- No freezing: the Pontec PondoPolar ice preventer is a float and is used against the complete freezing of ponds at temperatures up to -10 degrees Celsius.
- Important gas exchange: the frost protection aid consists of two polystyrene parts and has several ventilation slots through which the important gas exchange can be done in the otherwise frozen pond
- Fillable: the freezer protection can be easily weighted with sand and lowered on the pond using the integrated countersink chamber to optimally adapt to the conditions in the garden pond
- Fit in winter: the extremely energy-efficient pump technology runs without additional heating element (requires depth of at least 80 cm) and maintains the warm temperature zones on the floor
