Blast Chiller Repair and Installation

Commercial blast chiller services for food safety

Climate Flow Limited carries out blast chiller repair, servicing and installation for restaurants, bakeries, caterers and food production kitchens across London and surrounding areas. A blast chiller is the cabinet a kitchen uses to cool cooked food quickly. When it stops pulling the temperature down, the kitchen's cooling routine stops with it. Our F-Gas certified engineers find the fault, repair it and keep the unit maintained.

Blast chillers are one part of our commercial refrigeration services, alongside cold rooms, cellar coolers and ice machine repair and servicing.

What is a blast chiller?

A blast chiller is a refrigerated cabinet that drives cold air hard across the food. It brings freshly cooked dishes down in temperature much faster than a standard fridge, which is built to hold food that is already cold.

Cooling speed matters for food safety. Food Standards Agency guidance says hot food that is not served straight away must be kept at or above 63°C. It can stay below 63°C for up to 2 hours, and after that it should be cooled as quickly as possible to 8°C or below, or thrown away (GOV.UK, cooking food safely). The same guidance says bacteria can grow in food kept between 8°C and 63°C. In England, Wales and Northern Ireland the law requires chilled food to be kept at 8°C or below (GOV.UK, chilling and freezing).

A blast chiller helps a kitchen to:

• move cooked food through that temperature range quickly
• cool batches before they go into chilled storage
• work to a written cooling method, such as the chilling down hot food safe method in the FSA's Safer Food, Better Business pack for caterers

Caterers, central kitchens, bakeries and food production sites use them.

Our blast chiller services

• Supply and installation of new units
• Breakdown repairs, with 24/7 emergency callouts
• Controller calibration and diagnostics
• Probe, fan and compressor replacement
• Refrigerant leak detection, repair and recharge
• Routine servicing and planned preventive maintenance (PPM), a schedule of visits agreed per site

We install and service Foster and Williams blast chillers. If yours is another make, give us the model when you call.

Refrigerant work is regulated. F gas means the fluorinated refrigerant gases in the cooling circuit. A company that installs, repairs, maintains or decommissions refrigeration equipment containing F gas for others must hold F gas company certification. Its technicians need F gas qualifications to service systems, check for leaks and recover gases. Users of the equipment and the technicians who maintain it share responsibility for stopping leaks. Equipment holding 5 to less than 50 tonnes CO2 equivalent of F gas must be leak-checked at least once every 12 months, so the legal duty for a blast chiller depends on its refrigerant charge. Climate Flow is F-Gas certified.

Common issues we fix

• Unit not reaching chilling temperature
• Temperature probe failure
• Fan or compressor not working
• Alarms or error codes on the display
• Ice build-up on the evaporator coil (the cold coil inside the cabinet that the fan blows air across)
• Water pooling inside the cabinet

If a blast chiller fails during service, food hygiene guidance allows chilled food to be kept out of the fridge for up to 4 hours, after which it must be thrown away. Move food to working refrigeration and note the time.

Blast chiller installation

Our engineers can help you choose the right blast chiller based on:

• Chilling or freezing capacity
• Internal volume
• Energy use, from the manufacturer's data
• How it fits your kitchen layout

We handle the job from delivery to commissioning: positioning, pipework, drainage and controller setup, with the refrigerant work done by F-Gas certified engineers. Where a kitchen needs more chilled storage than a cabinet holds, a walk-in unit is the next step. Our cold room installation service covers those, as in our walk-in cold room and freezer installation at King's Cross St Pancras Station.
