Simplifying Hazardous Location Fire Suppression Systems

The Explosion Proof Actuator with Supervision is UL HazLoc, ATEX, and IECEx certified and acts as its own enclosure, eliminating the need for additional components.

Customer Problem

Fire suppression systems designed for hazardous locations are typically comprised of an actuating device that opens the discharge valve on the extinguishing agent cylinder, tubing to route discharge pressure (a source of potential leak points), and an enclosure to prevent accidental ignition of any flammable substances in the atmosphere. TLX had received numerous inquiries about a solution that would satisfy hazardous location requirements, be easier to install, and be less complex than existing systems.

The TLX Solution

TLX’s team decided to develop a top-mounted linear actuator that acted as its own enclosure. The top-mounted design means the Explosion Proof Actuator with Supervision does not act as a pressure vessel on the discharge valve, reducing the number of potential leak points in the system. Additionally, all potential flame paths are specifically designed to prevent flame egress in the event a spark were to ignite any gas found within the actuator.
