The roof-mounted bycool R-Evolution evaporative cooling system is perfect for reducing the internal air temperature of the cabin due to the evaporation process that cools the external fresh air before being delivered into the cabin area.

The bycool range of evaporative coolers are built to provide truck sleeper cabs with cool comfort during rest breaks.
The units are designed to be used whilst parked with the engine switched off, however it is also possible to have the units running while driving to aid in the cooling process of the sleeper cab area.
The evaporator works by cooling warm external fresh air as it passes through the unit’s wet filter. As the external air moves through the filter the water evaporates, cooling the air. The cool air is then blown through the internal vents to cool the cab area.
