Series R® Helical Rotary Screw Chillers

Two proven, modernized workhorses that offer reliability and provide application flexibility — helping building owners meet their sustainability goals.

  • RTWD chiller heat pumps feature expanded heating capabilities of up to 165° F (74° C) for boiler replacement in a wider range of applications
  • RTHD can be configured to produce leaving evaporator solution temperatures as low as 5° F (-15° C) for industrial process cooling applications
  • Symbio® 800 Equipment Controllers serve as the launch point to connect to an array of Trane building systems and services
  • Series R chillers utilize R-513A refrigerant for cooling and R-515B for heating, offering a 55% reduction in GWP compared to R-134a

FEATURES & BENEFITS

  • Outstanding versatility for a wide range of demands

    Series R helical rotary chillers are suited for commercial applications that require precise temperature control. Their wide operating temperature range, electronic expansion valve and short anti-recycle timers give them the flexibility for almost any high-performance cooling and heating system. 

  • Environmentally friendly refrigerants and updated controls

    Series R helical rotary chillers help customers meet sustainability goals with low-GWP refrigerants, including R-513A for cooling and R-515B for heating, offering a 55% reduction in GWP compared to R-134a. Symbio controllers integrate with building automation systems and assist with performing various energy efficiency and chiller performance analyses, delivering insights on enhancement opportunities.

  • A reliable, proven solution

    Series R helical rotary chillers offer high reliability and enhanced energy efficiency due to their direct-drive compressor design that uses fewer moving parts than gear compressors.

  • Compact size for easier installation

    Chiller replacement can be faster, cheaper and less disruptive due to the Series R chiller’s compact size, which fits into most existing mechanical rooms without requiring additional floor space or wall tear-outs. Units can pass through a standard double door opening, and both single- and dual-point power connections can take advantage of existing wiring.

  • Symbio 800 Controllers enhance equipment performance and enable wireless options for improved connectivity
  • Accelerated life testing simulates thousands of hours of operation on the compressor, the heart of the RTWD and RTHD chiller
  • Comprehensive Applied Heating Solutions help offer flexible design options enabled by Trane controls to meet a variety of application needs
  • Falling film evaporator in the Series R chiller features a Trane patented design that requires less refrigerant
  • Robust helical rotary compressor design has fewer moving parts with premium bearings for superior alignment tolerance and overall reliability
  • Tracer® SC+ building automation system features pre-engineered chiller plant control, enhancing the rotation, staging and sequencing of multiple units to meet dynamic building loads
