1-1 Introduction

Sterling SCW Series central water chilling stations are available in water-cooled and remote air-cooled designs. They differ only in the condensing media used. The SCW Series units are configured with two independent circuits using multiple compressors for each circuit. This manual lists information for these units.

SCW Series chilling stations may be configured with stainless steel pump tanks for use as reservoirs for chilled water processes. These dual-well models hold hot and cold water before and after it is pumped through the chiller. Tanks have recirculation pump(s) to send return water to the chiller and process pump(s) to pump cooled water directly to process. Standby pumps may be utilized to distribute pump service or to allow uninterrupted chiller operation during pump maintenance.

Properly installed, operated, and maintained SCW Series chilling stations provide many years of reliable operation. To get the most satisfaction from your new chiller, read and follow the instructions in this manual.
