APPLICATIONS
INDUSTRIAL APPLICATIONS
SIRIUS 3RW soft starters are the optimal solution when direct-on-line or star/delta starting methods are unsuitable for three-phase motors. These intelligent soft starters provide superior control for applications where mechanical stress and electrical disturbances must be minimized.
- Conveyor Systems - Prevents belt slippage and material spillage during start/stop
- Pump Applications - Eliminates water hammer effect in piping systems
- Compressor Systems - Reduces mechanical stress during motor acceleration
- HVAC Systems - Smooth control for large fans and blowers
- Crushers & Mills - Gentle starting for heavy mineral processing equipment
- Mixers & Agitators - Controlled torque application for mixing equipment
- Elevators & Lifts - Smooth acceleration for passenger comfort
- Processing Lines - Prevents product damage in manufacturing processes
- Water Treatment - Controlled pump operation in filtration systems
- Material Handling - Reduces mechanical stress in crane and hoist systems
