Hinged Cold Room Doors
Premium Hinged Cold Room Doors: High-Performance Solutions for the Cold Chain
Hinged cold room doors are one of the most critical components of industrial refrigeration systems, playing a vital role in maintaining energy efficiency and preserving product freshness. Manufactured to world-class engineering standards, our doors are designed to integrate seamlessly with sandwich panels, reinforced concrete walls, and a wide range of specialized applications.
Technical Features & Versatile Design
We combine the durability demanded by the refrigeration industry with advanced engineering technologies. Our door systems are available in various types and configurations to meet different operational requirements.
- Wide Product Range: Available as single-leaf, double-leaf, half-leaf, and monorail passage door systems.
- Superior Insulation Performance: Door leaves are available in 80 mm and 100 mm thicknesses, insulated with 100% polyurethane foam at a density of 42–45 kg/m³, providing maximum thermal insulation.
- Temperature Compatibility: Optimized for both positive-temperature cold rooms (+°C) and negative-temperature frozen storage rooms (-°C).
- Hygienic Material Selection: No wood is used in any part of the door construction, ensuring long-term structural integrity and superior hygiene. Door frames are available in two options:
- High-quality PVC frames
- Extra-durable aluminum frames with integrated thermal barriers
- Threshold Options: Available with or without thresholds to suit different floor structures.
- Sealing System: All door models are equipped with EPDM gaskets. Special corner sealing gaskets are mechanically fitted without adhesive, ensuring maximum airtightness and outstanding thermal insulation.
Engineering Excellence: Rising Hinge System
At the heart of our hinged cold room doors is an intelligent rising hinge system, specifically engineered for demanding industrial environments.
- Automatic Lifting Mechanism: As the door opens, the leaf is slightly lifted, eliminating floor friction and ensuring effortless operation.
- Hermetic Sealing: During closing, the door leaf descends to compress the bottom gasket firmly against the floor, providing an airtight seal that minimizes energy loss and reduces operating costs.
Customizable Features for Industrial Applications
Depending on the application requirements, our doors can be equipped with a variety of optional features:
- Thermally insulated vision windows for safe interior observation.
- Heavy-duty impact protection bumpers designed for forklift and pallet traffic.
- Installation with or without thresholds according to floor construction.
- A wide selection of colors and surface finishes.

Cold Storage Sliding Door
High-Performance Sliding Cold Room Doors: Redefining Safety and Efficiency
In industrial refrigeration applications, speed, airtight sealing, and reliability are essential. Designed in accordance with international standards, our sliding cold room doors deliver maximum performance for sandwich panel systems, reinforced concrete structures, and custom-built cold storage facilities.
Advanced Technical Features
Engineered for modern cold chain operations, our sliding cold storage door systems provide exceptional thermal stability even under the most demanding operating conditions.
- Flexible Configurations: Available in single-leaf, double-leaf, and monorail-compatible designs.
- Superior Thermal Insulation: Door leaves are available in 80 mm and 100 mm thicknesses and insulated with 100% polyurethane foam at a density of 42–45 kg/m³, minimizing energy loss while delivering maximum thermal efficiency.
- Wide Operating Temperature Range: Designed for reliable operation in both positive-temperature cold rooms (+°C) and negative-temperature frozen storage facilities (-°C).
- Threshold Options: Available with or without thresholds to accommodate forklift traffic, pallet handling, and pedestrian access.
Innovative Frame Technology & Superior Thermal Insulation
To maintain the highest hygiene standards, no wood is used at any stage of the manufacturing process. Our doors are available with three frame options specifically designed to minimize thermal transfer.
- PVC Frame: Provides excellent thermal insulation performance.
- Aluminum Frame: Offers exceptional durability for demanding industrial environments.
- Thermal Break Hybrid Frame: Combines aluminum and PVC to eliminate thermal bridging while maximizing both structural strength and insulation performance.
Intelligent Kinetic Sealing System
Our sliding door systems feature an advanced operating mechanism that extends gasket life while ensuring perfect airtightness.
As the door opens, the leaf lifts slightly to eliminate friction with the floor, reducing wear on the sealing gasket. During closing, the door automatically lowers into position, compressing the bottom seal against the floor to create a hermetic seal that minimizes energy loss and preserves cold room efficiency.
Industry-Leading Safety: Inverted Top Rail System
We are redefining occupational health and safety standards with our exclusive Inverted Top Rail System.
As the first and only manufacturer in the world to utilize this innovative technology, we have developed a system that prevents the door from disengaging from its track, effectively eliminating door-related workplace accidents. This unique design provides maximum operational safety while ensuring smooth and reliable performance under intensive industrial use.
