Pallas (Sita) UV 460 AL2 Ultra Violet System 80w 85 l/min 1in Male Connection

Sita 460 AL2: 80W UV Disinfection System with Lamp Countdown (85 l/min)

The Sita 460 AL2 is part of SITA's AL domestic UV range, manufactured in Italy to ISO 9001 quality standards and WRAS approved. Like every Sita AL system, it uses a 304 stainless steel treatment chamber and disinfects water by exposing it to UV-C light as it passes through, inactivating bacteria and viruses without any chemicals or additives.

The AL2 control adds a digital day-countdown display and an audible alarm when the lamp reaches end of life, so replacement timing is never a guess — an upgrade on the basic AL version's simple green/red LED indicator.

Specifications

Who it's for

• Larger properties and small commercial premises needing high flow capacity on a 1in connection
• Private water supplies, boreholes and wells with higher demand
• Anyone who'd rather not rely on remembering an annual lamp-change date

Why it matters

UV systems should be sized generously against your actual site flow rate — as a rule of thumb, the UV's rated flow should be at least 4 times your required or achievable flow, or you should restrict flow to no more than 38% of the system's maximum rating. We'd also recommend physical pre-filtration ahead of the UV rather than relying on the UV alone: a triple-filter setup (5 micron string wound, 1 micron polyspun, then a 0.45 micron absolute filter) is a common specification, with two absolute filters in parallel where higher flow is needed.
