Long Oil Charge Life

Extremely high chemical and thermal stability — TOST oxidation life of 2,800 hours maintains oil integrity over long service intervals in large circulation systems where oil changes require planned shutdown and are a significant maintenance cost.

Excellent Water Separation

Rapid and complete separation from water — ASTM D1401 emulsion time 30 minutes at 82°C — and high resistance to emulsification, critical for turbine oil systems where water ingress from seals and condensate is a continuous challenge in steam and hydro turbine applications.

Outstanding Rust & Corrosion Protection

Passes both ASTM D665 Procedure A and B — including salt water corrosion resistance. Protects turbine bearings, journals, gears and system components in coastal power generation facilities and marine turbine installations.

Good Anti-Wear Protection

Good anti-wear properties protect plain and roller bearings, parallel shaft gearing and hydraulic pump components — extending equipment life and reducing maintenance in the wide variety of industrial equipment where DTE Oil Heavy is used as a circulating lubricant.

Excellent Air Release & Foam Control

Excellent air release and foam resistance prevent pump cavitation, noisy and erratic operation — critical for the large circulating oil systems of steam and hydro turbines where entrained air reduces pump performance and causes bearing damage.

Highly Versatile — Multiple Applications

The same DTE Oil Heavy covers turbines, plain and rolling bearings, parallel shaft gearing, moderate-severity hydraulic pumps, compressors and vacuum pumps in a single product — rationalising lubricant inventory and reducing misapplication risk across complex industrial installations.

Steam & Hydro Turbine Sets

Land-based and marine steam turbines and hydro turbines — including geared turbines — with splash, bath, ring-oiling and forced circulation systems where ISO VG 100 viscosity is specified by the OEM.

Bearings & Parallel Shaft Gearing

Continuous service lubrication of plain and rolling bearings and parallel shaft gearing in industrial machinery — where long service life, water separation and corrosion protection at ISO VG 100 viscosity are required.

Compressors & Vacuum Pumps

Rotary air compressors, reciprocating natural gas compressors and vacuum pumps handling air, natural gas and inert gases with discharge temperatures not exceeding 150°C — where ISO VG 100 provides adequate film thickness.

Moderate Severity Hydraulic Pumps

Moderate severity hydraulic pump applications where a long-life, water-separating circulating oil is preferred over a conventional anti-wear hydraulic oil — industrial and marine hydraulic systems specifying ISO VG 100 turbine oil quality.

Marine Turbine Applications

Marine steam turbine circulation systems and marine ancillary equipment — where the salt water corrosion resistance, long oil life and excellent water separation of DTE Oil Heavy are essential for reliable operation in the marine environment.

General Industrial Circulating Systems

Pumps, fans, blowers and other industrial equipment with circulating oil systems requiring ISO VG 100 where the long service life, versatility and proven reputation of the DTE Oil Named Series are valued.
