OEM Chillers​

Aqua offer OEM chillers, with cooling capacities from 1kW to 1MW+, designed to work with process fluid temperature requirements ranging from -30˚C to +50˚C.

Free Cooling Chillers


Free cooling chillers dramatically reduce energy consumption and operating costs, helping to reduce the carbon footprint of your business or facility.

CO2 Chiller


For low temperature, process applications, you need look no further than our range of CO2 chillers. 

Propane Chillers​


Efficiency, reliability & sustainability come together with our range of Aqua Propane chillers. 

Industrial Cooling Systems

Our versatile range of chillers can cater to a wide spectrum of requirements, providing our customers with a choice of cooling capacities. Our comprehensive range of industrial chiller units are designed to achieve incredibly high-efficiency cooling with very low power consumption. In addition to this we also offer free cooling and low GWP chillers as well as OEM and process chillers.

If you are looking for a temperature control solution that can dramatically reduce energy consumption and operating costs then our free cooling solution is the answer. Aqua’s free cooling chiller range can reduce your annual cooling costs by up to 80%.. Our cooling systems are specifically designed to give our customers the best of both worlds – a highly reliable and versatile process chiller combined with all the benefits of free cooling operation.

If your business is looking for a cost-effective, ethical chiller system, choosing a chiller with a Low Global Warming Potential refrigerant will provide energy efficiency and cost savings while reducing your carbon footprint. Aqua offers a wide range of low GWP chillers to help you minimise the impact that your cooling systems have on the environment.

Future-proof your investment with low GWP chillers

If your business is looking to invest in a new chiller, then it needs to be viable over its lifetime, which can be up to 30 years, so it’s important to choose a chiller that uses a sustainable refrigerant. The refrigerant you choose can have an important effect on the energy efficiency of your chiller, the capital cost, operative costs and your green credentials. Common refrigerants have risen in price by as much as 300% in recent years because they are not as environmentally friendly as alternatives. Aqua can help support you in choosing an energy-efficient low GWP that’s cost-effective in the long-run.

By choosing a chiller with a lower Global Warming Potential refrigerant such as R32, R454B, R1234Ze or R290 instead of the traditional R410a and R134a, you’ll enhance the energy-efficiency of your chiller – providing energy cost savings while reducing your carbon footprint.

The EU is phasing down the availability of hydrofluorocarbons refrigerants (HFCs) by 79% between 2015 and 2030. By 2030, only 21% of HFCs sold in 2015 will be available. Therefore, it is important to future-proof your chiller system.

Flexible Process Cooling Systems

We understand that the demands of process applications are diverse, so our chillers are highly configurable and can be designed with a high degree of flexibility to allow for the intricacies of your specific process. However, flexibility needs to go hand in hand with reliability. Aqua offers process chillers with cooling capacities from 1kW to 1MW+, designed to work with process fluid temperature requirements ranging from -30˚C to +50˚C.

Process chillers are often the mainstay of 24/7 manufacturing, where production downtime is a no go because of the cost and impact involved. Aqua chillers are highly reliable, durable, built to last and yet competitively priced.

Our process cooling solutions come with standard options for aggressive environments. From corrosion-resistant finish to the chiller’s condenser coil and exterior panelling, for sites based near the sea. For clients working in noise-sensitive environments, we can select low noise fans and soundproofing options. Units can also be easily adapted for low/high ambient conditions, from -20˚C or +55˚C

Energy efficiency can be maximised by including electronically commutated (EC) fans and scroll, digital scroll, screw, inverter screw or Turbocor compressors. The chiller units are compatible with integrated free cooling or external free coolers and can dramatically cut energy costs and carbon footprint.

No matter what your requirements are, with over 20 years of experience in the temperature control industry we are the market leaders, designing, supplying, installing, and servicing innovative cooling solutions for purchase or hire. Our expertise and experience ensure that you get the best solution for your application.

asked questions

Chiller efficiency is the energy consumed by a chiller unit, compared to the cooling capacity achieved. It is normally given as a Coefficient of Performance, or COP, rating or, more recently, an EER (energy efficiency ratio) figure.

Chillers are often the single largest energy consuming piece of equipment within a building but there are things you can do to improve their efficiency, including:

Check the refrigerant charge – over or under charged refrigerant circuits will negatively impact efficiency.

Clean the chiller condenser – even lightly fouled condensers will affect energy consumption negatively.

Replace the thermal expansion valve with an electronic version.

Replace fans – with EC fans or the addition of an inverter. Water pumps can be upgraded like this too, giving a much more efficient alternative.

Utilise free cooling – use the lower ambient air temperature, when possible, to save on mechanical cooling, this helps your cooling equipment last longer too as there is less wear and tear on key parts like the compressor.

Scroll, screw, reciprocating and centrifugal are the three main types of compressors found within a process or industrial chiller.

Screw, scroll and centrifugal relate to the different types of compressors that are found within a chiller unit. A screw compressor has two rotors or screws. A scroll compressor has two scrolls, one fixed and one orbiting. A centrifugal compressor operates on the premise of centrifugal force. Different compressor types achieve different efficiencies depending on application and operating conditions (full load, part load for examples). The operating temperature of the chiller will also dictate which type of compressor is used in its design.
