A BEACON OF LIGHT
Cooper MEDC have designed and manufactured alarm, signal, control and communications equipment since 1975. The company has developed a range of products specifically designed for use in areas where harsh environmental conditions prevail and where there is a risk of explosion due to the presence of flammable atmospheres, both onshore and offshore

MEDC have pioneered the use of glass reinforced polyester (GRP) in explosion-proof products. The advantages of GRP products include a lower capital cost, combined with minimal maintenance and extended lifetime, thus lowering the cost of ownership.
The innovative use of GRP has now been extended to include a range of uncertified (safe area) equipment for use in harsh industrial and marine environments.
Explosion-proof products include manual call points, status lamps, beacons/strobes, sounders/horns, alarm bells, speakers, control units, control stations, control panels, junction boxes, terminal boxes, and distribution panels/boards.
Products are available in a range of certifications including ATEX, UL, CSA, GOST and Inmetro. A wide variety of these products are held in stock for dispatch within 24 hours of ordering. MEDC also offers a range of uncertified equipment for harsh industrial and marine environments and the ‘Next Two’ range of loudspeakers for safe areas/interiors.

Manual Call Points
These products are available in breakglass and pushbutton versions. These explosion-proof call points are available as intrinsically safe (Eexia), flameproof (EExd) versions. Many call point options are available including body colour, lift flaps and resistors.

Status Lamps
These versatile status lights are available with LED, Xenon, filament and fluorescent lights. Explosion-proof and uncertified versions are available.

Beacons & Strobes
These certified beacons are suitable for use where a lightweight product is required, with corrosion resistance and strength. Beacons are available in LED, Xenon, rotating, beacon/sounder combination, and steady beacon versions.

Sounders & Horns
The MEDC range of lightweight, flameproof sounders has been designed for the most hostile environments. Outputs of 103dB(A) to 118dB(A) at 1m are available. A new voice sounder has recently been launched; this unit offers up to 20 seconds of speech which can be recorded via an integral microphone or an input from an external source.
The unit incorporates a variable delay, allowing speech to be repeated at equal intervals of up to approximately 15 seconds.

Alarm Bells
The explosion-proof bell is manufactured from cast iron, and is available in DC and AC versions. The bell can be painted to the customer’s specification.

Loudspeakers
MEDC offer explosion-proof loudspeakers for use in potentially explosive gas & dust atmospheres. Using MEDC’s proprietorial GRP technology, a cost effective, robust, and corrosion-free solution to metal loudspeakers is available. With power ratings up to 25W, this range is suitable for PA and VA applications.
In addition, MEDC offer the ‘Next Two’ range of loudspeakers, for use in industrial, commercial and leisure applications. They are suitable for areas which do not require certification.

Control and Distribution Units Panels and Boards
This range of custom built control & distribution units can be used individually, or they can be combined to provide hazardous area systems for indoor or outdoor use. MEDC have a wide experience of providing complete control & distribution systems for use in potentially explosive atmospheres.

Control Stations
These control stations are suitable for use in all gas groups, including hydrogen. The rugged enclosures are manufactured from a UV stable, glass reinforced polyester. Cover fixing screws are stainless steel thus ensuring a corrosion-free product.

Junction Boxes
These GRP junction boxes have a robust design, coupled with corrosion-free GRP and a high ingress protection rating, ensuring a long life, low maintenance product.

Terminal Boxes
The comprehensive range of GRP terminal boxes offers a variety of enclosure sizes, terminals and cable entries.
