Are BluVac compatible with A2L systems?

Yes, BluVac gauges can be used on any type of refrigeration system regardless of the refrigerant type including A2L  provided that the system does not contain beyond trace amounts of refrigerant. The BluVac is not intended for use with pressurized refrigerants of any kind. The BluVac like all thermistor vacuum gauges is not accurate with refrigerant still in the system beyond trace amounts. Follow industry best practices with any refrigerant type including A2Ls and assure that the refrigerant is removed properly and the system is swept with nitrogen to remove residual refrigerant. Pressure test for leaks before commencing evacuation and connecting a BluVac gauge. That said, we have been working with A2L refrigerants for years without issue, specifically R1234yf and R454A and R454B are all common. The hype is with the transition in mass to R32. R32 training specifically, also suggests that the system is purged with nitrogen prior to service.

Which refrigerants are classed as A2L?

R–1234yf (Honeywell), R–1234ze (Daikin), R–454C (Chemours), R–455A (Honeywell), R–454A (Chemours), R–454B (Honeywell), R–447A, R–32, and R–452B (Honeywell). As with A1 refrigerants, some A2L refrigerants are pure, and others are blends. The pressure, temperature, and viscosity of A2L refrigerants vary by each refrigerant type.

 Also, A2L refrigerant is hard to ignite, the risk is extremely (and I mean extremely) low.

When you look for an edge, what do you need?

From the BluVac+ Pro to the BluVac+ Micro, AccuTools has you covered. The revolutionary BluVac+ family of Digital Vacuum Gauges utilizes patented technology to bring you the accuracy of a scientific gauge in a field-ready tool. Our BluVac+ gauges outperform all others and address the problems previously encountered with other micron gauges such as sub-par accuracy, loss of calibration, or having to guess if the gauge is contaminated with oil. With self-diagnostic sensors and field calibration, the BluVac+ family of gauges will increase your productivity and never leave you guessing about your work or questioning your tools in any environment.

The complete line is paired with the powerful BluVac app for an improved evacuation experience. You get a better understanding of what you’ve been missing – leaks, moisture, and outgassing. With proper evacuation, systems will run better, last longer, and experience fewer problems for a lifetime.
