This series of rooftop air-conditioning systems is ideal for a broad scope of commercial vehicles. The range starts from mini buses seating up to 10 seats to specialty vehicles such as ambulances and fire engines and in agricultural and construction industry vehicles. Featuring constant airflow provision resulting from the integration of high-efficiency, durable fans and blowers, these systems are not only highly reliable, but renowned for their long service life.

A variety of available accessories for vehicle-specific retrofitting includes control units, air vents and ducts as well as installation kits. The units can be customized right down to painting in vehicle colors.
