Sliding Cold Room Doors

Sliding cold room doors provide insulated access to chilled storage, freezer rooms and temperature-controlled processing areas. The door leaf moves horizontally beside the entrance, keeping the approach clear of a hinged door’s swing arc.

Frigovetta sliding cold room door configurations address different storage temperatures and entrance layouts. Chiller and freezer specifications define the thermal application, while single-slide and bi-parting arrangements describe how the doorway opens.

Sliding Chiller Doors — Positive-Temperature Storage

Chiller sliding doors serve refrigerated spaces typically operating above 0°C (32°F). They provide access to chilled storage rooms, food preparation areas and refrigerated handling spaces.

An insulated leaf helps limit heat transfer when closed. Perimeter and floor seals help restrict air exchange around the opening, supporting separation between the refrigerated room and adjoining areas.

For walk-in cold rooms, the door specification should match the room temperature, ambient conditions and access frequency. Clear opening dimensions must accommodate daily product movement, while available wall space determines the appropriate sliding arrangement.

Sliding Freezer Doors — Frozen Storage

Freezer sliding doors are designed for frozen-storage applications below 0°C (32°F). Their insulation and sealing arrangements must suit the temperature difference between the freezer and surrounding areas.

For applications below −18°C (−0.4°F), Frigovetta equips freezer doors with heaters to help prevent the seals from freezing. This provision forms part of the low-temperature door specification.

When selecting doors for walk-in freezers, consider the required operating temperature, ambient humidity and frequency of passage. These conditions influence the thermal and frost-control requirements around the entrance.

Doors for Blast-Freezing Rooms — Around −40°C

Blast-freezing rooms require a door specification suited to more demanding low-temperature conditions. For rooms operating around −40°C (−40°F), Frigovetta uses a double-gasket arrangement alongside door heating.

The double-gasket configuration forms part of the sealing design for this application. Heating helps prevent the seals from freezing during low-temperature operation.

For blast freezer rooms, the complete door assembly and opening arrangement should be selected against the project’s operating conditions. An ordinary freezer designation alone does not establish suitability for blast-freezing service.

Bi-Parting Sliding Doors — Two-Leaf Opening

Bi-parting sliding doors use two leaves that move away from the centre in opposite directions. This distributes the required parking space between both sides of the entrance rather than placing a full-width leaf on one side.

The arrangement can suit wide openings where one side cannot accommodate a single sliding leaf. Both sides still require sufficient wall space and track clearance.

Bi-parting describes the opening configuration, not a separate temperature class. The door’s insulation, seals and heating provisions must match its intended chiller, freezer or other specified low-temperature application.

Opening dimensions should accommodate the largest load passing through the entrance, including handling equipment and the necessary clearance.

Installation and Project Requirements

Coordinate the door opening with insulated cold room panels, floor levels and the supporting structure. Installation planning should provide adequate sliding clearance and access to components requiring inspection or maintenance.

Send Frigovetta the required room temperature, ambient conditions, clear opening dimensions and traffic details to discuss a suitable sliding cold room door configuration.
