We require first class quality of our products and
their long life. Quality care does not end with
precision production. We think of the TZB designers,
who we also provide expert advice and
technical support when designing a suitable heater or
a water tank, storage tanks, pressure vessels and
other products. Expert support is ensured by the experienced
and trained workers.
