    DAV II 2-Stage PM VSD Energy Efficient Compressor
    • Low Frequency Operation
    • Speed Control System
    • High Efficiency
    • Stable Pressure

    Performance advantages of DAV II 2-Stage PM VSD Energy Efficient Compressor:

    • Low Frequency Operation

      Ultra-low temperature rise design, which allows the compressor running at ultra-low frequency for a long time.

    • Speed Control System

      Closed-loop vector control system for faster control and more precise speed control.

    • High Efficiency

      The compressor unit can still operate efficiently when the frequency is reduced by more than 50%.

    • Stable Pressure

      The pressure is stable and the pressure fiuctuation is accurately controlled within 0.1 bar.

    MAIN STRUCTURE
    • Control Module

      Control Module

      · RS485 communication mode transmission control signal
      · Intelligent PID flow adjustment mode
      · Closed-loop control, with ideal dynamic characteristics and control accuracy
      · Accurately control the torque
      · Fast response speed
      · Constant pressure control to avoid excess energy loss

    • Air End

      Air End

      · The rotor adopts the world's leading high-efficiency profile and is made of 1141 special steel, which has good hardness and high wear resistance.
      · Two-stage independent compression, low-speed design, lower overall noise.
      · The low compression ratio at each stage ensures smaller leakage and higher volumetric efficiency.
      · Oil mist spray cooling is used between stages, and the compression process is close to isothermal compression to improve efficiency.
      · The rotor and bearings are under little stress, and the long life of screw element is guaranteed to continue running.
      · Under the set frequency conversion pressure, the unit will automatically adjust to keep the output pressure within ±0.1 bar, reducing unnecessary waste (the power consumption increases by 7% for every 1 bar of pressure increase)

    • Permanent Magnet Motors

      Permanent Magnet Motors

      · High efficiency: Eliminates excitation system losses and improves efficiency.
      · It is still efficient under low load conditions: the energy efficiency of a permanent magnet motor is more than 9% higher than that of a conventional asynchronous motor at full load operation, and its energy efficiency remains unchanged as the speed decreases.
      · Large overdrive torque: The ratio of the maximum starting torque of the permanent magnet synchronous motor to the rated torque can be more than 3 times, while the general asynchronous motor is only 1.6 times.
      · The control is more stable: the corresponding time of the permanent magnet motor is <50ms, and the gas production can be adjusted in a large range in an instant, so that the gas pressure is truly stable.

    • Inverter

      Inverter

      · High utilization rate, removable panel, switch using, memory function
      · Protection: can realize phase loss, phase-to-phase short circuit, short-circuit to ground, over-current, over-voltage, under-voltage, overload, over-heat, motor thermal protection circuit board, reinforced coating, dust and corrosion protection
      · Independent cooling design, suspended installation, dust proof, corrosion proof, small heat, powerful overload and unique current limiting technology
      · Proprietary and efficient control procedures
      · Ultra-wide frequency design, wider control range
