Trane has extended its XStream range of water-cooled screw chillers, with the RTHF G units now available across Europe, the Middle East and Africa.
 
Jose La Loggia, vice president and general manager of Trane in Europe, said: “RTHF G units address the needs of building owners who want to increase the sustainability of their operations, while maintaining or improving capacity, efficiency and reliability with critical, large capacity cooling installations.''
Trane says the new design offers customers an alternative, cost-effective option for reducing greenhouse gas emissions, because the units operate with R1234ze refrigerant. 
 
The new units are said to feature the largest screw compressors on the market, which when used in a double circuit deliver capacity of up to 2700 kW and benefit most commercial and industrial cooling applications that require maximum performance and sustainability within a limited installation space. The XStream RTHF G claims high-efficiency performance with up to 6.3 Energy Efficiency Ratio (EER) and up to 9.5 European Seasonal Energy Efficiency Ratio (ESEER) with variable speed.

Trane says key features include:
  • Dual circuit configuration in a market segment that could previously only use single circuit centrifugal chillers. Dual circuit configuration reduces refrigerant content per circuit and further increases reliability
  • Serial counterflow design compatible with the use of variable primary flow used for the first time in a screw compressor chiller and allowing for a greater efficiency.
