Quality is very important for the Langen-Feuerungsbau company. For over 50 years the name Willy Langen Feuerungsbau GmbH has stood for high quality components for all kind of furnances.

We focus on our proven Quality-Management-System DIN ISO 9001:2008 at all our production and workflow, which is constantly updated and which is adapted to the growing requirements.

Every production step from the incomming inspection over SPC-Inspection in the current production to the point of EMPB is recorded and documented in our company.

For this we turn our attention especially to the motivation and advanced training of our staff.

All our welder operations for example are realised only from skilled personal which have passed succesfully the welder's performance qualification according to DIN 287.

Quality isn't a coincidence!

Certified DIN ISO 9001:2008

Quality is our passion!
