VFD

In order to modify the discharge pressure and flow rate, the PMSM's spinning speed is controlled by a VFD (variable frequency drive).

  • Large flow turndown range of 45100% is possible.
  • Suitable for large WWTPs with frequently changing flow rates

Characteristics

Controller

Through PLC and a touch screen, operating conditions may be easily controlled and real-time monitored and diagnosed.

various operating modes that can be customized to the needs of the user (constant speed, constant pressure, constant flow, and DO link).

Remote supervision and control using a variety of protocols (including MODBUS, PROFIBUS, ETHERNET IP, and hard wire) many languages (including English and Korean).

Package

  • Eliminating the gearbox and lubrication system (Oil-Free) prevents environmental contamination.
  • Due to the innovative cooling architecture, the blower room does not require additional ventilation.
  • Compact design and reduced installation costs with all-in-one package.
  • Plug & Play functionality.
