Cooling costs cut

Technical plastic injection moulder, OGM, has invested in an energysaving product for the process cooling system in its new Yarnton factory. Made by IsoCool, the IsoFC is a packaged heat exchanger for use within dual circuit systems. It is on target to reduce cooling costs by over 25%, giving payback in just 2.5 years.

IsoCool installed a Eurochiller AX-A chiller with cooling capacity of 110kW, a pump and tank system, and bespoke pipework and used existing equipment where possible.

This included an air blast cooler, which IsoCool realised could be used in conjunction with the IsoFC to optimise energy savings.

The IsoFC indirectly links mould and hydraulic cooling circuits through a high-efficiency packaged heat exchanger, and facilitates energy transfer via intelligent software between systems without them mixing.

During low ambient conditions it is designed to use the surplus capacity from the air blast cooler to pre-cool water returning from the mould circuit before it reaches the refrigeration plant. Both circuits fulfil their main functions, and the load on the chiller is greatly reduced.
