Oase Bitron Eco

Oase Bitron Eco UVC Clarifiers

Intelligent High Output UV Clarification for Large and Professional Pond Systems

The Oase Bitron Eco range represents the most advanced ultraviolet clarification technology within the Oase portfolio. Designed for large koi ponds, heavily stocked systems and commercial water features, these high performance UVC clarifiers combine maximum irradiation power with intelligent energy management.

Unlike conventional UV units, Bitron Eco models feature automatic bypass regulation and integrated eco control technology. As a result, they maintain optimal ultraviolet exposure even when flow rates fluctuate, while reducing energy consumption during periods of lower demand.

Eco Control and Flow Stability

Each Bitron Eco unit automatically adjusts irradiation intensity according to seasonal conditions. Therefore, output increases during peak algae pressure and reduces during cooler months. Consequently, energy usage can be lowered by up to 50% compared to traditional fixed output UV clarifiers.

A high volume irradiation chamber increases internal water retention time, ensuring suspended algae and harmful microorganisms receive longer exposure. In addition, the automatic bypass system adapts internal water distribution based on changing flow rates up to 50000 litres per hour. This guarantees consistent clarification across large scale systems.

Low Maintenance, High Reliability

The patented automatic cleaning rotor continuously prevents limescale and debris from settling on the quartz sleeves. As a result, UV penetration remains strong without manual cleaning.

The advanced UVC lamps offer up to 12000 hours of operating life, approximately 50% longer than standard bulbs. Furthermore, lamp replacement can be completed without dismantling the quartz glass, reducing servicing time significantly.

A digital display provides real time lamp status and water temperature monitoring, giving clear operational feedback at all times.

Oase Bitron Eco UVC – Frequently Asked Questions

What makes the Oase Bitron Eco different from a standard pond UV clarifier?

The Oase Bitron Eco range is far more advanced than a basic ultraviolet clarifier. Unlike traditional fixed output UV units, Bitron Eco models feature intelligent eco control technology and automatic bypass regulation.

This allows the unit to adjust irradiation intensity according to seasonal demand while adapting to changing flow rates up to 50000 litres per hour. As a result, it delivers more stable UV exposure, improved energy efficiency and superior performance in large koi pond systems.

How does the eco control system reduce energy consumption?

The integrated eco control system automatically adjusts UV output depending on algae pressure and seasonal conditions.

During summer, when algae growth is at its highest, the unit increases irradiation performance. However, during cooler months, it reduces output while still maintaining effective sterilisation. Consequently, electricity consumption can drop by up to 50% compared to conventional UV clarifiers that run at full power all year.

What pond size is the Bitron Eco suitable for?

The Bitron Eco range is designed for medium to very large koi ponds and commercial water features.

The correct model depends on pond volume, fish stocking levels and pump flow rate. The 120W model suits large private koi ponds, the 180W model is ideal for heavily stocked or high turnover systems, and the 240W model is designed for very large or commercial installations.

Correct sizing is critical. An undersized UV clarifier may struggle to maintain water clarity in heavily stocked ponds.

What flow rate can the Bitron Eco handle?

All Bitron Eco models are designed for high flow filtration systems and can manage flow rates up to 50000 litres per hour.

Thanks to automatic bypass regulation, the internal water distribution adjusts automatically to maintain optimal ultraviolet exposure, even if pump output fluctuates. This makes it particularly suitable for drum filter systems and variable speed pump installations.

How does the Bitron Eco control green water?

Green water is caused by free floating single celled algae. The Bitron Eco exposes pond water to UV-C radiation, which penetrates algae cells and disrupts their DNA. As a result, the algae can no longer reproduce and begin to clump together.

These clumped particles are then removed by your mechanical filtration system. It is important to understand that UV clarifiers neutralise algae rather than physically removing it.

Does the Bitron Eco harm beneficial bacteria?

No. Beneficial nitrifying bacteria live on surfaces inside your biological filter media. UV clarifiers only affect microorganisms that pass directly through the irradiation chamber in the water column.

Therefore, biological filtration remains unaffected while suspended algae and harmful bacteria are reduced.

How long do the Bitron Eco UV lamps last?

The Bitron Eco uses advanced UVC lamp technology developed in collaboration with Philips. These lamps have an operating lifespan of up to 12000 hours, which is approximately 50% longer than many standard UV bulbs.

However, even if the lamp still glows, UV output gradually reduces over time. For best results in koi ponds, annual lamp replacement is recommended.

What is the automatic cleaning rotor and why is it important?

The patented automatic cleaning rotor continuously moves around the quartz sleeves as water flows through the unit. This prevents limescale and debris from settling on the surface.

As a result, UV penetration remains strong and consistent without manual cleaning. This significantly reduces maintenance requirements compared to basic UV clarifiers.

Can the Bitron Eco be used on gravity fed and pump fed systems?

Yes. The Bitron Eco range is compatible with both gravity fed and pump fed pond systems.

It integrates seamlessly with Oase ProfiClear, BioTec 30 and BioTec ScreenMatic² filtration systems. It is particularly effective in high flow drum filter installations where consistent irradiation at varying flow rates is essential.

Where should the Bitron Eco be installed within a filtration system?

For optimal performance, the UV clarifier should be installed after mechanical filtration. This ensures suspended debris does not shield algae or microorganisms from ultraviolet exposure.

Thanks to its IP68 protection rating, the unit can be installed directly beside the pond or within a filtration chamber.

Does the Bitron Eco replace mechanical or biological filtration?

No. A UV clarifier is only one part of a complete pond filtration system.

Mechanical filters remove solids, biological filters convert ammonia and nitrite, and UV clarifiers neutralise suspended algae and harmful microorganisms. All three components work together to maintain stable and healthy water conditions.

Is the Bitron Eco suitable for commercial or estate installations?

Yes. The 180W and 240W models are particularly suited to commercial koi ponds, estate lakes, hotel water features and large ornamental systems.

Because of intelligent eco control and high flow capability, the Bitron Eco performs reliably in demanding and high turnover environments.

What maintenance is required?

Maintenance is minimal but important for optimal performance.

Annual UV lamp replacement is recommended. The quartz sleeves should be inspected periodically, although the automatic cleaning rotor significantly reduces limescale build up. Flow rate should also be checked to ensure correct irradiation exposure.

Why choose Bitron Eco instead of Bitron C?

The Bitron Eco range offers higher output models, intelligent eco control, automatic bypass regulation, longer lamp lifespan and digital monitoring.

Bitron C models are ideal for standard koi ponds. However, Bitron Eco units are designed for larger, high demand or professional installations where flow rate stability and energy efficiency are critical.
