Free Cooling – Aqua offer Free Cooling either integrated and factory fitted, or as a bolt-on option that can be retro-fitted to existing industrial equipment – the technology gives incredible energy and cost savings across the board.

Aqua’s desire to sell and improve existing industrial cooling systems goes hand in hand with our Free Cooling technology. Whether it’s a separate bolt on Free Cooler or our range of energy saving industrial Free Cooling Chillers, both reduce electrical power usage by utilising lower ambient air temperatures to cool the return water whenever possible, with as little as a couple of kw’s in the winter months.

Free Cooling Chillers work by the unit sensing both the return fluids temperature and ambient air temperature. When the ambient falls below that of the return water temperature a modulating valve, or other system, activates to pass the fluid through a coil that exchanges the heat in the fluid to the ambient air, by just the mechanical effect required to drive the fans to pull the air through the coil. Therefore reducing the load either partially, or totally, if the ambient air is low enough, and reducing the power required to drive the refrigeration system.

What are the other advantages of Free Cooling? Well if we can reduce the running time of your refrigeration system by 50% then we can make your refrigeration systems last twice as long. Also there is always an element of back up, if your chiller should ever partially or totally fail the Free Cooler will continue to operate.

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

Free Cooling Hire

Aqua also offer a range of Free Cooling Hire solutions – for when Hire, rather than outright purchase is the best solution for your business. Hire can be the perfect option for clients with a temporary, emergency or a seasonal requirement. In addition Aqua also offer short to long-term, or contract lease Hire, for clients who have a more permanent requirement.

All of our Free Cooler Rental systems are readily available, competitively priced and easy to install. Aqua also has a range of ancillary equipment to ensure that your rental system performs exactly as it needs to. Our dedicated Hire sales team are on hand to help you with selection, sizing and technical advice and all of our equipment is backed up by 24/7 aftersales support.

Thermosyphoning Free Cooling

Our Turbocor Chillers have a highly sophisticated thermodynamic cycle system that, if Glycol is not acceptable within the Cooling system, can be done on plain water but eliminates the freezing issues as the refrigerant is cooled by ambient air not the fluid.

This technologically advanced solution will beat all but most separate bolt on Free Coolers where Glycol cannot be accepted in the process. It requires no extra Heat Exchangers/Pumps to separate the Glycol from the chilled water system.

Case Study

Aqua Seals The Deal With Retro-Fit Free Cooling

For a client running air cooled chiller units to feed their injection moulding hall, the simple addition of a bolt-on Free Cooler to their existing cooling system is forecast to save them over £34,000 in energy costs every year. Our London based client specialises in producing seals and sealing solutions. Which are used in the fluid power industry worldwide. Their production facility runs 24/7, so it’s essential that any system downtime is kept to an absolute minimum.

The benefit of adding Free Cooling into a system is that overall power, or energy use, is greatly reduced. Because the lower ambient air temperature is used to cool the process return water wherever possible, the need for mechanical cooling is much less. In addition, by reducing the running time of the equipment you automatically extend its lifetime and lower lifetime maintenance costs. You also gain built in redundancy – if your chiller fails the Free Cooling side can still operate. The technology within the Free Cooling unit senses both the return fluid temperature and the ambient air temperature. When the ambient is lower than the return water temperature, the fluid is passed through a coil that exchanges the heat in the fluid to the ambient air, using just the mechanical effect required to drive the fans to pull the air through.
