Car Park Gas Detection

Car park gas detection

Underground car park gas detection is commonly fitted for environmental protection and energy cost saving. If there is no exhaust gas pollution present, then ventilation rates can be reduced to save energy. The building regulations specify what is required to maintain safe conditions, specifically section F which highlights the gas detection. This is a very effective energy reduction solution, provided the air quality is correctly monitored with suitable gas detectors.

Why Choose IGD

IGD can help design effective systems utilising our extensive experience of these applications. We regularly supply systems for carbon monoxide monitoring (CO), Carbon Dioxide (CO2), Nitrogen Dioxide (NO2) and Flammable gases such as LPG detection (for enclosed car park applications). This is dependent upon the client’s requirements and vehicle profiles.

Car Park Gas Detection capability

Carbon Monoxide is always the primary detector in this application as it poses the biggest threat to life. Other gases must be considered. If the underground area is primarily a “goods delivery point”, then Nitrogen Dioxide should be included as this is produced from diesel fuelled delivery vehicles.

Similarly, in countries with higher densities of LPG, Ethanol or Hydrogen fuelled vehicles, flammable gas detectors may be included to counter heavier than air fuel leaks. These can form significant explosive atmospheres in underground areas where concentrations can quickly accumulate.

Our Ground-Breaking Solution:

Our latest addressable gas detector technology (2-Wire Addressable) offers the best possible installation savings; whilst giving enhanced performance and flexibility. IGD have modular solutions to suit all these applications using our 100 years+ of gas detection knowledge and industry leading technology.

2-Wire Addressable Systems:

Our 750 series detector nodes have 7 i/o points. This allows you to have local distributed control, allowing you to control:

  • jet fans.
  • illuminated signs.
  • audible/visual alarms.
  • Other gas detectors.
  • any device with a 4-20mA output or Digital output/input

All of the above from the nearest available detector node (see diagram below). In addition to this, the 750 series controllers are available as a din rail mount version. This allows you to incorporate the ‘brains of the unit’ into the overall ventilation control cabinet. Our 2-Wire Addressable Systems have seen cost savings of 70-80% compared to current gas detection systems on the market.

2-Wire addressable also features a wealth of android apps, allowing your service teams to quickly and effectively service an IGD system. Furthermore, our CO sensors now have a typical 10-year lifetime; giving your clients peace of mind and reduced on-going costs, compared to other CO sensors on the market.

If you are interested in utilising our ground breaking technology, full training on install, service and commissioning, or have a project and would like a comparison quote, call IGD on 0161 483 1415 or email: sales@internationalgasdetectors.com

Case Study:

IGD recently upgraded an analogue car park gas detection system to our addressable systems, as the client needed to cut costs whilst adding flexibility to their systems. You can read this case study here and see how IGD’s addressable gas detection system not only gave the client the flexibility they needed; but also how our addressable system reduced the installation cost by 70%.
