The heating rods HR are used for temperature control by biological acid reduction and by fermentation of special mediums that do not ferment easily.

The heating rods HR are available in two versions – HR 1.000 for insertion in the top vent of the tank or the barrel and HR 2.000 for insertion in the racking point through the flap-valve. Both models are regulated with a thermostat that reacts to the measured temperature of the fermenting medium.

The temperature can be accurately selected by turning the degrees button. When the set-temperature is reached, the heating rod switches itself off. When the temperature decreases, it will switch itself automatically back on. This prevents the wine from over-heating and the set temperature is kept stable, as required for example, by biological acid reduction.

The HR heating rods are a cost-effective and flexible solution for users requiring heating only occasionally for relatively small containers.
