Intertec GRP inspection door

Intertec has announced an inspection door for outdoor equipment protection enclosures. The GRP Inspection Door comes with a window frame made entirely from GRP (glass-reinforced polyester) — a material offering a high degree of protection against corrosion combined with good 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 life cycle of business-critical process control and instrumentation equipment. Doors are available with either IP54 or IP65 ingress protection ratings.

The GRP inspection doors are suitable 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.

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 it is resistant to a wide range of chemicals. Its thermal conductivity is also around 5000 times less than aluminium and 1000 times less than steel. This helps to eliminate ‘thermal shortcuts’ between interior and exterior, which can lead to cold spots and condensation problems. In its basic form, these properties make GRP a suitable material for robust outdoor enclosures, allowing maintenance-free life cycles of 30 years and more.

Two variants of the GRP inspection door are available, with window frames measuring approximately 50 x 35 or 67 x 47 cm.
