AUMA fireproof actuators

 

Where highly flammable substances are part of a process, such as in the oil and gas industry, there still remains a fire hazard despite high safety standards. In the event of a fire the damage must be limited to a minimum. It is therefore necessary in these situations to influence the process, e.g. to cut off the supply of flammable substances.

 

This is only possible if fireproof equipment has been installed in the plant which will remain operative even under these extreme conditions.

 

AUMA fireproof actuators can, in case of fire, contribute a great deal to limiting the risks for people, the environment and the plant. The functionality, application possibilities, operation and user friendliness are comparable to the proven non-fireproof actuators.
