SITA UV 412 System

This SITA UV 412 system is often used for the disinfection of drinking water, for example on board, or for legionella prevention. The UV system is equipped with a high-quality 40 watt UV lamp, which achieves a dose of 300 J/m2 at 45 liters/min (T=99, 1cm).

This system is available as a basic system, with LCD and with LCD plus control box. The SITA UV reactors are completely made of stainless steel and are characterized by high quality and long life.

Indicated price: SITA UV 412 AL (without control box, with adapter)

SITA UV AL, LCD and LCD Plus

These units are supplied in AL, LCD version or LCD plus version. The AL version consists of the lamp, reactor, adapter and connections, and is therefore without control box. The standard LCD unit has a burn hour counter, an alarm LED and two alarm relays for switching a valve or external alarm display. The LCD plus unit also has a UV detector and an optional 4-20mA contact. You will be notified if the lamp needs to be replaced. The UV detector measures the UV dose and can switch a solenoid valve if the dose becomes too low to keep your drinking water system clean. These solenoid valves are available separately from us.

What does the T-value mean?

This means the “Transmission Value” or clarity of the water. It is indicated in this case as 99% at 1 cm from the lamp. If the water is less clear, the UV dose will be lower.

For example, tap water is around 85-90%. Water from a water tank can be as low as 70%.

What can I do when I have a lower transmission value?

You could treat the water yourself with a carbon filter, for example. It is also possible to take a heavier UV system.

The lamp still works after 9000 hours. Should I change it?

Yes! The lamp will still emit blue light however, over time its frequency will become too low for proper disinfection.

Do I need to clean the quartz tube?

The quartz tube is the barrier between the water and the UV lamp. The cleaner it is, the better it allows the UV light to pass through.

We recommend cleaning this quartz tube when changing lamps. You can do this by soaking it in citric acid and then rubbing it with medicated alcohol.

Also inspect the condition of the O-ring and replace it if necessary.

How long does the quartz tube last?

Sita recommends replacing the quartz tube every 5 years for optimal disinfection.
