Cold Room Installation

Climate Flow Limited carries out cold room installation across London and surrounding areas: walk-in chiller rooms and walk-in freezer rooms, designed, built and installed for retail, hospitality, food storage and pharmaceutical sites. A cold room is an insulated room with its own refrigeration system, used to hold chilled or frozen stock in bulk. We survey the site, build the room, commission the refrigeration and hand it over to your team.

Custom cold rooms for any business

We build and install cold rooms for:

• Supermarkets and convenience stores
• Butchers and fishmongers
• Restaurants and takeaways
• Food manufacturers and wholesalers
• Commercial kitchens and hotels
• Laboratories and pharmaceutical storage

From compact storage to multi-room facilities, we size each cold room to its temperature, its space and what it has to hold. Cold rooms sit within our commercial refrigeration services, alongside the repair and maintenance work that keeps them running.

Our cold room installation process

1. Site survey and consultation. We assess the space, the power supply, the insulation needed and what the room will store, then give a no-obligation quote.
2. System design and equipment. We specify the insulated panels and the condensing unit for the room and the site. The condensing unit is the outdoor part of the refrigeration system. Danfoss, for example, describes its Optyma Slim Pack as a compact outdoor condensing unit for commercial refrigeration.
3. Installation and commissioning. Our engineers handle ground preparation, panels, pipework, electrics, refrigerant charging, pressure testing and controller set-up.
4. Handover. Your staff get operating instructions, the documentation for the system and the options for planned maintenance.

How we build cold rooms, and the rules they meet

Our cold rooms are built from insulated panels, sealed for hygiene and fitted with refrigeration sized to hold the room at its set temperature. We install and service Danfoss (including Optyma), Tecumseh and Foster equipment.

Temperature is the first rule. In England, chilled food must be kept at 8°C or below, and GOV.UK guidance is to set fridges to 5°C or below so food stays cold enough.

Refrigerant work is the second. F gas is the group of fluorinated gases used as refrigerant in many cooling systems. A company that services equipment containing F gas for other people must be certified by an approved body, and every technician needs their own qualification. Climate Flow is F-Gas certified. The rules set thresholds by the size of the refrigerant charge, measured as its carbon dioxide equivalent. Once the room is running, a system above the lowest threshold must be leak checked at least once every 12 months, and more often when it holds a larger charge. The user of the equipment and the technician who maintains it share responsibility for those checks. Where the system holds F gas equivalent to 5 tonnes or more of carbon dioxide, records of the leak checks must be kept for 5 years.

Cold room types we install

• Chiller rooms, set to 5°C or below for chilled food
• Freezer rooms
• Dual compartment rooms: a chiller and a freezer behind one set of panels
• Remote condensing units and modular systems
• Low-temperature blast freezer rooms

A blast chiller brings cooked food down in temperature quickly before it goes into storage; for cabinets rather than rooms, see blast chiller installation and repair. In a pub or bar, a cellar cooler, the refrigeration unit that keeps a beer cellar cool, often does the job a cold room would: see cellar cooler installation.

Signs your cold room needs attention

• The display reads above the 5°C setting, or chilled stock is close to the 8°C legal limit (see our guide to commercial fridge temperature)
• Door seals torn, or the door not closing fully

Each of these is worth a call before stock is at risk. If the room runs on a Carel unit, our guide to reading a Carel controller explains its display and alarms.

Why choose Climate Flow?

• F-Gas certified engineers
• 24/7 emergency callouts
• Survey, design, installation and handover handled by one team

At King's Cross St Pancras Station we installed a walk-in cold room and freezer for a food preparation area; the walk-in fridge and freezer installation case study shows the job.

Areas we cover

We install cold rooms across London and surrounding areas, including Wembley, Harrow, Edgware, Watford, Stratford, Croydon, Ealing and Slough.
