The GDA 4080 Gas Detection Controller is designed to be to take up to eight sensor inputs and display the gas readings of the individual sensors. The multi-colour display will indicate the alarm status, levels and faults.

Designed, manufactured and supported locally in Australia.

There are 8 fully user configurable relays; and an additional fault relay. The GDA 4080 has a compliant MODBUS interface allowing all of the controller’s information to be read into a BMS systems. The system has an independent two wire comms system to drive remote mimic panels which indicate the current gas levels in their associated area. It is housed in an enclosure with a swing door making cable access and servicing easy.

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?

  • 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, R410a, R514a, R1234yf and many others.

Hazardous Areas (IEC Ex Certified)

IEC Ex approved gas detectors and sensors for use in Zone 1 and Zone 2 areas within Australia for both Toxic and Flammable gases.

Hazardous Areas are areas in which an explosive gas atmosphere is or may be expected to be present, in quantities such as to require special precautions for the construction installation and use of equipment construction, installation and use of equipment. Hazardous areas are classified into 3 zones based upon the frequency of the occurrence and duration of an explosive gas atmosphere, as follows:

  • Zone 0 - Area in which an explosive gas atmosphere is present continuously or for long periods or frequently.
  • Zone 1 - Area in which an explosive gas atmosphere is in which an explosive gas atmosphere is likely to occur in normal likely to occur in normal operation occasionally.
  • Zone 2 - Area in which an explosive gas atmosphere is not likely to occur in normal operation but, if it does occur, will persist will persist for a short period for a short period only.
  • Non hazardous area (safe area) - A non hazardous area is an area in which an explosive atmosphere is not expected to be present.
