NEW KENSINGTON, Pa. — Bacharach Inc. adds R-514A to its gas library of detectable refrigerants as chiller applications within the refrigeration industry demand refrigerants with low-global warming potential (GWP). Bacharach’s proprietary non-dispersive infrared (NDIR) technology allows its instrumentation to measure levels as low as 1 ppm of refrigerant, while maintaining high accuracy and enabling the early detection of refrigerant leaks.

“The calibration curve for R-514A has now been added into the software for our multi-zone and single-zone continuous refrigerant monitors as well as our portable spot leak detection devices. Our proprietary sensor technology allows us to create these curves quickly to keep up with the development of new and better refrigerants. This enables the precise measurement of all refrigerants, including the new products like R-514A, to maintain the high standards expected from Bacharach’s market leading sensor technology,” said Tom Burniston, product manager, fixed instruments. “Bacharach’s NDIR sensors allow for fast response times, long sensor life, high accuracy, repeatability, minimal maintenance, and no cross sensitivity,” he said.


R-514A is a refrigerant with a very low-GWP of under 2 and is targeted as a replacement for R123 in centrifugal chiller applications. It is a blend of hydrofluoroolefin (HFO) 1336mzz(Z) (74.7 percent) with trans-1,2-dichloroethene (25.3 percent).

ASHRAE 34 classes R-514A as a “B1” refrigerant, meaning that it is not flammable but is classed as having higher toxicity, with on occupational exposure limit (OEL) of 323 ppm. This highlights the importance of the early detection of refrigerant leaks, which could be harmful and reduce refrigeration system efficiencies.

About Bacharach products accepting the new R514A refrigerant:

1.      HGM-MZ — Fixed leak monitor for up to 16 remote areas detecting refrigerant levels as low as 1 ppm. Configurations are also available to monitor CO2 and NH3.

2.      HGM-SZ — Fixed leak monitor for one location to detect and measure chlorofluorocarbon (CFC), hydrofluorocarbon (HFC), and hydrochlorofluorocarbon (HCFC), leaks down to 1 ppm. Configurations are also available to monitor CO2 and NH3.

3.      PGM-IR — Portable leak monitor for halogenated refrigerants or CO2. Unaffected by changes in temperature and humidity, detecting limits as low as 1 ppm enabling quick, thorough inspections and leak surveys.

4.      H25-IR — Industrial grade leak analyzer for white goods manufacturing, eliminates the need for a calibrated reference leak source while detecting CFC, HFC and HCFC refrigerants down to 0.03 oz/year (0.85 g/yr).

Bacharach continues its support of the cooling and refrigeration industries by the expansion of R-514A to its library of refrigerant gasses — offering more gasses to be detected and monitored while assisting in the use of refrigerants less harmful to the environment.
