An excerpt of our enthusiastic customers

What pleases us the most: our customers say that working with COOLMASTER® is not only amazing but also fun – no matter how unattractive the cleaning job may be.

It’s just fascinating. Only the dissolved surface contamination remains. Sweep and you’re done.

Company

HaDo International GmbH was founded in 2015 by Harald Hartmann and Alexander Dohm.  With 35 years of experience in mechanical engineering, electronics and automation we developed our dry ice blasting machine COOLMASTER® – 100% made in Germany.

Our vision was to design a machine that could clean almost anything from airplanes to microelectronics with dry ice. Our top priorities were a reliable machine, flexible functionality, modern design and manufacturing in Germany.

Our COOLMASTER® Competence and training centre with development, sales, service, logistics and assembly is located in the Technology Park Tübingen-Reutlingen (TTR) in Baden-Württemberg. Sales and advice are provided by selected specialized dealers as well as directly by us.
