Initial release of the Bell & Gossett SystemSyzer, a system sizing tool for HVAC and plumbing professionals.
HVAC piping system design tool with friction loss, Cv, and valve calculators.
SystemSyzer is an HVAC tool that helps with hydronic piping system design. It's based on the original plastic wheel calculator designed by Gil Carlson of Bell & Gossett, first introduced in 1963 and used by well over a hundred thousand engineers and tradespeople since. The app brings several calculators together in one place: • Friction loss and velocity through pipe based on your fluid conditions • The relationship between fluid temperature, system flow, and heating/cooling load • A Cv (flow coefficient) tool to assist with valve sizing in multiple ways • The bundled Circuit Setter / Triple Duty Valve calculator, handy for balancing contractors: predetermine valve settings during design, and determine flow through valves from pressure-drop readings in the field • Support for PEX pipe Whether you're at the desk during design or out in the field, SystemSyzer puts trusted Bell & Gossett sizing references at your fingertips.
