They are fully aware of the fact that CROWNWELL AIR is more than just ordinary compressed air: utmost safety, outstanding efficiency, excellent quality, maximized flexibility along with dependable service are the ingredients to transform CROWNWELL AIR into air to work with - in China, in Asia and in more than 102 countries around the world.The III generation, the basis for economical compressed air productionThe Know-HowMore than decades of know-how in manufacturing for the compressed air market. World wide knowledge in different compressed air applications have guided the development of customer specified stationary screw compressors. Technical Advancement for your BenefitThe advantage of CROWNWELL lies in its simplified construction. Fewer components are utilized. This means a 60% reduction in main and wearing parts and over 70% fewer pipes and connections. In turn, this greatly reduces the risk of leakages, making the system environmentally friendly. Safe direct drive operation without V-belt transmission. The CROWNWELL Screw Compressor works in the following way:Ambient air is drawn through the intake filter and the multifunctional control system into the screw compressor block. This block consists of a pair of screw rotors. The main rotor, driven by an electric motor, takes the secondary rotor with it. The air is drawn in by the rotation of both of the interlocking rotors and is continually compressed. During rotation, coolant is injected into the rotors and forms a hydrostatic film between the main and secondary rotors. The function of the coolant is to seal the rotors, lubricate the bearings and adsorb the compression heat. Before compressed air leaves the compressor ( at 80 ºC approx.) it is separated from the coolant before being cooled in the aftercooler to approx.. 8ºC to 12ºC above the ambient temperature. The coolant then passes to the thermostatic control block and filter, before entering the cooler where it is cooled from approx.. 80ºC down to 50ºC. It is then injected back into the screw compressor block.Features: Direct drive via flexible coupling.Fully encapsulated CROWNWELL screw compressor block.Standard electric motor Protection Index IP23 and IP54.User friendly service access.Top quality, washable, oil resistant sound insulation.Ready for operation, prewired and fully enclosed.With operating mode selector switch Automatic-Off-Continuous.Centrally mounted cooling fan provided for compressed air and lubricant coolers.Compact and neat cabinet design.Optional Equipment:Sense of rotationMultiple unit control with automatic base load selectionFull motor protectionMains isolator switch for wall mounting Beyond these features we offer a wide choice of compressed air accessories in reference to our compressor product range.Energy Recovery Systems CROWNWELL-THERMCompressed Air FiltersCompressed Air DryersCondensate TrapsOil-Water SeparatorsCompressed Air ReceiversCrownwell OIL-INJECTED PERMANENT MAGNET Variable Speed COMPRESSORTECHNICAL SPECIFICATIONS CWD 7-400 PM(7.5-400kW / 10-500hp)ModelMotor PowerkW / hpFree Air Deliverym3/minNoise LeveldB(A)DimensionL * W * HmmWeightKg7barg8barg10barg13bargCWD7 PM7.5 / 101.31.21.00.866760*700*920200CWD11 PM11 / 151.71.61.41.268980*750*1000350CWD15 PM15 / 202.52.32.11.968980*750*1000360CWD18 PM18.5 / 253.23.02.72.4681120*850*1160500CWD22 PM22 / 303.83.63.22.8681120*850*1160520CWD30 PM30 / 405.35.04.54.0681120*850*1160550CWD37 PM37 / 506.86.25.65.0681280*1000*1290750CWD45 PM45 / 608.07.37.05.9721280*1000*1290780CWD55 PM55 / 7510.19.58.77.8721800*1230*15701600CWD75 PM75 / 10013.612.812.310.2721800*1230*15701800CWD90 PM90 / 12516.215.514.012.5721800*1230*15701900CWD110 PM110 / 15021.219.817.815.5722400*1470*18402500CWD132 PM132 / 18024.523.220.517.8752400*1470*18402700CWD160 PM160 / 21528.827.825.022.4752400*1470*18403000CWD185 PM185 / 25032.531.228.025.8753150*1980*21503500CWD200 PM200 / 27036.034.330.528.0823150*1980*21504000CWD250 PM250 / 35043.041.538.234.9823150*1980*21504500CWD315 PM315 / 40051.050.244.539.5823150*1980*21506000CWD355 PM355 / 45064.061.056.549.0843150*1980*21506500CWD400 PM400 / 50071.268.162.852.2843150*1980*21507200Unit performance measured according to ISO 1217, Annex C, Edition 4 (2009)Reference conditions: -Relative humidity 0%-Absolute inlet pressure: 1 bar (a) (14.5 psi)-Intake air temperature: 20°C, 68°FNoise level measured according to ISO 2151:2004, operation at max. operating pressure and max. speed; tolerance: ±3 dB(A)PM-Permanent MagnetCrownwell TWO-STAGE OIL-INJECTEDPERMANENT MAGNET Variable Speed COMPRESSORTECHNICAL SPECIFICATIONS CWD 7-400 PM(7.5-400kW / 10-500hp)ModelMotor PowerkW / hpFree Air Deliverym3/minNoise LeveldB(A)DimensionL * W * HmmWeightKg7barg8barg10barg13bargCWD15II-PM15 / 203.02.92.42.2681480*850*1180780CWD18II-PM18.5 / 253.63.52.92.5681480*850*1180800CWD22II-PM22 / 304.24.13.53.2681480*850*1180820CWD30II-PM30 / 406.56.44.94.2681720*1110*14801080CWD37II-PM37 / 507.27.16.35.4681720*1110*14801100CWD45II-PM45 / 609.89.77.86.5721720*1110*14801120CWD55II-PM55 / 7512.812.59.68.6722100*1350*17202080CWD75II-PM75 / 10017.516.512.511.2722100*1350*17202100CWD90II-PM90 / 12520.819.816.914.3722460*1700*19003280CWD110II-PM110 / 15024.523.519.717.6722460*1700*19003480CWD132II-PM132 / 18030.028.023.519.8752900*1800*20203980CWD160II-PM160 / 21534.533.630.023.8752900*1800*20204280CWD185II-PM185 / 25041.038.432.528.6753800*1980*21505450CWD200II-PM200 / 27044.643.038.532.8823800*1980*21505600CWD220II-PM220 / 30048.647.041.038.0823800*1980*21506500CWD250II-PM250 / 35055.054.046.040.0823800*1980*21506600Unit performance measured according to ISO 1217, Annex C, Edition 4 (2009)Reference conditions: -Relative humidity 0%-Absolute inlet pressure: 1 bar (a) (14.5 psi)-Intake air temperature: 20°C, 68°FNoise level measured according to ISO 2151:2004, operation at max. operating pressure and max. speed; tolerance: ±3 dB(A)II-Two Stage, PM-Permanent Magnet
