Whitmore Hyperion® zinc-free hydraulic oil is the direct answer to how zinc-free hydraulic oil prevents valve deposits — and this episode breaks down exactly why ashless additive chemistry outperforms conventional zinc-dithiophosphate packages in high-pressure hydraulic systems, turbines, and flooded-screw compressors.

Zinc-based antiwear additives degrade under heat, leaving metallic ash deposits that coat spool valve lands and cause spool valve stickiness, sluggish response, and unplanned downtime. Whitmore Hyperion eliminates that failure mode entirely. Its ashless, zinc-free additive system is engineered for severely hydroprocessed paraffinic base oils, keeping control valves deposit-free and fully responsive. The payoff: the conventional Hyperion line extends oil change intervals by up to 50% over standard mineral oi ...
