DRY R™ is a fast-acting product that eliminates 60 drops of water and does not use methanol or alcohol to mask moisture. Instead, DRY R™ chemically breaks down the H2O molecule to eradicate moisture, dissolve blockages, and free up metering devices. DRY R™ conditions and stabilizes oil by lowering overall moisture parts per million - no particulate, gels, or polymers will form. Ideal for reducing the harmful effects of moisture in all refrigerants and oils. It is essential for removing moisture in 410a systems. Hose included.
