@refrigerationmentor: Can dry ice really form in a CO₂ system during service work? Comment your thoughts below. Dry ice is possible in CO₂ refrigeration, but it is extremely rare during normal operation. The biggest risk shows up during charging or when pressures fall below the triple point and liquid CO₂ is introduced too quickly. • Dry ice forms below 61 psi or 4.2 bar • Charging liquid CO₂ below the triple point creates risk • Most cases occur in gauges or service hoses • Operating systems remain above the triple point • No dry ice risk once the system is running normally • Pump down procedures are critical during service • Liquid line filter changes require controlled pressure Knowing this helps technicians work safer and avoid unnecessary risks when servicing CO₂ systems. 👉 Follow us and explore the Refrigeration Mentor community through the link in our bio to learn alongside technical specialists supporting the industry. #RefrigerationMentor #refrigeration #co2 #gonatrefs #hvacr #commercialrefrigeration #supermarketrefrigeration
