Variable Frequency Drive (VFD) and Harmonic Filter Supply

The contract solicits the supply of a Variable Frequency Drive and harmonic filter system designed to achieve at least 98 percent efficiency and maintain a power factor of 0.95 or higher, ensuring optimal energy performance and compliance with stringent electrical standards. The equipment must operate effectively with motor lead lengths up to 250 feet without requiring additional harmonic filtering, which demands advanced design and built-in mitigation capabilities to prevent waveform distortion and system stress. Full technical documentation, including certifications verifying performance claims and regulatory compliance, is required alongside integration support to ensure seamless installation and compatibility with existing infrastructure. This subcontract, issued by the Massachusetts Department of Public Works under NAICS code 335313, is targeted toward vendors capable of delivering high-performance power systems for municipal applications. The place of performance is designated as Needham, Massachusetts, with a response deadline of July 21, 2026. While no specific set-aside provisions are specified, the solicitation emphasizes technical rigor and real-world operational reliability, expecting suppliers to demonstrate proven experience with similar high-efficiency, long-lead VFD systems in public works environments.
