DVK Series Rotary Screw Air Compressors 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 • 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 are used as a standard • Driving the rotor shaft is realized by a belt-pulley mechanism placed between rotary screw block and main motor and selected considering a suitable transmission ratio. • Belts are chosen by considering the working life of • The pulley with bushing eases assembly-disassembly • With easy adjustment of belt tension, continuously efficient operation of the compressor is secured. COOLING SYSTEM • Aluminum combi cooler with long-life Bar / Plate system guarantees trouble-free operation at all kinds • 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 operated by a standalone electric • New fan seats are employed to provide easy access and short time periods for dean-up during maintenance • 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 • 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. • 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.
