Rotary Cooker Fluid provides lubrication performance in continuous rotary cookers and sterilizers with minimal environmental impact to process cooling water. It starts with 99.9 percent pure base oils, free of impurities that both hinder lubricant performance and negatively impact the environment. These thermally stable fluids then are fortified with additives to provide protection against wear and corrosion. The fluid is NSF H2 registered and acceptable as a lubricant in and around food processing areas where there is no possibility of food contact.
