Abstract:
A apparatus for cleaning fluid systems and fluid system components comprising:a system housing having first and second compartments, the first compartment including a fluid outlet assembly adapted for coupling to a fluid system and the second compartment including a fluid inlet assembly;a first cleaning assembly including a first cleaning tank disposed in the first compartment and cooperatively arranged to contact fluid systems and fluid system components with a water soluble pre-cleaning solution including water and a water soluble cleaning agent to remove contaminants form fluid systems and fluid system components, and including a first fluid driving unit having an inlet coupled to the first tank and an outlet coupled to the first tank and to the fluid outlet assembly of said first compartment to draw the water soluble pre cleaning solution from the first cleaning tank and to selectively drive the water soluble pre cleaning solution to one of the fluid outlet assembly and the first cleaning tank;a second cleaning assembly including a second cleaning tank disposed in the second compartment and cooperatively arranged to contact the fluid system and fluid system components with a water soluble final cleaning solution to remove contaminants from the fluid systems and fluid system components, and including a second fluid driving unit having an inlet coupled to the second tank and an outlet coupled to the second tank and to the fluid outlet assembly of said first compartment to draw the water soluble final cleaning solution from the second cleaning tank and to selectively drive the water soluble final cleaning solution to one of the fluid outlet assembly and the second cleaning tank; anda rinsing assembly including 1) a first rinsing tank disposed in the first compartment and adapted to receive purified water, 2) a fluid driving having an inlet coupled to the first rinsing tank and an outlet coupled to the first rinsing tank and to the fluid outlet to draw the purified water from the first rinsing tank and to selectively drive the purified water to one of the first rinsing tank and the fluid outlet assembly, 3) a final rinsing tank disposed in the second compartment and adapted to receive purified water, and 4) a pump coupled to the final rinse tank to drive the purified water from the final rinse tank to the fluid outlet assembly components with a rinsing solution including water to remove contaminants, the water soluble pre-cleaning solution, and the water soluble final cleaning solution from the fluid systems and fluid system components.
