Intertec explosion-proof cabinets

Wednesday, 04 May, 2016 | Supplied by: Intertec

Outdoor enclosure specialist Intertec has launched a range of explosion-proof cabinets to protect field instrumentation operating in hazardous areas. Available in a diverse range of standard sizes, as well as in custom shapes up to walk-in shelter size, the cabinets are certified for use in Zone 1 and Zone 2 hazardous areas. They are suitable for housing forward-placed analyser equipment in industrial process facilities, such as petrochemical/oil refineries and fertiliser production/storage plants, and also provide the possibility to install non-Ex rated analysers and instrumentation inside Zone 1 or 2 classified environments.

Intertec’s pressurised explosion proof (Ex p) cabinets are constructed from GRP (glass-reinforced polyester) composite materials. The materials are highly resistant to corrosion and have a similar strength to stainless steel but are about 75% lighter. They are especially suitable when robustness and rigidity need to be combined with low mass — such as on offshore platforms.

GRP composite materials also have a much higher thermal resistance than metal. This simplifies the construction of cabinets that provide good insulation, reducing the energy required to heat or cool the equipment. It also makes it easier to build cabinets without any thermally conductive links between their exterior and interior surfaces, thereby avoiding creating cold spots which can lead to problems with condensation.

GRP composite panels can be chemically bonded to create tight sealing that prevents the ingress of hazardous gas and reduces the consumption of air, which is used to create the slight positive overpressure needed for Ex p protection.
