Direct Drive screw compressor

Oil Injected Rotary Screw Compressor

Sigma brand rotary screw air compressors are known for their low maintenance and energy efficiency. Sigma brand rotary screw compressors come with 2 years of screw air end warranty. Screw Air Compressors are available in Standard Fix Models up to 300 HP and VFD (variable frequency drive) Models up to 100 HP.  We use PM (permanent magnet) Motors with VFD Models, which decrease energy consumption substantially to save even more energy as well as money.

Benefits of rotary screw compressors:
  • Our compressors contain premium quality Air end with high precision rotors, which operate at low RPM to provide the best efficiency.
  • Stable Air Flow Volume, Less wear Parts than Piston Compressor, High Reliability.
  • Simple mechanical structure has a low running cost, and provides a continuous 24 hours operation.
  • Less moving parts, integrated combination parts, lower failure, high protection grade.
  • Suitable for all main industry areas
Features:
  • 2 years of warranty for screw Air End.
  • Oil Cooler is Designed at 45° C ambient temperature which is suitable for Indian industrial circumstances.
  • Consumable cost is low up to 35% as compared to other leading brands.
  • Thermostatically operated fan motor.
Why Screw Air Compressor?
  • Super premium efficiency IE4 PM Motor
  • Vibration free quieter operation
  • Designed for hot indian climate.
  • Service friendly design.
  • Direct drive with low rpm.
  • Advance PLC for easy operation.
  • Lowest oil carry over.
  • Lowest life cycle cost.
One-To-One Gear Less Direct Drive:
  • At low speeds 2900 RPM large air end are more efficient than high-speed air ends.
  • Delivering more compressed air for the same drive power.
  • Lower speed means increased efficiency and durability with reduced compressed air cost.
  • Less wear & Less Maintenance Cost.
