About Autocascade Cryogenics

The ISA Autocascade cryogas is the newest & best among the cryogas solutions available world wide.

This unique gas mixture, developed from a deep understanding of autocascade operations, is one that works as a drop-in replacement for other refrigerants for cryo temperatures: works better, faster, cooler and easier.
