ABSTRACT:
The system includes a first module having a paint mixing and storage tank at a list location remote from any paint application point of use. The first module includes a remote pump for delivering paint at a first pressure from the tank to a local atmospheric pressure receptacle disposed at a second location in general proximity with paint application points of use. Excess paint delivered to the local receptacle is returned to the tank at the remote location. A secondary module includes a local pump to draw paint from the local receptacle for discharge into a main paint supply header at a third pressure. At least one separate and independent branch paint supply line is taken from the header for each spray booth, or groups of spray booths if located physically in close proximity to one another. Each of the branch lines is returned separately and independently through a back pressure control valve to the local atmospheric pressure receptacle. The first pressure is sufficient to supply paint to an atmospheric pressure storage receptacle disposed at the second location and is less than a second hypothetical pressure sufficient to supply paint to a furthermost desired point of paint application directly from the paint mixing and storage tank at the first location and at a predefined minimum paint application pressure. The third pressure is sufficient to supply paint to at least one desired point of paint application with the desired minimum paint application pressure and is less than the second hypothetical pressure.
