HVAC & Climate System Manufacturers

Your system integrates fans, compressors, valves, and sensors. The electronics must tie them all together.

HVAC system manufacturers face a unique integration challenge: their equipment combines multiple subsystems — fan drives, compressor control, valve actuation, sensor networks, and user interfaces — that must work together seamlessly. The electronic controls at the center of this system determine energy efficiency, comfort performance, and field reliability. KELD serves HVAC OEMs with both drives and controllers: variable speed drives for fans and compressors, intelligent temperature and climate controllers, and integrated solutions that combine control and power in a single platform.

TYPICAL CHALLENGES WE SOLVE

  • Integrating multiple control functions (fan speed, compressor staging, valve actuation, defrost management) into a single electronics platform.
  • Connecting to building management systems via Modbus, BACnet, or proprietary protocols.
  • Meeting evolving energy efficiency standards (ErP, DOE) across European and US markets.
  • Managing product families with multiple capacity ratings, refrigerant types, and regional configurations.
  • Balancing performance, cost, and compliance in a highly competitive market.

WHAT KELD BRINGS TO HVAC MANUFACTURERS

  • Custom controllers and drives designed for the specific architecture of your equipment — not adapted from generic platforms.
  • Integrated solutions: combined drive-and-control boards that reduce BOM cost, PCB count, and assembly complexity.
  • Co-engineering support from system architecture definition through certification and production.
  • Production flexibility that accommodates the model variety and seasonal demand patterns inherent in HVAC manufacturing.
  • Lifecycle continuity: proactive management of component changes, regulatory updates, and product evolution.
