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

Building air conditioning

A lot of room air conditioners hangig on the face of a building

It is only recently that air conditioning has become relatively common in German buildings. The high standard of living has ramped up expectations concerning comfort and convenience in the home and particularly at the workplace, and this in turn has increased energy demand. The refrigerants used in more than 95 percent of Germany’s air conditioners strongly affect the climate. read more

Heat pumps

Heat pumps are coming into increasing use for heating of buildings and hot water production, as well as for commercial applications. Heat pumps can provide a broad range of heat outputs. The use of fluorinated refrigerants in heat pumps can potentially cause leakage and have a climate impact, whereby natural refrigerants are a more environmentally friendly alternative. read more
