Free cooling chillers

Free Cooling allows businesses to recover up to 80% of their process cooling energy costs by utilising lower ambient temperatures to cool their process application and reducing the need to power the chiller. Available as independent units or integrated with your process chiller, free coolers can be retrofitted into your existing process or installed as part of a turnkey solution.

Working with businesses in the manufacturing and facilities management industries, we have lowered their energy costs and reduced their environmental impact through free cooling systems.

Given the intrinsically process-heavy nature of the UK’s industrial manufacturing, process cooling is one of the biggest costs incurred. For many industrial end-users, process cooling is achieved solely via an air or water-cooled chiller or cooling tower.

However, all industrial applications with a water leaving temperature of 10°C or more – regardless of sector – can start to be cooled via the external ambient air temperature, rather than by electro-mechanical refrigeration, thanks to a process known as free cooling.

Up to 80% energy savings
One of the stand-out benefits of a free cooling system is the sheer amount of energy – and therefore utility bills – it can save. While free cooling can bring about a reduction in energy consumption for any process cooling application with a water leaving temperature of 10°C or more, it should be attractive to larger manufacturers, such as those working in the chemical and pharmaceutical sectors.

Further costs can be saved due to the reduced load on the chiller – particularly the compressors and fans – as they are not worked as hard, or at all in some cases. As such, maintenance costs can be lower over the lifetime of the system. From a health and safety point of view, unlike cooling towers, free cooling systems pose no risk of legionella and therefore do not require additional water treatment costs beyond the norm to mitigate the risk of an outbreak.

Free Cooling FAQ's

What temperature is free cooling?

Partial free cooling can be achieved as soon as the ambient air temperature is 1°C below the process return temperature; while full free cooling can be achieved when the ambient air temperature is around 5°C below the process supply fluid temperature.

What are the benefits of free cooling?

Free cooling will reduce mechanical energy consumption, improved carbon footprint, reduce load on mechanical parts & therefore reduce maintenance cost and extend life of equipment, smaller load demands can lessen the depreciation value of the chiller over its lifetime, It is easy to retrofit (space permitting) and payback for any new equipment can be quick.

Is there a way to benefit from free cooling with no need for capital investment?

ICS Cool Energy offer the FLEX program, comprising a monthly package which provides you with running cost reductions versus your existing plant running costs. This long-term solution is a fixed, hard-piped install to your process, offering energy savings, maintenance and annual cooling circuit fluid analysis and the option to upgrade as technologies improve. This minimum 5 year contract option is the answer if capital investment is not available and can be paid in monthly or quarterly rental payments.

How does free cooling work?

It works by incorporating a heat exchanger that allows the circulating coolant to be cooled directly by the ambient air, eliminating or reducing the need for compressor operation.

Are free cooling chillers more expensive than traditional chillers?

Free cooling chillers may have a higher upfront cost compared to traditional chillers. However, the energy savings and reduced operating costs over time typically offset the initial investment, making them more cost-effective in the long run.

Can a free cooling chiller be integrated into an existing cooling system?

Yes, free cooling chillers can be integrated into existing cooling systems. However, it is crucial to assess the compatibility and requirements of the existing system and consult with a professional to ensure a successful integration.

Process chillers

Process chillers are designed and built from the ground up to be more reliable, operate within tighter specified tolerances and to be more robust for continued operation when compared to chillers designed for HVAC. Our i-Chillers are specifically designed to cope with the rigours of manufacturing and critical processes. Process chillers may cost slightly more than equivalent HVAC or comfort chillers but are significantly better value and fit for purpose in a critical process. A process chiller will deliver more accurate leaving water temperature, operate trouble free for longer, have a lower op-ex cost and a greater residual value. <strong>Chillers built for process</strong> Our range of process chillers is designed specifically for process, with features such as unique finned coil evaporators immersed inside the cold-water tank, making them less susceptible to freezing and able to cope with variable load and process fluctuations. The large integrated cold side buffer tank enables closer temperature control for process tolerance and reduces wear and tear from compressor start and stop operations. i-Chillers have high-pressure pumps as standard to cope with the more complex pipework found in process applications. Being fully enclosed in robust steel panels not only protects but creates a smaller footprint for ease of access and plug & play installation. <strong>Our approach</strong> Since 1989 we have created bespoke temperature control solutions across all manufacturing, industrial and critical process applications. With a network of highly experienced technical engineers nationwide, we will visit your site to understand your exact application needs and audit your facilities and potential constraints to develop the optimum solution for your circumstances. We can design, install, commission and project manage bespoke turnkey solutions and provide full, tailored 24/7 maintenance & breakdown support with our nationwide service & hire team.
