Manual Sliding Cold Room Door provides an insulated entrance for receiving and picking goods in chilled or frozen stores. The cast polyurethane body limits heat transfer through the closed leaf, while the inflatable rubber seal expands into contact with the frame to close perimeter gaps. This reduces unwanted warm air entry and cold air loss, helping the refrigeration system maintain the storage temperature between stock movements.
The operator releases the seal before moving the door by hand along its rail, then closes and seals the entrance after passage. Releasing the seal reduces rubbing during movement; horizontal travel keeps a swinging leaf out of the stock-handling approach. The wall beside the opening must remain clear for the door to slide.
PRACTICAL BENEFITS
Seal the closed entrance without dragging the seal during travel
A seal rubbing throughout opening
Releasing the inflatable seal before sliding allows movement without dragging the expanded seal against its contact surface.
A rigid leaf swinging into the handling area
Rail-guided sideways travel keeps the swing arc out of the route used by goods and trolleys.
APPLICATION ENVIRONMENTS
Cold stores with staff-operated goods access
Chilled ingredient storage
Allow staff to open the entrance for ingredient trolleys and restore the insulated, sealed boundary after picking.
Frozen-product stores
Provide hand-operated access for stock receiving and retrieval while limiting closed-door heat gain.
Refrigerated packing and dispatch rooms
Use a sliding entrance where goods move between a cooled room and an adjoining handling area with limited swing space.
SELECTION GUIDE
Coordinate door movement and seal operation
Side travel and usable passage
Keep shelving and stored goods outside the leaf’s travel, and match the clear opening to the largest load.
Inflation and release arrangement
Plan the air connection and seal operation with the doorway: the seal engages after closure and releases before sliding.
Frame and rail alignment
An aligned frame and guided leaf allow consistent seal contact when closed and clear movement when released.
COMMON QUESTIONS
About the manually operated sealed entrance
What moves the door?
The operator moves the leaf by hand along the sliding rail; manual operation describes the door movement.
Why release the rubber seal before opening?
Deflation removes the expanded seal from its contact surface, reducing dragging and rubbing as the leaf moves.
Can the opening be sized for existing trolleys?
Yes. Custom dimensions can be matched to the loads and the available side travel space.
