Feschill Evaporative Pre-Cooling System

FESCHILL

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.

Advantages of the Fes Chill Evaporative Pre-Cooling System

Does not wet the condenser – Ensures condenser surfaces remain dry.
Prevents limescale formation – No scaling on condenser fins or pipes.
Does not void the condenser warranty – Safe to use with existing systems.
Filters the incoming air – Helps protect condenser surfaces from dust and debris.
Lowest water consumption among evaporative cooling systems.
Stable operation – No on-off cycling; continuous and consistent performance.
No temperature fluctuations – Provides steady cooling conditions
Highly efficient – Maximizes system performance with minimal resources.
High evaporative efficiency – Up to 96% cooling effectiveness.
Extremely low energy consumption – Operates with minimal power.
Non-pressurized system – Does not require high-pressure operation.

Reduces mechanical stress and failures.

Why Choose FesChill ?

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.

(Based on a 26 kW air-cooled chiller unit using R22 refrigerant)

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%.
