UDL series oil-free screw compressor
The high-performance host adopts stainless steel rotors with special coatings, unique rotor clearance control technology, and highly reliable sealing
Product details
  • The high-performance host adopts stainless steel rotors with special coatings, unique rotor clearance control technology, and highly reliable sealing technology.

  • The energy-saving technology of permanent magnet frequency conversion and the pressure prediction control function of IPC terminal effectively reduce power consumption.

  • Diversified design with complete control functions and easy-to-use LCD display screen.

  • The highly reliable environmental protection technology OMCS ensures the recycling and reuse of gearbox oil fumes without polluting the environment.

  • The low-noise cable host and vibration insulation structure ensure low noise operation of the entire machine.

  • IT communication function, data can be recorded in USD and communicated via Bluetooth network server function and Modbus.

  • Advanced multi control panel system (MULTI ROLLER EX).

  • environment protection

    -Dry oil-free (Class 0 clean oil-free compressed air).

    -All of our zero grade oil-free air compressors comply with the food safety management system.

    -The advanced technology oil mist recovery device (OMR) has an efficiency of 99.99% and is more environmentally friendly.

  • low noise

    -Low noise, sophisticated model.

  • Energy saving:

    -55. 75KW air-cooled variable frequency turbo fan, energy-saving and low-noise.

    -55 and 75KW permanent magnet frequency converter models are more energy-efficient.

    -IPC control (advanced terminal pressure predictive control).

  • High performance rotor

    -Stainless steel rotor has stronger corrosion resistance and durability.

    -Unique 3D correction technology ensures consistent rotor clearance during high-temperature operation.

  • maintenance

    -6-year host warranty period, low operation and maintenance costs.

    -Low oil consumption and easy maintenance.

  • cooling system

    -Water cooler: Air flows through the tube side, water flows through the shell side, with high heat transfer efficiency.

    -Air cooled model: equipped with a coil pre cooler.
