Sewage Treatment Plant Monitoring

The presence of Hydrogen Sulphide  can be detected by using the Gas Detection Australia GDA 2529 gas sensor to detect leaks of Hydrogen Sulphide  and evoke deodorisation plant. The SI-100C gas sensor can be used to monitor for leaks of LEL levels of methane gas. In digester applications Carbon dioxide can be detected using the GDA 4350  

Designed, Manufactured and Supported in Australia.

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.

Car Park Gas Monitoring Systems

The Gas Detection Australia car park gas detection system comprises of 1 up to 16 GDA 2525 carbon monoxide car park gas detectors per zone or level. The car park gas concentration signals are sent from the car park gas detector and the highest level from all the car park gas detectors are displayed locally on the control unit.  The latest regulations (AS1668.2-2012) call for variable extraction control and minimum flow rates. Gas Detection Australia car park system's allows variable-speed drive (VSD) control  that will meet this requirement of the australian car park gas detection standards. The car park carbon monoxide sensors (GDA 2525) are designed to be unobtrusive, simple to install and calibrate. All systems manufactured by Gas Detection Australia are built, programed and calibrated in our factory prior to delivery and will only require wiring and connecting .

Battery Room Monitoring

The SI-100C and a range of associated Gas Detection Australia controllers can be used in battery room gas detection  to detect hydrogen in battery rooms and sound alarms. The battery room gas detection systems comprise of a hydrogen gas sensor SI-100C and a gas sensor control unit. The Gas Detection Australia control unit  GDA 4020 or GDA 4011 is situated external to the battery room to display the gas concentrations and the alarm status. The battery room gas detection system can then be interfaced to extraction fans, sounders or other apparatus. For smaller battery charging rooms the standalone GDA 40126 can provide an integrated sensor and controller with outputs to drive extraction fans and sounders.

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.

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.

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.
