Electric immersion heaters are available as an option and are located in the basin of the tower. They are sized to maintain a +40°
F (4,4º C) pan water temperature at 0°F (-18º C) ambient with the fans off *. They are furnished with a combination
thermostat/low water protection device to cycle the heater on when required and to prevent the heater elements from energizing unless
they are completely submerged. All components are enclosed in rugged, weather proof enclosures for outdoor use. Heater control packages
that include contactor, transformer or disconnects are available.
(*) - Electric heater selection based on 0°F (-18º C) ambient temperature. For alternate low ambient heater selections
consult the factory.
