It uses medium-pressure lamp technology to achieve greater than 4 log in activation of Cryptosporidium and similar pathogens. It is compact, has a small footprint and can be easily retrofitted into existing treatment systems. It also features germicidal sensors, an automatic Quickwipe system and PLC-based operation and control.
