The AFE-Story begins
Frank Fröhlich, a pioneer in the area of heat recuperation, starts developing Heat Exchangers in the late 50’s. He founds an individual company.
Frank Fröhlich registers a patent for his Glass Plate Heat Exchanger.
1972 & 74
Frank Fröhlich founds Air Fröhlich AG for energy recuperation. Only two years later, the company is sold to the Arbonia-Forster group and relocated to Arbon (TG).
Another two years later, the first aluminium plate Heat Exchangers are produced.
The Seventies are the decade of new developments at AFE: the company invents Heat Exchangers with glass tubes, flue gas and, in 1979, the ANOX air heater.
The first Heat Exchanger with PTFE tubes is installed in a waste incineration plant.
40 yours after the foundation of Frank Fröhlich’s individual company, the unique COAX-System is applied for the first time in a Smoke Gas/Water Heat Exchanger. Two years later, the company is certified by the SQS (Swiss Association for Quality and Management Systems) according to ISO 9001.
