CO2 Cascade Support

M&M designed, built and installed the first CO2 Cascade Refrigeration System in the United States. Many competitors have followed in our footsteps, attempting to design and install their own interpretation of a CO2 Cascade Refrigeration System. Some of those systems have since failed to perform properly.

Have a question about your current system but you’re not an M&M customer? Doesn’t matter. We’ll answer your questions anyway. As a proponent of natural refrigerants, we recognize that we have a responsibility to assist all users of CO2 Cascade Refrigeration Systems—including systems not designed or installed by M&M Refrigeration.

You can monitor from one to 100 of your facilities—anywhere, anytime, including remotely from your laptop. In fact, M&M still supports the first control system we ever manufactured—dating back almost 25 years.
