Fixed Point Gas Detection Solutions


Gas detection for commercial and industrial applications often requires a bespoke system to ensure the installation protects personnel against specific toxic, flammable and asphyxiate gas levels.

Shawcity provides a flexible range of wireless or hard wired fixed-point detection systems from leading manufacturers such as Honeywell, GDS, Crowcon, RAE Systems and GFG. With such a wide choice of solutions, we can design, install, commission and service standard and bespoke systems to suit every environment and even fabricate specialist equipment. Systems are available in flameproof, intrinsically safe or safe area formats and housing options include weather caps for extreme environments.

Gas detection heads are installed in hazardous areas and transmit data to control panels, which are usually located in safe areas but can be installed in IS/ATEX rated zones. They handle Gas Detection Head inputs (up to 64) and can be networked to a central point so that multiple control panels or systems can be monitored remotely. Locally, the control panel has relays and signal output to interface with Building Management Systems or Programme Logic Controllers as well as actuate equipment (e.g. shut-off valves) and alarms.

A wide range of target gas options are available including toxic, flammable, oxygen and volatile organic compounds. Common gases include: Ammonia, Chlorine, Ozone, Hydrogen Sulphide, Hydrogen Cyanide, Sulphur Dioxide, Phosphine, Nitric Oxide, Nitrogen Dioxide, Carbon Monoxide, Volatile Organic Compounds (VOCs), Carbon Dioxide, Ethylene Oxide, Chlorine Dioxide, Methane, Pentane, Propane, Hydrogen, Ethanol, Flammable Gases, Methanol and Butane.

We also offer thermal conductivity sensors to monitor volume concentrations of gases and poison-resistant pellistors for flammable detection including hydrocarbons, hydrogen, ammonia, jet fuel, leaded petrol and vapours containing halogens. However these lists are not extensive and further options are available, contact us for more information or to discuss your requirements.
