November 28, 2017, Pennsylvania, United States: US-based Bacharach, manufacturer of refrigerant and gas leak detection equipment, from monitoring instruments and data solutions to combustion and emissions analysers, announced the addition of two new gas options, R514A and R452B for its MGS-250 infrared refrigerant gas detector product family. ASHRAE 34 classes R514A as a “B1” refrigerant, meaning that it is not flammable, but is classed as having higher toxicity, with on OEL of 323ppm, Bacharach said. And it classes R452B as an “A2L” refrigerant, meaning it is classed as non-toxic but is mildly flammable, Bacharach added.

According to Bacharach, the non-dispersive infrared sensor technology offers significant user benefits when detecting either of the two gases. The major benefit, the company said, is the elimination of cross-interference from other gases and the elimination of cross-interference from changes in temperature and humidity, providing users with peace of mind knowing the reading they see is accurate and stable. Other benefits, the company added, include added sensor life of 5-7 years and reduced maintenance.

Modbus RTU protocols, analogue and relay outputs enable easy integration with building management systems and industrial automation system controls for refrigeration systems operating with R514A or R452B.

Bacharach said it continues supporting the cooling and refrigeration industries by extending its library of refrigerant gases that can be detected and monitored, as the refrigeration industry moves toward the use of refrigerants less harmful to the environment.
