Material Composition & Performance

Scientific material selection ensures longevity:

  • Shell: 304 stainless steel or die-cast aluminum, resisting corrosion in coastal areas .

  • Internal Components: Quenched alloy steel gears (tensile strength ≥ 600MPa) and nitrided steel pistons, preventing oil leakage .

  • Hydraulic System: Aviation-grade condensate oil, maintaining stability at -40℃ to 50℃ .


Installation & Operation Guide

Standard installation (5-step process) requires only basic tools (drill, screwdriver, tape measure):

  1. Mark mounting positions on the door top and frame using the provided template .

  2. Secure the closer body to the door and the bracket to the frame with stainless steel screws.

  3. Connect the linkage rod, ensuring it’s parallel to the door when closed.

  4. Adjust closing speed: 5s from 90° to 20°, 2s from 20° to full close via hydraulic valves .

  5. Install the plastic oil-collecting cover to prevent contamination .
