Abstract
A method of fluidizing, conveying and/or atomizing powdery or liquid coating material in surface coating, particularly in electrostatic surface coating. An inert gas under high pressure is reduced to a lower, operating pressure, whereby it cools to a temperature below the ambient temperature, and is employed as compressed gas for fluidizing, conveying and/or atomizing coating material.
Claims6
A method of providing pressurized fluid to a coating system having a pressurized fluid supply line, said method comprising the following steps:
- providing a source of pure inert gas maintained at substantially ambient temperature, and at a pressure substantially higher than an operating pressure of said coating system;
- reducing the pressure of said inert gas approximately to said operating pressure, thereby causing the temperature of the inert gas to fall below ambient temperature;
- and
- supplying the reduced-pressure, cooled inert gas as a compressed gas in said pressurized fluid supply line for fluidizing, conveying, and/or atomizing a coating material.
