Intertec’s 2016 “Ex p” cabinets simplify instrumentation deployment
By Renée Francoeur
March 28, 2016 – Outdoor enclosure specialist Intertec has launched a new range of explosion-proof cabinets to protect field instrumentation operating in hazardous areas. Available in a 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. Intertec says they are ideal for housing forward-placed analyzer equipment in industrial process facilities such as petrochemical/oil refineries and fertilizer production/storage plants, and also provide the possibility to install non-Ex rated analyzers and instrumentation inside Zone 1 or 2 classified environments.
The pressurized explosion-proof (Ex p) cabinets are constructed from GRP (glass reinforced polyester) composite materials. These materials are highly resistant to corrosion, Intertec claims, and have a similar strength to stainless steel, but are about 75% lighter.
Single-piece panels of GRP composite can be produced as large as 6×12 metres.
The pressurized 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.
