Application Scenarios
High-Traffic Public & Healthcare Building Installations
DC059DA UL‑listed delay‑action fire‑rated hydraulic door closer is engineered for heavy‑weight wooden fire doors in hospitals, schools and retail premises. Adjustable EN1‑EN6 power covers 20‑150kg doors with maximum width up to 1500mm. The 3‑15 second adjustable delay timer allows users extra time to pass through before automatic closing. Built‑in back‑check buffer prevents door slamming hard against wall or frame. UL10C 3‑hour fire rating meets North American fire code requirements for commercial fire door assemblies.
Heavy Wooden Fire Door New‑Build & Retrofit
This American style overhead hydraulic door closer uses imported FUCHS hydraulic oil and reliable leak‑proof sealing components, tested to 2,000,000 cycles. It works reliably for heavy wooden, metal, steel and fire‑rated interior and exterior door sets in new construction and renovation projects. Non‑handed universal mounting reduces inventory SKUs for large building projects.
