Outdoor enclosure company Intertec has launched a new range of explosion proof cabinets to protect field instrumentation operating in hazardous areas. Available in a diverse range of standard sizes and custom shapes up to walk-in shelter size, the cabinets are certified for use in zone 1 and zone 2 hazardous areas. They are ideal for housing forward-placed analyser equipment in industrial process facilities such as petrochemical/oil refineries and fertilizer production/storage plants.
Intertec’s pressurised explosion proof (Ex p) cabinets are constructed from GRP composite materials that are anti-corrosive, offer excellent insulation, lightweight and possess steel-like strength as well as high thermal resistance than metal, thereby making them ideal for equipment containment and personnel shelter applications.
The pressurised cabinets are equipped with a control unit that regulates the flow of inert purging gas or compressed air, and then monitors the pressure inside the cabinet to ensure that it is maintained slightly above atmospheric pressure by automatically compensating for any leakage losses.
Each partially equipped enclosure is then tested by Intertec at one of its manufacturing plants, before being delivered to the system integrator for installation of the analyser instrumentation.
