Description
Zinc-free hydraulic fluids have recently played an increasingly important role in industry.
In many cases, the use of zinc-free hydraulic fluids is a necessity, for example in the hydraulic systems of processing machines, where the entry of hydraulic fluid into the coolant cannot be completely avoided.
The RENOLIN ZAF D series of mineral oils are ash-free products prepared using zinc-free technology, which additionally have good anti-corrosion properties, for use in heavy-duty industrial systems requiring a working fluid of the HLPD level according to DIN 51 524. The special additives introduced into the products of this series significantly reduce the formation of sediments and aging products.
