Cryogenic Rooms-Oxygen Depletion Gas Detection

Cryogenic freezing using liquid  Nitrogen poses a problem of oxygen depletion. The GDA 2528 oxygen gas detector / gas sensor offers a cost effective method of detection and low cost of maintenance. For standalone cyro-storage chambers housed in laboratories , the storage area can be monitored for oxygen depletion by the standalone GD40125 system.

Cellar-Carbon Dioxide Gas Detection

The ACGS-01 uses the latest patented laser source technology to provide reliable accurate and cost effective solutions for Carbon Dioxide gas detection in cellar gas detection applications. The Carbon dioxide cellar gas detection system  ACGS-01 comprises of a remote  carbon dioxide gas detector / gas sensor, an external  control unit + power supply (to view the gas levels and alarms before entry ) and a audio visual sounder/ flasher that  will activate on alarm. Gas Detection Australia offer a range of solutions to meet individual site requirements for carbon dioxide  cellar gas detection systems  and oxygen  cellar gas detection  when using nitrogen for  pre-mix drinks

MEETS THE REQUIREMENTS OF AS5034-2005.

Ambient Air Monitoring-Carbon Dioxide Gas Monitoring

A reliable low cost sensor to monitor the CO2 levels allowing an interface to a BMS system. The GDA 4350 series of flush wall mounted CO2 sensorsare designed fro internal use fitting into a Clipsal double gang switch box aperture 

Refrigerant Gas-Plant room, Office Gas Detection

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 gas leaks.. R22; R123; R134, R407; R410; Ammonia, Carbon Dioxide; Propane

MEETS THE REQUIREMENTS OF  AS 1677.1 & 2

DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA.

Laboratory and classrooms

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.

DESIGNED, MANUFACTURED AND SUPPORTED IN AUSTRALIA.

Food Processing - Gas Detection

Purgative gases such as Chlorine and Sulphur Dioxide present OHS requirements for workspace monitoring. Ammonia is often used as a refrigerant gas and can present OHS requirements for monitoring. Carbon Dioxide used in food packaging and stored on site needs to be monitored.

Air Conditioning- Gas Detection for Offices and Classrooms

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.
