Cellar Cooling Installation and Repair

Cellar cooler installation and repair in London

Climate Flow Limited installs, repairs and maintains cellar coolers for pubs, bars, restaurants and other venues in London and surrounding areas. Cellar cooling keeps a beer cellar or drinks store cold enough to hold kegs and bottled stock in good condition. Our F-Gas certified engineers size each system to the cellar and look after it once it is running.

What is a cellar cooler?

A cellar cooler is permanently installed refrigeration that cools a cellar or storage room using the standard cycle of evaporation, compression and condensation, as the government's Energy Technology List entry for cellar cooling equipment describes it. In a split system the evaporator inside the cellar takes heat out of the air, and the condensing unit outside, a compressor and condenser in one casing, rejects that heat to the open air. A single split system has one evaporator and one condensing unit. A dual split system has two evaporators sharing one condensing unit.

The same list rates cellar cooling equipment for storing chilled drinks below 12°C, at a cellar air temperature of 10°C. Those are rating conditions, not a setting for every cellar: what you store decides the temperature, and the engineer sets it with you.

Brands we install and service

We install and service J&E Hall cellar coolers, the make used on our Southwark cellar job. J&E Hall's Cellar Plus range reaches temperatures as low as 4°C. It uses R448A or R449A refrigerant, the fluid that carries heat out of the cellar. It allows pipe runs of up to 50m. That gives more choice over where the outdoor unit can go. These figures come from J&E Hall's Cellar Plus page. Where the unit goes on your site is settled at the survey.

We also install and service the condensing units and temperature controllers that serve cellars, including Danfoss condensing units and Eliwell controllers, for both small and large cellar spaces.

Our cellar cooler services include

• Full system design and installation
• Breakdown repair, with 24/7 emergency callouts
• Low pressure switch adjustment (the switch that reads the refrigerant pressure and stops or starts the compressor)
• Solenoid valve wiring and fault-finding (the electrically operated valve that opens and closes the refrigerant line)
• Leak testing and refrigerant work
• Condenser and evaporator coil cleaning
• Planned maintenance visits, agreed per site

Do cellar coolers need F-gas leak checks?

A cellar cooler needs F-gas leak checks if its refrigerant charge falls within the leak-check rules. The charge is measured in tonnes of CO2 equivalent: the amount of carbon dioxide that would have the same warming effect as the gas in the system. An engineer works this out for each system. Equipment in the lowest band must be checked at least once every 12 months, and the operator of the equipment is responsible for getting it checked, under the GOV.UK guidance on checking F gas equipment for leaks. A leak found during a check must be repaired as soon as possible and the system re-tested within a month.

For equipment holding F gas equivalent to 5 tonnes or more of CO2, records must be kept, including the quantity and type of gas at installation, held for 5 years (GOV.UK guidance on F gas records). Installing, servicing, leak-checking and decommissioning this equipment needs the right F-gas qualification, and a company working on equipment operated by others must be certified by an approved body. Climate Flow is F-Gas certified.

Typical applications

• Pub and bar cellars
• Microbreweries
• Drinks storage rooms
• Wine cellars
• Event venues
• Commercial kitchens

We plan each system around the room's size, insulation, ventilation and access. We also install and service beer, keg and line coolers on the bar side. Cellar cooling is one of our commercial refrigeration services, alongside cold room installation for larger chilled stores and ice machine repair and maintenance for the bar.
