DALGAKIRAN promises suitable, trouble-free and high performance for every kind of application with its INVERSYS PLUS series oil-injected rotary screw air compressors. Manufacturing and assembly of every single part of these compressors, in which latest engineering software is used during design and analysis phases, is realized considering international quality standards.
EASE OF USE
INVERSYS PLUS series compressors are manufactured to be employed different areas of application without any performance loss. High performance and quality grade parts used in manufacturing and assembly of these products which are designed to make users in every level of experience easily adapt and learn, provide long maintenance periods and thus, low operating costs as a result.
WIDESPREAD AFTER-SALES SUPPORT SERVICE
As having operations in more than 100 countries around the globe and possessing more than 150 authorized dealers in Turkey, DALGAKIRAN offers reliable use of the products to its customers with its after-sales support network.
ROTARY SCREW BLOCK
- New generation rotary screw blocks, designed with latest technological tools like “Computational Fluid Dynamics (CFD)” and “Finite Element Method (FEM)” and manufactured using high-end manufacturing techniques, provide high efficiency, durability and low energy consumption with new rotor profile and lobe combination.
- Block contains new generation bearing system in which the bearings with three times more load carrying capacity than the standard designs are employed.
- As new rotor profile permits less air leakage occurrences with optimal lobe combination and decreases the torque needed to operate, less energy is needed to operate that leads to less operating costs.
MAIN MOTOR AND DRIVE SYSTEM
- High efficiency IE2 class IP55 motors working with 380V/3 phase/50Hz power inlet and suitable for invertor application are used as a standard in INVERSYS PLUS series.
- Aside from driving motor with star-delta connection and soft starter, motor speed is adjusted according to the airflow demand by the invertor which adjusts the supply frequency of the motor leading to less energy consumption and high performance. With this speed adjustment, motor is not forced to start and stop according to airflow demand which lessens its lifecycle so that serious energy savings can be achieved.
- Driving the rotor shaft is realized by direct-drive mechanism with a flexible coupling placed between rotary screw block and main motor shaft.
- As the mechanical transmission losses are less, the direct-drive mechanism is approximately three percent more efficient than the belt-pulley mechanism and it is mostly maintenance-free.
- In the absence of belt and pulley, noise and vibration levels get noticeably lower.
AIR SUCTION SYSTEM
- It’s developed by using sophisticated engineering analysis tools like FEM and “Fluid Dynamics”.
- With its simple design consisting of three control block units, a solenoid valve and a control cylinder, periodical maintenance services of the suction regulators are easily and quickly realized.
- First class materials used in the suction regulator manufacturing and lessened seal amounts provide reliable operating performance up to 8000 hours.
- With the suction valve which gets fully perpendicular position when it’s opened, almost straight and unidirectional airflow, increased air outlet area by %25 with the new profile design, the suction regulator promises low pressure drops and high performance.
- Double stage air suction filter system consisting of replaceable front-panel filter from micro-glass fiber, replaceable cassette type air intake filter with paper element minimizes the problems caused in dirty environments by providing clean air for the rotary screw block and the cooling system.
AIR / OIL SEPARATORS
- More effective separation is realized at less volume with the progressive type, deep bedded and meshed separation layers.
- These separators have high performance design providing three-stage separation.
- Less than 3 mg/m3 of oil density is transferred with compressed air during separation.
- Aluminum combi cooler with long-life Bar/Plate system guarantees trouble-free operation at all kinds of conditions.
- Four-way thermostatic valve lengthens the lifecycle of oil and eliminates the risks of malfunctioning by preventing condensation at low temperatures.
- New blade profiles are supported with silent and effective axial fans.
- New fan seats are employed to provide easy access and short time periods for clean-up during maintenance service.
- Effective cooling is achieved with variable speed drive (VSD) fan motor. (except INVERSYS+ 5P-18P and water cooled models)
