Introduction

Overview of Design

The Stealth™ air-cooled chiller was designed to meet the demanding requirements of today's

environment. The design transforms technology into performance on which you can depend.

Trane engineers brought innovation to every component in the next-generation Trane

Stealth

chiller. The result: the highest efficiency, improved system flexibility and performance, and the

lowest published sound levels—all while delivering improved reliability and lower maintenance

requirements.

At the core of the Stealth air-cooled chiller’s performance is AdaptiSpeed™ technology—the

integration of an all-new, direct-drive, specific-speed screw compressor; permanent magnet

motors and the Trane third-generation Adaptive Frequency™ drive, AFD3.

AdaptiSpeed Technology

AdaptiSpeed technology delivers unmatched efficiency with some of the lowest sound levels in the

industry.

• Trane third-generation Adaptive Frequency™ drive (AFD3) – The AFD3 offers a part-load

efficiency improvement of more than 40 percent when compared to constant-speed chiller

designs.

• Direct-drive, specific-speed screw compressor—Optimized for variable-speed operation, it

delivers peak efficiency under all operating conditions.

• Variable Speed, Permanent magnet motors—The compressor’s and condenser fans’

permanent magnet motor design is up to 4 percent more efficient than conventional induction

motors.
