MultiTherm FF-1 Flushing Fluid

MultiTherm FF-1 ® Flushing Fluid is for use in start-up or general maintenance of heat transfer fluid systems. During new equipment start-up, it is an economical way to remove loose material such as weld splatter, fine particulate matter, etc. left in lines and equipment, along with oil and some preservative coatings. It is useful for general maintenance purposes for removing used heat transfer fluid from a system prior to recharge or changeover to another fluid.

MultiTherm FF-1 ® Flushing Fluid is formulated to be compatible with MultiTherm and most other heat transfer fluids so that small residual amounts left in the equipment will not be a problem.
