Danfoss Turbocor has clashed with the developers of the Turbomiser chiller over their use of HFO refrigerants
Danfoss Turbocor has stated categorically that it does not endorse use of HFO refrigerants with its Turbocor compressor . The firm was reacting to the news that the team behind the Turbomiser chiller - which utilises the Turbocor compressor - announced that it had started receiving orders for their chiller which runs on HFO-1234ze.
Speaking from the AHR Expo in Las Vegas, US-based Danfoss Turbocor Corp countered: “DTC does not offer our products with HFO refrigerants and would not warrant the use of our products in this application.”
A joint statement from Cool-therm and Klimatherm, UK distributors of the Turbomiser said: ” We have received orders for a number of HFO-based Turbomiser chillers from UK clients keen to adopt low GWP refrigerants. The chillers are currently being manufactured with tests expected to be completed shortly. They will be operating on HFO-1234ze, which has a GWP of 6.
Their spokesman added: “We understand that Danfoss Turbocor has not yet given an official green light for use of HFOs with Turbocor. However, this is a rapidly developing area, and there is sometimes a lag between those pioneering the application of new technology and those carrying out detailed validation. We believe this will follow in the normal course of events, and that HFOs will become established as a long term viable option for the future. Once the benefits are established and proven, HFO chillers will become a mainstream alternative for the future.””
The Turbomiser distributors added: “It is now thought that “HFO-1234yf may not be suitable for use with the current generation of Turbomiser machines, due to the particular properties of the refrigerant. However, development work in this area contin
However, Turbocor has reacted strongly to what it sees as unauthorised adaptation of its products and warned that its compressors are only configured for R-134a. It has made it clear that it does not endorse the Turbomiser alterations and will not cover warranty on any compressor altered to use HFOs.
