Evaporative Condenser Pre-Cooling Units - FesChill

FesChill evaporative pre-cooling systems increase the efficiency and capacity of chiller groups and dry refrigerants, offering a COP 35% increase in effectiveness. They are economical and environmentally friendlys.

The condenser air inlet of the air cooled chillers is cooled by FESChill units with a very low cost. Easily-to-install on all types of condensers, the evaporative cooling pads are kept moist by simple water circulation. The air is pulled through the pads and then through the condensers by the existing fans of the condenser. The wet pads cool the air to wet bulb temperature, which becomes cooler before entering the condenser.

Using the air cooled in this manner, the condenser works much more effectively enabling the increase of the cooling performance and the decrease in the energy consumption of the chiller. The break-down risks decreases, the system and the condenser life-time increased together with the global working performance ( EER or COP ) of the system.

Why FesChill?

The table below illustrates the savings for Air cooled condensers using and not-using the FesChill unit. The energy used by the Chiller is decreased by 19 % and the cooling capacity is increased by 11 % as a result of a 11°C decrease in inlet air.

The EER or COP of the chiller can increase by 36 %. The condenser effectiveness increases on average by 2 % with every 1.8°C decrease of air inlet temperature achieved by the pre-cooling pads.
