Fan & Air Movement OEMs

From data centers to livestock barns, your fans run 24/7. The drive must be engineered for it.

If you manufacture fans — axial, centrifugal, mixed-flow, or EC fans — for ventilation, HVAC, agriculture, industrial processes, or any other application, the electronic drive and controller determine your product’s energy efficiency, noise profile, controllability, and field reliability. These are the attributes your customers select you for. KELD designs and produces custom fan drives and controllers for fan OEMs across a wide range of applications and power levels. We do not sell standard inverters. We engineer drive solutions that are matched to your fan aerodynamics, your motor, and your customer’s operating environment.

TYPICAL CHALLENGES WE SOLVE

  • Transitioning from fixed-speed AC motors to variable-speed EC or BLDC configurations without redesigning the entire product.
  • Achieving demanding noise and vibration targets through drive-level optimization (switching frequency, modulation strategy, acceleration curves).
  • Meeting ErP, DOE, and other energy efficiency regulations while keeping the BOM competitive.
  • Managing product families with multiple fan sizes, motor types, and voltage variants from a single electronics platform.
  • Serving diverse end applications — commercial HVAC, agricultural ventilation, tunnel ventilation, industrial cooling — each with different environmental and compliance requirements.

WHAT KELD BRINGS TO FAN OEMS

  • Purpose-built fan drive solutions optimized for your fan’s aerodynamic and motor characteristics.
  • Scalable drive platforms that cover your product portfolio: different power ratings, voltages, and communication protocols from a common architecture.
  • Co-engineering from concept through certification, with DFM and compliance built into the design from day one.
  • Production flexibility to handle the variety that fan OEMs deal with: many models, variable volumes, seasonal demand patterns.
  • Lifecycle management that keeps your electronics current as regulations tighten and components evolve.
