General Information

INVERSYS PLUS series screw air compressors have been produced in order to work successfully in different application areas. High performance and quality parts used in the manufacture and assembly of products designed to be easily adaptable and user-friendly at every level provide long maintenance intervals and consequently low operating costs.

DALGAKIRAN operates in more than 130 countries worldwide and has more than 100 authorized dealers in Turkey.

New generation of screw blocks, designed with the benefit of the latest technology such as “Computational Fluid Dynamics (CFD)” and “Finite Element Method (FEM)” and manufactured with advanced manufacturing techniques, new rotor profile and lobe combination provide high efficiency, It offers consumption.

In the INVERSYS PLUS series high efficiency and high speed, IE3 energy class, IP55 engines suitable for driving with inverter are used as standard.

Unlike star-triangle and soft-starter motor drive methods, low-energy loss and high performance inverter equipments provide a significant energy savings as well as avoiding unnecessary stop-and-start wear of the motor by adjusting the motor speed according to the desired flow capacity.

The drive of the screw rotor shaft takes place directly between the screw block and the main motor with a flexible coupling with 1: 1 transmission.

Unlike other power transmission systems, mechanical losses are reduced to the minimum level by means of a direct coupling transfer system to save energy.

By not using the belt-pulley mechanism, noise and vibration levels are noticeably reduced.

FEM and “Fluid Dynamics”.
The simple design of the suction regulator, which consists of three control block units, a solenoid valve and a control cylinder, ensures that periodic maintenance is easy.
Suction regulator provides reliable working performance up to 8000 hours with the use of first class materials in manufacturing, reduced number of gaskets in design.
The suction valve promises low pressure drops and high performance with a fully upright position, almost straight and unidirectional air flow, a new profile design and a 25% increase in air exit area when the suction valve is open.
The two-stage air intake filter system, consisting of a replaceable microfiber glass front panel filter and cassette-type air inlet filter with interchangeable paper elements, minimizes problems that may occur in dusty environments by providing fresh air for the screw block and cooling system.

It achieves a more efficient decomposition at a lower volume with deep-bedded separating layers.
It has a performance design that provides 3-step decomposition.
After separation, a low oil solubility of 3 mg / m3 is obtained.

The aluminum combi cooler with long-lasting Bar / Plate system guarantees trouble-free operation in all kinds of conditions.
The four-way thermostatic valve prevents water condensation at low temperatures, extending oil life and eliminating risk of failure.
The new wing profiles are supported by quiet and efficient axial fans driven by a main motor independent electric motor.
It has new fan nests which are easy to clean and provide service in a short time.
With variable speed control fans, independent of the main motors, effective cooling is ensured so that the compressor is kept at the optimum working temperature, thus compressing the air with high performance and efficiency. (Except INVERSYS + 5P-22P and water-cooled models)
