Description

SCR double-leaf sliding door for wide openings in cold rooms

The SCR double-leaf sliding door covers wide openings while maintaining the cold room’s thermal insulation, without needing a single large, heavy panel. Each leaf slides in the opposite direction, reducing the space needed for opening and allowing clear openings of 2.5 to 5 m with easy manual or motorised operation.

Technical specifications

  • Type: two-leaf sliding door, centre opening to both sides
  • Each leaf with polyurethane sandwich panel (50-100 mm depending on temperature)
  • Guide system with a common top rail for both leaves
  • Central meeting gasket between leaves with high-tightness seal
  • Extruded aluminium or stainless steel frames
  • Synchronised motorisation of both leaves (optional)
  • Presence detector or safety sensor (as required by regulations)

Advantages

✔ Covers wide openings without excessively heavy panels
✔ Easier manual opening thanks to lower weight per leaf
✔ Ideal for cold rooms with double access or high goods turnover
✔ Airtight central closing system that ensures insulation across the full width
✔ Synchronised motorised opening for hands-free operation

Applications

Large cold rooms with wide machinery access; logistics warehouses with double forklift access; ripening rooms with wide access for trays and trolleys; service access in large food processing facilities.

Standards and compliance

Automatic double-leaf doors for industrial use comply with the Machinery Directive 2006/42/EC and must include anti-trapping safety devices. Insulation meets the requirements of EN 378 for refrigeration installations.

FAQs

Does the meeting gasket between the two leaves provide the same insulation as a single-leaf door?

With correct design and quality materials, the central meeting gasket between the two leaves is equivalent in insulation to the standard perimeter gasket. The key is the design of the central overlap, which usually incorporates an EPDM or neoprene profile that compresses on closing and completely seals the joint.
