The MSDE11 is an 11kW dual evaporator split system air conditioning unit. The evaporators are purposely designed to be mounted externally on the vehicle. This evaporator configuration is ideally suited if limited space is available inside the vehicle.

Each evaporator unit has a cooling capacity of 5.5kW and contains a dual scroll blower mounted with a single evaporator core. The aircon outlet interface can be modified to suite any vehicle hull profile. If fresh air supply is required, provision has been made in the evaporator design to mount an additional fresh air fan unit.

A choice of two condenser configurations is available with this air-conditioning system: A condenser pack that is mounted inside the engine bay that utilizes the engine cooling fan and a second option of an enclosed condenser unit that is mounted on the outside of the vehicle containing condenser heat exchanger cores and cooling fans.

The aircon control is done via the SME developed multi application controller (MAC) the MAC can interface with the vehicle control to for a total integrated system solution. Alternatively the HVAC control also can be done with conventional dash mounted switches.

The compressor is mounted in the engine bay and belt driven from the engine pulley.
