Water treatment and wastewater facilities operate continuously under demanding conditions.
Large pumps, blowers, and auxiliary heating systems must start reliably, run efficiently, and withstand high humidity and frequent load changes.
High inrush current during motor starting
Mechanical stress on pumps, pipelines, and valves
Risk of water hammer
High energy consumption under partial load
Harsh, humid operating environments
Cost-sensitive projects with long service life requirements
Raw water intake pumps
Booster pumps and distribution pumps
Sewage lifting pumps
Sludge transfer pumps
Aeration blowers
Chemical dosing and heating systems
Reduced starting current and torque shock
Prevention of water hammer
Step-less acceleration and deceleration
Comprehensive motor protection functions
Lower installation and maintenance cost compared to VFDs
Precise speed control for pumps and blowers
Energy-saving operation under variable load
Soft start and soft stop to reduce hydraulic shock
Improved process stability
