Description

The Fieldpiece MR45INT represents a modern and advanced solution for refrigerant gas recovery in HVAC/R applications. Equipped with an intelligent variable-speed DC motor, this recovery unit automatically adjusts its power to optimize recovery in both liquid and vapor phases, delivering high performance even under variable supply voltages or suboptimal power conditions.

The large condenser and dual-cylinder oil-less compressor ensure efficient recovery, while the backlit LCD display with status messages makes it easy to monitor real-time operation. Thanks to its lightweight design (approximately 10 kg) with easily accessible connection ports, it is convenient to transport and use in the field. This model also includes an automatic purge system that maximizes recovery efficiency and minimizes residual refrigerant in the machine.
