Schematic diagram: IceFree 20 – functional principle
176
IceFree
• To –20 °C an ice free area is generated around
the float body
• Ensures oxygen access to the water and allows
harmful fermentation gases to escape
• Extremely energy-efficient pump technology without
additional heating element for the IceFree 20
(requires a depth of at least 80 cm)
• Maintains the warm temperature zones on the floor,
particularly with the IceFree Thermo models
Ensure your pond is safe this winter
• The IceFree Thermo with an active heating element
is also suitable for shallower ponds, as well as for
continuing cold periods with freezing temperatures
• IceFree Thermo 330 contains an integrated frost
monitor function. It activates the device only when
there is danger of frost. This means energy is not
consumed on warmer days.
• Resistance heating technology for higher perfor-
mance in the freezing range, and protection against
temperature damage on air
Top 3 product characteristics
• To –20 °C an ice free area is generated
around the float body
• IceFree Thermo 330 with integrated
frost monitor
• Safe over wintering for flora and fauna
Recommendation
A minimum water depth of 80 cm is
recommended for reliable operation
of the IceFree 20.
