  • Based on TYFOXIT®, enhanced TYFOXIT® F refrigerants offer even better viscosity characteristics. As a result, they provide high refrigeration performance and lower energy costs for existing systems as well as the ability to dimension smaller components when planning new systems.
  • The long-life corrosion protection provided by TYFOXIT® F refrigerants includes all the materials typically used in chiller construction including steel, stainless steel, iron, brass, copper, red brass, bronze, and aluminum.
