[Get started for free](https://www.hysopt.com/company/contact/trial) ## Still Have Questions? Can Hysopt Calculator work with custom component libraries? Yes. It supports both standard and user-defined components, including valve curves and manufacturer specs. Is it only for commissioning? No—it’s used from system sizing through to BOM export, making it ideal for full lifecycle design workflows. How does it differ from Hysopt Designer? Designer is used for schematic-level system modeling and performance validation. Calculator is used for fast sizing, equipment selection, and commissioning prep.
