Our history
111 years of inventiveness, pioneering work and success
Albert Züllig was the inventor of devices that enabled fully automatic, level-dependent filling of reservoirs in water supplies for the first time in 1913. In his garage, as a freelance designer, he initially began to develop pump controls, as well as the necessary protective shut-offs and remote water level indicators. He brought these models to production maturity and attracted worldwide attention.
The Züllig company developed from a workshop into a company after cantonal fire insurance companies made their subsidy payments dependent on additional control technology. Albert Züllig developed battery-powered remote opening systems and, in keeping with his nature, remained a “pröbler” and designer. Looking back, it can be said that when the Züllig company was founded, a team of originals with unconventional working methods but a high degree of creativity was at work.
The Züllig company passed to the second generation of the family in 1955, with Dr. Hans Züllig having a strong influence on its development during this time and at times employing up to 200 people. Since 2024, Züllig has been part of the STEBATEC Group with around 40 employees.
