Energy Efficient VFD Screw Air Compressors in Kolkata

Industries in Kolkata face rising power costs, fluctuating air demand, and frequent load changes across daily production cycles. Fixed speed compressors waste energy during partial load operation and struggle to match real time air demand. This leads to higher electricity bills, pressure instability, and avoidable wear on components.

Frank Compressors manufactures VFD screw air compressors under ISO 9001 certified quality systems. Our variable frequency drive technology adjusts motor speed based on actual air demand. This ensures stable pressure, reduced energy use, and longer equipment life for continuous industrial operations across Kolkata and West Bengal.

Energy Savings During Partial Load Operation

VFD screw air compressors match air output to actual demand. This reduces power consumption during low load periods and cuts electricity costs significantly.

Stable Pressure for Sensitive Processes

The variable speed drive maintains constant pressure without spikes or drops. This protects tools, improves product quality, and reduces air leakage.

Reduced Mechanical Stress

Soft start and controlled speed changes reduce stress on motors and screw air ends. This extends service life and lowers maintenance frequency.

Key Features of Frank VFD Screw Air Compressors

  • The low RPM heavy duty screw air end delivers higher efficiency with low noise and strong energy savings.
  • he microprocessor based control system with a touchscreen shows all operating conditions and maintenance schedules for reliable performance.
  • Large oil filters and advanced air oil separators keep oil carryover below 3 PPM and extend service intervals.
  • The compressor meets low noise standards as per PN8NTC 2.3 measured at one meter distance in free field conditions.
  • A larger air and oil cooler with a high capacity cooling fan maintains low outlet air temperature.
  • The design supports tough environmental conditions and provides ample internal space for easy maintenance access.
  • Fewer moving components improve reliability and reduce mechanical wear.
  • Energy savings over three years exceed the initial equipment investment.
  • Trusted branded inverters from globally recognized manufacturers ensure stable and efficient operation.
