Up to 4 CCS units can be permanently attached to one mixing head using a Colour Switching Manifold, containing one or more flip-flop switching valves, mounted on the mixing head.
This reliable and economic solution, allows for the on-the-fly change of colour: the operator simply switches off one unit and starts the other one, and the pressurized flow of the new colour operates the flip-flop valve allowing the new stream of colour paste to reach the mixing chamber.
A small flushing cycle is required to clean the tiny conduit carrying the colour into the mixing chamber, with a waste of less than few grams of chemicals.
