For over 35 years, ICS Cool Energy have been providing technical advice and solutions to leading manufacturers world-wide, helping them to meet compliance, improve their product quality and cycle times whilst reducing their energy consumption and operative costs.




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

ICS Cool Energy can install a Variable Speed Drive (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 5 months.

We can retrofit variable speed drives, where smaller pumps are fitted. These pumps are all in one with the pump, motor and frequency drive combined giving greater flexibility and a factoryinstallation look. For horizontal pumps, installation is much faster with less disturbance, meaning less process down time. Vertical pumps sometimes require some system modifications and pipework to accommodate.

Benefits of variable speed drives (VSD’s)

  • 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 conditions.

Free Cooling works with either a chiller with a built-in free cooling coil or a free cooler working in series with a chiller. The latter is more efficient, due to the larger surface area provided by the free cooler. System design will largely depend on your cooling demands and the footprint of your site.

Cooling equipment will need to be cited externally to take advantage of the cooler ambient temperatures.

When the ambient air temperature drops below the process fluid return temperature, a 3-way valve diverts the returning process fluid. This goes through the free cooling coil in which the cooler ambient air removes heat and cools the returning fluid.


The iFH (Free Heating) products available from ICS Cool Energy harness the rejected energy from a process or HVAC circuit & utilise it to assist in the generation of low temperature hot water up to 80°C.

As a result, it reduces the energy consumption of the cooling source & maximises the energy efficiency of both a site’s heating & cooling circuits.

If you have a process that needs heating, this heat can be recovered from the chiller via our i-FH unit and then supplied directly to your boiler, reducing the heating load and drive down energy costs as a result.



ICSLink is a remote telemetry system that collects performance data from your asset, transmitting it through its’ web interface, which is supported by all mainstream browsers, or through its’ mobile app. So you’ll have 100% visibility of your data 24/7, wherever you are!

With the industry leader in remote monitoring equipment, it utilises the latest solid-state technology with no moving parts and incorporates internal watchdogs for mutual performance verification and reliability.

ICSLink can be fitted to a huge range of new and legacy temperature equipment, rented or owned, and will fit within your existing building management system.


For national, multi-site operations, facilities management providers or any business needing to manage multiple temperature control equipment assets, ICS Cool Energy can help.

Our asset management services include enhanced condition-based reporting, enhanced regular updates on site activities, critical risk-based site contingency planning, energy audits, advice and bespoke SLA’s. We take care of everything to keep your industry running.


We deliver efficiency gains by applying our industry leading system knowledge to virtually every aspect of chiller plant operations.

Why audit? 

You will get charts showing the measurement results, analysis of the measurements and a proposition of enhancements to the chiller.

What will we measure?

  • Chiller cooling capacity & power input
  • Chilled water leaving & entering water temperatures
  • Ambient temperature
  • Audit Case – developed specifically to audit chillers
  • Data measured and logged typically over a two-week period

Benefits of a chiller energy audit?

  • Get information about the real operation of your chillers.
  • Learn how to improve your chiller’s performance with a calculation based on measured data.
  • Detect opportunities to improve the current operation.



When your process downtime is not an option, secure your process cooling or heating supply by having ICS Cool Energy deliver a full contingency plan agreement. We will arrange a full site survey to plan everything required in advance to minimise downtime.

The fastest way to ensure an uninterruptable supply is to leverage our national team of service and installation engineers and over £50m of rental cooling and heating equipment complete with all ancillaries needed including electrical cables, hoses, heat exchangers, pumps, Fan Coils and AHU equipment.

Risk mitigation and contingency planning is ideal for industries that have critical processes including, plastics, healthcare, food, beverage, chemical, pharmaceutical, manufacturing, data centres and HVAC.

Be prepared when the unexpected happens and keep your operations up and running with a contingency plan. Our experienced team will work with you to build a plan and prepare your facility to mitigate risks and minimise downtime. Plans may include adding extra valves & pipework into your existing installation to allow a rental unit to be added quickly when needed. We have choices when it comes to the equipment needed.

Have you had problems with water treatment or have an ongoing requirement to correct poor quality fluid in your system? Filtration of a water circuit offers a permanent and ongoing solution for controlling the water quality of your critical system.

Our permanently installed system removes debris and particulate from the fluid system that would otherwise build up leading to potential failure of fluid circuit components (Evaporators, condensers, heat exchangers, pump seals or shafts, valves etc.). Poor water quality also serves to lower the efficiency of your cooling or heating plant through losses in heat exchange capabilities.


The only contents within a refrigerant system should be refrigerant and oil. Modern polyester oils are very hydroscopic. Every time intrusive work is carried out,
moisture is inadvertently allowed to enter the system.

Moisture mixed with polyester oil turns into acid, which leads to system degradation and component failures. Acid attacks the electrical insulation within compressor motor windings – eventually leading to an electrical compressor failure or what is commonly called a “burn-out”.

ICS Cool Energy can analyse the oil within your
refrigeration circuit to identify early signs of potential failure, noting moisture, acid and metallurgy. We will then make recommendations in line with the results.



Scroll and screw chillers can be retrofitted with an upgraded control system, giving more accurate control as well as the ability to add remote monitoring through ICS Link or local BMS systems.

Intelligent services also mean the possibility of remote service visits and enhanced diagnostic capability over any previously installed outdated systems. Retrofitting a new controller can prolong the lifespan of your chiller.


We offer a wide range of next generation low
GWP (global warming potential) or No ODP
(ozone depletion) refrigerant blends, specifically manufactured to lower your carbon footprint and with sustainability and the environment at the forefront.


Cleaning up a contaminated system with traditional solvents is a risk, with our Ref Cleanse system we can recycle the recovered refrigerant (removing any contaminates) as well clean the refrigerant
system and leaving the system immaculately clean.

Our highly qualified engineers utilise our Ref Cleanse system which provides a cascade, triple filtration process. The system components are segregated, and refrigerant flushed through each area.

It works by using refrigerant to clean the system, lifting out oil which holds acid and carbon and leaves a system clean and as reliable as it should be. Our system allows us to work on circuits up to 40kg of
refrigerant charge.

All contaminates including oil, carbon, debris, sludge, and any trace of moisture are completely removed from the circuit which is returned to an “as new” status.

Additionally, we can recycle contaminated refrigerant that would normally have to be disposed of, reducing impact on the environment, and creating considerable savings.

Benefits of ref cleanse

  • Extended lifecycle of equipment.
  • Prevent expensive component failures.
  • Avoids costly virgin refrigerant through recyling.
  • No need to use inferior solvents or cleaning agents.
  • System is quickly returned to full operating performance and efficiency.
