Energy Enhancements

Improve your existing temperature control equipment to reduce energy costs, reduce carbon emissions, extend plant life and mitigate breakdown risk. ICS Cool Energy 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 efficient your equipment is operating and recommend ways it can be improved with expected payback periods.

Energy Enhancements

There are many benefits to improving existing temperature control equipment.

  • Improve energy efficiency
  • Reduce maintenance as well as energy bills
  • Extend equipment life
  • Mitigate breakdown risk
  • Improve plant operation
  • Reduce carbon footprint
  • Improve Corporate Social Responsibility profile
  • Improve safety
  • Legislation compliance

ICS Cool Energy offers no-obligation on-site consultation and energy analysis audits.  Our experienced engineers will provide data to show how efficient your equipment is operating and will recommend how it can be improved with expected payback periods.

Free Cooling

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.

When the ambient air temperature drops just 1°C below the process fluid return temperature, a 3-way valve diverts the returning process fluid through the free cooling coil in which the cooler ambient air removes process heat and cools the returning fluid (partial free cooling), it then flows through the chiller’s evaporator where the required set point temperatures are achieved – easing the demand on your chiller’s components and extending their operational life. As the ambient air temperature continues to fall, the amount of process heat taken out of the process fluid by the air increases, progressively reducing the load on the chiller. At 5°C below the process supply fluid temperature, all the process heat is removed by the ambient air in the free cooler – providing full 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.

Heat Recovery

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.


  • Recover up to 70% of potentially wasted electrical heat energy
  • Produce hot water up to 70°C
  • Reduce energy consumption of your heating system(s)
  • No increase in footprint

Adiabatic Enhancements

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.


  • Reduction of system energy input
  • Delivery of additional capacity for your process needs
  • Delivery of design capacity without interruptions, even in higher ambient conditions
  • Extension of equipment operating range beyond its original specifications
  • Improved equipment lifecycle
  • Filters air

Variable Speed Frequency Drives (VSD)

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.


  • Energy savings
  • Cost savings
  • Trouble-free operation
  • Meet system demands more easily
