Hydrofluorocarbons (or HFCs) are the most widely used refrigerant gases for refrigeration systems, but they are partly responsible for global warming and the greenhouse effect. To prevent this, European regulations are becoming increasingly strict in order to limit their use. At the same time, researchers are trying to identify fluids with a lower GWP (Global Warming Potential) index.
Among these, CO2 is an increasingly interesting solution, as a natural gas with very limited polluting power (a GWP of 1, i.e. no impact on atmospheric ozone), and also widely available as a waste product derived from other processes.
For us at Friostar, environmental impact and safety have always been issues that are close to our hearts.
The use of CO2 for our refrigeration systems ensures a twofold benefit: it does not present dangers related to toxicity or flammability and has a much lower cost when compared to traditional fluids.
In addition, it does not even need to be recycled at the end of the system’s life.
In large applications, with distances of hundreds of meters between the products to be refrigerated and the refrigeration machines, a liquid CO2 forced circulation system offers important advantages such as:
– Lower flow rates required, and therefore smaller pipelines
– Lower energy consumption for pumping
– No temperature variation in evaporators
– No oil return problems
– Circulation of non-toxic fluid kept constantly in liquid phase
– High heat exchange efficiency
All systems are designed and manufactured to always guarantee:
- Compliance with established budgets
- Meticulous attention to detail
- High quality materials
- Long lasting durability
- Ease of use
- High energy efficiency
- Reduced operating costs
- Efficient, productive, and safe working conditions
