Achieves up to 30% energy saving
Fes Chill Units cool the intake air of air-cooled condensers through evaporative cooling at very low costs.
Evaporative cooling pads, which are easily installed in front of all types of air-cooled condensers, are kept constantly wet by a small water circulation pump.
The existing fans of the condensers draw in outdoor hot air through the wet pads, lowering the air temperature closer to the wet-bulb temperature.
This cooled air then passes over the condenser coils.
As a result, the condenser operates more efficiently, cooling performance increases, the energy consumption of the chiller units decreases, system efficiency improves, operating pressure drops, the lifespan of the system and compressor is extended, and the risk of failure is significantly reduced.
Cooling the intake air of the condenser lowers the system’s operating pressure and reduces the power consumed by the compressor, while simultaneously increasing cooling capacity.

Documented Performance Gains with FesChill Units
The table above presents a comparison of performance values measured before and after installing FesChill units for pre-cooling the condenser of a chiller system.
After pre-cooling was applied, the intake air temperature to the condenser dropped by 11°C, resulting in the following improvements:
🔻 19% reduction in electrical power consumption by the chiller
🔺 11% increase in cooling capacity
🔺 36% improvement in COP (Coefficient of Performance)
Moreover, for every 1.8°C (≈3.2°F) drop in ambient air temperature at the condenser inlet, the condenser efficiency increases by approximately 2%.
