OASE Oasis IceFree Thermo 330

The optimized  ice free holder Oase IceFree Thermo 330 with frost monitor function reliably prevents the complete freezing of your pond at temperatures down to -20°C. Around the float, it provides an ice-free surface through which the oxygen supply is permanently guaranteed and through which harmful putrefactive gases can escape. This allows your pond inhabitants and pond plants a safe wintering.
The integrated frost monitor function activates this ice free holder only when necessary, depending on the temperature (when there is a danger of frost). On warmer days, this ice free holder is not activated and therefore does not consume unnecessary electricity.
Due to its active heating element, the Oase Icefree Thermo 330 is suitable for both permanently cold frost periods and shallow ponds. Warmer temperature zones at the bottom are maintained.
