Protects from high temperature fires

A new range of cabinets to protect
critical process equipment in
hazardous areas against very high
temperature fires has been launched
by Intertec. The cabinets ensure that
equipment such as emergency
shutdown valves remain operational
by keeping them below 60°C for
periods of up to 90 minutes in the
event of a hydrocarbon-based fire, to
allow time for controlled shutdown.

The new 90-minute protection
capability – which Intertec believes
to be a first in this sector of the
industry – has been tested against
the ANSI/UL 1709 standard by the
test body MPA Dresden.

The extended protection time
helps plant operators to continue
remotely controlling critical valves to
ensure the process cannot feed the
flames with flammable materials, or
that vessels do not burst from overpressurisation.
