Across a variety of compressor applications, some things remain constant. Operators are seeking greater efficiency in the face of an increasingly volatile range of temperatures. Staying at the forefront of lubricant technology, Chevron Products Company, a Chevron U.S.A. Inc. division, maker of technologically advanced engine oils, lubricants, and coolants, has expanded its line of Cetus® -branded compressor oils. Cetus®  compressor oils are already well-known among compressor users seeking to extend life-cycles, increase operator safety, and minimize oil consumption, but two new lines under the Cetus® brand hope to take that sterling reputation even further.
Cetus®  PAO and the rebranded Cetus®  HiPerSYN®  (formerly HiPerSYN) have joined Cetus®  DE to create a family of premium compressor oils formulated for use in a wide range of applications, including portable and stationary rotary screw, rotary vane, and reciprocating compressors.
“We saw the need to create a family of premium compressor oils and evaluated our existing product portfolio to determine the proper path to take,” says Jeff Snyder, industrial brand specialist, Chevron Products Company. “We have developed our new Cetus PAO product and joined it with the rebranded Cetus HiPerSYN and our original Cetus oil, Cetus DE. This combination of products gives our customers a single family of premium compressor oils that meet their varied needs while helping to extend equipment life and improve operational efficiency.”
Cetus®  PAO oils are synthetic air compressor lubricants formulated with the highest quality polyalphaolefin (PAO) base fluids. They provide thermal and oxidation stability, high viscosity index, high flash point, low pour point, and hydrolytic stability while protecting against rust, oxidation, foaming.
Cetus®  PAO oils are designed to meet the requirements of modern higher output, more efficient compressors. These units are more compact and operate at higher speeds than older compressors, resulting in higher temperatures.
Cetus®  HiPerSYN®  oils are designed to meet the needs of most compressor applications, especially those with wide operating temperature ranges that may challenge non-synthetic oils. These higher viscosity grade products are especially effective in high temperature applications, such as industrial bearings and gears that require R&O-type synthetic gear oil and sootblowers.
Cetus®  HiPerSYN®  oils are formulated with premium base oil technology and enhanced by a unique additive system that provides thermal and oxidation stability, high viscosity index, high flash point, low pour point, anti-wear protection, and excellent hydrolytic stability. Cetus HiPerSYN Oils also protect against the formation of oxidation byproducts and acidic materials which can eventually cause deposits and varnish, rust, oxidation, and foaming.
The original Cetus®  oil is still relied upon by compressor users. Cetus®  DE oils are synthetic diester-based, oxidation resistant compressor oils for use in portable and stationary rotary screw, rotary vane, and reciprocating compressors. These oils excel in applications that cannot tolerate carbon build up, and perform extremely well in high temperatures.
Cetus®  DE oils have a low sludge-forming tendency and a high solvency for deposits that help keep compressor parts clean. 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. The Cetus®  DE line built its reputation on safety and efficiency for compressor users, a reputation that Chevron takes seriously. With the addition of the PAO and HiPerSYN® lines, the name Cetus should continue to grow. ■
