Pratley - Corrosion-resistant flameproof junction box

Pratley, manufacturer of innovative electrical termination products, has developed and launched its new product, the Flameproof Ex d Envirobox®. Which the company claims, is the world’s first polymeric, corrosion-resistant, direct-entry, flameproof junction box.

Flameproof equipment is designed to prevent internal ignition within a flammable atmosphere from transmitting outside the protective enclosure. However, traditional direct-entry flameproof junction boxes made from steel, cast iron or aluminium materials can be prone to corrosion over time when used in very harsh environments, where special attention needs to be given not just to the overall climatic conditions of the area where the enclosures are installed, but also to the material and design of the equipment.

Pratley’s new Flameproof Ex d Envirobox® junction box, made from a specially formulated, robust engineering polymer, has been designed to withstand these severe environmental conditions, thereby making it ideal for use in areas with a high risk of corrosion.

“The need for a lightweight and corrosion-resistant flameproof junction box is evident with the current, ever-changing mining environment. Over a decade’s worth of research and development went into the design and development of this junction box.” says Sven Breedt, Pratleys Electrical Research & Development Manager.
