Intertec has developed an innovative ATEX-compliant HVAC system that provides a complete all-in-one climate control and personnel safety solution for walk-in style process analytical instrumentation shelters.
It is customisable and scaleable to suit a broad range of applications, and can be supplied fully integrated within the shelter or as an external standalone unit.
Designed specifically for hazardous area applications up to zone 1, the system delivers a steady flow of conditioned and filtered clean air to the shelter, maintaining it slightly above atmospheric pressure to prevent the ingress of dust or gas.
To help ensure measurement accuracy, sensitive equipment such as process analyzers and sample conditioning systems needs to be maintained at a constant temperature.
Nearly all explosion-proof air conditioning systems on the market are contained in metal enclosures, which are susceptible to corrosion.
Intertec's new HVAC system is unique in that its entire housing is constructed from the company's proprietary GRP (glass reinforced polyester) triple-layer composite material.
This comprises inner and outer layers of GRP enclosing a thermally insulating core; the wall thickness and core properties can be varied to suit the application and operating environment.
GRP is an excellent thermal insulator and is similar strength to stainless steel, but is about 75 per cent lighter.
