MEDC SM87 | ATEX Beacons

Zone 1 & Zone 2 Hazardous Areas

Eaton MEDC SM87 LU1/LU3 are ATEX beacons specifically designed for use in potentially explosive atmospheres and harsh environmental conditions in ATEX & IECEx Zone 1 and Zone 2 hazardous areas.

The marine grade alloy or stainless steel enclosures of the ATEX beacons are suitable for use offshore or onshore, where lightweight combined with corrosion resistance and strength is required.

The hazardous area beacons can be painted to customer specification and fitted 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.

Stainless steel, one of the most durable materials available on the market, is both hard wearing and corrosion resistant, increasing the life of products in harsh environments and therefore reducing maintenance costs.

Contact Thorne & Derrick for customer service, competitive quotations and availability from stock for the MEDC range of sounders, including MEDC SM87 LU1/LU3, for safe use in hazardous areas with explosive atmospheres.
