We pride ourselves on our top-quality products. After all, they are the basis for our growth.

Our company is certified in accordance with DIN EN ISO 9001:2015. This ensures that we meet the agreed delivery deadlines by guaranteeing a high level of quality and reliable processes.

Our customers can be sure that they are getting top quality. After all, ABZ’s products are manufactured using only the finest components, and no product leaves the company without being tested. Each unit must undergo and pass extensive endurance tests and a complete functional check on our own test stands. The results of the checks are documented in a test report. This procedure not only ensures perfect results but also gives us the certainty that the unit is worthy of bearing the ABZ name.


All units comply with internationally recognised standards such as DIN, BS, ISO, VDE and IEC.

In addition, we are a specialist company as defined in § 19 of the German Water Resources Act (WHG) with authorisation to install tank systems.
