Industrial Applications

1. HVAC Fan Speed Control in Commercial Buildings

This inverter effectively controls the speed of large ventilation fans in commercial HVAC systems, allowing for optimized airflow and energy efficiency in response to building demands.

Problem Solved

Inefficient on/off or single-speed fan operation leads to wasted energy and suboptimal climate control. The inverter's variable speed control (0-550Hz V/f control) precisely matches fan speed to airflow requirements, reducing energy consumption and operational noise. The 3.0kW low overload rating is ideal for fan applications, and PROFINET/EtherNet/IP facilitates integration with Building Management Systems (BMS).

2. Conveyor Belt Systems in Automated Warehouses

The drive precisely controls the speed, acceleration, and deceleration of conveyor belts in automated warehousing and logistics, ensuring smooth material flow and preventing product damage.

Problem Solved

Conveyor systems require controlled starts, stops, and variable speeds for different loads or synchronization. The inverter's sensorless vector control (0-240Hz) provides accurate torque and speed for dynamic loads. The integrated Safe Torque Off (STO) function ensures immediate and safe stopping for maintenance or emergencies, meeting safety standards. Its IP20 rating supports cabinet mounting in industrial settings.

3. Pump Flow Regulation in Water Treatment Facilities

This inverter accurately regulates the flow rate of pumps in water treatment plants by adjusting motor speed, optimizing process control, and reducing wear on mechanical components.

Problem Solved

Fixed-speed pump operation in water treatment can lead to high energy consumption and pressure fluctuations. The inverter's variable speed capability (3.0kW LO for pump applications) enables precise flow regulation, eliminating the need for inefficient mechanical throttling valves. This saves energy and extends pump lifespan. The integrated Class A EMC filter minimizes electromagnetic interference in sensitive plant environments, and PROFINET communication integrates with SCADA systems.
