ECO AIR COOLER
The VIGIA system keeps tire pressure constant. It warns the driver in the event of tire pressure reduction, and automatically activates the inflation process at the same time. Having the system increases driver safety and improves efficiencThe air-conditioning of the cabin is one of the most important elements that contribute to the comfort of the vehicle. That is why COLVEN developed the VIESA Eco Air Cooler, complying with highest environmental standards, generating welfare to the drivers all around the worldy.

However high the outside temperature, the VIESA system creates a cool climate inside the cabins. VIESA is leader in Argentina and is the best selling cooler from Europe and Australia, due to its high performance, low consumption and by no using pollutant gases.
