Fieldpiece USA - MR45INT - Digital refrigerant gas recovery unit 1 HP - 0,75 Kw - 430 kg/hour in push/pull mode (R410A)

High performance recuperator with digital display; 1 HP (0.75 kW) "smart" mode variable speed DC motor.

The Fieldpiece MR45 high-performance recuperator has a built-in monitoring system that adjusts engine performance to handle liquid and run twice as fast on steam.

With a powerful 1 HP motor and large capacitor, this machine excels on the longest, hottest jobs.

The easy-to-read display, the light weight (10 kg), the straight inlet/outlet connections, facing outwards and in a higher position with respect to the ground, the single display make this recovery unit easy to use and resistant to use daily, even in the rain.




The intelligent mode variable speed DC motor is quieter, faster, smoother and lighter, thus providing superior comfort and performance.

Slugging is minimized and vapor recovery is maximized.

The advanced motor control function also regulates it to match the input voltage and allows the machine to operate both with longer extension cords and in the event of mains overcapacity during hot days.
