Pentair SLP/CLP UV System

That depends on the UV dose you need and your %UVT — the 18,925 LPM figure is the largest hydraulic capacity in the range, not a disinfection rating, so give us your dose and UVT and we will tell you the treatable flow.

Design flow, the target UV dose in mJ/cm² (which follows from the organism you are controlling) and your measured %UVT — without all three any flow figure is meaningless.

Both are low-pressure; amalgam lamps hold higher output over a wider water temperature range and suit larger duties, while LPHO is the efficient choice for steady conditions — we will recommend one with the sizing.

It handles corrosive saltwater without pitting, takes higher internal pressure than polypropylene or HDPE, and costs up to 50% less than a 316 stainless vessel.

Basic is included and covers standard operation; the optional PLC touchscreen package adds dose monitoring, logging and greater control, and it is the package that uses the 20210-UVS UV intensity sensor.

The LPHO lamps are rated for 12,000 hours of continuous operation and are still around 80% efficient at that point; amalgam lamp life is not published, so ask us for the figure on the model you are quoted.
