Abstract
An electrostatic spraying installation for conductive liquid coating product comprises a circuit for distributing fluids including the conductive coating product. At least one coating product sprayer is fed by this circuit and is connected to a variable or interruptible high voltage supply. At least one insulated auxiliary coating product storage tank is adapted to be raised to the high voltage. The installation includes at least one rinsing product supply and at least one compressed air supply. The circuit comprises at least one mobile member isolator connected between two parts of the distribution circuit to isolate the upstream circuit part from the high voltage. The installation comprises an arrangement of valves on the upstream and downstream sides of the isolator connected to the rinsing product supply and to the compressed air supply for cleaning and purging the isolator before it is opened each time.
