Progress is in the air


At ZLT GmbH – part of Aldes group, founded in 1925 – we are convinced that the meaning behind our actions must serve as a veritable breath of fresh air, providing the impetus for everything we do.

We work with respect, trust and commitment to accomplish our mission of creating healthier indoor spaces while fulfilling our social and environmental responsibilities. We are well aware that our collective energy is amplified when we all pull together, in the same direction. All around the world. By turning each individual’s sense of commitment into a collective voice, we are working to improve indoor air quality.
