Sinking Tank De-Icer

This Sinking De-icer (#10N & #15N) will sink to the bottom of the tank, and is thermostatically controlled with an automatic shut-off. Since it operates at the bottom of the tank, it is less likely to be disturbed by livestock. Each unit comes with a galvanized wire Guard/Stand (#88R). With the guard in place, the Sinking De-icer may be used in plastic tanks. Patented.
