Cold Storage Hinged Doors

Cronax Cold Storage Hinged Doors are engineered to provide superior thermal insulation and reliable performance for cold rooms, walk-in freezers, and temperature-controlled facilities. Designed with precision, these doors minimize energy loss and maintain consistent internal temperatures, ensuring the efficiency and safety of perishable goods.

Constructed using high-quality materials, the door panels are filled with high-density polyurethane (PUF) or polyisocyanurate (PIR) insulation, providing excellent thermal resistance and long-lasting durability. Each door is equipped with specialized gaskets to ensure an airtight seal, preventing condensation, frost build-up, and energy wastage. Options like heated door frames, kick plates, and emergency safety releases are also available for added functionality and safety.

Available in both single-leaf and double-leaf configurations, Cronax Cold Storage Hinged Doors can be customized in size, thickness, and finish to suit your facility’s requirements.
