The tank temperature is controlled by the PLC via the temperature sensor and water solenoid valve. The user can enter a required setpoint on the HMI and when the fermentation temperature rises above this setpoint the control solenoid valve will be opened to allow cold water to start flow through the tank side mount jackets. Once the temperature falls below the setpoint the valve will close and fermentation temperature will rise again. This continues process allows the tank to stabilise at setpoint over time.
The wine can be circulated on interval times setable from the HMI. An interval time, on time and off time is available.
The scraper can be started from control buttons at the foot of the tank.
