Qwik System Flush® is used to flush contaminants such as residual oil, acid, or moisture from refrigeration line sets. If you can't replace refrigeration line sets after a burnout or R-22 to R-410a change out then you should use Qwik System Flush to remove residual contamination. Qwik System Flush®, a patented formulation, is 5-10 times more effective in acid removal, moisture & oil absorption than competitive products.
