Abstract
A refrigerant recovery assembly will recover incompatible refrigerants. The assembly has two separate processing units. Each unit has a pair of hoses which connect to an air conditioning system for recovering refrigerant. Each unit has an expansion valve, an evaporator, a compressor, a condenser and one or more filters. The two units are mounted on a single frame and utilize common electrical controls. The electrical controls will not allow each unit to operate simultaneously. A single vacuum pump is used with each unit.
