Josef Kränzle GmbH & Co. KG is a manufacturer of high-pressure cleaners, industrial vacuum cleaners and manual sweeping machines headquartered in Illertissen. The family-owned company, founded in 1974 by Josef Kränzle, develops and manufactures around 70 % of the components of its products at its own site, including high-pressure pumps with pump heads made of forged special brass, ceramic-coated stainless steel plungers and Roto-Mold plastic chassis. Series production comprises more than 100,000 high-pressure cleaners per year, of which around 75 % are used commercially. Every machine is tested by hand before shipping. The products are distributed worldwide via the specialized trade as well as the company's own sales companies in Switzerland and Poland. Customers include trades, agriculture, automotive, industry and building cleaning.
