Refrigeration Innovation!
A refrigerator is one of the most important pieces of equipment in the kitchen for keeping foods safe. These electric units are so commonplace today, we forget a refrigerator was once little more than a box with a block of ice used to supply a rather undependable source of cold air.
Derived from petroleum, the compressor lubricant in refrigeration has many important functions. Even though the refrigerant is the working fluid required for cooling, the lubricant or oil is needed for lubrication of the compressor’s moving mechanical parts and minimizes mechanical wear by reducing friction.
