Bristol-based cooling specialist, Cool-Therm, has announced that it has installed a new Turbomiser chiller at a flexible packaging manufacturer in order to maximise energy savings.
CoolTherm states the new, high-efficiency Turbomiser chiller, installed at Amcor Flexibles Winterbourne, operates on virtually frictionless magnetic bearings, to deliver lower power consumption and reduced carbon emissions.
It is believed to be the first chiller of its kind to be installed in the packaging sector.
During the project, Cool-Therm worked closely with staff at Amcor to replace one of the existing chillers at the site, after it had reached the end of its operational life.
Cool-Therm has worked with Amcor Flexibles Winterbourne for more than 20 years, installing and servicing three large chillers delivering the continuous chilled water required by the plant’s plastics extrusion machines.
Cool-Therm states the new Turbomiser chiller, installed alongside two existing McQuay centrifugal chillers, operates around the clock, all year round, maximising savings.
Andreij Duma, Operations Director at Amcor Flexibles Winterbourne, said: “Cool-Therm anticipated a 20 to 25 percent energy saving with the introduction of Turbomiser. However, the performance over the first six months looks even better than this, and the latest figures show a saving of just under 50 percent.”
Ken Strong, Managing Director of Cool-Therm, explained: “The period of use so far covers the warm season. We would expect even better efficiency still during winter. Here, Turbomiser can operate at lower condensing temperatures where the efficiency advantages are greatest.”
The ‘sweet spot’ for Turbomiser is considered to be 25 to 60 percent of load, where, due to its operating characteristics versus conventional chillers, energy efficiency for the delivered cooling capacity is maximised. Turbomiser is equipped with integral inverter drives, enabling very fine incremental adjustments to be made to precisely match chiller output to cooling load.
Cool-Therm states it is now working to fine-tune the cooling system to deliver further energy savings to customers.
