Air-Cooled Series R Helical-Rotary Liquid Chiller ™ Model RTAC 120 to 200 (400 to 760kw - 50 Hz) Built for the Industrial and Commercial Markets RLC-PRC005-E4
Introduction The new Trane Model RTAC Air-Cooled Helical-Rotary Chiller is the result of a search for higher reliability, higher energy efficiency, and lower sound levels for today’s environment. In an effort to reduce energy consumed by HVAC equipment and to continually produce chilled water, Trane has developed the Model RTAC chiller with higher efficiencies and a more reliable design than any other air cooled chiller available on the market today.

Features and Benefits Water Chiller Systems Business Unit The Series R™ Helical-Rotary Compressor • Unequaled reliability. The next generation Trane helical-rotary compressor is designed, built, and tested to the same demanding and rugged standards as the Trane scroll compressors, the centrifugal compressors, and the previous generation helical-rotary compressors used in both air- and water-cooled chillers for more than 13 years. • Years of research and testing.
Improved Acoustical Performance Figure 2 Cutaway of a compressor The sound levels of the Series R Model RTAA have been steadily improved since its introduction. With the advent of the Model RTAC, sound levels are reduced significantly by addressing two major sources: the compressor and the refrigerant piping. First, the compressor has been specifically designed to minimize sound generation.
Simple Installation Compact Physical Size The Trane Model RTAC chiller averages a 20 percent reduction in physical footprint, while the greatest change is actually 40 percent smaller when compared against the previous design. This improvement makes the RTAC the smallest air-cooled chiller in the industry and a prime candidate for installations that have space constraints.
Superior Control with Tracer Chiller Controls ™ The End of Nuisance Trip-Outs and Unnecessary Service Calls? The Adaptive Control™ microprocessor system enhances the air-cooled Series R chiller by providing the very latest chiller control technology. With the Adaptive Control microprocessor, unnecessary service calls and unhappy tenants are avoided. The unit does not nuisance-trip or unnecessarily shut down.
Options Premium Efficiency and Performance Option This option provides oversized heat exchangers with two purposes. One, it allows the unit to be more energy efficient. Two, the unit will have enhanced operation in high-ambient conditions. Low-Temperature Brine The hardware and software on the unit are factory set to handle lowtemperature brine applications, typically below 5°C [41°F]. Ice Making The unit controls are factory set to handle ice making for thermal storage applications.
Application Considerations Certain application constraints should be considered when sizing, selecting, and installing Trane air-cooled Series R chillers. Unit and system reliability is often dependent on properly and completely complying with these considerations. When the application varies from the guidelines presented, it should be reviewed with your local Trane sales engineer. Unit Sizing Unit capacities are listed in the performance data section.
Application Considerations Figure 5 — GPM Out of Range 29.4°C 7.6 Lps 15.6°C 2.2 Lps 15.6°C 7.6 Lps CV Pump Load 35°C 5.4 Lps 15°C 5.4 Lps 21°C 7.6 Lps CV Pump 35°C 2.2 Lps 35°C 7.6 Lps Leaving-Water Temperature Range Trane air-cooled Series R chillers have three distinct leaving-water categories: standard, low temperature, and ice making. The standard leaving-solution temperature range is 4.4 to 15.6°C [40 to 60°F]. Low-temperature machines produce leaving-liquid temperatures less than 4.
Application Considerations Variable Flow in the Evaporator An attractive chilled-water system option may be a variable primary flow (VPF) system. VPF systems present building owners with several costsaving benefits that are directly related to the pumps. The most obvious cost savings result from eliminating the secondary distribution pump, which in turn avoids the expense incurred with the associated piping connections (material, labor), electrical service, and variable-frequency drive.
Selection Procedure The chiller capacity tables cover the most frequently encountered leavingliquid temperatures. The tables reflect a 6°C [10.8°F] temperature drop through the evaporator. For other temperature drops, apply the appropriate performance data adjustment factors. For chilled brine selections, refer to Figures F-3 and F-4 for ethylene and propylene glycol adjustment factors.

Generic Building Automation System Controls Simple Interface with Other Control Systems Microcomputer controls afford a simple interface with other control systems, such as time clocks, building automation systems, and ice storage systems. This means you can have the flexibility to meet job requirements while not having to learn a complicated control system. This setup has the same standard features as a stand-alone water chiller, with the possibility of having the following optional features.
Generic Building Automation System Controls Tracer Summit™ Controls — Interface with theTrane Integrated Comfort System (ICS) Trane Chiller Plant Manager with ICS The Tracer Chiller Plant Manager building management system provides building automation and energy management functions through standalone control. The Chiller Plant Manager is capable of monitoring and controlling your entire chiller plant system.
