Fire & Safety Control

Guardian of The Door.
Engineered for Safety.

A door closer is not just a mechanism; it is a critical component of building fire safety. Our Hydraulic Door Closers are designed to ensure doors latch securely every time, preventing the spread of smoke and fire.

From heavy-duty commercial entrances to standard residential doors, we utilize high-purity aluminum bodies and German hydraulic fluid to guarantee smooth, leak-free operation across millions of cycles.

Certified Compliance

Our closers meet stringent international standards, including UL/cUL (US) and CE/EN1154 (Europe). They are fire-rated for up to 3 hours, making them essential for commercial buildings, hospitals, and schools.

Precision Adjustability

Featuring independent valves for Sweep Speed, Latching Speed, and Backcheck (BC). This allows installers to customize the closing action to overcome air pressure and latch resistance perfectly.

Leak-Free Technology

Built with a high-strength aluminum alloy body and heat-treated steel piston. We use premium low-temperature hydraulic oil and double-sealing rings to prevent oil leakage, even in extreme cold climates.
