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.

  • Standalone system or 4-20 mA, 0-20 mA, 0-5 V ; 0-10 V + volt free relay
  • Highly selective, Infra red sensor. Not affected by other gases found in offices or laboratories
  • No false alarms due to other gases
  • 1 alarm relay (volt free)
  • 1 x 4-20 mA or 0-20 mA or 0-10 V or 0-5 V o/p
  • 24 VDC operation
  • Flush wall mounted housing. To fit in with office environment
  • Easy to install
  • Calibration required every 3 years with 6 monthly functional tests
  • Australian Factory certificate of Calibration

Laboratory and Classroom Monitoring

When gas is piped into rooms for experimental purposes such as CO2, CO, or Natural Gas .The Gas Detection Australia range of sensors can be used to detect any leaks that may present a danger to health or explosion.

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?

  • All these gases are toxic at relatively low levels. Prolonged exposure to these gases is hazardous and results in serious health risks. GDA sensors can detect these gases at very low levels, in order to prevent this hazard becoming a danger to life.
  • Air conditioning systems and chillers that are leaking their refrigerant gases are not performing to maximum efficiency. The major use of refrigerant gases is in the re charging of these systems. If leaks are detected early the problem can be alleviated much quicker, saving costs on replacement gas, co maintenance and protecting the environment.
  • Gas detection at low levels (part per million) will give an early warning of leakage, therefore safeguarding life and maintaining the efficiency of the plant.

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.

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.
