CO2 Cascade Pays for Itself
An M&M CO2 Cascade Refrigeration System has many upsides, including:
- Lower energy bills
- Higher throughput (due to much lower operation temperatures)
- Reduced product liability insurance
- Potential for utility rebates
Another benefit: a typical M&M CO2 Cascade Refrigeration System will have a total ammonia charge that is far less than 10,000 lbs—resulting in dramatically reduced regulatory requirements. It’s common to have little-to-no premium charge when purchasing an M&M CO2 Cascade Refrigeration System versus purchasing a standard NH3 Refrigeration System.
The concept for M&M’s CO2 Cascade Refrigeration System is based on a cascade system that combines the advantages of CO2 on the low-temperature side with ammonia on the high-temperature side. Ammonia is limited to the engine room—only CO2 is present in working, processing and storage areas.
A CO2 Cascade Refrigeration System operating in a typical cold storage building when compared with a typical two-stage ammonia refrigeration system uses significantly less power and is therefore significantly more efficient. The CO2 Cascade System provides cooling and freezing storage at temperatures between -10°F and +35°F and blast freezing at -45°F to -48°F air temperatures.
