supports trend to move control and instrumentation closer to the process

Intertec has launched a unique inspection door for outdoor equipment protection enclosures. The new GRP Inspection Door comes with a window frame made entirely from GRP (glass reinforced polyester) - a material offering a very high degree of protection against corrosion combined with excellent thermal insulation.

The design offers a more durable alternative to the conventional aluminium or stainless steel window frames commonly used for field equipment in harsh environments, helping to extend the lifecycles of business-critical process control and instrumentation equipment. Doors are available with either IP54 or IP65 ingress protection ratings.

Intertec's GRP inspection doors are ideal for enclosures and cabinets containing control and instrumentation equipment fitted with user interfaces, indicators and displays. This embraces a broad range of commonly-used field equipment including process transmitters and PLCs. A lot of this type of equipment is increasingly being located deeper inside the processing areas of a plant, where environments can expose the equipment to harsh and corrosive atmospheres.

GRP is an inherently inert material that is virtually immune to corrosion and atmospheric pollutants. It does not rust or degrade in any meaningful way, and is resistant to a wide range of chemicals. The GRP sheet material used in the door's construction also provides excellent thermal insulation for field equipment requiring heating or cooling. GRP's thermal conductivity is around 5,000 times less than aluminium and 1,000 times less than steel - alternative materials widely used for window frames in this application. This helps to eliminate 'thermal short cuts' between interior and exterior, which can lead to cold spots and condensation problems.
