About OASE Bitron C 55 W
The OASE Bitron C 55 W is a plug‑in UVC clarifier intended to treat green water in garden ponds. It contains a 55 W UVC lamp and a self‑cleaning rotor to reduce maintenance. Manufacturer data for this exact model state a maximum throughput of 30,000 litres per hour and an electrical consumption / UVC lamp power of 55 W. The unit is supplied with a 5.00 m power cable and is rated for 220–240 V, 50–60 Hz mains. The Bitron C 55 W is a flow‑through clarifier: water is routed past the UVC tube where suspended algae can be irradiated. The product has a visual inspection window for a quick function check and a manual throttle/bypass handle for controlling the flow through the UVC chamber. Inlet and outlet connections are stepped hose barbs to match common hose sizes (inlet 19/25/32/38/50 mm; outlet 25/32/38 mm) and the housing supports one inlet and two outlets. OASE lists the unit’s maximum permitted operating pressure as 0.5 bar. Dimensions and net weight are provided by the manufacturer (600 × 180 × 198 mm; 4.03 kg). OASE provides manufacturer suitability guidance in cubic metres rather than litres: suitable for ponds up to 60.0 m³, ponds with fish up to 30.0 m³ and koi ponds up to 15.0 m³. Replacement lamps and spare parts (for example replacement UVC bulb SKU 56636 and cleaning impeller) are listed by OASE. The product includes a safety‑interlock quick‑release closure that switches the UVC lamp off when opened and is described as VDE‑certified for eye protection. Where OASE does not state a value (for example maximum head or IP rating), those details are not available from the manufacturer pages for this model.
Best for
Ponds up to 60 m³ (general), ponds with fish up to 30 m³, koi ponds up to 15 m³ (manufacturer guidance).
Things to consider
OASE lists two conflicting minimum‑flow statements on its product pages: a narrative line that 6,500 l/h can flow past the UVC tube without a bypass, and the specification table which lists a minimum flow of 8,000 l/h. Both are manufacturer statements and are reported here without reconciliation. OASE product pages do not specify a maximum head (m), IP/protection rating, or a flow vs head curve for this exact model; those values are therefore unknown from first‑party evidence.
Installation
Intended to be plumbed into pond recirculation using the stepped hose barb sizes noted; unit has one inlet and two outlets and a manual throttle/bypass for flow control. Observe the stated maximum permitted operating pressure of 0.5 bar. Use the 5.00 m power cable to reach a 220–240 V supply. The quick‑release closure includes a safety switch that disables the UVC lamp when opened.
Maintenance
The unit includes a self‑cleaning rotor to reduce fouling of the UVC sleeve; OASE lists spare parts including a replacement UVC bulb (SKU 56636) and a spare cleaning impeller. The inspection window supports visual checks. Follow manufacturer guidance for lamp replacement intervals (manufacturer documentation/spare parts listing provided on OASE pages).
Safety
Manufacturer states 100% VDE‑certified protection against eye damage and a safety interlock that deactivates the UVC lamp when the housing is opened. Comply with standard electrical safety for 220–240 V appliances and follow OASE installation and maintenance instructions.
