A. The Picture for GREAT PM VSD 2-Stage Compression Screw Air Compressor:

B. Products Introductions&Advantages for 15-250kw oil injected PM VSD 2-Stage Compression Rotary Screw Air Compressor:
Air End:
1. The two-stage air end has two independent compression units, using integrated design.
2. The air end is adopted the design concept of large rotor with low speed, the spindle speed is around 1500, low noise, low vibration.
3. The oil circuit design is optimized, forced atomized oil cooling is adopted between stages, so the air end is closer to isothermal compression.
4. The air end used the design of constant pressure ratio, less leakage, improve volume efficiency.
5. Reasonable wall thickness design, optimize the design cost.

Motor: 
1. Oil cooling high efficiency permanent magnet motor. Insulation grade F, protection grade IP54,adapt to the high dusty environment.  IE4 Efficiency motor efficiency.
2. Low noise, high efficiency, better life-span. Split design, Easy for installation and service
3. Without gearbox design, motor is connected directly with rotor through the coupling, high transmission efficiency. 
4. Independent cooling fan design, so that the motor cooling is not affected by the speed regulation.
5. Premium Magnetic material resist more than 180ºC temp.
6. Fantastic Energy Saving, save up to more than 30-40%.
 
Inverter : 
1. Dual variable frequency system: permanent magnet motor variable frequency + cooling fan motor variable frequency , one-piece integrated structure, extreme energy saving. 
2. Constant pressure air supply: the supply pressure is precisely controlled under 0.01 MPa. 
3. Constant temperature air supply: constant temperature set at 85 ºC, with the best lubrication 
4. Eliminates empty load, reduces the empty load energy consumption by 45%. 
5. Large Frequency range 30%~ 100% 
6. Vector air supply, accurate calculation, ensure that the air flow of Compressor is consistent with the demand of the user system. 
 
Intelligent control system : 
1. Direct display: discharge temperature, discharge pressure, operating frequency, current, power, running state, etc. 
2. Real-time monitoring of discharge temperature, discharge pressure, current, frequency fluctuation. 
3. Optional the Internet of things module, external cloud intelligent management system, realize the functions such as remote start-stop and remote online monitorin.

D. Product Feature:
The normal oil injected screw air compressor can achieve the usual power system exhaust pressure by only Single stage compression.  But from the view of energy consumption point, the use of 2-stage of compression can effectively reduce energy consumption. 

So, Tianjin Great air compressor co., LTD. has introduced 2-stage compression of energy efficiency screw air compressor.  The 2-stage compressed-jet screw air compressor has more capacity of 12% to 18% than the single stage compressed injection screw  air compressor with the equivalent power.  In other words, with the same amount of compressed air, the 2-stage compression can save an average of 15% of power compared with single stage compression.

The 2-stage compression of oil injected screw machine has the unique design of the air end, it will combined the single stage compression rotor and 2-stage compression rotor within a chassis, make each rotor can get optimal linear velocity by the gear directly rotating respectively, so the compression efficiency is higher. 

The 2-stage compression air compressor, take the built-in spray curtain of cooling, cooling effect is good, greatly reduces the temperature of compressed air, realize the nearly isothermal compression, and can reduce the pressure loss of between 1 class ~ 2 class, lower compression ratio and improve the compression efficiency.
