CO₂ – an environmental refrigerant

• CO₂ installations provide improved energy efficiency by about 10% in average in mild to cold climate conditions and no global warming impact due to refrigerant leak compared to a conventional HFC direct expansion refrigeration system.
• CO₂ is an environmentally friendly refrigerant also used as an additive in beverages (carbonated drinks & soda water), available worldwide and affordable.
• Carrier has the right refrigerant solution for every application, but not every application will use the same refrigerant.

CO₂OLtec^TM – Key features & Benefits

• State-of-the-art CO₂ refrigeration system with low temperature and medium temperature refrigeration solutions for all food retail store formats, delivered as a turnkey solution
• Proprietary passive oil management system for the refrigeration racks to ensure higher reliability
• In the shop area and cold rooms the working pressure is reduced to 35-40 bar compared to max. 120 bar necessary in a transcritical CO₂ refrigeration circuit.
• Increased system efficiency by an average of 10% versus a traditional HFC or CO₂ cascade system through the booster design coupled with the advantages of not requiring oil separators and associated components
• Elimination of direct emissions due to climate neutral CO₂ refrigerant and reduction of indirect emissions through increased energy efficiency
• Broad remote service product portfolio, known as e*Service, ensure reliability and performance.
