Digital Recovery Machine
The MR45 refrigerant recovery machine is the first variable-speed DC motor recovery machine with a digital display. Pump refrigerant more easily and quietly than ever before. Connect hoses without navigating around dark tight spaces or picking the pump off the ground. View status messages and pressures directly on the big bright display.
Carry the machine to and from the job site easily and well protected from environmental hazards. Turn the single rubberized control valve to route refrigerant through MR45, and use the self-purge function to pump the last traces into the recovery cylinder instead of being left in the machine or released into the environment.
Features include:
- Protects from voltage drop (runs as low as 95 VAC)
- Single dial self-purge
- Twice the RPMs (3,000) and twice the horsepower (1HP) with DC Motor
- Extra large condenser cools faster, especially on hot days
- Only 22 lbs
- Water resistance to withstand direct rain
- Easy access ports
- Long life and low friction with ceramic cylinders
- Dual cylinder compressor
- Easy hose connections and built-in power cord storage
- Large backlit display with status messages
- Class A2L compatibility for a wide range of jobs

Recovery methods

Direct Liquid/Vapor Recovery – This is the typical recovery method. Vapor and liquid lines are routed through your manifold, into MR45, and out to the recovery cylinder
Push/Pull Recovery – This method is only for larger systems with at least 30 lbs (14 kg) of liquid refrigerant. It is used to recover liquid before recovering vapor
