    Low Noise Industrial Screw Compressor With Constant Pressure Control


    Leading constant pressure control


    AVF permanent magnet variable frequency screw compressors can sustain the air supply at the pressure of 0.1 bar in any loading conditions. In case of larger demands for air supply, the compressor can increase its rotation speed without changing the pressure to guarantee the air volume. In case of lower demands for air supply, the compressor can reduce its rotation speed without changing the pressure to meet such demands. In case of no demands for air supply, the compressor will switch to sleep mode to save energy. When actual pressure achieves the wakening standard, the compressor will immediately start up with rapid response of frequency converters even in sleep mode.


    High-performance vector frequency converter

    • Standard equipment with radio-frequency reactor which effectively reduces magnetic field interference outside high-frequency machine generated by frequency converter;
    • Reliably reduces peak current when it is started, realizes stable starting;
    • Saves cost of electrical power units;equipped with standard dust screen, circuit board is processed with surface coating, so antifouling, anti-dust and damp-proof effects are realized;
    • equipped with standard dust screen, circuit board is processed with surface coating, so antifouling, anti-dust and damp-proof effects are realized;
    • Special heat dissipation design prevents tripping under summer high temperature;
    • Standard protocol of CAN with wire road standard of hardware and strong noise resistance;
    • Rapidly track change of pressure, control pressure fluctuation within ±0.01Mpa, optimal power is used to accurately provide necessary air amount;
    • Advanced integrated draught fan, and motor uses double-vector variable-frequency control technology.

    Reduce energy costs


    • When the energy accounts for above 70% of the life cycle cost (LCC) of compressor, the energy consumption optimization becomes essential. In fact, the power consumption for the production of compressed air accounts for over 40% of the total power consumption of the plant, so the energy consumption optimization can even determine its success. Using the permanent-magnetism frequency-conversion technology of Dresdnerlan, we can provide partners for your cost saving. WZS series of products can truly reflect the demand for compressed air, making substantial energy saving become a reality
    • Traditional compressors are operated between two set pressure points using the control methods of "full load and no load". The compressor turns into no load mode when the pressure reaches the maximum. When the air demand is medium or low, the no-load power will be consumed excessively, which will result in large amount of waste.
    • Because no unnecessary power consumption will be generated, the energy cost reduced by the permanent-magnetism frequency-conversion can be up to 35% or more. The life cycle cost (LCC) of the compressor can be reduced by an average of 22%. In a word, compared with the compressor with invariable rotate speed, Wan Beardsley compressor can recover the extra cost within 1 or 2 years.

    Energy Saving


    • Traditional compressors (standard machine) usually use ON / OFF or proportional regulation system, which adjusts the opening amount of the air inlet of compressor. The adjustment method can also meet the actual requirements of the actual gas consumption, but the revolving speed of the compressor maintains at the rated speed in the entire adjustment process, the frictional work and cooling fluid agitation work will not be reduced, so although the gas consumption is lowered, the actual power consumption is not limited substantially. The variable frequency regulation can make the actual power consumption of the variable frequency compressor decline in the same proportion, and the energy is effectively used into the air compression.
    • In the market environment with fierce competition, it is an important matter as to whether the cost can be reduced. With the use of PM frequency conversion technology, you can save energy, thereby decreasing electricity expenditure sharply. It adjusts the compressor production capacity automatically according

    Steady Pressure


    It tracks system gas volume changes automatically, and adjusts the revolving speed of compressor accurately with the use of PID (proportional, differential, integral), to keep the system pressure stable.


    Start without stamping


    • The variable frequency starting method reduces the impact of the start of the compressor on the power grid and mechanical parts greatly, thus extending the life of the machine.
    • Eliminate invalid transitional period from full-load power to no-load power
    • Avoid excessive no-load power consumption
    • Maintain the net pressure section
    • Reduce the overall average operating pressure
    • System pressure is low, making the system leak declined to a minimum
    • It accelerates with the use of soft-start motor gradually, to improve flexibility, thus avoiding the surge

    Similarly, for two models with above rated power 37kw, when load rate is only 605, input power of power-frequency model under ordinary air inflow throttling control is 39.2kw; while shaft power of permanent magnetic power-frequency motor is 23.6kw with electricity saving ratio being 37.5%. If we calculate according to 40,000 operating hours per year, annual electric charge of ordinary asynchronous power-frequency model is RMB 107,200, however, annual electric charge of permanent magnetic synchronous servo model is RMB 65,800, saving RMB 41,400 in each year.
