IsoCool blast cooling costs by 50%


Carclo Technical Plastics

International plastics manufacturer, Carclo Technical Plastics, is set to reduce the operating costs of its chilled water system at the Mitcham site by almost 50% due to an energy saving solution from process cooling specialists, IsoCool Ltd. The retro-fit of a separate air blast cooler to an existing chiller system back in May 2009 has been a worthwhile investment: IsoCool’s system will have paid for itself in just over two years.

Carclo Technical Plastics utilise cutting edge technologies to supply clients in the medical, optics, and electronics applications industries. They realised, however, that the chiller system in their injection moulding process was in need of updating. Operations Director Ian Hood explains why they chose IsoCool:

“As well as having a great reputation and sharing our commitment to the environment, IsoCool are also focused on the bottom line. They provided us with a detailed proposal that included a payback schedule so we knew from the outset what savings we would make.”

The air blast cooler installed by IsoCool provides a cooling source during times of the year when the ambient will allow partial and up to 100% direct air cooling. This offloads the chiller and its associated high running costs. The air blast cooler becomes more effective as the air temperature drops, eventually leading to the compressors switching off altogether.

Ian Hood is delighted with the outcome so far:

“We operate on partial free cooling when the ambient is between 11.5oC and 16.5oC. At 11oC and below we function entirely on free cooling”.

He adds: “Carclo operates in fast growing, dynamic markets so our manufacturing process has to run like clockwork. IsoCool’s professional installation exceeded our expectations – there was no disruption at all. I’d have no hesitation in recommending them to any manufacturer who wants to reduce energy and cost consumption”.
