Passive fire protection cabinets for process plant protection applications are usually only required to provide 30 minutes of protection. In the event of a hydrocarbon-based fire, however, Intertec’s new cabinets ensure equipment such as emergency shutdown valves remain operational by keeping them below 60°C for periods of up to 90 minutes, allowing time for controlled shutdown. The new 90 minute protection capability has been tested against the ANSI/UL 1709 standard by the test body MPA Dresden.

With the cabinets, there is also the ability to incorporate easy-access panels to simplify maintenance and inspection, because of the rigid structure provided by the composite construction materials.

Intertec’s cabinet designs for critical field equipment are based on a form of layered construction with GRP sheets ‘sandwiching’ insulating and fire resistant mineral wool materials.
