Thank you very much for the great free heat exchanger software in Excel. We were able to recalculate a heat exchanger of our supplier. That was very helpful and easy and saved us a lot of money.

I use your free heat exchanger software for my lecture. One can thus represent the performance of heat exchangers very good. I use your “professional version” to explain the design of tubular heat exchangers to my students.
Prof. Dr. Jürgen Kuck

„Through an internet research to calculate the Reynolds number I came to your homepage and have to say that I am enthusiastic about the Excel program. It greatly facilitates my work with our microfluidic models of blood vessels.”
Dr. Torsten Gloe

“Your calculation tool is simply ingenious. I used it to prove the efficiency increase of an exhaust gas heat exchanger. In doing so, I was able to rely on measurement results from reality that allowed me to make comparisons. And I have to say that the results correspond to reality.”
