The 720 Alpha is a split system designed to provide optimum performance in medium sized box bodies that are insulated for fresh or frozen produce transport. The system uses environmentally friendly R404A refrigerant and is suitable for temperatures down to -25°C.

The system comprises a condenser with a 20 series 4 fan evaporator, with or without electric standby, a compressor (with mount kit compatible to your vehicle) and in-cab digital controller that is fully programmable and will provide a constant temperature readout. It features automatic defrost but manual defrost can be initiated by push button control.

The refrigeration system is driven using a compressor that is mounted within the engine compartment and belt driven from the vehicle engine crankshaft. When the vehicle’s engine is running and the thermostat calls for cooling, an electro-magnetic clutch on the compressor is engaged enabling the unit to provide refrigeration. A semi-hermetic compressor powers the refrigeration system on mains standby.

Optional accessories include:
A datalogger and TWice™ Dual Temperature System for fresh and frozen multi-compartment refrigeration.
