Variable Frequency Drives - VFDs

Optidrive E3 General Purpose Drive - 2025

💧 Smarter Pumping Solutions for Water and Wastewater Systems 💧

Municipal water supply networks and wastewater facilities rely on variable frequency drives (VFDs) to deliver precise speed and torque control across pumps of all sizes. VFDs adjust motor output dynamically to match real-time demand, reducing energy consumption and extending pump lifespan. Advanced features like blockage detection and cleaning, dry run protection, and pump stir cycles ensure uninterrupted service even in challenging conditions.

Supporting induction, permanent magnet, and synchronous reluctance motors, variable frequency drives enable variable and constant torque operation, high efficiency, and smooth flow regulation. Integrated bypass capability for direct-on-line (DoL) operation keeps critical infrastructure running in the event of a fault. Whether modernizing a treatment plant or automating a multi-pump water station, VFDs deliver the reliability and energy savings today’s municipal and industrial systems demand. 🌎⚙️

🏢 Smarter Motor Control for Efficient Buildings ⚙️

From cooling towers and chiller pumps to large ventilation fans and booster systems, variable frequency drives (VFDs) deliver precise speed, torque, and power control essential for modern building automation. Designed for both variable and constant torque loads, VFDs dynamically adjust motor operation to match demand in real time, driving significant energy savings and reducing mechanical wear. Built-in features such as fire mode operation, BACnet and Modbus RTU communication, and advanced bypass integration for critical Direct-on-Line (DoL) switchover ensure reliable performance in even the most demanding applications.

With low harmonic design, quiet high-frequency switching, and built-in EMC filters, VFDs simplify installation and improve overall building performance. Whether you operate a residential high-rise, commercial complex, or mission-critical facility, variable frequency drives help achieve energy targets, lower costs, and maintain comfortable environments year-round.

❄️ Drive Maximum Efficiency in Refrigeration & HVAC Systems ❄️

Variable frequency drives are transforming compressor, pump, and fan applications, delivering precise control of motor speed, torque, and power consumption across refrigeration and HVAC systems. By continuously modulating compressor speed to match real-time cooling demand, VFDs improve system performance, extend equipment life, and achieve significant energy savings. With features such as soft start, configurable start-up profiles, and wide-speed operating ranges, they reduce wear and improve temperature stability in chillers, heat pumps, and condensing units.

Supporting induction, permanent magnet, and BLDC motors, Invertek Drives Coolvert series offers compatibility with high-efficiency rotary and scroll compressors, along with integrated crankcase heating, oil return cycles, and advanced safety protections. These VFDs also ensure compliance with stringent EMC standards and feature Safe Torque Off (SIL3), low harmonic emissions, and precise modulation up to 500 Hz output frequency.

Whether for commercial refrigeration, industrial chillers, or high-efficiency HVAC systems, variable frequency drives deliver the performance and reliability to keep operations efficient and cost-effective.
