An adiabatic cooler is a combination of a dry cooler with an adiabatic pre-cooling section . This pre-cooling section lowers the ambient air temperature by evaporating water that passes through the cooling/humidification panels, which are specially designed for this purpose.
Dry mode:
The fluid is cooled inside the vertical coils by the flow of ambient air. Ambient air is drawn through the coils by fans mounted centrally on the top of the cooler; the humidification panels located in front of the coils are dry.
The fan speed is controlled by an inverter based on the thermal load to maintain the fluid outlet temperature at set point values. The hot air is then expelled upwards.
Adiabatic mode:
When dry cooling is not effective and the ambient temperature reaches a predetermined set point, water flows over the panels (pads). The ambient air is cooled by evaporation as it passes through the panels: this pre-cooled air then passes through the tubular coils and cools the fluid.
The water that has not evaporated on the panels is collected in a stainless steel tank and then recycled from a sump. Water savings are therefore significant and do not require water treatment, with no risk of legionella.
Adiabatic coolers comply with standard NF E 38-424 of December 2020.
They offer the following advantages and features:
Easy maintenance thanks to the vertical "H" shape of the tubular coils, which allows full access through the central door.
Below are the main areas of application:
Our TOPAZ adiabatic cooler combines a dry cooler with an adiabatic pre-cooling section, improving cooling efficiency, especially in critical environmental conditions.
The system uses water evaporation on special humidification panels, which lower the temperature of the air entering the coils.
