Series R RTHD No Background

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

As a heat pump chiller, the RTWD features 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 Controller serves 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

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 Controller enhances equipment performance and enables 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
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

RTWD (80-250 tons; 600-3,000 MBH)

As a heat pump chiller, the RTWD features expanded heating capabilities of up to 165° F (74° C) for boiler replacement in a wider range of applications with refrigerant R-515B
R-513A refrigerant utilized for both comfort cooling and low-temperature industrial applications, with leaving evaporator solution temperatures as low as 10° F (-12° C)

RTHD (175-400 tons; 2,100-5,000 MBH)

R-513A refrigerant utilized for all applications
The RTHD chiller can be configured to produce leaving evaporator solution temperatures as low as 5° F (-15° C) for industrial process cooling applications
The RTHD chiller can generate condenser water temperatures as high as 111° F (44° C)
