ATEX Fire & Heat Detectors
Zone 1 & Zone 2
Eaton MEDC HD1 are ATEX heat detectors that have been designed for use in ATEX & IECEx Zone 1 and Zone 2 hazardous areas. These hazardous are heat detectors are suitable for fire alarm and/or suppression systems in offshore and onshore applications including paint spray booths, flammable material stores, turbine rooms, extract ductwork and other hazardous areas throughout the oil & gas, petrochemical and process industries.
Comprising a Fenwal rate-compensated detector with all-stainless steel external construction, mounted to either a type SM87 marine grade alloy enclosure (Ex d version) or JB10 corrosion-free GRP enclosure (Ex ia, Ex em/UL versions). The contact in the ATEX heat detector closes at alarm temperature.
