Core Door Features
Designed for safer and more reliable freezer access
Airbag Bottom SealBottom airbag sealing helps the freezer door close tightly against the floor and reduce air leakage.
Fold-Up Lifting SystemThe belt lifting method raises the insulated curtain in stacked sections for stable high-frequency operation.
FROG PUPIL ControlIndustrial intelligent control supports variable-frequency energy-saving operation and real-time status display.
Insulated Door Curtain0.8 mm curtain plus 10 mm insulation filling creates a 14 mm thermal barrier for freezer door applications.
Performance
Built for freezer entries, warehouse routes and production corridors
The SEPPES freezer door can be installed at manual traffic openings, cold storage partitions and refrigerated logistics routes. Its stainless steel frame, insulated curtain, tight sealing and control system are suitable for facilities that need both fast access and temperature protection.
Energy-saving accessShorter opening time helps reduce cold-air exchange and supports refrigeration efficiency.
Safer movementInfrared safety photo eyes and emergency manual opening support daily industrial use.
Project-ready installationCompatible with freezer rooms, cold storage panels, wall openings, insulated rooms and automated access signals.
