Gas alarms are designed for monitoring of pre-explosive concentrations of sum of flammable gases in the air of working area of premises and open spaces.
Application:
01. On drilling and extractive platforms, in places of installations of processing equipment in process of oil and gas extraction and processing;
02. In reservoirs of oil and oil products storage.
03. At enterprises of chemical and metallurgy industry;
04. In paint and varnish industry, fertilizers and plastics production;
05. At enterprises of fuel-energy complex, oil-processing plants, heat electropower stations, boiler plants;
06. For application in the conditions of the Extreme North and the Arctic.
Type of gas alarms – fixed, automatic, single-channel.
Principle of operation – thermochemical.
Sampling diffusion or forced, due to excess pressure in sampling point.
