CHAPTER 1 GENERAL INFORMATION
1.1 INTRODUCTION
AERCO’s DW-series heat exchangers provide potable hot water for commercial and institutional
applications. These heat exchangers are available in steam-to-water configurations and are equipped
with electronic controls. This manual addresses the steam-to-water double-wall heat exchanger with
electronic controls.
The three steam-to-water DW heat exchangers available from AERCO include the:
• DW-24 with 24 square feet of heating surface
• DW-45 with 45 square feet of heating surface
• DW-68 with 68 square feet of heating surface
Figure 1-1 illustrates a typical AERCO DW-series heat exchanger.
