Technical Data Sheet CASTROL ICEMATIC SW RANGE DESCRIPTION: The Castrol Icematic SW range of lubricants is based on synthetic pentaerythritol esters, formulated using a highly effective low treat ashless additive package. They are completely wax free and have very low pour points to prevent blockage and to ensure clean evaporator performance. In addition, the products impart excellent oxidative and thermal stability as well as low temperature characteristics ensuring application over a wide temperature range.

APPLICATION: • • • • • •

The Castrol Icematic SW range is formulated for use in refrigeration compressors using HFC type refrigerants. They represent a truly versatile range of lubricants, compatible with both large industrial systems and small domestic units. The polyester base stocks are new components, which have been specifically synthesized by Castrol for the purpose of compressor lubrication in conjunction with HFC refrigerants. Castrol Icematic SW has been tested with different refrigerants and found to be miscible with most CFC, HCFC and HFC type gases. The unique properties of Icematic SW have enabled Castrol to pioneer conversions of existing CFC and mineral oil equipment to R134a and Castrol Icematic SW. This is achieved at the minimum of expense and disruption through a process called Retrofill. As no expensive hardware changes are required, conversion of existing equipment using the “Castrol Retrofill Procedure” will lead to dramatic cost savings.
