Drydene Radias® S ISO 220

Part #D34115

DRYDENE RADIAS® S 220 is a rust and oxidation (R&O) inhibited hydraulic fluid designed for industrial circulating systems, hydraulic systems and lightly- loaded gear systems that do not operate under extreme pressure. The ashless additive system provides reliable protection against rust, corrosion, deposit formation and wear without the use of traditional heavy metals.

Features & Benefits

DRYDENE RADIAS® S 220 is formulated to deliver excellent thermal and oxidative stability which promotes the reduction of sludge and other harmful contaminants:

  • It provides exceptional protection to bearings and circulating systems against rust formation, air entrainment and foaming.
  • Carefully selected zinc-free additives and base oils ensure outstanding demusibility and allow the fluid to purge water rapidly which guard critical systems from corrosion-accelerated wear.
  • Radias S fluids provide long service life and are more easily reclaimed after use due its ashless additive system.
