Developer: VdS Schadenverhütung GmbH

The HFC 227ea Calculation Program is a specialized engineering tool for designing and verifying clean-agent fire suppression systems using HFC‑227ea (heptafluoropropane, commonly known as FM‑200). Built to support VdS requirements and widely used international practices, it helps engineers determine agent quantities, design concentrations and hold times, and perform hydraulic calculations for pipework and nozzles. The software streamlines project documentation with clear, audit-ready reports to support approvals and compliance.
