Eco-friendly transport refrigeration
Transport of refrigerated and chilled products like food is on the rise worldwide. Whether goods are transported on the road, by train or ship, the cooling temperatures must be maintained exactly. Many transport refrigeration units contain fluorinated refrigerants acting as greenhouse gases in the atmosphere. These substances need to be replaced by refrigerants having less impact on the climate. read more

Climate friendly mobile air conditioning for buses
Buses are eco-friendly means of transport, nevertheless their climate performance can be increased still further. Today’s mobile air conditioning systems in buses still use the refrigerant tetrafluoroethane (R134a), a greenhouse gas with a 1,430 times higher impact to the climate than carbon dioxide. There is a climate friendly alternative: Some city buses already use CO2 air conditioning systems. read more

Mobile air conditioning with fluorinated refrigerants
An EU directive bans the use of fluorinated greenhouse gases with global warming potential exceeding 150 for mobile air conditioning systems in motor vehicles since January 2011. Thus the current refrigerant tetrafluoroethane (R134a) has to be replaced. Tests in laboratory and car showed that the new refrigerant 1234yf selected by car industry can lead to fires. read more

Mobile air conditioning in cars, buses and railway vehicles
An EU directive has banned the use of fluorinated refrigerants with a global warming potential of more than 150 in certain mobile air conditioning systems since Jan. 2011. It requires the previously used refrigerant tetrafluoroethane (R134a) to be replaced. Natural refrigerants are considered the best environmental alternative. Climate-friendly alternatives are also available for buses and trains. read more

Emissions and degradation products
Fluorinated greenhouse gases (F-gases, i.e. partially fluorinated hydrocarbons, fully fluorinated hydrocarbons, sulphur hexafluoride and nitrogen trifluoride) are used for purposes such as refrigerants, foam blowing agents in certain foam products, and insulating gas in switchgears. Some of these substances have an extremely high Global Warming Potential. read more
