Heissner UV lamp against algae up to 12 m3, 11 W WWF411 - 00

HEISSNER UV lamps irradiate flowing water with high-performance UV light. As a result of the radiation, the pathogens are decimated, the tiny floating algae clump together and, thanks to this, are captured in the pond filtration. UV lamp HEISSNER WWF411 - 00 Lamp with a power of 11 W, serves to sterilize and reduce the occurrence of algae in a pond up to a volume of 12 m³. It is equipped with a window for verifying the functionality of the UV lamp. Easy disassembly for changing the UV lamp and cleaning the UV silicon glass, including universal hose connections, practical holders for attaching to the filter or to the wall. Built-in safety circuit breaker. The fluorescent lamp in the UV lamp is recommended to be replaced after the season, although the fluorescent lamp lights up, it no longer has sufficient radiation power. At the same time, we recommend cleaning the silicon glass in the lamp during replacement. A suitable replacement UV lamp is HEISSNER ZF411 - 00. The following applies to the selection of a UV lamp: 1 W per 1000 l of pond water In the months from May to September, use the UV lamp for only a few hours: · with very cloudy water (opaque) 12 hours a day · with heavily cloudy water (only a few cm transparent) 8 hours a day · with slightly cloudy water (transparent to 50 cm) 4 hours a day · with clean water - no need to use a UV lamp In the months of October to April, the use of a UV lamp is usually not necessary. When using the UV lamp for the first time, turn it on for a maximum of 4 hours a day for the first week in order to prevent a rapid loss of oxygen caused by the death of algae. W x H 32 x 8 x 8 cm
