Abstract
An electrostatic coating system for dispensing multi-component waterborne coating materials from a coating material supply container having an insulated outer portion and a coating material supply line coupled to a dispenser, a metal tube disposed in the container in contact with coating material therein, a first non-conductive fitting coupling a first end portion of the tube to a first opening of the container, a second non-conductive fitting coupling a second end portion of the tube to a second opening of the container, and a cooling fluid supply device coupled to the tube.
Claims15
An electrostatic coating system for dispensing multi-component waterborne coating materials, comprising:
- a high voltage electrostatic coating material dispenser;
- a coating material supply container having an insulated outer portion and a coating material supply line coupled to the dispenser, the container having first and second openings therein;
- a metal tube having first and second end portions, at least a portion of the tube disposed in a portion of the container where the tube is contactable with coating material disposed in the container;
- a first non-conductive fitting coupling the first end portion of the tube to the first opening of the container, and a second non-conductive fitting coupling the second end portion of the tube to the second opening of the container;
- a cooling fluid supply device coupled to one of the first and second end portions of the tube.
In an electrostatic coating system that dispenses multi-component liquid coating materials supplied at a high voltage from a container electrically isolated from ground, the improvement comprising:
- a cooling fluid tube disposed in a portion of the container where at least a portion of the tube contacts coating material disposed therein,
- the cooling fluid tube having a first end portion coupled to a first opening in the container,
- the cooling fluid tube having a second end portion coupled to a second opening in the container,
- the cooling fluid tube electrically insulated from an outer portion of the container.
