Complex automation Automatic control system of vacuum-condenser set (VCS)
The specific character of an automatic control system of VCS operation is using of several clappers of water feeding into the condenser which open/close depending on vacuum and also on temperatures of effluent gases and water that allows minimizing quantity of water consumption.
If the automatic control system of VCS is used simultaneously with automatic control system of sugar end division the water feeding is partly changed for preventive alignment of vacuum in collector at starting and stopping of a recurrent vacuum set.
