Description
The device reduces the quantity of Legionella bacteria that exit the device. Major components may include a disinfecting chemical inlet, mixing chamber, thermal element, housing, filtration media, and ultraviolet (UV) light source. The performance requirements in this standard are for full systems and are not intended to apply to components (i.e., filters).
Size Range - Plumbed Devices
Include inlet sizes from NPS ¼ inch (DN 8) through NPS 1-½ inch (DN 40).
Flow Range
Device(s) may provide flow rates up to 100 GPM (378.5 L/min).
Temperature Range
Inlet and outlet water temperature ranges from 33.0 °F (0.56 °C) up to 180 °F (82.2 °C).
Pressure Range
A maximum design pressure of 125.0 psi (827.4 kPa).
