MEDC DB1 are part of range of lightweight, flameproof ATEX sounders that have been designed with a high weatherproof rating to cope with the harsh environmental conditions found offshore and onshore in the oil, gas and petrochemical industries – in ATEX & IECEx Zone 1 and Zone 2 hazardous areas.
The new electronic circuitry of the MEDC DB1 allows the DB1P and DB1HP hazardous area sounders to be switched between two selectable tones by either reversing the supply polarity, or connecting a second voltage supply.
A variety of sounder tones are available for MEDC sounders.
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 our team for great customer service, competitive quotations and availability from stock for the MEDC range of sounders, including MEDC DB1, for safe use in hazardous areas with Explosive Atmospheres.
The MEDC DB1 hazardous area sounder is available in a choice of variants with Ex d and UL approvals.
The MEDC range of sounders and beacons from the Crouse Hinds series of Signalling & Alarms – a comprehensive range of Explosion Proof call points are also available with ATEX & IECEx certification and explosion protection to both Ex d (flameproof) and Ex ia (Intrinsically Safe) applications.
The following code is designed to help in selection of the correct Eaton hazardous area sounders with ATEX approval and certification. Build up the part number by inserting the code for each component into the appropriate box.
EATON MEDC
Eaton MEDC have developed ATEX products, including ATEX Beacons, designed for harsh and hazardous area conditions and where there is a risk of explosion due to the presence of flammable gas and dust atmospheres both onshore and offshore – since 1975 MEDC have been designers and manufacturers of alarm, signal, control and communications equipment.
Complete range of LV-HV Cable Joints, Terminations, Cleats & Glands are available to support installation of power, control and instrumentation cables up to 33kV – includes Cold Shrink for use in hazardous areas to provide electrical insulation and cable protection.
