The multi-composite frame is specifically suited for freezer applications as the composite material has a low conductivity for temperature. The frame is specially constructed to create a natural thermal barrier. The C FREEZER 5 is installed inside the freezer area.
The C FREEZER 5 has a flexible triple-layer curtain with integrated air mattress (U = 1,97 W/m².K) to reduce conductive temperature loss through the curtain. The sides of the curtain have additional sealing flaps for an enhanced peripheral closing on the vertical side guides. Thanks to this design, no additional sliding door is required for overnight closing.








The C FREEZER 5 door is engineered to resist extreme cold and provide precise environment control, making it ideal for food industry applications where safety is a top priority. Its smart design ensures low maintenance and high durability, offering reliable performance even in the most demanding settings.
A key feature is the food grade curtain, made from materials specifically adapted for use in food processing environments. This ensures compliance with industry standards for hygiene and safety.
The door’s multi-composite frame enhances durability. The tough side guides can absorb impacts without becoming permanently distorted, helping to avoid costly repairs. The corrosion- and paint-free materials ensure long-lasting performance, even in corrosive or aggressive environments.
For better operation and a longer lifetime, the C FREEZER 5 utilizes the unique and patented folding guide of the Trekking Fold-Up technology. This guarantees correct bar-to-bar folding of the curtain, optimizing the door’s function and extending its service life.
Direct drive technology powers the door with a proven, reliable motor. By eliminating chains, this technology reduces maintenance needs and general wear. With only five moving parts—the motor, gearbox, limit switch, winding shaft, and rotating sleeve—the door offers long-lasting, trouble-free operation.
Overall, the C FREEZER 5 provides an efficient, safe, and hygienic solution for cold storage areas in the food industry, ensuring optimal performance and durability.
