Advantages of two-stage screw compression host:

※The working temperature is lower than that of single-stage compression, and it tends to be more power-saving isothermal compression, theoretically saving 8% energy.

※The compression ratio of each stage is lower, internal leakage is reduced, and the volumetric efficiency is increased by 5 to 10%.

※It is conducive to adjusting the rotor of each stage to achieve the optimal line speed range of 25~35m/s, and obtain the highest compression transmission efficiency

Product features of permanent magnet variable frequency two-stage compression screw air compressor:
1. A two-stage compression screw air compressor with the same power can produce 13%-15% more gas than an ordinary single-stage compression screw air compressor.
2. Adopt internationally advanced frequency conversion technology to achieve stepless speed regulation, constant pressure air supply and soft start, completely eliminating wasted work losses and intelligent air supply.
3. It adopts continuous shaft transmission and IP54 protected motor, which is safer, more efficient and more energy-saving.
4. Adopt a special frequency converter for permanent magnet synchronous motor to achieve stepless speed regulation, constant pressure air supply and soft start, completely eliminating the loss of wasted work and intelligent air supply.
5. Fully intelligent control, dynamic display of system working conditions, real-time monitoring of important parameters, intelligent automatic power on and off, fully achieving continuous operation without supervision.

★Intelligent LED liquid crystal display control system: Microcomputer intelligent monitoring system, fully automated Chinese and English display, touch buttons, easy to operate.

★Intelligent 360-degree all-round safety protection device saves you worry, effort and money

1. Excessive exhaust temperature protection 2. Exhaust pressure excessive protection 3. Power supply error protection (phase loss, reverse phase protection)

4. High current protection 5. Electrical failure protection 6. Motor overload protection 7. Fan motor failure protection 8. Oil pressure abnormality protection 9. Oil shortage protection

★Maintenance reminder function:

1. Air filter: digital pressure difference indication & warning reminder when usage time reaches set value

2. Oil filter: Digital pressure difference indication & warning reminder when usage time reaches set value

3. Oil and gas separator: digital pressure difference indication & warning reminder when the usage time reaches the set value

★Multi-machine chain remote monitoring system

In the office, you can monitor the operating status of the compressor from your computer at the same time, making it easier to manage the machine and saving energy.

Using the network, you can expand the monitoring scope and improve the maintenance operation time, total load time, exhaust pressure, exhaust temperature, operating current, fault details, etc. at a glance.
