Crowcon fixed gas detectors are point detectors that continuously monitor flammable, toxic, oxygen and refrigerant gases in industrial and commercial facilities. The range spans rugged infrared hydrocarbon detectors, intrinsically safe toxic detectors and SIL 2-certified transmitters for oil, gas and petrochemical plants. Akan Industrial and Automation supplies Crowcon detectors in Türkiye and provides system engineering, installation and commissioning support.
What is a fixed gas detector?
A fixed gas detector is permanently installed at a potential leak source or in an occupied area. It gives early warning of hazardous gas concentrations and sends a signal to a control panel, PLC, DCS or fire & gas system, which triggers alarms and protective actions. Crowcon is a part of Halma plc.
