Rx11-flush™ cleaning solvent is an ozone-safe product formulated with a recently developed, patent-pending HFC solvent, says the company. It is engineered for flushing refrigeration and air conditioning systems due to contamination or burnout, or for component replacement. The solvent is designed to function like the old R-11 flushing process, but without any environmental concerns, the company says. The product is said to be strong enough to rinse away particulate, sludge, carbon residues, acids, and oils.
