Product Datasheet


Glass reinforced polyester enclosures are used at chemical and petrochemical factories, on offshore platforms, oilprocessing plants and at other branches with potential availability of hazardous atmosphere (gas and combustible dust).

A wide range of models is intended for installation of electrical components and automation equipment, could be mounted indoor or outdoor in explosion hazardous zones, where explosive environment occurrence is possible.

Enclosures consist of a case and a lid fixed with captive loosing resistant screws. Enclosures are made of polyester reinforced with fiberglass, providing maximum protection from highly corrosive agents.

Graphite black color gives the maximum protection from UV radiation. Chemical composition of enclosure material eliminates any risks from sources of ignition by the means of statically induced sparking resistance. Enclosure sealing system has the shape of labyrinth, where silicone sealing is protected from environmental factors impact. Due to this quality, enclosures have a high ingress protection performance — IP66.

Inside enclosures there following electrical components could be installed: mounting panel, DIN-rails with terminals, earthing busbar and others. On the sides of boxes there could be installed explosion proof cable glands for different cable types, couplings, plugs, valves, earthing tags, etc.

In SST Group of Companies these enclosure types are used for the production of explosion proof equipment with “Equipment protection by increased safety” — “е” level; “Equipment dust ignition protection” — “t” level.
