Why CO₂?

Carbon Dioxide (CO₂) was used as a refrigerant as early as the 1860’s, often found aboard oceangoing ships to preserve their catch; its use declined with the advent of synthetic refrigerants. Today, CO₂ re-emerges as a future-proof option for refrigeration. Regulations move the industry away from ozone-depleting and global-warming synthetic refrigerants to preserve our planet, meaning now is the right time to return to the beginning of refrigeration with Zero Zone Genesys™ CO₂ Systems.

CO₂ is an environmentally exceptional refrigerant with its ozone depletion potential (ODP) rating of 0 and a global warming potential (GWP) rating of 1. This makes CO₂ up to 4,000 times less impactful on global warming than HFC refrigerants. CO₂ is nonflammable and nontoxic, and it is a low-cost refrigerant. The recent advent of high-pressure, iron-impregnated copper has allowed the traditionally stainless-steel piping to transition to familiar brazed copper piping, further improving value and simplifying repairs. CO₂ is a smart choice environmentally and economically.

“I wanted the best product in here for the long run, not only economically but also environmentally. One leak in the old (HFC) system would cost you $10,000, $15,000, $20,000, where if there’s a leak in this, it’s very little. CO₂ seemed like a no-brainer.”

Right for Industrial

CO₂ is an effective refrigerant for industrial applications, either serving as the sole refrigerant in a CO₂ transcritical system or as a secondary refrigerant in a cascade system. Zero Zone has been successful serving customers with cold storage warehouses, food processing facilities, chiller applications (including ice arenas), and medical/pharmaceutical plants. CO₂ has a high cooling capacity, meaning smaller compressors and smaller line sizes, and it has a high density, leading to increased coil efficiency.
