Overview

AFRISO-EURO-INDEX GmbH, commonly known as AFRISO, is a German environmental technology company headquartered in Güglingen, Baden-Württemberg. It develops and manufactures measuring, control and monitoring devices for building services, industry and environmental protection. The company traces its origins to 1869, when Adelbert Fritz founded a business in Schmiedefeld am Rennsteig in present-day Thuringia. With the entry of his son Franz Fritz, the firm operated as Adelbert Fritz und Sohn, and the telegraph abbreviation and brand AFRISO came into use. In the early 20th century, precision pressure gauges, blood pressure monitors and temperature controllers were among its key products. After the Second World War, Franz Fritz and his son Georg rebuilt the company in Kleingartach and Güglingen. Instead of pressure gauges, they produced pneumatic level measuring devices, mainly for heating oil storage tanks, and developed overfill prevention and leak monitoring systems for the safe storage of mineral oil products. In the early 1960s, the company established its own sales and partly production companies in almost all Western European countries, and the name evolved from AFRISO to AFRISO-EURO-INDEX. After the 1973/74 oil crisis, a broad product range was developed for the economical and environmentally friendly operation of heating systems. Following the political changes in Europe, subsidiaries were founded in Hungary, Romania, the Czech Republic, Poland, Ukraine, Russia and China. Today the company is run by the fourth generation, Elmar and Jürgen Fritz. AFRISO serves three main areas: building services (Haustechnik), industrial technology (Industrietechnik) and smart home. Its building services portfolio covers safety around tanks and heating, including overfill prevention, leak monitoring, heating and storage tank equipment, radiator valves and hydraulic balancing, manifold systems for heating, cooling and geothermal energy, pressure gauges, pressure transmitters, thermometers, level measuring devices, display, evaluation and control devices, and flue gas analysis devices. In industrial technology, AFRISO provides measurement, control and monitoring solutions, including stationary gas analysis. Its smart home offering, AFRISOhome, provides wireless building automation for room climate, comfort and safety. AFRISO also produces complex plastic manifolds for internationally leading system providers of underfloor heating, heating and cooling systems and geothermal energy as OEM solutions. The company has a service network for gas analysis, with service points for BlueLine handheld instruments and CAPBs sensor modules across Germany. Recent product news includes the VA 100, a compact 82-gram vane anemometer, and permanent monitoring of oil and grease separators for applications in gastronomy, meat processing, automotive workshops and petrol stations.

History

AFRISO-EURO-INDEX GmbH was founded in 1869 in Schmiedefeld am Rennsteig, in present-day Thuringia, by Adelbert Fritz. With the entry of his son Franz Fritz, the company operated as Adelbert Fritz und Sohn. The telegraph abbreviation and brand AFRISO was used. In the early 20th century, precision pressure gauges, blood pressure monitors and temperature controllers were among its most important products. After the Second World War, Franz Fritz and his son Georg rebuilt the company in Kleingartach and Güglingen. Instead of pressure gauges, they manufactured pneumatic level measuring devices, mainly for heating oil storage tanks. For the safe storage of mineral oil products, overfill prevention devices and leak monitoring systems were developed. In the early 1960s, the company founded its own sales and partly production companies in almost all Western European countries. The name changed from AFRISO to AFRISO-EURO-INDEX. After the 1973/74 oil crisis, a broad product range was developed for the economical and environmentally friendly operation of heating systems. Following the political changes in Europe, subsidiaries were founded in Hungary, Romania, the Czech Republic, Poland, Ukraine, Russia and China. Today the company is run by the fourth generation, Elmar and Jürgen Fritz. Key milestones include: 1920, production of capsule springs for precision pressure gauges, blood pressure monitors and temperature controllers; 1955, introduction of level measuring devices for heating oil tanks, followed by overfill prevention and leak monitoring systems; 1958, electronic level products expanded the range, especially for industrial applications; 1972, presentation of the first portable electronic flue gas analysis device on the market; 1981, market launch of the first compact plastic manifold system for underfloor heating. AFRISO develops and manufactures products for both building services and process engineering. Its portfolio includes overfill prevention devices, leak monitoring devices, equipment for heating and storage tanks, fittings for radiators and hydraulic balancing, manifold systems for heating, cooling and geothermal energy, pressure gauges, pressure transmitters, thermometers, level measuring devices, display, evaluation and control devices, flue gas analysis devices, stationary gas analysis and smart home technology. The company also produces complex plastic manifolds for internationally leading system providers of underfloor heating, heating and cooling systems and geothermal energy as OEM solutions. Its smart home technology is marketed under AFRISOhome. AFRISO maintains a service network for gas analysis, with service points for BlueLine handheld instruments and CAPBs sensor modules across Germany.
