2023 Hot Sale Variable Frequency Screw Air Compressor with ABB Converter

Variable Speed Drive Rotary Screw Air Compressor AdvantagesDENAIR VSD (Variable Speed Drive) rotary screw air compressors are suitable for customers who need different amount of air supply and extremely accurate pressure. It can facilitate customers to optimize production process and improve productivity. The principle of VSD is to adjust the motor rotation speed automatically according to the actual air demand. The reduced system pressure decreases the total energy consumption of the whole system, which can reduce energy costs by 35% or more.  The VSD air compressor reduces the energy consumption through the following points:1. Removing the low efficiency transformation process from the full loading to unloading2. Avoiding the power during the unloading process3. Keeping the pipeline pressure drop under 0.1bar4. Reducing the average working pressure5. Lowering the system pressure to reduce the system leakage6. The soft starting method increases the current balance and avoids the current surge7. A flexible choice from 4 to 13bar which reduces the power consumption most.Technical Parameters Of Variable Speed Drive Screw Air CompressorModelMaxinmumworkingpressureCapacity(FAD)InstalledmotorpowerDriving mode& Cooling methodDimensions(mm)WeightNoise level**Air outlet pipe diameter50Hz60Hzbar(e)psigMin.Max.Min.Max.Min.Max.Min.Max.kwhpLWHkgdB(A)m3/mincfmm3/mincfmDVA-57.51090.430.8515300.440.8716315.57.5Belt Driven90066096020062G3/4"8.51230.410.8514290.420.8415305.57.5DVA-77.51090.521.0418370.511.0219367.51090066096022062G3/4"8.51230.490.9817340.5118357.51010.51520.450.8916320.450.8916327.510131890.360.7213250.370.7413267.510DVA-117.51090.881.7632620.881.763162111590066096028062G3/4"8.51230.871.7331610.851.73060111510.51520.691.3724480.681.3724481115131890.561.1220400.561.1220401115DVA-157.51091.272.5345891.212.4343861520Direct DrivenAirCooling1330840103032564G1-1/4"8.51231.242.4844881.192.384284152010.51521.022.0336721.172.3441831520131890.991.9835701.142.2740801520DVA-187.51091.53531061.823.636412818.5251330840103040064G1-1/4"8.51231.472.94521041.773.546312518.52510.51521.452.95110210192.37428418.525131891.012.0236711.172.34418318.525DVA-227.51091.853.7651311.853.76513122301330840103044066G1-1/4"8.51231.813.61641271.813.6164128223010.51521.773.54621251.763.52621242230131891.452.9511021.192.3842842230DVA-307.51092.625.24931852.214.4178156304016001000140067066G11/2"8.51232.575.14911812.154.3176152304010.51522.565.11901801.823.64641293040131891.723.43611211.773.54631253040DVA-377.51093.256.51152303.867.73136273375016001000140071066G11/2"8.51233.246.471142283.817.63135269375010.51523.166.321122233.26.391132263750131892.555.1901803.146.281112223750DVA-457.51093.837.651352703.947.88139278456016001000140086069G11/2"8.51233.87.61342683.857.7136272456010.51523.286.571162323.597.181272544560131893.26.391132263.176.341122244560DVA-557.51094.99.81733464.69.21623255575180012001400135069G2"8.51234.869.711713434.539.06160320557510.51524.629.241633263.97.81382755575131893.687.351302603.87.591342685575DVA-757.51096.9613.912464916.2712.5322144275100180012001400145069G2"8.51236.3312.662244475.8611.712074137510010.51524.769.511683365.1310.2618136275100131894.629.241633264.719.4216633375100DVA-907.51098.4516.92985978.4516.9129859790120245018001700210072DN808.51238.3516.72955908.416.82975939012010.51527.2514.52565127.3814.7626152190120131896.2512.52214415.7111.4220240390120DVA-1107.510910.420.836773410.0320.06354708110150245018001700250075DN808.512310203537069.9919.9835370611015010.51528.7517.53096188.416.8297593110150131897.2514.52565127.3314.67259518110150DVA-1327.510911.7523.541583012.2224.43431863132175245018001700260075DN808.512311.623.241081911.9223.8342184213217510.51529.9219.833507009.919.79349699132175131898.2316.462915818.3216.64294588132175DVA-1607.510914284949891427.99494988160215265017001760315075DN808.512313.52747795313.6627.3248296516021510.5152122442484712.0224.034248491602151318910203537069.8819.75349697160215DVA-185(W)7.510915.130.2533106615.2330.455381075185250DirectDrivenAirCoolingW-WaterCooling265017001760355075DN808.512315.0730.14532106415.0330.06531106118525010.515213.1226.2446392713.7727.544869721852501318911.5423.0840781511.8823.75419839185250DVA-200(W)7.510917.535618123615.5231.035481096200270300019502050420078DN1008.51231734600120115.1730.35536107120027010.51521530530105914.8529.69524104820027013189132645991813.4926.97476952200270DVA-220(W)7.510918.2536.5644128918.8437.686651331220300300019502050430078DN1008.51231836636127116.6233.24587117422030010.515215.8231.63558111716.5833.1658511712203001318914.2828.55504100813.4926.97476952220300DVA-250(W)7.510922.6545.3800160021.4942.997591518250350300019502050440078DN1008.512321.543759151821.0842.17744148925035010.515218.537653130616.7533.559111832503501318916.2532.5574114816.3732.745781156250350DVA-280(W)7.510923.2446.47820164123.5847.168331665280375370023002450490078DN1258.512322.7745.53804160822.8245.64806161228037510.515220.4540.89722144420.5441.0372414492803751
