A WEEK after announcing the introduction of a chiller to run on the new HFO refrigerants, the developers have withdrawn the product pending 'further development work'.
Klima-Therm and Cool-Therm the developers of the Turbomiser chiller, came in for criticism from Danfoss Turbocor who maintained that their compressor, which is used in the Turbomiser product, had not been verified for use with HFO refrigerants.

A spokesman for the chiller developers last night said: 'We believe that HFO refrigerants show great promise for the future and could meet the pressing need for an in-kind, low GWP alternative to HFC refrigerants. However, following discussions with Geoclima Srl and Danfoss Turbocor, we accept that further development work and testing are required before these products can be introduced to the market.'

'We will continue our research and development activities with these new refrigerants, and plan to offer an HFO-based Turbomiser chiller to the market when it is fully qualified through our supply chain.'
