Proventia Thermal Components – integral insulation technology

Proventia Thermal Components is a multi-layered light insulation technology that also protects temperature-sensitive components in the engine compartment by keeping the heat in the exhaust pipeline and boosting the performance of the exhaust system. Proventia integral insulation is an ideal choice for any application that requires high insulation efficiency combined with low weight and easy shaping, e.g. exhaust manifolds, turbo insulation, complete exhaust pipelines and systems.

We also offer our customers a complete set of modular equipment for producing thermal components.
