Dedicated Engineering HVAC Associates
Your Partner in Variable Frequency Drive (VFD) Solutions for the HVAC Market
Why Variable Frequency Drives?
Variable Frequency Drives (VFDs) have become the standard for modern HVAC systems. By controlling motor speed and adjusting to real-time demand, VFDs deliver efficiency, comfort, and reliability across a wide range of applications.
- Energy savings: Reduce electrical consumption by running motors only as fast as needed, lowering both operating costs and peak demand charges.
- Comfort & stability: Smooth ramping and precise control of airflow and waterflow keep indoor environments steady, quiet, and efficient.
- Extended equipment life: By reducing mechanical stress on motors, pumps, and fans, VFDs help equipment last longer and minimize maintenance needs.
- Code compliance & sustainability: VFDs support energy codes, green building standards, and sustainability targets for new and existing facilities.
