5 Myths About CO₂ Refrigeration Equipment That Should Be Debunked
19.11.2025 Share
The shift to natural refrigerants is no longer a trend — it’s a global standard. CO₂ (R744) is actively replacing synthetic refrigerants in retail, logistics hubs, agri-industrial complexes, and food production facilities. Despite this, the business environment is still clouded by myths that distort the perception of this technology.
At RalcoTechnic, we implement CO₂ solutions in complex projects every day. That’s why we’ve gathered the five most common myths — and debunked them based on real experience and engineering practice.
Myth 1. CO₂ systems are more expensive and unprofitable for businesses
This is one of the main concerns for companies considering a transition to natural refrigerants.
The truth:
Investing in CO₂ pays off quickly thanks to energy efficiency and operational optimization technologies.
Advantages:
• Heat recovery for DHW or heating
• Stable operation under high load
For logistics centers, retail, and food processing, CO₂ is often more cost-effective than conventional freon-based systems.
Myth 2. CO₂ is a dangerous refrigerant
This myth implies that high pressure automatically means higher risk.
The truth:
Modern systems are designed in strict compliance with PED/CE regulations. CO₂ is non-toxic, non-flammable, and non-explosive.
At RalcoTechnic, each project includes:
• Multi-level protection systems
• Controllers with automatic diagnostics
• Rigorous testing of each unit
• Precise pressure and mode calculations
In reality, CO₂ has a higher safety profile than many freons and propane-based systems.
Myth 3. CO₂ performs poorly in warm climates
Historically, CO₂ had certain technical limitations. But that’s long outdated.
The truth:
Inverter compressors, parallel compressors, ejector technology, and next-generation heat exchangers ensure efficient operation even at +40°C.
RalcoTechnic has completed projects that operate reliably during hot summers and in high-humidity conditions.
Myth 4. CO₂ systems are hard to maintain
Another stereotype that often lacks technical justification.
The truth:
Once installed, CO₂ systems require no more attention than freon-based ones. Modern controllers allow for remote diagnostics, and CO₂ consumption is minimal.
For businesses, this means:
• Simplified refrigerant logistics
• Accessible servicing
• Reliable performance even under peak loads
At RalcoTechnic, our service engineers undergo specialized training to ensure support at every stage.
Myth 5. CO₂ is just a temporary trend
Some companies assume that CO₂ will soon be replaced by other technologies.
The truth:
CO₂ is the primary direction for global refrigeration for decades to come.
Why:
• Full compliance with environmental standards
• Consistent availability and low cost
• Global decarbonization and Kigali Agreement regulations
• Scalable from small stores to large industrial sites
CO₂ is no longer an alternative — it’s the new industrial standard.
Conclusion
CO₂ refrigeration systems are safe, durable, and energy-efficient solutions that meet modern European standards.
Myths prevent businesses from seeing the bigger picture: CO₂ offers stability, resource savings, and a technological edge.
RalcoTechnic implements CO₂ systems for logistics, food processing, agri-industrial, and retail sectors — delivering engineering solutions that perform.
