Two-stage low-pressure PM VSD screw air compressors of the LDM series include the following models: DHH22LDM, DHH30LDM, DHH37LDM, DHH45LDM, DHH55LDM, DHH75LDM, DHH90LDM, DHH110LDM, DHH132LDM, DHH160LDM, DHH185LDM, DHH220LDM, DHH250LDM, DHH250LDMW, DHH280LDMW. Features: ✅ Air supply range from 5 to 70 m3/min. ✅ Power from 22 to 280 kW. ✅ Working pressure from 0.45 to 0.55 MPa. ✅ Two-stage compression unit without gearbox prevents loss of traction connection and mechanical damage. ✅ The compressor unit is driven by two separate permanent magnet motors and has intelligent control to ensure the highest compressor operating efficiency. ✅ The single-shaft drive mechanism for the compressor unit and motor prevents loss of traction connection and mechanical damage. ✅ The oil-immersed motor with IP65 protection with increased efficiency, which can be adapted to adverse and dusty working conditions. ✅ Unique optimized system with excellent input specific power. ✅ Energy-saving principles: The oil-injected screw air compressor uses two-stage compression to improve the energy efficiency of the compressor. After the first stage of compression, the oil and gas can be fully mixed between the stages, lowering the suction temperature of the two-stage compression, thereby reducing energy consumption.
