Cold Room Doors
Hinged Door
Highly customizable, reliable hinged cold room doors—rising hinges, 60–200 mm PU, PVC or 304 SS,inside emergency release and more...
Hinged cold room doors are designed for temperature-controlled facilities such as food processing, HoReCa, pharmaceuticals and logistics. They are optimized to minimize heat loss, prevent condensation or frost formation, and maintain hygiene. Compared with standard doors, they stand out with leaf/frame designs that reduce thermal bridging, tight sealing gaskets, optional anti-frost heaters, and internal emergency release mechanisms.
Key Technical Features
- Rising & adjustable hinges: As the door opens, the leaf slightly rises, preventing floor friction and wear.
- Frame heater: Optional heating resistance integrated into the door frame or gasket area, preventing freezing in deep-freezer applications.
- Insulated core: Polyurethane injected at a high density of 40–42 kg/m³ ensures superior thermal insulation.
- Thickness options: Door leaf and frame available in 60, 80, 100, 120, 150, 200 mm, depending on application requirements.
- Surface materials: Polyester painted galvanized sheet or CrNi (AISI 304 stainless steel); optional color-coated finishes available.
- Frame types: Wall- or panel-mounted options including wood, PVC, and aluminum frames for easy installation and alignment.
- Safety & compliance: Locks comply with international standards and include an internal phosphorescent emergency release handle.
- Custom production: In addition to standard sizes, bespoke dimensions can be manufactured upon request.

Frequently Asked Questions (FAQ)
Hinged or sliding: when is a hinged door the better choice?
Hinged doors are ideal for personnel access, low to medium traffic areas, or compact spaces where a single-leaf opening is sufficient. They ensure fast sealing and easy maintenance. For larger passages or heavy forklift traffic, a sliding door is recommended.
Which door thickness (60/80/100/120/150/200 mm) suits which temperature range?
Typical guide: 80–100 mm for chill rooms (+10…0 °C), 120–150 mm for frozen storage (−18…−25 °C), and 150–200 mm for blast freezers. Final selection depends on target temperature, door cycle frequency and wall configuration.
Which surface material (PPGS, PVC, 304 stainless steel) is most suitable for food areas?
304 stainless steel offers maximum hygiene and corrosion resistance, ideal for food processing zones. Polyester-coated galvanized steel (PPGS) is suitable for general or low-risk areas. Surface selection should consider chemical exposure and cleaning frequency.
Are internal emergency release and anti-panic handle mandatory?
Yes. Internal emergency release is a safety requirement for all cold rooms. Doors include a phosphorescent anti-panic handle that allows exit even during power failure or locked state.
How should frame types (panel, aluminum, wood, PVC) be selected?
Panel-mounted frames provide quick installation and seamless alignment. Aluminum frames are lightweight, corrosion-resistant and long-lasting. PVC frames are economical and compatible with insulated panels or masonry walls. Wood frames allow thermal bridge control and flexible on-site fitting. The final choice depends on humidity, chemical exposure, and mounting structure.
Which accessories are recommended (window, kick plate, threshold heater, switch)?
Inspection windows improve visibility and safety (heated glass for freezers). Kick plates protect the leaf against trolley or pallet impact. Threshold or frame heaters prevent ice buildup in freezer rooms. Door switches enable control of lights, fans, or interlock systems.
What should be considered regarding cleaning and chemical resistance?
Use neutral or mildly alkaline detergents; avoid chlorine-based, highly acidic/alkaline or solvent cleaners that may damage surfaces and gaskets. Avoid direct water pressure on door hardware; instead, use damp cloth cleaning to extend gasket and hinge life.
