Long tradition

We are the technology successor to Fischtechnik Fredelsloh. Its founder, who died far too early, Dr. Dipl. Ing. agr. Gerhard (James) Müller † and fish breeder Helmut Müller † are still known to many. We can therefore look back on more than 40 years of manufacturing tradition.

In particular, our fish sorting machines have now been sold more than 2000 times in more than 70 countries worldwide. Many of the old machines are still running today and of course we still supply all customers with the desired spare parts.

But we haven’t stood still technologically and of course we are constantly adapting the production and properties to the new circumstances.

Extended portfolio

The core competencies in our workshop are the processing of aluminum and stainless steel. It therefore made sense to offer such products for home, garden and parks. In this respect, we serve several markets today and are happy when these innovative products find your approval.

With our new shop, we want to pay tribute to convenience and make shopping quick and easy.

But we are still a manufactory and also serve custom-made products and special requests. We weld fire brigades and ambulances with aluminum superstructures in the event of repairs, which is not uncommon. If you want aluminum welded (e.g. engine or gearbox housing), you can also contact us.
