Find the product that best suits your needs and your application among the different ranges and qualities that we present to you.
Our alternative to harmful chlorofluorocarbon gases (CFCs) as Repsol's High-Purity Liquefied Gases (HPLGs) are not harmful to the stratospheric ozone layer, with zero destruction potential for that layer (ODP=0). They also do not contaminate the environment as they have a practically non-existent potential for global warming compared to CO2 (GWP<5) and a life span of around a few weeks or months.
