The ice thickness controllers that check the working ice thickness of the cooling machine of a beer dispenser or other carbonic liquid, inside the controllers we have several models with different functions.

They can control in charge the compressor and the condenser fan. We have two inputs in the thermostat, or perform more functions through the ice thickness probe, through making a 12-V current through the water, which when the water freezes this current stops flowing which stops the voltage in the relay with the consequent stop of the compressor and condenser fan.
