Passive Fire Protection

General standard requirement

Protect parts 1093°C/2000°F during 30 minutes.

Result: After the test, the protected parts must to be operative and will keep their operational features.

Application types

SURFACE COATING: applied directly over all external surfaces of the parts which are going to be protected against fire. The coating is permanently fixed to the surfaces. This protection system allows the performance of any kind of maintenance operations.

MODULAR SYSTEM: The modular system consists of two parts which cover and protect the equipment. Both parts are adapted to the external shape of the equipment, reducing all the possible gaps. It also allows performing any kind of maintenance.
