From planning, design, production and assembly to after-sales service. We support you in all phases of the project.


High energy prices lead to higher production costs.
With NET, your energy costs can be significantly reduced through heat recovery.
We are happy to advise you.

Flue gas measurement

We offer precise volume flow measurements, which show very accurately how large the flue gas volume
is dependent on the temperature and the cross-section in the flue gas system.

Concept development

We create an individual concept for heat recovery, taking into account operational safety and economic efficiency. Heat exchangers are custom designed and engineered to fit your plant and needs. All necessary components of the flue gas path are assembled into one system. For you, this means avoiding sources of error in all phases of the project!


Our heat exchangers are manufactured exclusively in Germany in compliance with CE standards and are made of high-quality stainless steels. Standard materials are: 1.4404, 1.4571.
For particularly high requirements we use materials with the alloy 1.4539 and 1.4828.


With our comprehensive network of installation partners, we offer you the possibility of having your system installed anywhere in Germany, but also in neighboring countries.
Here, too, we guarantee at all times that the technical rules, standards and regulations are complied with.

After Sales Service

Whether full service, maintenance, inspection, repair or special services.
Our expert staff will be happy to assist you with any questions you may have about your heat recovery system around the clock!
