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.

Our Process

Step 1 / Initial Review

Our engineering team works directly with you to determine the viability of your program and identify the best solution based on your specifications.

Step 2 / Quote

Quotes include all costs related to your project - tooling, prototype, piece part, production and project specific costs.

Step 3 / Design Review & Prototypes

Our engineering team reviews the design with you and makes any adjustments needed. Prototypes are built according to design specifications for testing.

Step 4 / Testing

Prototypes are tested according to your specifications, with all relevant test data provided to you for evaluation.

Step 5 / APQP

DFMEA’s, PFMEA’s, control plans and process flow diagrams are started to drive the product intent design.

Step 6 / Pre-Production

Working drawings are developed for production. A second prototype build and a set of production parts are made from tooling and thoroughly tested.

Step 7 / PPAP/Production

The final design along with the PPAP (Production Part Approval Process) is developed and the new product enters production.

Step 8 / Ongoing Improvements

Our team collaborates with you to continue making improvements to the product to best meet your needs, increasing efficiency and reducing cost.
