Shrieve Products International
Refrigeration
Shrieve is a leading global supplier of alkylbenzene refrigeration oils. These oils are sold under the trade name ZEROL ™. Major approvals have been gained from OEMs including York, Tecumseh, Bristol, Scroll Technologies, ThermoKing, and Matsushita. Products are distributed through global partners to the OEM and aftermarkets. Progressively we have added ester, polyalkylene glycol and selected mineral oils to our range.
HCFC applications
ZEROL ™ alkylbenzene oils have several major advantages over mineral oils in applications with R22, including better low temperature miscibility, and superior thermal and oxidative stability. Quality is also more consistent because ZEROL ™ is a synthetic product.
ZEROL ™ alkylbenzene oils have broad industry approval including names such as Bock, Danfoss and Carrier.
ZEROL ™ oils have been the choice for many of the new service blends designed to replace R12 and R502. These blends include MP39, HP80, and HP81.
Ammonia applications
With current growth in Ammonia refrigeration applications, ZEROL™ alkylbenzene oils have seen renewed interest and growth. The good low temperature performance and excellent thermal and oxidative stability offers major advantages over traditional mineral oils for ammonia applications, while providing more attractive cost performance than other synthetics. The excellent chemical stability of these oils results in varnish and coke free operation thereby extending maintenance intervals and improving efficiency of the refrigeration system.
HFC applications
Recent studies have shown that oils derived from ZEROL™ alkylbenzenes can be used with HFC refrigerants such as R134a, R407C, and R410A in specific applications. These applications include household refrigerators, window air conditioning units, and small split systems. Major advantages of using ZEROL™ alkylbenzene oil instead of polyolester oil in these HFC systems include significant cost saving in both oil and in handling procedures, and also superior lubrication in certain systems.
For systems that require polyolester oils, Shrieve also offers ZEROL™ ESTER polyolester oils. These oils come in a variety of viscosities, and have years of proven reliability.
New developments
• To complement our product range, more recently Shrieve have introduced specific high quality mineral oils for use in ammonia and hydrocarbon applications.
• We are currently also working to introduce PAG based oils for application in CO2 systems.
• At this time, we are also in the process of commercialising a brand new lubricant enhancer family, known as our "ICE" technology. These products are to be branded for stationary refrigeration as ZEROL ICE™ range and will be launched in Europe during 2005. ZEROL ICE™ is an innovative oil enhancer that when added to existing lubricants at additive levels, can provide major improvements in lubricity and wear performance. This can lead to major benefits in terms of:
•INCREASED SYSTEM EFFICIENCY/REDUCED POWER CONSUMPTION
•EXTENDS SYSTEM LIFE BY REDUCING WEAR AND SYSTEM LOADING
•ENHANCED COOLING PERFORMANCE AND NOISE REDUCTION
