Oase Bitron C 72 Watt UVC

Oase Bitron C 72 Watt UVC

High Output Self Cleaning UV Clarifier for Large Pond Filtration Systems

The Oase Bitron C 72 Watt UVC is a high performance ultraviolet clarifier designed to eliminate green water and reduce harmful bacteria in ponds up to 75000 litres. It targets suspended algae directly and, as a result, restores clear and healthy pond water even in larger koi and ornamental systems.

Unlike standard UV units, the Bitron C 72W features a patented automatic cleaning rotor. As water flows through the housing, the rotor continuously moves around the quartz sleeve. Consequently, it prevents debris and limescale from settling, which maintains strong UV penetration and consistent irradiation performance.

The integrated bypass system combines high flow rates with optimal exposure time. Because of this intelligent design, up to 9000 litres per hour can pass the UVC tube without bypassing the radiation zone. In addition, you can regulate the flow precisely using the built in throttle handle, allowing accurate adjustment to suit your pump and filtration setup.

A clear inspection window allows you to check bulb operation instantly. Furthermore, the intelligent UVC function monitor provides a visual indicator for lamp status and bulb replacement. Integrated magnets reduce limescale build up, which protects the quartz sleeve and supports long term efficiency.

Maintenance is simple. The quick release closure allows easy access to the bulb housing, while a built in safety switch automatically deactivates the UV lamp when opened. Therefore, it prevents accidental exposure and meets strict VDE safety standards.

The Bitron C 72 Watt is ideal for use with Oase ProfiClear, BioTec 30 and BioTec ScreenMatic 36 filtration systems. When paired with compatible Oase flow through filters such as BioSmart, BioTec and ProfiClear, it qualifies for the Oase Clear Water Guarantee.

Technical information

UV sizing and maintenance notes

Oase Bitron C 72 Watt UVC should be matched to the pond volume, flow rate and water clarity problem you are trying to solve. UV clarification works best when water passes the lamp at a suitable speed and the quartz sleeve is kept clean. If the flow is too fast, contact time can be reduced. If the lamp is old or the quartz sleeve is dirty, performance can drop even when the unit still appears to be switched on.

• Replace UV lamps as part of routine seasonal maintenance.
• Clean or inspect the quartz sleeve when water clarity starts to deteriorate.
• Match the UV to the pump and filter rather than installing it in isolation.
• Allow safe access for lamp changes and winter maintenance.

Good UV performance also depends on mechanical filtration. Removing fine debris before the UV helps the lamp work on green water algae more effectively.
