Bycool evaporative units are cooling systems for truck cabins and other vehicles which use the natural evaporation of water, either with the engine running or switched off, both during the day and night. Unlike conventional air conditioning systems, Bycool uses natural principles to cool the air:
“When liquid evaporates, it absorbs heat”.

Bycool Dirna evaporative systems are based on the same principle. The hot outside air passes through a damp filter where the water evaporates, absorbing the heat and cooling the air. The fresh, pure air obtained acts like a breeze, quickly and naturally cooling the skin. Bycool Dirna evaporative systems improve general comfort and consume less energy. The continuous air which enters and leaves the cabin, fresh and renewed, will remove the sensation of heat.

100% Ecological
Bycool units can run with the vehicle engine switched off, thus avoiding engine idling and the subsequent atmospheric emissions of CO2, and are compatible with the requirements of the North American Environmental Protection Agency (EPA) and with EU regulations on anti-idling in haulage vehicles (parking coolers).

Fuel saving
Fuel cost savings are achieved when using the unit overnight, since the engine does not need to be idling, thus allowing proper rest inside the cabin during the summer months. The same occurs with logistics stops for the loading and unloading of goods during the day, when the unit can be used for climate control inside the cabin. The unit increases road safety by allowing proper rest and sleep through the use of air conditioning in the cabin without the engine running.

Maximum comfort
With Bycool Dirna evaporative systems you can enjoy fresh, clean, continuously renewed and oxygenated air in a completely natural manner during the day or night, allowing you to work and rest more comfortably.

- Bycool evaporative systems work with the engine switched off, making them ideal for use during goods loading and unloading operations, rest periods, at night and during compulsory stoppages.
