Transporting coating powder to coating unit involves correcting effective transport air rate by offset value dependent on transport air rate required to produce powder flow rate reference value
Transporting coating powder to coating unit involves correcting effective transport air rate by offset value dependent on transport air rate required to produce powder flow rate reference value
The method involves determining an effective transport air rate depending on a transport air rate required to produce a defined rate of powder flow, determining a transport air offset value associated with the powder coating unit dependent on a transport air rate required at a defined time to produce a powder flow rate reference value and correcting the effective transport air rate with the offset value. Independent claims are also included for the following: an arrangement for transporting coating powder to coating unit and an electrostatic powder coating device.
