Sustainable refrigeration and air-conditioning technology – for the good of your company and nature.

The fact that we manufacture eChiller in-hoouse makes us the perfect contact for all of your questions regarding the installation and maintenance of eChiller, your sustainable refrigeration and air-conditioning solution. The good news up front: Since it uses only 60 liters of pure water in a vacuum, eChiller is very low on maintenance. Inspections and maintenance required by the F-Gas Directive are not relevant and maintenance does not require a trained and certified refrigeration specialist. That is really quite unique in the world of refrigeration and air-conditioning technology.

To give you a quick and uncomplicated overview of our refrigeration and air-conditioning technology, we have answered a number of questions you may have.
