Cut car park energy consumption in half with gas detection

The energy savings made by installing gas monitoring systems in underground and multi-storey car parks can save operators thousands of dollars and reduce their carbon footprint.

Austech installed a Carbon Monoxide (CO) gas monitoring system in an underground multi-storey car park in Sydney.

Designed in accordance with AS1668.1 the installation of CO gas monitoring means fans are not required to run 24/7 instead they can be automatically switched on and run only when needed. Since installation, this system has reduced energy consumption of the car park ventilation fans by more than 50%.

The system comprised of 34 Austech CO gas sensors and a rack mounted controller connected to the fans Variable Speed Drives. As part of a recent system upgrade, a supervisory control and data acquisition (SCADA) system was supplied. The system provides real time remote view of the gas values on the monitor in the control room and also provides data logging functionality. The system is expandable and easily configurable for future growth.

Austech’s CO gas detectors are affordable, robust devices specifically designed for use in car park systems.

Gas detection in testing environments

A national animal health research facility engaged Austech to assist them to investigate and test the concentration levels of CO2 gas in a livestock testing environment.

Carbon Dioxide (CO2) gas is registered in Australia for destruction of commercial poultry during an emergency disease incident, such as the highly pathogenic Avian Influenza.

A testing environment complete with CO2 gas sensors and logging panel was constructed in an empty shed, without chickens, with additional safety measures in place. The objective of Austech’s involvement was to monitor the concentration of CO2 gas in various sections of the shed when flooded by CO2 gas. The results from the test were used to validate the in-shed destruction of commercial poultry using CO2 gas during an emergency disease incident.

Equipment supplied:
Austech Instruments provided the gas detection equipment and the staff to set-up the equipment on site, run the data loggers during the CO2 gas flooding tests and download the data after each test. Additionally a written report of the results was provided to the research team.

The system consisted of four high range CO2 gas sensors and a portable data logger. The gas sensors were relocated in the poultry shed where a number of tests were undertaken and logged.

The CO2 gas sensors were specially modified by Austech to be 0-100% volume; in comparison to typical CO2 gas sensors which might only read to 5% volume.

Outcome:
The sensors performed reliably and accurately despite the rapid changes and subzero temperatures (-20°C) they were subjected to. Austech provided a full analysis and report to the client in regards to the CO2 gas measured throughout the test, allowing the client to draw conclusions regarding the use of the gas.

Austech’s ability to provide a proven consultancy service was a key factor in being chosen by the client to undertake the trial.

Austech signs on as MSA channel partner

This new partnership enables greater access to the latest technologies for safety instrumentation and strengthens Austech's ability to provide high tech solutions for various applications.

In addition to our own Australian designed, engineered and manufactured sensor technologies, Austech's channel partner arrangement will allow for distribution of a range of MSA fixed gas and flame detection instruments and controllers plus portable gas detection instruments and calibration systems such as:

  • Photo Acoustic Infra-red (PIR) – Developed for measuring toxicity levels in various hydrocarbons and other toxic gases including most refrigerants in PPB, PPM and %Volume ranges. This is achieved by utilising a unique combination of Infra-red and acoustic technologies to produce a very stable and accurate result that is not interfered by temperature and humidity. 
  • Ultrasonic or Acoustic (UGLD) – Originally designed for outdoor use with methane in the global LNG industry and adapted to other high pressure hydrocarbon gases like propane & hydrogen, the UGLD device can also be used for pressurised infrastructure of CO2, some refrigerants and steam. The UGLD 'listens for a leak' using a very sensitive microphone which is able to detect a leak as small as a pin hole. The UGLD does not rely on diffusion and is not affected by dilution, wind or background ultrasonics.
  • Open Path Infra-red Absorption (OPIR) – The Open Path IR is dual range and measures in %LEL-metre and PPM-metre simultaneously. The technology principle is the same as point or short path detection, will measure up to distances of 150 metres, is available for Methane and Propane applications and comes with digital alignment and multiple outputs features.
  • IR Gas Imaging - Designed for detecting large flammable or toxic gas plumes across a very wide area, detection sensitivity is up to 2000 metres within a 12 degree view angle or wider view with reduced distance. Up to four gases can be monitored simultaneously when connected to a computer with images and data from the detector processed to give a graphical visualisation of gas plumes and its dispersion path. Data quantifies the concentration of individual gas so thresholds can be set for alarming. Other features include location identification and the ability to deselect specific areas that could contain sources of false alarm.
  • Flame Detection - Most flame detectors identify flames by so-called optical methods like ultraviolet (UV) and infrared (IR) spectroscopy. Flames are generally fuelled by hydrocarbons, which, when supplied with oxygen and an ignition source, produce heat, carbon dioxide and other products of combustion. The reaction is characterised by the emission of visible UV and IR radiation. Flame detectors are designed to detect the absorption of light at specific wavelengths, allowing them to discriminate between real flames and false alarms. The MSA flame detectors are based on UV/IR or multi-spectrum IR (MSIR) technology. Both technologies are based on line-of-sight detection of the radiation emitted in the UV, visible and IR spectral bands by flames.
