GDA 3160 : Flush Mount Refrigerant Gas Detector
The GDA 3160 is a low profile wall mounted refrigerant detector for use in offices and laboratories where a gas sensor needs to appear non obtrusive. The sensor uses the lastest in NDIR techniques for detecting a wide range of refrigerant gases and is therefore immune from cross sensitivity to other gases.
Designed, manufactured and supported locally in Australia.
It has 4-20 mA o/p and interfaces to the full range of GDA control units and will interface to BMS and SCADA. It is designed to fit into a Clipsal double gang GPO wall mount with a total protrusion from the wall of 13 mm.

| 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 R134a, R407 and R410a. 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, R410a, 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.
