Polar U-Series 1.8 x 1.8m Integral Walk-In Cold Room

The Polar U-Series integral walk-in cold room is a self-contained chilled storage unit designed for commercial kitchens requiring substantial, reliable refrigerated capacity. Unlike modular cold room systems that require separate refrigeration plant, this integral unit houses the refrigeration system within the structure itself, simplifying installation and reducing the need for additional mechanical equipment. The grey galvanised steel, aluminium, and plastic construction provides a robust, commercially appropriate finish suited to back-of-house environments.

In operational terms, this cold room is built to maintain consistent chilled temperatures even when the surrounding ambient temperature rises significantly — a relevant consideration for sites where the unit may be sited in a warm kitchen, loading bay, or external position. The forced-air cooling system circulates cold air evenly throughout the interior, which helps protect stock quality and reduces temperature stratification during frequent door openings — a common issue in high-throughput operations where staff access the room regularly throughout a service.

From a practical standpoint, several design details translate well into day-to-day kitchen operation:

• Self-closing door seals flush against the cold room walls, reducing cold air loss and supporting lower running costs
• Lockable door with an internal safety release mechanism to prevent accidental lock-ins — a requirement under most food safety and health and safety guidelines
• Non-slip floor surface reduces slip risk in a working cold room environment
• Coved internal floor-to-wall junctions limit dirt and liquid build-up, making routine cleaning more straightforward
• R449A refrigerant is a lower-GWP option compared to older refrigerants, which may be relevant to operators considering environmental compliance

On installation, the unit's 400kg weight means structural floor loading should be confirmed before siting, particularly in older or upper-floor locations. The unit is intended for indoor installation as standard; if outdoor placement is required, a weather-resistant roof panel is available separately and should be factored into the project. Internal racking and shelving are not supplied with the unit and will need to be sourced separately — worth planning before installation so the room is operational from day one. Access routes to the installation site should be checked given the assembled dimensions, as delivery in parts or via specific access points may need coordinating.

This cold room is well suited to mid-sized catering operations — restaurants, hotel kitchens, catering production units, and similar sites — where walk-in chilled storage is needed but available footprint is limited. The 1.8 x 1.8m floor area provides meaningful storage capacity without requiring the space demands of larger walk-in configurations. For higher-volume operations or sites needing a greater storage footprint, larger variants within the U-Series range are worth considering. Equally, if your requirement is more modest, a smaller integral cold room may be a more proportionate fit.
