R-454C

R-454C is a refrigerant gas blend of HFCs and HFO with an ultra-low GWP, below 150, meaning it is not restricted by the current F-Gas regulation (2024/573) and is exempt from the Spanish fluorinated greenhouse gas tax. It is an excellent solution for commercial refrigeration systems (preservation and freezing) and industrial refrigeration.
From the thermodynamic perspective, it is a refrigerant with similar capacity to R-404A and greater energy efficiency. In terms of safety, it is classified as an A2L refrigerant, requiring appropriate materials and charge levels for this type of safety classification.
