Introduction

YORK Millennium® Air Cooled Screw Liquid Chillers

28971AR

YORK Millennium Air Cooled Screw Compressor machines are the state-of-the-art in air-cooled chillers, providing chilled fluids for all air conditioning applications. Completely self-contained and designed for outdoor installation, these chillers employ new, low noise, energy efficient, serviceable, semi-hermetic screw compressors designed and manufactured specifically for this new product line. These compressors, with reliable twin-screw technology, are ideally matched to evaporators and condensers optimally configured for superior heat transfer and unit efficiency. Condenser coils are arranged to maximize airflow using full airfoil, high effi- ciency, low noise fans driven by low energy motors. The screw compressors, high efficiency evaporator, enhanced heat transfer condensers, and weather tight power and microprocessor control centers are mounted on a bolted, fully galvanized and powder painted, all steel base, for unsurpassed reliability and performance.
