About OASE Bitron Eco 180 W
The OASE Bitron Eco 180 W is a pond UVC clarifier intended for installation directly on or in the pond (IP68). The unit contains a total UVC lamp power of 180 W (OASE lists three 60 W replacement lamps as the spare parts for this model) and is rated to treat flows between 10,000 and 50,000 litres per hour. It is supplied with a 5.00 m mains cable and is designed to operate from 220–240 V at 50/60 Hz. OASE states a maximum permitted operating pressure of 1 bar for this unit. The Bitron Eco 180 W includes integrated features listed by the manufacturer: an automatic bypass regulation (bypass membrane), eco-control to regulate irradiation duration, a patented automatic cleaning rotor for the lamp/quartz sleeve assembly, LED function check, a digital temperature display, and a UVC operating hours meter (12,000 h). OASE provides spare parts including the replacement lamp (UVC Eco 60 W INT, SKU 57077) and a quartz glass sleeve (D89.8 × 618.8 with rim). Physical dimensions given by OASE are 725 × 227 × 248 mm (L × W × H) and net weight 8.25 kg. Inlet/outlet connections are specified as 38 / 50 mm (1½" and 2"). This description only reflects specifications and features reported by OASE on the official product and spare-parts pages. It does not add operational performance claims or extrapolate values that OASE does not provide (for example, the manufacturer does not publish a flow vs head curve or a maximum head in metres).

Things to consider
OASE does not publish a maximum head (metres) or a flow vs. head performance curve for this model on the product page; these fields are therefore not available. No additional hose or installation depth limits are specified on the product page beyond IP68 and the stated connection sizes.
