One thing our engineers are often asked is “why are Process Chillers designed differently from Air Conditioning Chillers?”. The answer is relatively straightforward. Process chillers are designed to run 24/7 with varying load and ambient climatic conditions, on an ongoing basis. Whereas Air Conditioning Chillers are designed to run at full load during summer months. Then are effectively redundant in the midst of winter.

At Aqua we pride ourselves on offering a range of Process Cooling Solutions for either purchase or hire. Designed and manufactured to a standard where “commercial just isn’t good enough”. Our robust frame work, impeccable paintwork and overall design of the packaged unit, ensures that we provide the highest quality unit each and every time.

Finance Solutions

Aqua Group have a range of Finance Solutions available on most temperature control units – Our lease purchase finance option is becoming increasingly popular with clients, especially those looking to protect their capital expenditure budget during economically uncertain times. It enables you to secure new temperature control equipment but without the hefty up-front investment that comes with outright purchase. With a lease agreement you pay a fixed monthly cost over an agreed time-period, after which you then own the equipment… Read More About Our Finance Options

Case Study

Aqua Keeps Ice Cream Churning

Aqua Group have installed innovative technology to an expanding ice cream manufacturer. Marshfield Farm had an existing cooling system from Aqua but wanted to expand the existing set up to cope with increased product demand. The organic dairy and arable farm, based north of Bath, has more than doubled its ice cream production over the past 10 years. It produces over 30 flavours of award-winning premium ice cream and sorbet, all made with the farm’s own organic milk and all-natural ingredients. Aqua supplied and installed a 200kW Adiabatic cooler Group system and 75kW of chillers to supplement Marshfield’s existing set up. The state-of-the-art Cooling technology not only helps increase production capacity as demand for the farm’s ice cream reaches new heights, but also optimises energy efficiency. Innovative design resulted in a system with a regeneration capacity, meaning the need for expensive refrigerated water is reduced by around 90%. The heat that is created when the product is pasteurized is recovered and recycled and then chilled water is just used to cool the product to 4°C for packaging. Full cooling capacity is only needed for the first and last cycle of the day.

Wide Range Of Process Chillers

As Process Chillers can often have varying demands, and return water temperatures, Aqua’s units are designed to take higher water temperatures that those of any of our competitors. Our small to large Process Chillers will happily run at 30°C water, when required. Our buffer tank and pumping systems make sure that the refrigeration side of things works effectively. As well as protected from the process at all times.

Our Process Cooling Chillers can be supplied in 304 or 316 stainless steel frame and hydraulic systems. The units can be tailored for coastal and aggressive atmospheric conditions and for ambients from -40°C to +55°C. Making them ideal whether your project is in the frozen lands of Siberia or the searing desert heat of the Middle East. In addition, Aqua’s units can be tailor made to provide fluid at all temperature pressures and flow rates for very little additional cost.

Our N+1 and N+N systems give you continual operation. Plus the peace of mind that the cooling of your process will be uninterrupted in the rare event of a component breakdown. With A & B power switching, run and standby pumps and fault default settings. Our process chillers stay running 24/7.

Quality really matters at Aqua and we are committed to providing you with a system that will work more efficiently. That will also last far longer than one supplied by our competitors.
