MR45INT vs MR53INT – Which Fieldpiece Recovery Machine Is Right for You?
If you're in HVACR, you know how important it is to have the right tools for the job. When it comes to refrigerant recovery, speed, safety, and reliability are key. That’s where the Fieldpiece MR45INT and MR53INT come in.
Both machines are built to get the job done quickly and safely — but they’re designed for slightly different needs. Whether you're working on everyday jobs or handling flammable refrigerants in hazardous areas, there’s a tool that fits.
Let’s take a look at the main differences to help you decide which one belongs in your van.
The MR45INT is a solid choice for technicians who need a powerful, reliable recovery machine for day-to-day use.
What makes it great:
Fast recovery speed thanks to a variable speed DC motor (2,000–3,000 RPM).
Built to last, with rugged housing that’s designed for tough conditions.
Light and easy to carry, weighing just 10kg.
Simple controls with a single dial valve and a clear digital display.
Rated for use with A2L and A1 refrigerants, including R32.
This Recovery Machine is great for fast and efficient recovery on-site.
The MR53INT takes everything great about the MR45INT and adds some extra protection for working in riskier areas.
Important features of the MR53INT:
ATEX rated, so it’s safe to use in potentially explosive atmospheres.
Works with A3, A2L, and A1 refrigerants, so you're covered for more types of jobs.
Same fast DC motor and digital display as the MR45INT.
Just as portable, with a tough design that’s lightweight.
If you’re working with flammable refrigerants or in environments where safety is a top concern, the MR53INT is perfect for you.
Choosing between the MR45INT and MR53INT depends on the demands of your work. If you're handling standard refrigerants and need something fast, durable, and easy to operate, the MR45INT is a practical choice for everyday use. If you're working with flammable gases or in potentially explosive environments, the ATEX Rated MR53INT is specifically built to meet those safety requirements.
At the end of the day, both machines are built to help you work easier, faster, and better — giving you more time to focus on what matters: getting the job done right.
