Fixed point gas detection solutions

Posted on Friday 1 January 2010

Shawcity provides a flexible range of wireless or hard wired fixed-point systems from manufacturers including Honeywell, GDS, Crowcon, RAE Systems and GFG to protect personnel against specific toxic, flammable and asphyxiate gas levels.

With so many solutions to hand, the company can design, install, commission and service standard and bespoke systems for any environment, available in flameproof, intrinsically safe or safe area formats.

Gas detection heads can be networked so that multiple control panels or systems can be monitored remotely. Control panels have relays and signal output to interface with Building Management Systems or Programme Logic Controllers and actuate equipment (e.g. shut-off valves) and alarms.

A wide range of target gases includes 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.

Shawcity also offers thermal conductivity sensors to monitor volume concentrations of gases and poison-resistant pellistors for hydrocarbons, hydrogen, ammonia, jet fuel, leaded petrol and vapours containing halogens.
