Climate Control Unit

The operation of the A/C System is controlled by an advanced electronic Climate Control System located in the Return Air plenum of the rooftop unit. The location of the Electrical Panel provides an easy service access from the bus cabin.

The CCC System was specially developed by Coachair for Bus & Coach air-conditioning applications.

Custom designed solid-state devices are used in place of conventional switching relays to control the power supply to the motors providing extremely reliable operation.

The system is modular in nature allowing quick and easy replacement of components during servicing.

Electric Series – EX26 / 32


The EX model is designed for a range of alternative fuel buses, including electric, hybrid and hydrogen. This unit has the highest capacity with the lowest power consumption of any full electric unit on today’s market.

Due to the two smaller DC voltage compressors, the roof top weight is over 50% lower, compared to alternate product currently available on the Australian market.

This unit has the lowest whole of life cost, compared to similar electric bus HVAC units on the market today.
