The Trane Air-Cooled Chiller Model RTAC is the second generation of the air-cooled Series R chiller family. The RTAC offers high reliability, reduced sound levels, improved energy efficiency, and a smaller physical footprint, all due to its advanced design, low speed/directdrive compressor, and proven Series R chiller performance.
The Trane RTAC air-cooled chiller was designed to meet the demanding requirements of today's environment. The high-technology design transforms technology into the performance you can depend on. For example, its semihermetic, direct-drive compressor eliminates the need for a gearbox, a common component in many competitive chillers. This improves the unit's reliability, energy efficiency, and significantly aids in reducing unit sound levels and vibration.
Also, the Adaptive Control microprocessor aids in improving energy efficiency and provides more reliable operation by minimizing "chiller downtime". This is accomplished with the microprocessor control, which continuously monitors the operating conditions of the chiller and automatically initiates corrective action, especially during adverse conditions.
