| Refrigerant Plant Room Monitoring | Refrigerant gases are used to provide a means of cooling the evaporators in freezers and air conditioning for plant rooms and chiller plants. Historically CFC refrigerant gases such as R11, R12 and R22 have been used. CFC’s are ozone depleting gases and are now being phased out and replaced by ozone friendly gases such as R134, R407 and R410. Why is there a need to detect them?
Gas Detection Australia has a range of ultra-low level refrigerant gas leak detection systems specifically developed to prevent the expensive results of refrigerant gas leaks for R22, R123, R134a, R404, R407, R410, R514a, R1234yf and many others. Meets the requirements of AS/NZS 5149.3:2016 and ISO 5149-3:2014 Designed, Manufactured and Supported in Australia. |
| Air Conditioning Monitoring | Air conditioning gas detection systems are used in a number of ways. In air conditioning plant rooms Gas Detection Australia has gas sensors and gas detectors for Ammonia , Propane, CO2 and R134a, R123, R125, R404, R407c R410a etc. In enclosed laboratories classrooms and workspaces. The Gas Detection Australia range of flush mounted Air Conditioning gas sensors for Carbon Dioxide GDA 4360 are used by the HVAC industry to control fresh air input into rooms and modulate supply. In the case of VRF systems needing room air conditioning gas detection HVAC industry uses the flush mounted GDA 3160 which are unobtrusive and used to detect low levels of R134a, R123, R404, R407c, R410 etc. Meets the requirements of AS/NZS 5149.3:2016 Designed, Manufactured and Supported in Australia. |
