- •Specifiers seeking an EN1154/CE certified hydraulic door closer with adjustable power and back-check.
✕ Who Should Avoid
- •Applications where a hold-open function is legally or operationally required (this model does not have it).
- •Installations where a delayed action closing feature is essential for accessibility or logistical reasons.
- •Projects with extremely lightweight doors (below 40kg) where lower power sizes are more appropriate.
- •Environments requiring specific extreme temperature operating ranges beyond standard internal conditions, as these specifications are not provided.
Product Overview
The Godrej Fire Rated Hydraulic Door Closer, part of the distinguished Fire Rated Series (2018-2026), is an essential component for maintaining fire compartmentation and controlled access in commercial and public sector facilities. Manufactured in India from high-grade Aluminium Alloy or Cast Alloy with a silver finish, this surface-mounted, non-handed unit is designed for versatile application on wood, metal, and fire doors. It features independently adjustable closing and latching speeds, allowing for precise control over the door's final movement and secure engagement with the frame. The selectable power size range from 2 to 5 (EN1154 compliant) ensures optimal performance across a wide spectrum of door weights and widths, up to approximately 1400mm. With integrated back-check, the closer offers critical protection against forceful opening, preventing damage to the door, frame, and surrounding structures. Its robust hydraulic mechanism is engineered for reliability, evidenced by a cycle test rating exceeding 500,000, underscoring its suitability for high-traffic environments.

Engineering Analysis
The Godrej Fire Rated Hydraulic Door Closer embodies advanced hydraulic engineering principles critical for compliant and reliable door control.
Hydraulic Mechanics and Precision Control: At its core, the closer utilizes a sealed hydraulic system, featuring precision-machined adjustable valves. These valves modulate the flow of hydraulic fluid, directly influencing the speed at which the door closes through two independent stages: the main closing speed and the final latching speed. This dual-valve adjustment allows installers to fine-tune door movement for specific environmental conditions and user requirements, ensuring controlled, quiet closure without slamming, and consistent latch engagement. The integrated hydraulic back-check mechanism provides a cushioned stop against rapid opening beyond a certain angle (typically 70-85 degrees), protecting the door, frame, and adjacent walls from impact damage, a crucial feature in high-traffic or wind-prone areas. The robust Aluminium Alloy body and heavy-duty arm assembly are engineered to withstand the continuous forces exerted during door operation, contributing to the system's longevity and structural integrity.
EN1154 Compliance and Fire Safety Integration: This closer's certification to EN1154/CE standards signifies rigorous testing and adherence to European benchmarks for durability, efficiency, and safety for controlled door closing devices. This includes specific requirements for closing force consistency, operational temperature range, and endurance. The selectable power size range (EN size 2-5) directly correlates with the EN1154 standard, allowing for precise force adjustment to manage doors within the 40-120kg weight range and up to 1400mm width, ensuring optimal closing efficiency. Critically, its "Fire Rated" status, alongside EN1154/CE certification, confirms its suitability for installation on fire-rated doors. In the event of a fire, the closer ensures the automatic and positive closure of fire doors, maintaining the integrity of fire compartmentation and preventing the spread of smoke and flames, a vital function for occupant safety and building protection. The 500,000+ cycle test rating exceeds standard requirements, guaranteeing long-term operational reliability even under demanding fire safety protocols.
Durability and Sustained Performance: The construction using Aluminium Alloy for the body and a heavy-duty arm not only contributes to the closer's overall robustness but also its ability to maintain consistent performance over extended periods. The hydraulic seal type minimizes fluid leakage, preserving the internal pressure and the effectiveness of the damping mechanisms. This careful material selection, combined with rigorous manufacturing, underpins the 3-year manufacturer's warranty and the high cycle test rating, affirming its position as a durable solution for demanding commercial environments where consistent door control and fire safety are paramount.
