CETUS® DE32, 68, 100, 150

PRODUCT DEscriptION

Cetus® DE oils are used for portable and stationary

rotary screw, rotary vane, and reciprocating

compressors.

CUSTOMER BENEFITS

Cetus DE oils deliver value through:

• Long life — Cetus DE oils have a low sludgeforming

tendency and a high solvency for deposits

that help to keep compressor parts clean. Their

ability to minimize oil consumption, carry over,

varnish, sludge, and deposits; as well as maximize

deposit-free valve life helps minimize compressor

maintenance and energy costs.

• Ignition safety — Cetus DE oils provide a greater

margin of safety than conventional petroleum

products because their flash points, fire points, and

auto ignition temperatures are much higher. They

are not, however, true fire resistant fluids.

FEATURES

Cetus DE oils are synthetic diester-based, oxidation

resistant, compressor oils.

APPLICATIONS

Cetus DE oils are used for portable and stationary

rotary screw, rotary vane, and reciprocating

compressors. While specific manufacturer

recommendations vary, the ISO 32 and ISO 68 grades

are most commonly used for rotary compressors, while

higher viscosity grades are preferred for reciprocating

units.

These oils can be used in compressors

with the following gases: process air,

benzene, butadiene, carbon dioxide

(dry), carbon monoxide, ethylene,

furnace (crack) gas, helium,

hydrocarbon gases, hydrogen, inert

gases, methane, natural gas, nitrogen, propane, sulfur

hexafluoride, and synthesis gas.

Cetus DE oils can be used in contact with the following

seals, paints, and plastics:

• Viton

• High nitrile Buna N

• Teflon

• Epoxy paint

• Oil-resistant alkyd

• Nylon

• Delrin

• Celcon

These oils should not be used with:

• Neoprene

• SBR rubber

• Low nitrile Buna N

• Acrylic paint

• Lacquer

• Polystyrene

• PVC

• ABS

Cetus DE 100 is approved by:

• Matsubara Iron Works Co. Ltd, for use as a

reciprocating air compressor lubricant.

• Tanabe Pneumatic Machinery Co. Ltd, for use in type

H series reciprocating compressors.

Cetus® DE oils are registered by NSF and are

acceptable as lubricants where there is no possibility of

food contact (H2) in and around food processing areas.

The NSF Nonfood Compounds Registration Program is a

continuation of the USDA product approval and listing

program, which is based on meeting regulatory

requirements of appropriate use, ingredient review and

labeling verification.

Do not use in high pressure systems in the vicinity of

flames, sparks and hot surfaces. Use only in well

ventilated areas. Keep container closed.

Do not use in breathing air apparatus or medical

equipment.
