MEDC FB11 FL11 Hazardous Area Beacons
MEDC FB11 & FL11 | ATEX Beacons
Zone 1 & Zone 2 Hazardous Areas
MEDC FB11 & FL11 are ATEX beacons that have been designed for use in potentially explosive atmospheres and harsh environmental conditions in ATEX & IECEx Zone 1 and Zone 2 hazardous areas. The enclosures are suitable for use offshore or onshore, where light weight combined with corrosion resistance is required.
The hazardous area beacon housing is manufactured completely from a UV stable, glass reinforced polyester. Stainless steel screws and mounting bracket are available ensuring a totally corrosion free product.
ATEX beacons can be painted to customer specification and supplied with identification labels, and can be ordered from Thorne & Derrick with MEDC call points for integration into fire detection systems in the explosive atmosphere industries.
Contact Thorne & Derrick for customer service, competitive quotations and availability from stock for the MEDC range of sounders, including MEDC FB11 / FL11, for safe use in hazardous areas with explosive atmospheres.
