Unique and innovative sustainability features

Trane XStream heat pumps are a smart alternative to traditional boilers with features to effectively address the needs of geothermal and district heating applications:
• Compressors specially designed for high temperature applications
• Large capacities up to 2020 kW (at Eurovent Air Conditioning heating conditions)
• High condensing water temperatures of up to 85°C (RTWF G) allowing operation as a high temperature heat
pump or a high condensing temperature cooling system.
• High performance up to 4.8 COP (at Eurovent Air Conditioning heating conditions)
• Operates down to 10% part load requirements.

Extreme versatility

Whether you have seasonal comfort requirements or a sensitive industrial application there is a model from the XStream range that will satisfy your needs.

For even greater system efficiency, Trane XStream units are fully compatible with:
• Multiple compressor design
• Series chiller arrangements
• Variable Primary Flow (VPF) applications
• Screw Compressors with Variable Volume Index (Variable Vi)

Geothermal applications

The technologies built into Trane’s XStream series heat pumps make them ideally suited to geothermal applications.

  • Heating: from -12 to 28°C (20°C with R134a and R513A) on the evaporator side and up to 85°C (68°C with R134a and R513A) on the condenser side

  • RTWF packaged chillers are available in 81 different models with three refrigerants and three efficiency levels: SE: Standard Efficiency, HE: High Efficiency, HSE (With AFD): High seasonal efficiency.

  • RTWF G: R1234ze — RTWF: R134a/R513A
