Drydene Radias® TC ISO 68

Part #D34212

DRYDENE RADIAS® TC 68 is a premium grade, rust and oxidation inhibited oil designed to provide superior lubrication of precision turbines, compressors and industrial circulating systems. It is built from severely hydroprocessed based oils and ashless additive chemistry to protect against rust, oxidation and foaming/ air entrainment.

330 Gal Tote, 5 Gal Pail, 55 Gal Drum

Product Applications

DRYDENE RADIAS TC oils are well suited for a variety of turbines, compressors and bearing systems where consistent oxidation stability, fast water separation and foam inhibition are essential:

• Steam turbines
• Marine turbines
• Hydroelectric turbines
• Centrifugal air compressors
• Electric motor bearings
• Non-EP bearings (plain, rolling element)
• Pneumatic air tools

Features & Benefits

DRYDENE RADIAS TC 68 utilizes advanced ashless additive chemistry to protect critical systems from harmful rust, corrosion and deposits that can result in costly repairs, replacements and downtime.

It delivers exceptional resistance to oxidation and thermal degradation which help minimize the formation of sludge, varnish and viscosity loss.

Radias TC provides good film strength and wear reduction through quick water separation within critical gear and bearing components. It’s active foam inhibitors help expedite the rapid release of entrained air and prevent sump overload so that key surfaces remain lubricated against wear.
