Detailed Description
Application: APl series is an automatic constant-pressure (level, flow) control device based on the high-intelligence J9Zn inverter. By varying pump speed it realizes automatic regulation of pressure, flow, level and temperature with high energy efficiency.
Main Features:
- Power range: 0.75-80kW, three-phase 380V
- Integrated design without external switching equipment
- Energy saving up to 20-40%
- Multi-pump rotation and automatic switching
- Automatic transfer to mains operation on inverter fault
- Suitable for water supply systems, fire-fighting systems, sewage treatment, agricultural irrigation and spray systems
Widely used in industrial, municipal, residential and fire-fighting water supply and constant-pressure systems.
