MGS-250 Now Detects R-514A and R-452B
This non-dispersive infrared sensor technology offers significant user benefits when detecting either of these two gases. The major benefit is the elimination of cross-interference from other gases and the elimination of cross-interference from changes in temperature and humidity providing the user with peace of mind knowing the reading he sees is accurate and stable. Other benefits include added sensor life of 5 – 7 years and reduced maintenance.
Modbus RTU protocols, analog and relay outputs enable easy integration with building management systems and industrial automation system controls for refrigeration systems operating with R-514A or R-452B.
Bacharach continues supporting the cooling and refrigeration industries by extending its library of refrigerant gases which can be detected and monitored, as the refrigeration industry moves toward the use of refrigerants less harmful to the environment.
R-514A is a refrigerant with a very low GWP of under 2, and is targeted as a replacement for R-123 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.
ASHRAE 34 classes R-514A as a “B1” refrigerant, meaning that it is not flammable, but is classed as having higher toxicity, with on OEL of 323 ppm.
This B1 classification highlights the importance of refrigerant monitoring in this application, maintaining high accuracy and enabling the effective and reliable detection of refrigerant leaks which could be harmful, as well as reducing the efficiency of the refrigeration system.
R-452B is designed as a lower GWP replacement for R-410A in air conditioning applications, with a GWP of 676 which is around 65% less than that of R410A. It is an HFO/HFC blend of R-32 (67%), R-1234yf (26%) and R-125 (7%).
ASHRAE 34 classes R-452B as an “A2L” refrigerant, meaning it is classed as non-toxic but is mildly flammable.
Reliable and accurate monitoring of A2L-classified refrigerants is an important factor in complying with regulations and assisting the safe use of refrigerants.
