MAK FRHF B
These are water in oil emulsions . in these fluids , water is suspended in petroleum oil which, at 60% by vol./mass, makes up to the bulk of the product .They offer much greater lubrication and corrosions resistance than HF-A fluid and in some offer performance approaching that of minerals oil. The water provides fire extinguisher mechanism.
Performance Level:
IS 10532 (Part 2): 1983 [Reaffirmed 1998]
Application:
This fluids are suitable for use in steel mills and coal mines , also suitable for use in hydraulic systems, Where the equipment is designed to operate with HF-B fluids They are also used in plastics and die casting industries in injection moulding machines.
