Teresstic AC 32


Teresstic™ AC 32 is a rust and oxidation inhibited ammonia compatible compressor and circulating oil. It is formulated primarily for equipment in ammonia production or service such as centrifugal compressors in chemical plants.

Teresstic AC 32 can be used in hydraulic systems where the pump manufacturer requires a mineral type oil that does not meet anti-wear additives such as those containing silver plated components. Nuto H oils are recommended where anti-wear properties are required by the hydraulic pump manufacturer.


Features and Benefits

Features Advantages and Potential Benefits
Oxidation Inhibited By employing highest quality solvent extracted paraffinic type oils, free from undesirable components and with high natural stability plus carefully selected inhibitors, oxidation resistance is provided to help prevent the formation of harmful sludges or acids
Foam ResistanceExcellent foam control helps to reduce the potential mechanical damage caused by air in oil
Rust ProtectionProtect metal surface from damage by inhibiting rust
Good DemulsibilityEntrained water separates readily



  • Systems with oil in ammonia contact
  • Circulating splash, bath and ring oiled systems supplying lubricant for bearings and gears on industrial machinery
  • Hydraulic systems that do not require an anti-wear additive

Health and Safety

Oils and greases in contact with skin can result in plugging of sweat glands and hair follicles or defatting of the skin. This may lead to skin irritation or dermatitis. Accordingly, good personal hygiene should always be practiced. Oil, greases, and other foreign materials should be removed from the skin promptly. TERESSTIC oils are readily removed from the skin by waterless hand cleaners, followed by washing with soap, warm water and a skin brush. Soiled clothing should not remain in contact with the skin. TERESSTIC can be removed from clothing by dry cleaning with solvents or by washing with a laundry detergent. If TERESSTIC comes in contact with the eyes, wash the eyes with fresh water until the irritation subsides.

WARNING: "Empty" containers retain residue (liquid and/or vapor) and can be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind or expose such containers to heat, flame, sparks, or other sources of ignition; they may explode and cause injury or death. Do not attempt to clean since residue is difficult to remove, and even a trace of remaining material constitutes an explosive hazard. "Empty" drums should be completely drained, properly bunged and promptly returned to a drum reconditioner. All containers should be disposed of in an environmentally safe manner and in accordance with governmental regulations.
