A2L CompatibleAre You Ready for The A2L Refrigerant Change?

 April 1, 2024      Gabe Marsi

2025 is approaching fast, and it won’t be long before the R-454B systems will start appearing in the residential and commercial field. Some of the refrigeration tools must be compatible with all A2L refrigerants. One of the most important tools a technician must have for working on A2L systems is a new electrochemical refrigerant leak detector that is A2L compatible. The older leak detectors are not A2L compatible and will not detect the new A2L refrigerants such as R-454B (check with the manufacturer).

In the month of April, we are offering, at a discounted price, the PROWLER Leak Detector that will not just detect leaks, but will pinpoint them. You will have peace of mind knowing that the proprietary electrochemical sensor has a life span of more than 10 years and will not diminish over time or with usage. Plus, the manual calibration mode and reset control allow for precise detection. Enjoy the convenience of a mutable alarm with silent vibrating handle, a backlit LCD screen that tilts up for easy viewing at any angle, and a 17” flexible probe for those hard-to-reach-places. This detector detects all HFC, HCFC, HFO(A2L) and blended refrigerants.
