55kw 75HP Energy Saving Air Cooling Screw Compressor Two Stage Direct Driven Screw Air Compressor

Product Description55kW 75hp Energy Saving Air Cooling Screw Compressor Two Stage  Direct Driven Screw Air CompressorProduct Description Permanent magnet variable frequency screw air compressor:1. Constant pressure control: It can realize high-precision constant pressure control with a pressure fluctuation range of 0.01 MPa;2. Variable frequency soft start: Eliminate the peak current when starting, avoid grid impact, avoid current impact through step-by-step speed adjustment, and improve flexibility3. Prevent no-load: The compressor is no-load during operation, reducing ineffective energy consumption;Permanent magnet motors use high-efficiency rare earth magnets, no loss of magnetism at 180°C, and long service life; energy saving is about 6% to 7% compared with ordinary frequency conversion motors;It can exert the highest efficiency in a wider range and make the air compressor more energy-saving.Two stage air endFeature:Two-stage compressor air-endAdvantage:Low compression ratio, Low temperature rising, Low air leakageBenefit:15% energy-savingHigh-efficiency MotorFeature:IE4 permanent magnet motor/IE4 High-efficiency motorAdvantage:Motor efficiency 97%Benefit:5% energy-savingIntelligent controlFeature:VFD systemAdvantage:Constant pressure output to remove pressure fluctuation and off-load, Constant temperature output at 9-~85°C, Low starting current to protect componentsBenefit:15% energy-savingSmart display screenFeature:Intelligent control systemAdvantage:10 inch monitor to show all the dateBenefit:Simple operation and touble freeCooling fanFeature:Large cooler systemAdvantage:Axial flow Fan used for good cooling effectBenefit:Allow ambient temperature at 52°CSystematic Design of Oil separatorFeature:Large oil systemAdvantage:Reduce internal pressure loss avoid oil, Leakage for safetyBenefit:3% energy-savingFilterFeature:Double filtering systemAdvantage:Remove impurity from air and cleannessBenefit:Longer life air -end and lubrication oilAir inlet valveFeature:High vacuum degree:700mmHgAdvantage:Large suction area, Low load energy consumption in unloaded operation, Fast check: prevent unloading and shutdown oil injectionBenefit:Cast aluminum to avoid rust and temperature change Technical Parameters ModelAir Delivery (m3/min)Power(kW)Noise(Db)OutletdiameterDimension (mm)Weight(Kg)0.7Mpa 0.8Mpa 1.0Mpa 1.3Mpa L * W * HRK30APMII4.34.13.52.72268G11/21500x1000x1350650RK40APMII65.94.73.93068G11/21500x1000x1350700RK50APMII7.16.95.85.43768G11/21500x1000x1350750RK60APMII109.57.86.84572G22100x1300x16501250RK75APMII1312.59.27.55576G22100x1300x16501300RK100APMII15.515.21210.27576G22100x1300x16501350RK125APMII19.819.515149076DN802500x1650x19002700RK150APMII242319.21611076DN802500x1650x19002800RK180APMII27.52723.71913278DN802500x1650x19003000RK220APMII3332.527.522.516078DN803000x1900x19504300RK250APMII39363227.518578DN803000x1900x19504400RK275APMII43.54135.531.520078DN1003600x2200x22005000RK300APMII51.548.338.535.522082DN1003600x2200x22005500RK350APMII5451453825082DN1003600x2200x22006000RK380APMII6057504328082DN1254000x2300x23006800RK420APMII65625650.531582DN1254000x2300x23007000RK480APMII7573645535582DN1504200x2200x23508500RK540APMII8482726140082DN1504200x2200x23509000Packaging & ShippingPackaging & Shipping1.Packing Details: Plywood crate pallet plus foam board and bubble film, Full closed wooden case. 1pcs/each package(for stationary screw air compressor)2.Shipping method: by sea, by LCL/FCL or as requested3.Delivery method: FOB, CFR, CIF and EXW etc.4.Delivery time: in 7-15 days after receiving deposit (customized machines not included)  Successful casesCompany ProfileShanghai Rocky Machinery Co., Ltd. was established in 2003 and has 18 years of experience in the air compressor industry.
