Cold Storage Swing Doors

Cronax Cold Storage Swing Doors are engineered to provide reliable insulation, easy operation, and long-lasting durability in temperature-controlled environments. Ideal for cold rooms, walk-in freezers, supermarkets, food processing facilities, and pharmaceutical storage areas, these doors are built to maintain consistent temperatures while withstanding frequent usage.

Constructed with high-density polyurethane (PUF) or polyisocyanurate (PIR) insulation, the door panels deliver excellent thermal efficiency and energy savings. Heavy-duty hinges and door frames ensure smooth swing action, while flexible gaskets create a tight seal to minimize air leakage, condensation, and frost build-up. The design allows for both single and double-leaf configurations, making them suitable for a wide range of cold storage applications.

Available in manual and self-closing options, Cronax Cold Storage Swing Doors can be customized in size, finish, and hardware to meet specific operational requirements.
