Features and Benefits Reliability • The Trane helical rotary compressor is a proven design resulting from years of research and thousands of test hours, including extensive testing under extraordinarily severe operating conditions. • Trane is the world’s largest manufacturer of large helical rotary compressors, with more than 240,000 compressors installed worldwide.
PAGE 5
Features and Benefits Application Versatility RLC-PRC029-EN • Industrial/low temperature process cooling – Excellent operating temperature range and precise control capabilities enable tight control with single chiller or series configuration.
PAGE 6
Features and Benefits Simple, Economical Installation 6 • All units fit through standard double-width doors and most units fit through single width doors. Units are designed with bolt-together construction for disassembly to fit through smaller openings. • Small footprint saves valuable equipment room space and alleviates access concerns for most retrofit jobs. • Lightweight design simplifies rigging requirements, further reducing installation time requirements and costs.
PAGE 7
Features and Benefits Precision Control RLC-PRC029-EN • Microprocessor-based Trane CH530 controls monitor and maintain optimal operation of the chiller and its associated sensors, actuators, relays, and switches, all of which are factoryassembled and extensively tested. • Easy interface with computers hosting LonTalk/Tracer Summit/BACnet building automation/ energy management systems allows the operator to efficiently optimize comfort system performance and minimize operating costs.

Application Considerations Condenser Water Temperatures With the model RTWD chiller, condenser head pressure control is necessary only if the unit starts with entering condenser water temperatures below 55°F (12.8°C), or between 45°F (7.2°C) and 55°F (12.8°C), when a temperature increase of 1°F (0.56°C) per minute to 55°F (12.8°C) is not possible.
PAGE 9
Application Considerations For variable primary flow applications, the rate of chilled water flow change should not exceed 10 percent of design per minute to maintain +/-0.5°F (0.28°C) leaving evaporator temperature control. For applications in which system energy savings is most important and tight temperature control is classified as +/-2°F (1.1°C), up to 30 percent change in flow per minute are possible.
PAGE 10
Application Considerations Heat Recovery At a time when energy costs are high and continue to rise, reducing energy usage has become increasingly important. By using a RTWD chiller with heat recovery, utilization of energy can be improved by using heat from the condenser that would otherwise be wasted. The use of heat recovery should be considered in any building with simultaneous heating and cooling requirements or in facilities where heat can be stored and used at a later time.
PAGE 11
Application Considerations Acoustic Considerations For chiller sound ratings, installation tips, and considerations on chiller location, pipe isolation, etc., refer to the Water-Cooled Series R Chillers Sound Ratings and Installation Guide. Remote Condenser The installation of a split system offers a good economic alternative to satisfy the chilled water demand for cooling a building, particularly in the case of new construction.

Mechanical Specifications General Exposed metal surfaces are painted with air-dry beige, direct-to-metal, single-component paint. RTWD units ship with full operating charges of refrigerant and oil. RTUD units ship with a full operating charge of oil and a nitrogen holding charge. Molded elastomeric isolation pads are supplied for placement under all support points. Trane air-cooled condenser structural elements and fan sections are galvanized steel.
PAGE 133
Mechanical Specifications Condenser (RTWD only) Dual circuited, shell and tube condenser designed with seamless internally/externally finned tubes expanded into tubesheets and mechanically fastened to tube supports. Condenser tubes are 1.0 inch (25.4 mm) diameter on standard efficiency chillers and 0.75 inch (19.05 mm) diameter on high and premium efficiency chillers. All tubes can be individually replaced. Shells and tube sheets are made of carbon steel.
PAGE 134
Mechanical Specifications The panel includes machine protection shutdown requiring manual reset for the following conditions: • Low evaporator refrigerant temperature and pressure • High condenser refrigerant pressure • Low oil flow • Critical sensor or detection circuit faults • Motor current overload • High compressor discharge temperature • Lost communication between modules • Electrical distribution faults: phase loss, phase imbalance, or phase reversal • External and local emergency s

Options All necessary settings and setpoints are programmed into the microprocessor-based controller via the operator interface. The controller is capable of receiving signals simultaneously from a variety of control sources, in any combination, and priority order of control sources can be programmed. The control source with priority determines active setpoints via the signal it sends to the control panel.
PAGE 136
Options Insulation for High Humidity The evaporator and water boxes are covered with factory installed 1.5 inch (38.1 mm) insulation. Factory installed foam insulation is used on the motor housing, suction line, liquid level sensor, and oil return system assembly (with its associated piping). Isolators Molded elastomeric isolators ship with the unit. Low-Temperature Evaporator Optimized compressors and oil cooler enable evaporator operation down to minimum leaving water temperature of 10°F (-12.2°C).
PAGE 137
Options Non-Fused Disconnect A non-fused molded case disconnect switch, factory pre-wired with terminal block power connections and equipped with a lockable external operator handle, is available to disconnect the chiller from main power. Dual Point Power Connection Unit is available with either dual or single point power connections. Under/Over-Voltage Protection Unit receives protection against variations in voltage (current lag and spike protection is standard).
PAGE 138
Options LonTalk/Tracer Summit Interface LonTalk (LCI-C) or Tracer Summit communications capabilities are available, with communication link via single twisted-pair wiring to factory-installed, tested communication board. Low Ambient Fan Control - Two Speed (RTUD only) The fan control shall provide for the first fan to be a two speed fan and the microprocessor can be programmed to control the low and high speed of that fan.
