This non-dispersive infrared sensor technology offers significant user benefits when detecting either of these two gases. The major benefit is the elimination of crossinterference 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 R514A or R452B.

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.

About R514A
R514A 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 HFO 1336mzz(Z) (74.7%) with trans-1,2-dichloroethene (25.3%), a gas not previously used in refrigerants.
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.
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.

About R452B
R452B is designed as a lower GWP replacement for R410A 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 R32 (67%),
R1234yf (26%) and R125 (7%).
ASHRAE 34 classes R452B 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.
