DALGAKIRAN operates in more than 130 countries worldwide and has more than 100 authorized dealers in Turkey.
SCREW BLOCKS
- 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.
- There is a new generation of ball bearing tilt system with 3 times more load carrying capacity than standard designs.
- With the optimal lobe combination, the new rotor profile allows less air escape and reduces torque requirements, resulting in a significant reduction in energy costs.
- Gearboxes are used by American Gear Manufacturers Association (AGMA) standards.
MAIN MOTOR AND DRIVE SYSTEM
- High efficiency 380V / 3 phase / 50Hz IE2 IP55 motors are used as standard in DVK series.
- The driving of the screwdriver gearbox shaft is carried out directly between the screw block and the main motor via a flexible coupling with a 1: 1 transmission.
- Since there are no belt-transfer losses in the direct coupling system, it is up to 3% more efficient than the belt-pulley mechanism and there is no maintenance problem.
- By not using the belt-pulley mechanism, noise and vibration levels are noticeably reduced.
AIR SUCTION SYSTEM
- 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.
AIR / OIL SEPARATOR
- 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.
SAFETY AND WARNING SYSTEMS
- Main motor and fan motor overcurrent control
- Phase sequence, deficiency and imbalance control

ELECTRICAL SYSTEM
- It has an LCD control panel that shows the operation and service functions in a way that everyone can easily understand.
- Mechanical safety systems are supported by PLC controlled safety switches and relays.
- In electric panel design, brands which offer quality products in world standards have been preferred.
CANOPY DESIGN
- Canopy design requiring minimum working area
- Ergonomic design that provides ease of maintenance and allows easy intervention at every point of the machine
- Service closures that can be easily removed
- Vibration chocks made of special rubber that eliminate vibration and the problems it may cause
