Improve your existing temperature control equipment to reduce energy costs and carbon emissions, extend plant life and mitigate breakdown risk with our eMission Critical solutions. We can conduct no-obligation energy analysis audits and consultation to illustrate the best opportunities to improve energy efficiency whether through free cooling, heat recovery or efficiency improvements such as adiabatic enhancements or variable speed drives.

We provide data to show how efficiently your equipment is operating and recommend ways it can be improved with expected payback periods.

We can offer a number of solutions to enhance your existing temperature control equipment, with data to back up our recommendations.


Free Cooling projects can save up to 80% of temperature control energy costs.  In much of Western Europe, the relatively cool climate allows for partial or full free cooling for much of the year with substantial energy savings between October and April.

Any externally sited chiller can benefit from free cooling. This can be in the form of partial free cooling (where the chiller’s compressors are still doing some of the work to cool) to full free cooling (where the full load on the chiller is offset). In contrast, an externally sited chiller’s compressors with no free cooling capabilities will be working flat out to achieve the same.



Free heating can be achieved by recovering the “waste” heat from cooling processes.  Where heating or hot water is required for process or domestic use on the same site as cooling requirements, then systems can be created or retrofitted to utilise heat rejected from cooling to reduce or even remove the need for fossil fuel heating.  Heat pumps are classed as a renewable energy and can improve TER from 1.5 to 9 giving up to 600% potential efficiency gains.  Why waste “waste heat”?

Recycling waste heat from your cooling systems will help to increase the efficiency of your plant.  The waste heat that would have been rejected to the atmosphere, is recovered and reused for any number of process needs including heating or preheating water to use for either domestic hot water or process applications.



Available for new and existing equipment, an adiabatic enhancement is a unique system that improves the performance, reliability, and energy efficiency of all air-cooled equipment, without requiring energy to provide its cooling effect.  The adiabatic enhancement works by reducing the temperature of the ambient air by as much as 20°C. A reduction of 10°C alone can generate a 13% reduction in energy consumption – delivering immediate cost savings and environmental benefits.



Controlling the flow of air and water in process temperature control systems is an effective, permanent way to meet the everchanging demands put on a system and enhance its efficiency. 

ICS Cool Energy can install a Variable Speed Drive or VSD (an electrical/electronic system that provides infinitely variable speed control of AC induction motors).  VSD’s can be installed to meet varying system flow rate requirements or just to increase energy efficiency.  Payback on an installed system can be as little as 6 months.



Can you audit our energy usage and make recommendations?

No, we refurbish all makes and models of chillers and TCUs.

How can I improve the energy efficiency of my chiller?

There are many ways to make retrospective energy-enhancing improvements to your temperature control equipment, including free cooling, heat recovery, adiabatic enhancement, variable speed frequency drives for pumps and fans and compressor upgrades.

What is Free Cooling?

Free cooling uses the external ambient air temperature to fully or partially take load off the compressor reducing the power consumption of the overall temperature control system

What is heat recovery?

Heat pump chillers can redirect the waste heat from refrigeration processes to recover the energy by fully or partially delivering hot water requirements thus reducing the power consumption of separate heating and cooling systems.

What are the benefits of energy enhancements?

As well as reducing energy and maintenance costs, energy enhancements can extend the life of your equipment, improve plant operations, reduce carbon footprint, comply with legislative requirements and improve safety.
