TÜV certified safety.
Signed, sealed and with the sense of responsibility.

Boilertubes are used in sensitive environments such as the energy sector as well as the chemical and petrochemical industry. We take this responsibility very seriously. That is one reason why BARTHEL is certified according to 
ISO 9001, ISO 14001 and OHSAS 18001. In addition we possess the essential specialist knowledge required for standards, audits and accreditations. Not least because TÜV CERT and BARTHEL have been a strong team for years, thus we are able to benefit from the experience of the largest national provider of certifications.
