Cold Storage Sliding Doors

Cronax Cold Storage Sliding Doors are designed to optimize space and ensure reliable thermal insulation in temperature-controlled environments. Built for smooth operation and durability, these doors are ideal for cold rooms, walk-in freezers, food processing plants, pharmaceutical facilities, and large warehouses where efficient movement and strict hygiene are critical.

The door panels are insulated with high-density polyurethane (PUF) or polyisocyanurate (PIR) to deliver superior thermal resistance and energy efficiency. Precision-engineered gaskets create a perfect seal, reducing air leakage, preventing condensation, and minimizing frost build-up. The robust sliding mechanism allows effortless operation, even in heavy-duty applications, while optional automatic systems further enhance speed and convenience. Available in manual and motorized versions, Cronax Cold Storage Sliding Doors can be customized in size, thickness, and finish to match specific facility needs.
