About STIELOW

STIELOW GmbH Maschinen- und Apparatebau, based in Frankfurt am Main, has specialised in dehumidification, air humidification and water treatment since 1952 and is regarded as the first German machine factory for portable dehumidifiers. The product range comprises 40 models in over 300 equipment variants, including room dehumidifiers of the AIRDRY brand, construction dryers and industrial dehumidifiers of the HANDYDRY brand as well as JET humidification systems with diamond nozzle technology and water treatment plants. Research, development and design are carried out entirely in-house; production is done by hand with a high level of vertical integration at the Beselich-Obertiefenbach site (Limburg plant). Hot-dip galvanised sheet metal, Zinkor and aluminium sheets, stainless steel V2A as well as heat exchangers made of high-quality copper alloys are used. A special design department develops customised solutions, among other things with nozzles from the special fabrication programme. The products are manufactured in Germany and sold worldwide; spare parts are available for all JET products ever produced.
