Thanks to continuous synergetic work with its suppliers, Pastorfrigor is the first company in Italy inaugurating, in cooperation with ComoFrigor company and a Carrefour Associated, the first supermercato on 2000 sqm. with the new and ecological gas R454C, alternative to R744 (CO2) and intermediate gases (R448A and R449A).

The R454C refrigerant gas is a low GWP (146) a HFO refrigerant, the fourth generation of fluorine-based gases, compliant with the F-Gas and Ecodesign regulations. It is particularly suitable for low and medium temperature commercial and industrial refrigeration systems.

What are its benefits?

  • GWP

    Lower than 150

  • Low operating pressures

    Those we use to have with R404a for instance

  • Stability

    In extreme climatic conditions

  • Safety

    Low flammability and high gas loads allowed for a single circuit

  • Energy performance

    High especially in the hot months of the year

  • Cost of construction of the first system

    Similar to that with R404A/F gases

  • Easy maintenance

    Common components, known and simple procedures

R454C high capacity and efficiency

R454C refrigerant gas offers numerous energies saving benefits, furthermore, R454C is easily convertible from R404A design with few modifications.
This feature allows to upgrade existing systems without significant changes and building new ones at lower costs than solutions with CO2 refrigerant. Another advantage of R454C refrigerant gas is its improved efficiency. Compared to R404A refrigerant, R454C offers good thermodynamic properties. This means it can provide effective cooling performance with low power consumption.
It is important to underline that R454C refrigerant gas is non-toxic.

R454C for new systems and for renovations:

Ideal for new systems, it can be the basis for the renovation of your old systems.
Here some reasons to choose this ecological and efficient solution for new systems:

  • System Complexity

    Ease of installation; ease of maintenance with lower maintenance costs than a CO2 system.

  • Charge limit

    Per single circuit, up to 57 kg for R454C and 84 kg for R455A in commercial environments, without any limit in industrial applications with restricted or restricted access.

  • Costs

    Lower CapEx & OpEx, compared to gases that require a high technological level such as R744 (CO2) and Anhydrous Ammonia (NH3).

  • Energy efficiency

    Lower operating costs and lower overall CO2 emissions (very low TEWI over the life of the system, especially in the Mediterranean climate).

  • Environmental sustainability

    Compliant with F-Gas regulations for new plants, long-term sustainability.

  • Safety

    Low flammability, Operating pressures lower than R744 (CO2). It is widely proven that it is extremely difficult to create fire risk atmospheres with A2L gas (see Danfoss library for example). These gases are self-extinguishing and difficult to start a first flame.

In conclusion, the R454C refrigerant gas offers numerous advantages in terms of energy saving. Thanks to its thermodynamic properties, regulatory compatibility and improved efficiency, R454C can help reduce operating costs and promote energy savings.
