About us

Company details

Origins

LWN Lufttechnik Ltd was borne out of long-standing, hands-on experience, hard work and specialist knowledge among the company’s acting partners. Founded in 1997, LWN quickly became the specialist supplier of process air technology to the German glass industry. The company launched with four partners and six employees.

Milestones

In 2002, LWN’s planning, construction and production divisions were merged and a single production site for system components was established in Wilsdruff, near Dresden. The amalgamation meant the company could provide clients with an exceptional standard of service. Through flexibility and independence, the company made a name for itself as a trustworthy firm to do business with, both inside Germany and beyond. More and more clients were won across Europe and the number of employees trebled to 18. LWN Prozesstechnik Ltd was launched in 2003, providing clients with a one-stop-shop for ready-to-use air technology systems, complete with electrical engineering and automation.

Vision

LWN – now with 60 employees - is working with the German and international container and flat glass industries to develop intelligent solutions, which raise product quality for clients, increase the service life of systems and save energy. Offering reliability, comprehensive service skills and product and technological innovation, LWN is a company of the future.
