Rheem-Ruud commercial storage tanks are vertical tanks designed for
applications that require large quantities of potable hot water in short periods
of time. When used in tandem with RHEEM-RUUD commercial water heating
equipment, these storage tanks provide the flexibility needed for many
commercial applications. Installed individually, or manifolded, these storage
tanks can provide 80% draw capability without an appreciable temperature
decrease in single temperature applications.
