Godrej Surface-Mounted Hydraulic Door Closer with Adjustable Backcheck and EN1154/CE Certification

The Godrej Hydraulic Closer with Adjustable Backcheck embodies sophisticated hydraulic engineering, meticulously designed to deliver consistent and controlled door movement. At its core, the aluminium alloy body houses a high-grade hydraulic seal system, which is fundamental to its enduring 500,000+ cycle test rating. The internal hydraulic fluid, precisely calibrated, allows for fine-tuning of door dynamics through a series of adjustable valves. The 'Adjustable Closing Speed' valve governs the door's velocity from its fully open position down to approximately 10-15 degrees from closure. This is critical for managing pedestrian traffic flow, ensuring smooth operation without abrupt slams. Complementing this, the 'Adjustable Latching Speed' valve controls the final few degrees of travel, ensuring the door confidently engages with the latch without excessive force, thereby protecting both the door frame and the lockset. A standout feature is the 'Adjustable Backcheck'. This hydraulic cushioning mechanism engages when the door is opened beyond a pre-set angle (typically around 70-85 degrees), providing resistance to prevent the door from slamming into an adjacent wall or stop. The adjustability of this feature allows engineers to calibrate the resistance level to specific application requirements, crucial for high-traffic areas or environments prone to strong drafts. Crucially, this closer's compliance with EN1154 and CE certifications is not merely a label; it signifies rigorous testing against European standards for performance, durability, and safety for controlled door closing devices. The 'Fire Rated' capability further underscores its suitability for critical egress routes, ensuring the integrity of fire compartmentation by reliably closing fire doors even in emergency scenarios. The selectable power sizes (EN2-4 and EN2-6) are achieved by manipulating the spring tension within the hydraulic mechanism, offering unparalleled adaptability to doors ranging from 40kg to 120kg, thereby optimizing energy consumption and operational effectiveness for a wide array of wood and metal door specifications.
