ooling water, beforehand heated by the vehicle, run on coil. In the same time, fan unit blows fresh
air through the heat exchanger. Then, air temperature rise up. Finally, air output evacuate hot air.
Operating conditions:
Product must be on a ventilated place.
Operating temperature have to be between -30° and +80° .
ooling fluid must be antifreeze and anticorrosive for copper and aluminum. Use a cooling fluid
