Delta Inverter for inverter chillers

Industrial-grade Delta or Mitsubishi VFDs, providing smooth and stable frequency control.

Standard Features

  • Inverter-Driven Compressors: Powered by world-class variable frequency scroll or screw compressors. Featuring stepless capacity modulation (25%-100%), they automatically adjust motor speed to match your exact thermal load, eliminating energy-wasting ON/OFF cycles and maximizing part-load efficiency (IPLV).
  • Premium VFD Technology: Equipped with top-tier Variable Frequency Drives from globally trusted brands like Delta or Mitsubishi. This ensures a smooth “soft start” with ultra-low starting current, significantly reducing mechanical wear and electrical stress on your facility’s power grid.
  • Variable Speed EC Fans & Condensation: Features a high-efficiency finned-tube condenser array paired with advanced EC (Electronically Commutated) axial fans. The fan speed dynamically syncs with the compressor load, providing exceptional heat dissipation while drastically reducing noise and fan power consumption.
  • Next-Generation PLC & PID Control: A built-in Siemens microprocessor continuously monitors dynamic loads. Combined with advanced PID algorithms, it guarantees ultra-precise water temperature regulation (up to ±0.1∘C to 0.5∘C variance) for highly sensitive industrial processes.
  • High-Performance Shell-and-Tube Evaporator: Designed with heavy-gauge materials to provide superior heat transfer rates, excellent resistance to fouling, and simplified maintenance for continuous, non-contaminating fluid cooling.
  • Comprehensive VFD & System Protection: Built-in safeguards include standard high/low pressure and flow switches, plus dedicated VFD protections such as over-voltage, under-voltage, phase loss, and inverter overheating protection.
