Technical:

• Door blade material: 750 gsm PVC-coated polyester with smooth anti-static finish.
• Door blade colour: white with blue rub strips (option of red or green rub strips).
• Top roll hood cover: the fully-enclosing hood cover, supported by substantial sub- and base-frame, is an essential part of the dry-air circulation system and additionally provides a warm air reservoir for the protection of the double top rolls, drive and geared motor unit.
• Sealing and insulation: two galvanized and powder coated seals infill the gap between the rear column and the freezer wall, enclosing a mineral wool-filled cavity with additional insulation provided by the fitting of a double-skinned PVC foam-encapsulated thermal jacket to the rear side guide and inside face of the side seal.
• Top roller: two 4 mm wall steel tubes terminating at each end with stepped stub shafts running in self-aligning bearing units, speed-synchronized via twin simplex chain drives at each side with trans-torque collet-type bushes.
• Back bar and top seal: a steel cross member bolted to the columns carries the fixing brackets and supports the top seal and a brush strip damper .
