Features & Capabilities

System Syzer is an HVAC tool that helps with piping system design. The application is based on the original plastic wheel calculator by designed by Gil Carlson of Bell & Gossett. It was first introduced in 1963 and has since been distributed to well over a hundred thousand engineers and tradesmen.

The tool is made up several different calculators. There is a calculator for friction loss and velocity through pipe based on your fluid conditions. Use it to determine the relationship between fluid temperature, system flow and heat/cooling load. There is a Cv tool that can help in multiple ways.

We have also bundled the Circuit Setter® / Triple Duty Valve calculator that is very handy for balance contractors. Use it during design to help predetermine valve settings and out in the field to determine flow through the valves based on pressure drop readings.

This app is something I have all of my field personnel download onto their phone. Helps eliminate pipe sizing questions and provides basic pressure drop calculation assistance.

Depending on if you reset the values each time correctly this app will give you a completely wrong answer based on the printed charts. Also even when it does seem to calculate correctly, there is still some degree of discrepancy with the printed charts. It has been this way for years, and I finally decided it is time to stop using the app altogether for circuit setter balancing.

This app worked great until I updated my iPhone operating system to iOS version 14.5. I am waiting for the app web developer to fix the bug so I can once again use it.
