Equipment Features
- Stable constant-pressure output Integrated VFD and pressure tank maintain steady outlet pressure regardless of flow fluctuations, ideal for filling and spraying.
- Flexible pressure adjustment Output pressure can be adjusted flexibly according to process demands via the frequency converter.
- Energy-saving operation Variable frequency drive matches motor speed to real-time demand, significantly reducing energy consumption.
- Smooth soft start Soft start-up reduces mechanical and electrical shock, extending equipment service life.
- Food-grade hygienic design 304 / 316L stainless steel wetted parts complying with food hygiene standards and CIP / SIP processes.
Working Principle
A pressure sensor continuously monitors the outlet pressure and feeds the signal to the variable frequency drive. The VFD automatically adjusts the motor speed to keep the pressure at the set value, while the pressure tank absorbs short-term fluctuations. Together they maintain a stable constant-pressure supply even as downstream demand changes.
