MEDC TH12 Hazardous Area Beacons
MEDC TH12 | ATEX Beacons
Zone 1 & Zone 2 Hazardous Areas
MEDC TH12 are ATEX beacons that are able to rotate designed for use in potentially explosive atmospheres and harsh environmental conditions.
The hazardous area beacon enclosures are suitable for use offshore or onshore, where light weight combined with corrosion resistance is required, and can be ordered from Thorne & Derrick with MEDC call points for integration into fire detection systems in the explosive atmosphere industries.
The 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.
The Eaton MEDC ATEX beacons can be painted to customer specification and supplied with identification labels.
Contact Thorne & Derrick for customer service, competitive quotations and availability from stock for the MEDC range of sounders, including MEDC TH12, for safe use in hazardous areas with explosive atmospheres.
