Product Description
Designed for cold‑chain logistics and freezer warehouses, this cold‑storage sectional overhead door solves condensation, frosting and cold‑loss points in low‑temperature spaces. Thick high‑density PU panels, thermal‑break structure and low‑temperature‑adapted components keep stable thermal performance under sub‑zero working conditions, reducing energy consumption of refrigeration units.
This low‑temperature sectional overhead door is customized for chill rooms and deep‑freezer warehouses. It adopts extra‑thick insulated sandwich panels with thermal‑break design to block cold‑heat bridge. The whole set of hardware, motor and sealing system are optimized for low‑temperature environment to prevent grease solidification, ice‑block jamming and heavy cold‑air leakage during frequent opening‑closing cycles.
80‑100mm high‑density CFC‑free PU foam sandwich panel, internal thermal‑break isolation structure, avoid cold bridge transmission between inner and outer steel skins, reduce surface condensation risk.
Galvanized track, hinges and roller assembly filled with special low‑temperature anti‑freeze lubricant, prevent grease hardening under minus‑degree environment; reinforced torsion spring group for heavy‑weight thick panels.
Special cold‑storage motor with built‑in heating module, control box anti‑condensation heating function, guarantee normal startup under deep‑freezer ambient temperature.
Multi‑chamber low‑temperature resistant EPDM sealing strips for top, side and bottom; optional heating wire on bottom seal and door frame to melt frost and ice accumulation.
- Extra‑thick PU panel plus thermal‑break structure, greatly reduce cold‑loss of cold‑storage warehouse
- Complete anti‑frost & anti‑condensation solution for freezer sub‑zero working environment
- Low‑temperature‑adapted motor, control and lubrication system, no jamming under cold condition
- Multi‑layer sealing strips block cold‑air outflow and humid‑hot air infiltration
- Optional cold‑storage wicket door, heating‑wire assembly for different cold‑chain scenarios
