What The Sliding Cold Storage Door Does
Howcool Manual Sliding Cold Storage Doors are designed for frequent personnel access in walk-in cold rooms and freezer rooms. The door leaf uses the same insulation as our cold-room panels — full PU foam core with galvanized or stainless-steel skin, guaranteeing zero thermal bridges. The ground anti-freeze heater prevents ice build-up at the threshold.
All doors come standard with safety escape device (releasable from inside), high-elasticity EPDM sealing strips with built-in magnetic strip, stainless-steel hardware, and aluminum-alloy guide rail. Door sizes fully customizable from 1000×1800mm up to 2500×3200mm. Single or double-leaf configurations available.
Our sliding cold storage doors are made with the same insulation material as our cold room panels, featuring double-sided color steel plates for durability. The ground part includes an anti-freezing device, while the electric heating protection device ensures safety and prevents leakage.
Why Buyers Choose This Model
Seamless Insulation
Same PU foam core as cold-room panels — no thermal bridging, no cold leakage. EPDM seal with embedded magnet for tight closure.
Safety Escape Device
Internal release handle — never trap a worker inside. Meets international cold-storage safety standards.
Anti-Freeze Heating
220V/36V automatic constant-temperature heating strip around the frame and threshold prevents ice-sealing the door shut.
Customizable Size
Single/double leaf. Widths 1000-2500mm, heights 1800-3200mm. Stainless-steel or color-coated steel skin.
Cold Room Doors Failure Modes
Cold loss at every opening
High-speed roll-up doors opening at 2.5 m/s with around 30% energy saving against a conventional door on the same traffic.
Doors that ice shut
Heated frames and gaskets rated from minus 60 to plus 120 degrees on electric sliding doors.
Damage from forklift traffic
Flip flap doors with adjustable spring hinges for constant passage, and vertical lift doors with 40 mm sectional panels where floor space is tight.
