Free Cooling For ICS Customers
 
What is free cooling?

Free cooling

Free cooling is where you utilise the low outside air temperature for chilling water in your process or air conditioning, rather than part or all of your air-cooled chiller plant.

ICS Customers are now installing free cooling units such as chillers with integral free cooling coils or dry air blast coolers in line with their existing cooling system.

When the ambient air drops to a set temperature - a modulating valve allows all or part of the chilled water to by-pass your existing chiller and run through the free cooling system, which uses less power and utilises the lower ambient air to cool the water in your system. See below to see how this works.

ICS can install and modify your system to your exact site requirements. Please contact us for further information.

What are the benefits?
You can utilise the cold air outside which is free.
You would reduce the running use of your existing compressors.
There would be less wear and tear due to the reduced hours of operation.
It would extend the life expectancy of your existing equipment.
Your power costs would reduce.
Your free cooling system could run automatically when required.
Payback for a new system could be as little as 12 months.
Lower cost start up for Free Cooling
Free cooling chiller

If you have an existing chiller, then ICS can provide a dry air blast cooler to run in-line with your system to give you all of the Free Cooling benefits.

ICS has a wide range of dry air blast coolers to suit your particular duty and site requirements. Each can be fitted with a control panel to regulate the free cooling system and to allow the maximum cost savings for you or your clients’ business.

Interest-free loans for businesses
Industrial cooling equipment

If you are looking to buy equipment to save energy and money, then there is an independent organisation called the Carbon Trust and they can help you apply for an Energy-Efficiency Loan.

What are energy-efficient loans?

The loans are part of a £10 million government backed initiative. The interest-free loans of between £5,000 and £100,000 are available to qualifying small and medium sized enterprises looking to invest capital in energy saving projects. The loans are repaid over a period of up to 4 years.

Call their HELPLINE on 0800-085 2005 for further information or, alternatively, Kay Richards on 0870 190 6236, who will be able to take you through the loan process.

Why should you be interested?

Free cooling systems

Energy efficiency makes sound economic sense – especially in view of the recent rises in the cost of electricity. When upgrading existing equipment even the modest investment in energy saving equipment can save a company over 20% on energy bills. In favourable cases the amount of money saved each month will exceed the loan repayments thereby increasing company profits by hundreds, or thousands, of pounds each year throughout the payback period. Thereafter the full value of the saving contributes to the bottom line.

These loans are unsecured and intended to reduce the barrier of investment by providing access to capital on very favourable terms:

Completely interest-free.
Repayment period of up to four years.
No arrangement fees.
 
Operation in Summer   Operation in mid season   Operation in winter
The video below shows that in summer the chiller acts in the same way as a traditional electric chiller, meaning the compressors are running. Click to view full size demo.
The video below shows that in the mid season it is possible to reduce the operation of the compressor thanks to the water pre-cooling in the free-cooling coil. Click to view full size demo.
The video below shows that in winter operation the water is completely chilled in the freecooling coil, thus keeping electric energy consumption to a minimum. Click to view full size demo.
