Commercial Hydraulic Door Closers Overview | BLOSSOM CHEER

Engineered for heavy-traffic corridors and fire exits, our hydraulic closers combine cast iron bodies, all-weather fluid, and multi-valve controls for smooth closing and ADA compliance.

Key Benefits of Commercial Hydraulic Door Closers | BLOSSOM CHEER

2,000,000-Cycle Heavy-Duty Endurance with Zero Leakage

High-strength cast iron housings and heat-treated rack-and-pinions endure 2,000,000 cycles, eliminating oil leakages in busy hubs.

All-Weather Fluid Preventing Speed Drift from -40°C to +60°C

Synthetic thermodynamic hydraulic oil maintains stable viscosity, preventing door slamming in summer and latch failures in winter.

Adjustable Power Sizes 1-6 for Barrier-Free ADA Compliance

Adjustable spring power lowers manual opening resistance below 15N, fulfilling barrier-free codes for healthcare and senior living.

Dual-Valve Regulation with Backcheck Protecting Wall Envelopes

Independent sweep, latch, and backcheck valves provide hydraulic cushioning, preventing door damage during sudden violent gusts.
