CO₂: environmentally friendly cooling
Cooling is an invisible but essential technology: it safeguards food products, preserves medication, allows for industrial production in sectors where temperature control is paramount.Now, however, the choice of cooling fluid has become not only a technical but also an environmental issue.
After years of using synthetic coolants, often with serious effects on the climate, the market is moving towards natural solutions.One of the most interesting is CO₂ (carbon dioxide), already widely adopted in the commercial field and increasingly widespread in industry.

Why CO₂?
CO₂ is a natural, widely available cooling gas, and with a GWP (global Warming Potentia) of just 1, virtually zero compared to fluorinated gases.
The ODP (Ozone Depletion Potential) is 0, thus has no impact on the depletion of the ozone layer.
In terms of plant engineering, CO₂ operates in transcritical mode, i.e. at very high operating pressures of up to 90 bar and above.This calls for specific components, designed to withstand these conditions, but it also allows for excellent performance, especially in cold or moderate climates.
The benefits of CO₂ plants
L’anidride carbonica ha un ottimo scambio termico e un’elevata densità, che permettono di progettare impianti compatti, efficienti e performanti. È il gas refrigerante ideale per applicazioni che richiedono temperature basse e stabili, come celle di conservazione, tunnel di abbattimento e magazzini refrigerati.
Cardon dioxide has an excellent heat exchange and high density which allow for the design of compact, efficient and high-performance systems.It is ideal for applications that require low, stable temperatures, such as cold storage rooms, blast chiller tunnels and refrigerated warehouses.
Stefani Gas Coolers
Stefani proposes a range of gas coolers designed for use in supercritical and subcritical systems.The machines are manufactured with a circuit capable of handling pressures up to 130 bar.
The modular, customisable structure of Stefani gas coolers makes them suitable for custom designs, especially in the industrial field.They are the result of a consolidated experience in heat exchange, applied to the requirements of new, natural coolants.
Sustainable technology, ready for the future
Adopting Co₂ means reducing the environmental impact without sacrificing cooling power.It is a both a technical and strategic choice: it allows companies to evolve and embrace a cleaner, more responsible cooling system.
With its gas coolers, Stefani provides access to technology that is ready to tackle the challenge of ecological transition.
