General Information

INVERSYS PLUS series screw air compressors are manufactured to work successfully in different application areas. High performance and quality parts used in production and installation of products designed to be easily adapted and learnt by users at all levels provide long maintenance intervals and consequently low operating expenses.

Our products are manufactured to work successfully in different application areas. High performance and quality parts used in production and installation of products designed to be easily adapted and learnt by users at all levels provide long maintenance intervals and consequently low operating expenses.

  • Designed with the benefits of the latest technology such as “Computational Fluid Dynamics (CFD)" and “Finite Elements Method (FEM)” and new generation screw blocks manufactured with high-end manufacturing techniques, it provides high efficiency, robustness and low energy consumption with its new rotor profile and lobe combination.
  • It has a new generation roller bearing system with the capacity to carry 3 times more load than standard designs.
  • With the optimal lobe combination, the new rotor profile allows for less air escape and reduces the need for torque, resulting in a significant reduction in energy costs.
  • In the INVERSYS PLUS series, high efficiency and high speed, IE2 energy class, inverter-suitable IP55 motors are used as standard.
  • Inverter equipment having low energy loss and high performance unlike star-delta and soft-starter motor riding methods prevents the engine from being worn with unnecessary stop starts and provides serious energy gains by adjusting the engine speed according to the desired flow rate.
  • The propulsion of the screw rotor shaft, is achieved by 1:1 transfer with flexible coupling between screw block and main motor in direct coupled way.
  • Unlike other power transmission systems with direct coupled transfer system, mechanical losses are minimized and energy savings are achieved.
  • Noise and vibration levels are reduced to noticeable levels by not using the belt-pulley mechanism.
  • It has been developed with high-end engineering software that includes versatile analysis such as FEM and "Fluid Dynamics".
  • The simple design of the suction regulator consisting of three control block units, a solenoid valve and a control cylinder makes periodic maintenance easy to perform.
  • The suction regulator provides reliable operating performance of up to 8000 hours with the use of premium materials in its production and the number of seals reduced in its design.
  • The fact that the suction valve can take a full upright position when open, and that the suction valve with almost straight and one-way airflow has an air outlet area increased by 25% with new profile design promises low pressure drop and high performance.
  • Two-stage air suction filter system consisting of interchangeable micro glass fiber front panel filter and cassette type air inlet filter with interchangeable paper element provides fresh air for screw block and cooling system, minimizing problems that may occur in dusty environments.
  • It performs a more efficient separation in lower volume with deep-bearing interlocking separation layers.
  • It has a performance design that provides 3-stage separation.
  • After separation, fat resolution less than 3 mg/m3 is obtained.
  • Aluminum combi boiler cooler with long-lasting Bar/Plate system guarantees trouble-free operation in all conditions.
  • The four-way thermostatic valve prevents water condensation at low temperatures, extending oil life and eliminating the risks of failure.
  • The new wing profiles are supported by silent and effective axial fans operated by an electric motor independent of the main engine.
  • It has new fan slots that allow easy cleaning and service in a short time.
  • Variable speed controlled fans ensure effective cooling regardless of the main engine and keep the compressor at optimal operating temperature and thus air is compressed with high performance and efficiency. (Except for INVERSYS+ 5P-22P and water-cooled models)
