Rising Hinge for Cold Storage Doors HNG21433 – Adjustable, 30 kg Capacity

Product Description:

The HNG21433 cold storage door hinge is a high-performance component engineered for light to medium-duty industrial doors. Manufactured from high-grade composite materials and featuring a galvanized steel pin, this hinge is fully resistant to corrosion, moisture, and extreme sub-zero temperatures typical for walk-in freezers and cold rooms.

The standout feature of the HNG21433 model is its advanced adjustability. It allows for precise alignment of the door leaf with the frame, ensuring maximum thermal efficiency. The integrated rising mechanism (cam-lift) lifts the door by 8 mm when opening from 0° to 90°, which significantly reduces floor gasket wear and makes door operation effortless.

Key Features & Benefits:

• Rising Mechanism (Cam-Lift): Automatically lifts the door leaf by 8 mm to protect the bottom threshold gasket from friction and damage.

• 2D Precision Adjustment:

Vertical: +/- 20 mm, allowing for perfect compensation of door sagging.

Gasket Compression: +/- 4 mm, ensuring a tight seal to prevent energy loss.

• Universal Design: Fully reversible construction, suitable for both left-hand and right-hand doors with an opening angle of up to 180°.

• Adaptable Offset: With optional distance plates (available in 5 mm, 10 mm, and 20 mm), the hinge supports door leaf offsets ranging from 67 mm to 120 mm.

• Heavy-Duty Mounting: Secure installation with 8 screws (5.5 - 6 mm diameter) provides stability for doors up to 30 kg (per pair).
