Flushing fluid is intended for use during startup and general maintenance of heat transfer fluid systems. The FF-1 from MultiTherm Corp., Malvern, Pa., can be used in heat transfer fluid applications to remove loose material (weld splatter, fines, particulate matter, etc.) left in lines and equipment along with oil and some preservative coatings. Rated HT1 for incidental contact in food applications by NSF, the flushing fluid is now food certified in Canada.

Flushing fluid also is useful for general maintenance for removing particulate matter and used heat transfer fluid from a system prior to recharge or changeover from one fluid to another. FF-1 is compatible with all of the company’s heat transfer fluids and as well as most other manufacturers’ fluids.
