Cold storage doors are insulated, fast-acting doors designed to maintain a controlled internal temperature while allowing frequent, efficient access for goods and personnel. Rudhar Group manufactures cold storage doors in insulated PVC and PUF (polyurethane foam) construction for cold rooms, blast freezers, and temperature-controlled warehouses.
Types
- Insulated PVC fast doors: flexible, high-speed opening for frequent-access cold rooms with moderate temperature differentials.
- PUF insulated sliding/hinged doors: rigid insulated panel doors for deep-freeze and blast-freezer applications requiring higher thermal resistance.
Features & Benefits
- Insulated core minimises cold-air loss and reduces refrigeration running cost.
- Fast opening/closing cycle limits temperature fluctuation during frequent use.
- Perimeter seals and brush/rubber gaskets prevent frost build-up at the frame.
- Self-repairing PVC curtain option resists accidental forklift impact without stopping operation.
- Safety photocells and sensing edges prevent closure on an obstruction.
- Available in manual and motorized operation.
