Mevas recently supplied the entire power and automation control of a new vacuum system, for an important paper mill of northern Italy.
System allows to manage paper mill flat table working parameters.
A 315 kW pump is driven by an inverter in order to control main line vacuum value.
In addition, each dewatering box is managed by a control valve driven by a 4-20mA loop, to guarantee vacuum level required for desired production.
An HMI allows to manage main settings of the system, and notify operators in case of faults or particular alarms.
As Mevas automation standard, HMI graphics are in accordance with real layout of the plant in order to obtain a user-frendly interface for operators and maintenance managers that are allowed to monitor constantly each parameter of the system.
As usual, thanks to its integration between process and automation know-how, Mevas have been able to successiful start-up all the system.
