Mechanical Only Self Closing 

Waterson mechanical hinges are great for high-frequency use heavy doors. State-of-the-art heat treated carbide components and EN-certified springs ensure durability, effectiveness, and longevity. Due to durable and constant braking force, your heavy-duty commercial doors will close effectively at a controlled speed every time. You can let the door close on its own without any hand force to avoid accelerated closing speed. Ideal for hotel rooms, fire-rated doors, and arch-top openings, to name a few.

Hydraulic Hybrid Soft Close

On the other hand, if the quiet closing, breezy environment, and users pushing too hard are chief concerns then you may want to consider choosing the Waterson hydraulic hybrid self-closing hinges due to its oil-controlled dynamic braking. Also an effective closing component, particularly in breezy conditions, Waterson hydraulic hinges respond well sans leakage to sudden wind changes with exceptional quietness. Great for offices, rugged exterior environments as low as -32F, glass doors, and more.

Wind Resistance & Anti Slam: Mechanical vs. Hydraulic

Mechanical spring hinges offer self-closing functionality with speed control for interior and frequently used doors. However, these mechanical properties only allow for speed control within a constant speed zone. If the wind exceeds this setting, the door is prone to slamming shut.

On a positive note, the mechanical hinges are resilient against strong winds. They exhibit exceptional durability when faced with challenging environmental conditions.

In contrast, Hydraulic hinges use fluid dampers for precise control, ensuring smooth, gradual closing regardless of strong wind. This reduces wear, increases durability, and lowers maintenance. They also absorb shocks and vibrations, preventing damage and noise in windy conditions.

However, it is important to note that if the door swings open beyond 120 degrees, the hydraulic hinge is at a higher risk of breaking.

The hinges are easily installed and adjusted to comply with ADA & ICC A117.1 requirements for opening force and to assure quiet, secure closing.
