Industrial Chillers

Does your business use process fluids or heavy-duty machinery that generates heat? An industrial process chiller can help to regulate temperature and avoid issues caused by overheating.

The team at Sub-Zero can supply, install, and repair a wide range of industrial chiller units, designed to meet the requirements of a multitude of industrial applications. Our engineers have years of experience installing temperature controlling solutions across South Wales and The West. 


Our team of engineers can be relied upon for a seamless installation, in accordance with F-Gas and Refcom regulations. Regardless of the capacity you require, the team can design a chiller solution designed to meet your unique business requirements.

We provide the following as part of our installation process:

  • Full site survey
  • Full project proposal
  • Full analysis of the project requirements
  • An energy-efficient chiller
  • Where relevant safe removal and disposal of existing chillers
  • Any maintenance and repair requirements

At Sub-Zero, we are typically asked to install air-cooled and water-cooled chillers. 

Air-cooled Chillers

Air-cooled chillers rely on ambient air to cool hot refrigerants, these chillers provide businesses with the following benefits:

  • Typically used for small, medium, and large applications
  • Outdoor installation – as they rely on ambient air being cool
  • Energy efficient
  • Cooling-only or heat pump
  • Choice of swing, scroll or screw compressor
  • Tend to last 15-20 years
  • Typically, less expensive than water-cooled chillers

Water-cooled Chillers

Unlike air-cooled chillers, water-cooled chillers rely on water to cool hot refrigerants. One key difference between an air-cooled and water-cooled chiller is that water-cooled chillers possess a cooling tower. Businesses can benefit from the following when opting for a water-cooled chiller:

  • Typically used for medium-large applications
  • Indoor installation – can be used in high-temperature environments as they don’t rely on cool, ambient air
  • Highly energy efficient
  • Cooling-only or cooling/heating-only
  • Choice of scroll, screw, or centrifugal compressor
  • Tend to last 20-30 years
  • Typically, more expensive than air-cooled chillers

You should consider the space, environment temperature, accessibility to water and your budget restraints when deciding whether to choose a water-cooled or an air-cooled chiller.

Feeling overwhelmed and unsure as to what chiller is most appropriate for you? Not to worry, the team at Sub-Zero will listen to your unique requirements and make recommendations on which chiller would be better suited to your application.

Chiller repair & maintenance

Even the most robust of chiller solutions can fall short if not properly maintained and serviced. At Sub-Zero, we can conduct a full service and complete any necessary maintenance work.
