The Ultimate Guardian of Cold Chain: High-Performance Cold Room Doors

Cold storage doors serve not only as access points but also as critical barriers against cold air loss. Our range of cold storage doors is engineered for demanding industrial environments, achieving a perfect balance between exceptional thermal insulation and smooth operation. Whether for high-traffic logistics centres or pharmaceutical warehouses with stringent requirements, we provide tailored solutions.
Utilising high-pressure polyurethane (PU) foam as core material eliminates thermal bridging. Our unique seal design ensures airtight closure, effectively blocking heat exchange between interior and exterior spaces. This significantly reduces refrigeration unit load, saving you every kilowatt-hour.

Core Features:
Thermal Break Design: Frame incorporates thermal break insulation technology to prevent condensation and cold air leakage.
Safety First: All cold storage doors incorporate an internal escape mechanism (Safety Release). Even when locked, the door can be easily pushed open from within, ensuring personnel safety.
Anti-Freeze Heating (Frame Heater): Low-temperature freezer doors come standard with frame heating elements. This effectively prevents ice build-up and adhesion on the door seal, ensuring smooth operation at all times.
