Key benefits of the Variable Speed fan kits
Key benefits Improve Sound Perception Saving Energy Condensing Pressure Control Three key benefits for the end user
Condensing pressure control The benefits of the condensing pressure stabilization are: Ø Stable evaporating temperature Ø Avoid flash gas Ø A better evaporator optimization during full year The kit « READY TO INSTALL » optimize the Tecumseh condensing units.
Saving energy Ø 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. ØAs an example in a positive application the end user save up to 107 € per year. 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. Details on the appendix 24 The Tecumseh solution saves the end user money !

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 • Less than 3 year pay back • • • Low start up and stop noise • Lower power consumption • A significant gain of energy Easy to mount • Simple supply chain with the all • in one kits. (no risk of missing parts) Quick installation
Press release of the kits Ø Chillventa : Official launch Ø Press release: during October 2012 on major European media.
Technical features
Give a response to the winter evaporator degradation ØWhen 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
