technical features
Give a response to the winter evaporator degradation
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
Insure a smoother running condition
