Large rotary screw compressors 55 – 355kW

Nessco Pressure Systems offers rotary screw compressors from small to heavy duty capacity. Our large screw compressors range is available in sizes from 55 kW to 355 kW, including fixed speed and variable speed drive, and single and two-stage options.

Venti's range of singe stage, heavy duty industrial screw compressors are available in 75-355 kW models from Nessco Pressure Systems.

Venti’s Heavy Industrial, single stage rotary screw compressors are available in DCT (Fixed speed, single-stage rotary screw compressors with direct transmission) and DCT VSD (variable speed, single-stage rotary screw compressors with direct transmission).

Technical features

  • 75 – 315 kW
  • DCT and DCT VSD series offers energy efficiency and reliability for industrial use
  • Airend engineered for efficiency and durability – the optimised rotor profile, designed with cutting-edge fluid dynamics, minimises pressure drops within the system. This reduces energy consumption by 8%, delivering better power output.
  • Low rotation speeds extend the service life of the bearings, ensuring long-term reliability and performance.
  • The use of a low-speed motor (4/6 poles in the fixed-speed version) combined with appropriately sized rotary screws (max 1400rpm) ensures extended bearing life.
  • Speed control allows for precise detection of working pressure and motor speed, ensuring the optimal flow rate based on actual air demand, which results in significant energy savings.
  • The user-friendly KTronic 1000 touch screen panel provides full access to all functions, parameter settings, and diagnostics, helping to boost the compressor’s efficiency. It can also connect to a local area network (LAN), enabling you to monitor and manage the compressor from a remote PC or mobile device.
  • The cooling system features separate, individually managed coolers for air-to-air and air-to-oil systems, ensuring precise temperature regulation.
