SITA UV 405 System

This SITA UV system is often used to disinfect smaller drinking water streams. For example, galley water on board. This SITA UV 405 system is equipped with a high-quality 30-watt UV lamp, which achieves a dose of 300 J/m2 at a maximum of 20 liters/min (T=99, 1cm).

Available with LCD and LCD plus control module. The SITA UV systems are completely made of stainless steel and are characterized by a very high quality and long life.

This is the AL version. This consists of the lamp, reaction chamber, adapter and connections, and is therefore without control panel.

SITA UV LCD and LCD plus

These units come in AL, LCD or LCD plus versions. The standard LCD unit has a burning hour counter, an alarm LED and two alarm relays for switching a valve or external alarm display. The LCD plus unit also features a UV detector and a count down timer. 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 gets 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.
