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.

I really like your free heat exchanger program in Excel. In my lectures, it helps me to explain heat exchangers to the students in a more visible way. Particularly interesting is that it very quickly gets the temperature profiles by changing the parameters. Thus one can "play around" with these parameters and get a good feeling on their affect.

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.

With your help and patience, we made a major step forward in the dimensioning and design of a new heat exchanger type. I am happy to utilize your services for future projects again.

Really a helpful tool for those who want to calculate heat exchangers! Very clear and easy to understand!

With the help of your software, we were able to demonstrate that the planners had used unrealistic values for the design of the heat exchanger. In designing the new heat exchanger I could give the planner a recommendation on the heat exchanger surface based on your software. This was confirmed after the installation. Everyone was happy and I now have a better understanding of the heat exchangers processes.
