Refrigerant Gases Detectors

The environmental impact associated with the use of refrigeration and air conditioning equipment has brought about changes in the composition of refrigerant gases and in the way they are being used.

Refrigerant gases are used as a heat exchange material in equipment such as refrigerators, freezers and air conditioning systems. The refrigerant gas is pumped round a closed loop, being repeatedly evaporated, condensed and transferring heat away from where it is not required.

The original chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) were highly efficient refrigerants, however their environmental impact has lead to the banning of CFCs and the phasing out of HCFCs
However, while their common replacement, hydrofluorocarbons (HFCs), provide a non-ozone depleting solution, they still have a high global warming potential (GWP).

Among the gases of concern are R22, R123, R125, R134a, R404a, R407a, R407c, R410a, R507, R1234yf as well as SF6.

Ammonia, SO2 and CO2 are also used in refrigeration systems – and these gases can be toxic at elevated levels.

For environmental and safety reasons it may be necessary to monitor for these gases. CSL offers a range of fixed gas monitors for the detection of refrigerant gases. See the products below for a range of gas monitoring options.
