Our flagship: The Quick Connect System As a specialist in the design and manufacture of components for sophisticated chemical handling, we offer high-quality products for numerous industries. The focus is on our Quick Connect system, which we originally developed in 1994—together with our partner Riedel de Haën (now operating as Honeywell Specialty Chemicals Seelze GmbH). The successful concept of our Quick Connect system has been refined over the years and today represents one of the most important industry standards in chemical handling. Through our in-house plant and equipment engineering, we can offer a customized complete package, including, for example, chemical cabinets, tanks, heat exchangers, and process technology with dispensing systems. Experienced partner for all industries High-quality products made in Germany With in-house production of dip tubes, dispensing heads, as well as custom-made components and their assembly, KTJ stands for quality “made in Germany.” With our team of dedicated, confident and well-trained employees and the modern CNC machines, we guarantee you distinctive product quality. Thanks to decades of experience in the processing and assembly of plastics, we can offer entire cabinets for safe chemical handling in addition to our standard products such as the dip tubes and dispense heads.
