About OASE Bitron C 72 W
The OASE Bitron C 72 W is a pond UVC pre-clarifier designed to reduce green water and assist filtration in larger garden ponds. The unit uses a total of 72 W UVC output delivered as two 36 W lamps (spare-part listing shows quantity two). The Bitron C is a flow-through UVC clarifier with a patented automatic cleaning rotor that continually cleans the quartz sleeve, helping maintain UVC effectiveness without frequent manual cleaning. It includes a visual inspection window and a safety switch that deactivates the lamp when the housing is opened. Manufacturer data list the electrical power consumption and total UVC power as 72 W, and a mains rating of 220–240 V (product text also references 230 V / 50 Hz). The unit comes with a 5.00 m power cable and universal stepped hose barb fittings to connect pipework from 3/4" up to 2". OASE states a manufacturer‑rated maximum operating pressure of 1 bar and provides physical dimensions (730 × 215 × 200 mm) and net weight (6.4 kg). OASE publish manufacturer pond-size guidance for this exact model: up to 75.0 m³ (75,000 litres) for general pond use, 37.5 m³ (37,500 litres) for ponds with fish, and 19.0 m³ (19,000 litres) for koi or heavily stocked ponds. The product page gives a listed flow range (manufacturer table) of Min. 12,000 l/h to Max. 40,000 l/h, and elsewhere on the same page a statement that the 72 W tube can handle 9,000 l/h without a bypass — see limitations for the conflict. The Bitron C is intended for inline installation and is shown as compatible with OASE BioTec, BioTec ScreenMatic² and ProfiClear filter families.
Best for
Inline UVC clarification in large garden ponds; integration with OASE BioTec/ProfiClear filtration systems; manufacturer-stated pond sizes up to 75,000 L (general), 37,500 L (fish), 19,000 L (koi).
Things to consider
The OASE product page contains inconsistent flow statements: the specification table lists a flow range of 12,000–40,000 l/h, while the descriptive text also states the 72 W tube can handle 9,000 l/h without a bypass. Both statements are presented by the manufacturer and are not reconciled here. OASE does not publish a maximum head (m), an IP/ingress protection rating, a flow vs. head curve, detailed installation depth limits, or specified maximum continuous running hours for this exact model on the product page.
Installation
Unit is designed for inline installation; comes complete with a universal stepped hose barb (¾"–2") for inlet connections. Rated for mains 220–240 V. Maximum operating pressure stated as 1 bar. Manual bypass/throttle handle is provided for flow adjustment. The manufacturer lists compatibility with BioTec / BioTec ScreenMatic² / ProfiClear filter families.
Maintenance
The quartz sleeve is continuously cleaned by a patented cleaning rotor (self‑cleaning). Replacement UVC lamps are listed as UVC 36 W (quantity two for this model). The product page indicates there is no UVC operating‑hours meter. Manufacturer warranty is listed as 2 years.
Safety
The unit has a quick‑release closure and a safety switch that deactivates the UVC lamp when opened; OASE states this provides protection against eye damage. Housing is described as impact‑resistant plastic. No IP rating or additional electrical safety details are published on the product page for this exact model.
