Fixed point gas detection solutions

31 October 2017

Gas detection often requires an installed fixed system to ensure personnel are protected against specific toxic, flammable and asphyxiate gas levels.

Shawcity provides a wide range of wireless or hard wired fixed-point detection systems from leading manufacturers such as Honeywell, GDS, Crowcon, RAE Systems and GFG. It can design, install, commission and service flexible systems to suit every environment in flameproof, intrinsically safe or safe area formats.

Gas detection heads are installed in hazardous areas and transmit to control panels which can have up to 64 Gas Detection Head inputs and 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 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. Options include: NH3, Cl, O3, H2S, HCN, SO2, PH3, NO, NO2, CO, VOCs, CO2, EO, ClO2, CH4, C5H12, C3H8, H2, C2H5OH, CH3OH, C4H10 and flammable gases.

Shawcity can also monitor volume concentrations of hydrocarbons, hydrogen, ammonia, jet fuel, leaded petrol and vapours containing halogens.
