Cold Room Doors
Sliding Door
Sliding cold room doors for wide clear openings and frequent handling; PU core (80–200 mm), PPGS/304 stainless/PVC surfaces, panel- or wall-mounted, freezer heaters.
Sliding cold room doors are engineered for temperature-controlled facilities—food processing, HoReCa, pharmaceutical and logistics sites—where wide clear openings, frequent handling and energy efficiency are essential. Compared to hinged models, sliding doors save space around the opening, provide smoother traffic for pallet jacks and forklifts, and maintain tight sealing to reduce heat gain and condensation.
Key Technical Features
- Smooth horizontal travel: Top rail with heavy-duty bearing rollers; stable motion with reduced operating force.
- Adjustable bottom guide: Keeps the leaf aligned and improves gasket compression for repeatable sealing.
- Thermal-bridge-reduced frame: Insulated profiles with replaceable gaskets; optional heater cable for freezer rooms.
- Insulated core: Rigid polyurethane foam at 40–42 kg/m³ density for high thermal resistance.
- Thickness options: 80, 100, 120, 150, 200 mm depending on target temperature and duty cycle.
- Surface materials: Polyester-painted galvanized steel, CrNi (AISI 304 stainless steel) or PVC-laminated sheets.
- Frame types: Panel-mounted, aluminum or PVC frames for wall or panel installation.
- Safety & compliance: Locks to international standards with internal emergency release and phosphorescent handle.

Frequently Asked Questions (FAQ)
What are the advantages of sliding cold room doors compared to hinged models?
Sliding doors save floor space around the opening, allow wider clear passages for forklifts and pallet trucks, and provide smooth operation at high traffic. They also help reduce air exchange time when correctly adjusted and sealed.
How is insulation and sealing performance ensured on sliding doors?
A PU core (40–42 kg/m³), continuous compressible gaskets, a top rail with bearing rollers and an adjustable bottom guide maintain alignment and gasket compression. For freezers, a frame or inside gasket heater prevents ice build-up and improves sealing.
Which door thickness should I choose for chillers and freezers?
As a general guide: 80–100 mm for positive-temperature rooms (+10…0 °C), 120–150 mm for freezers (−18…−25 °C), and 150–200 mm for blast applications. Final selection depends on target temperature, opening frequency and building details.
What maintenance is recommended for rails, rollers and gaskets?
Periodically clean rails and guides, check roller alignment, and inspect gasket wear and compression. Use non-abrasive cleaners and avoid harsh chemicals that may damage coatings or elastomers. Adjust the bottom guide when needed to keep sealing consistent.
Are frame or gasket heaters necessary in freezer applications?
Yes. In sub-zero rooms, integrated frame/inside gasket heaters mitigate condensation and ice formation on sealing areas and guides, protecting components and ensuring reliable closing.
