ABSTRACT:
A grounded insulated electrostatic supply tank comprised of a conductive tank that has several liners to fully insulate a waterborn fluid in the tank from ground. The interior of the tank and a sealed lid are coated with an insulating liner. An intermediate lining is placed in the tank and third interior insulating inner liner is inserted in the tank and has a lip that wraps around the upper rim of the tank and is sealed between the lid and the tank. Electrostatic spray equipment is connected to the tank by a coaxial hose having an inner non-conductive hose and preferably, an outer hose that is conductive. Inner non-conductive hose extends through the lid into an insulating teflon pick-up tube that extends to near the bottom of the tank. Depleted waterborn fluid in the tank is grounded after use by a manual probe or by a piston operated automatic grounding system.
