Circlemiser chiller targets data centre needs with UK launch

Klima-Therm claims new heat exchanger design can meet cooling needs in more confined environments

Klima-Therm hopes the launch of the Circlemiser chiller technology in the UK will allow it to target significant potential among premises that are restricted in terms of space for housing cooling solutions, such as data centres, offices and commercial buildings.

Developed and manufactured by Geoclima, Circlemiser is a dry air-cooled chiller device intended to offer improved efficiency through the use of a revised heat exchanger design that replaces traditional flat coils with cylindrical condensers.  The technology is also designed to use flooded evaporators in a cascade system as part of efforts to improve operational performance and meet energy efficiency targets.

“By packing more active heat exchange surface into a given space, the heat exchange capacity of Circlemiser’s new cylindrical microchannel condensers is increased by 45% compared with traditional condensers,” Klima-Therm claimed in a statement.

Company Director Tim Mitchell said that the key UK opportunities for the Circlemiser chiller technology were seen in commercial spaces and data centres.  Mitchell said these are typically properties that require high cooling loads to remove heat from a certain space in sometimes restrictive or confined areas.

“We see big opportunities for Circlemiser in refurbishment projects, where cooling loads may have increased over time and the existing chiller is now under-sized, but where plant space is restricted and unable accommodate a larger replacement,” he said. “We often meet this, particularly in London, where plant room and roof-top real estate is at an absolute premium.”

Mitchell claimed that the chiller’s release in the UK sought to tackle demand for a cooling solution that can function in compact spaces, while curbing the extra expense and increased maintenance needs associated with adiabatic systems.

According to Klima-Therm, the Circlemiser range is available with both R134a and the ultra-low Global Warming Potential (GWP) refrigerant HFO-1234ze.
