The MDI 13 is a 13kW dual evaporator split system air conditioning unit. The evaporators are purposely designed to be mounted vertically inside the vehicle either against the back of the driver and co-driver seat or against the hull of the vehicle.

Each evaporator unit has a cooling capacity of 6.5kW and contains two dual scroll blowers that are mounted with a single evaporator core. The evaporator outlet is designed to connect with ducting and can be modified to suite any ducting interface.

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 of 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 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.
