YORK YCWS Water-Cooled models provide chilled water for all air conditioning applications that
use central station air handling or terminal units. They are completely self-contained and are
designed for indoor (new or retrofit) installation. Each unit includes accessible semi-hermetic
screw compressors, a liquid cooler, water cooled condenser, and a user-friendly, diagnostic
Microcomputer Control Center all mounted on a rugged steel base. The units are produced at an
ISO 9001 registered facility. The YCWS chillers  have certified ratings  in accordance with ARI
Standard 550/590.
