WERMA extends its range of Ex signal products

06 December 2012

Continuing development at WERMA has seen a new range of compact Ex certified beacons come to market, suitable for use in both Zones 1, 2, 21 and 22.

The new 729 series offers permanent, flashing and rotating LED beacons - also available with the enhanced EVS flash version - plus the 728 series with its classic xenon flash, and the 785 featuring a mechanical rotating mirror beacon. These new beacons are designed and manufactured to the highest standards, and are offered with a universal mounting bracket for ease of installation.

The chemical and petrochemical industries, as well as mining, have long been acutely sensitive to explosion risks. More recently, the food and beverage, metalworking and woodworking industries have become more focused on the problem, and in particular on those explosion risks arising from airborne dust.

WERMA has been developing products with combined approval for use in both gas and dust atmospheres for many years. The new ex-proof beacon series 729, 728 and 785 are also approved for use in zones 1, 2, 21 and 22, and are capable of operating at temperatures as low as -50°C, significantly extending their application possibilities. 

There is more to the development and production of a completely new explosion-proof product series than meets the eye. Alongside the costly development and product approval process, the testing and assembly facilities required also entail significant investment. These are essential to guarantee the consistently high standard of quality customers have come to expect from WERMA.
