Fieldpiece MR-45 Digital Refrigerant Recovery Machine Review

Updated March 2024.

Today we will be reviewing the Fieldpiece MR-45 Digital Refrigerant Recovery Machine. Fieldpiece is known as a leader in the HVAC meter market but surprisingly this is their first foray into refrigerant recovery. They entered the market beautifully with a variable smart speed 1 HP DC motor that is encased in a water resistant case to withstand direct rain. This refrigerant recovery machine offers roughly twice the RPMs (3000) and HP than that of its competition.

The Fieldpiece MR45 digital recovery machine focuses a lot of its attention on the recovery of vapor with market leading vapor recovery rates for the most common refrigerants. Fieldpiece also put an oversized condenser to cool faster and improve performance on those hot days in the dead of summer. With Fieldpiece being based in California it is not too surprising to see they put an emphasis on the increased condenser size as they can experience plenty of days when the mercury rises above the 100 °F mark.

The Fieldpiece MR45 Digital Refrigerant Recovery Machine comes in at a slender 22 lbs and again leads the pack in the parameter. Another key addition to this model is the bright blue Fieldpiece digital display. The single dial simplifies operation and the recovery can be throttled with the dial to reduce liquid slugging and knocking.

Rounding out the MR45 is easy access ports for easy hose connection and built in storage for the power cord. One other interesting feature is the ability to operate under low voltage situations when a voltage drop occurs. The Fieldpiece MR45 digital refrigerant recovery machine has a dual cylinder compressor with the cylinders being ceramic coated for long life, low friction operation. All in all the Fieldpiece MR45 is a great entry into the competitive refrigerant recovery machine market.
