Company

Walter Herding set up a company in Amberg, Germany in April 1977. The firm manufactured complete dust extraction systems, but by 1982 Herding had outgrown its office and production facilities and had to move to a new location. Ever since, Herding has continued to expand the admin, R&D, production and logistic facilities at its Amberg North site.

International footprint

The signing of a licensing agreement with Eurotec/Nittetsu Mining in Japan was the first step on the road to international expansion (the agreement is still in effect). The first foreign subsidiary was established in Switzerland in 1988, and the first foreign production facility went into operation in the Czech Republic in 1991. The company now has eight independent subsidiaries and partnerships in nine other countries.

Products

The Herding success story really began with the invention of, and patent application for, a surface filtration process using rigid-body filter elements in 1980. The rigid body filter element went into volume production the following year. The Herding® sinter plate filter HSL was introduced five years later.

Other milestones include the introduction of the Herding® DELTA (1997) and the Herding® DELTA² filter (2003), development of the high-temperature Herding® ALPHA for applications up to 350/450°C (2000) and the HSL-C sinter plate filter for temperatures up to 100°C (2008).

Markets

Initially, Herding produced cloth and needle felt filters for mining and rock processing applications. As Herding continued to move up the performance curve with its rigid-body filters HSL, Herding DELTA and Herding DELTA², the company gained access to new markets. The target market now includes the basic materials industry, where it all started, as well as the food processing, pharmaceutical and renewable energy industries.
