The unit utilizes a heavy-duty rack-and-pinion hydraulic engine supported by high-tensile internal springs. It is rated for door panel weights up to 85 kg and maximum door widths up to 1100 mm. To house the internal closer body safely without compromising structural integrity, the door leaf requires a minimum thickness of 45 mm.
It features double-valve adjustment for independent control of both closing speed (180° to 15°) and final latching action (15° to 0°). Thermostable hydraulic fluid prevents speed changes during extreme summer heat or winter cold, while non-removable adjustment valves and vacuum impregnation guarantee leak-proof operation. The closer supports up to 180° maximum opening angle (or 90° hold-open depending on track configuration) and is endurance-tested for 100,000 open/close cycles.
The Godrej Concealed Hydraulic Door Closer (85 kg Variant) is a heavy-duty concealed closing system designed for high-traffic, solid-core doors where high load capacity is required without visible surface hardware.
Product Overview & Description

It combines a cast-aluminum housing with a hardened alloy-steel rack-and-pinion hydraulic assembly to support large architectural doors up to 85 kg. When the door is closed, the main body and slide track are hidden from view.
