In 1869, our great-grandfather Adalbert Fritz founded his company in Thuringia. When his son Franz Fritz, our grandfather, entered the company, the company name changed to “Adalbert Fritz & Sohn”. Affriso became a globally brand for temperature and pressure measurement. For 50 years, the company focussed on glass thermometers, medical glass instruments and laboratory equipment.
A small, thin-walled, circular and concentrically shaped metal sheet completely changed the Afriso world in the 1920s. Two diaphragm half shells form a capsule element which expands or contracts depending on the pressure. Precision pressure gauges, blood pressure measurement instruments and temperature controllers became the most important products for the time up to 1945 and the new beginning after that.
After World War II, Franz Fritz and his son Georg, our father, rebuilt the company in Kleingartach and in Güglingen/Württemberg. Pneumatic level measurement devices were developed on the basis of pressure measurement instruments, primarily for fuel oil storage tanks. Other innovations included overfill alarms and leak monitoring systems for the safe storage of mineral oil products. Technology for environmental protection became the main focus of the product range. The company secured the market leadership in this sector.
The early 1960s marked the beginning of the internationalisation of Afriso: sales and production companies were founded in almost all Western European countries. Afriso was renamed Afriso-Euro-Index. After the oil crisis in 1973/1974, the company developed a comprehensive range of products for the efficient and environmentally friendly operation of heating systems. After the political change in Eastern Europe, subsidiaries were founded in Hungary, Romania, the Czech Republic, Poland, the Ukraine, Russia and China.
