Bacharach, manufacturer of refrigerant gas leak detection and monitoring instruments, and combustion and emission analysers, has added the more environmentally friendly R514A to its gas library of detectable refrigerants.

Bacharach’s proprietary Non-Dispersive Infrared (NDIR) technology allows its instrumentation to measure levels as low as 1ppm of refrigerant, while maintaining high accuracy and enabling the early detection of refrigerant leaks.

Tom Burniston, Product Manager, Fixed Instruments stated, “The calibration curve for R514A 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 R514A, to maintain the high standards expected from Bacharach’s market leading sensor technology.”

“Bacharach’s NDIR sensors allow for fast response times, long sensor life, high accuracy, repeatability, minimal maintenance and no cross sensitivity,” Burniston added.

R514A is a refrigerant with a very low global warming potential (GWP) of under 2 and is targeted as a replacement for R123 in centrifugal chiller applications. It is a blend of HFO 1336mzz(Z) (74.7%) with trans-1,2-dichloroethene (25.3%), a gas not previously used in refrigerants.

Bacharach products:

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 CFC, HFC, and 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 analyser 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).

The company continues its support of the cooling and refrigeration industries by the expansion of R514A 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.
