Overview

The Ningbo Dimon Commercial Heavy-Duty Hydraulic Door Closer is an industrial-grade door control engineered for high-traffic exterior entrances, fire-rated assemblies, commercial storefronts, and institutional facilities. Tested to over 1,000,000 operating cycles, this cast aluminum closer features fully adjustable spring power from Size 1 to Size 6, reliably managing door weights up to 150 kg (330 lbs). With independent precision valve regulations for sweep speed, latching speed, and hydraulic backcheck (BC), it ensures smooth, controlled, and code-compliant closing action in demanding commercial environments.

Key Features

• Adjustable Spring Power (Size 1–6): Field-adjustable closing force meets barrier-free accessibility needs or handles heavy exterior wind loads for doors up to 150 kg (330 lbs).
• 1,000,000 Cycle Life Tested: Precision heat-treated rack-and-pinion transmission inside a high-strength cast alloy body delivers proven Grade 1 commercial durability.
• Independent Multi-Valve Hydraulic Controls:
  • Sweep Speed Valve: Regulates smooth door closing from maximum opening down to approximately 15°.
  • Latch Speed Valve: Controls the final 15° to ensure positive latch engagement without forceful slamming.
  • Hydraulic Backcheck (BC): Cushions the door against sudden wind gusts or aggressive openings to protect walls and hardware.
• Universal Tri-Pack Installation: Includes hardware for Regular Arm, Top Jamb, and Parallel Arm mounting, fully non-handed for left- or right-hand swinging doors.
• Full Architectural Cover: Heavy-duty molded cover conceals the closer body and mounting fasteners, providing sleek aesthetics and tamper resistance.
• All-Weather Hydraulic Fluid: High-grade temperature-stable fluid maintains consistent closing speeds across extreme hot and cold weather conditions (-30°C to 50°C).
