Industrial Applications

1. Conveyor Belt Systems in Manufacturing

This drive can precisely control the speed of conveyor belts in manufacturing and logistics. The 11 kW power rating is suitable for medium-duty conveyors.

Problem Solved

Enables soft start/stop to reduce mechanical stress and wear on the conveyor system, improving operational lifespan and reducing maintenance. Variable speed control optimizes material flow and throughput for different product types or production stages. The integrated Safe Torque Off (STO) ensures safety during maintenance or emergency stops, preventing unexpected motor restarts.

2. Pump Control in HVAC or Water Treatment

The SINAMICS G120C can efficiently regulate the speed of pumps in HVAC systems for climate control or in water treatment plants for flow management.

Problem Solved

By adjusting pump speed based on demand, it significantly reduces energy consumption compared to constant-speed operation with throttling valves. This also minimizes wear on pipes and pumps, extends equipment life, and maintains precise pressure or flow rates. The IP20 rating is acceptable for installation within an enclosed control cabinet in a plant room.

3. Fan and Blower Control in Industrial Ventilation

This compact inverter is well-suited for controlling industrial fans and blowers, optimizing ventilation and air circulation in factories, warehouses, or exhaust systems.

Problem Solved

Provides precise air flow control to maintain desired environmental conditions, save energy, and reduce noise. The ability to vary fan speed dynamically prevents over-ventilation, leading to energy savings, and improves air quality management. The integrated Class A filter helps to ensure compliance with EMC requirements in industrial environments.
