For Industrial and Commercial Refrigeration needs, Frogen® has developed industry-grade Frogen® R134a, Frogen® R404A and Frogen® R507. Frogen® R134a is used primarily in medium temperature (> 35 deg F) applications such as cooling cases, vending machines, or ice cream servers. For lower temperature applications, we recommend Frogen® R404A and Frogen® R507 for efficient cooling in applications such as freezers, display cases and ice machines. Frogen® R407C and Frogen® R404A are also suitable for industrial refrigeration applications.
