Technical advantages of our PM VSD industrial air compressor 50 hp
(1) Obvious energy-saving advantage
Take this 37KW power frequency screw air compressor as an example. The average air production only accounts for 70% of the rated air flow. The machine runs 8000 hours a year. The electricity fee is 0.7CNY/kWh. Compared with VSD air compressor, it will consume more electricity bills.
1) No-load power consumption: 30% unloading time * no-load current consumption (45%*37KW/hour)8000 hours/year*0.7CNY/kWh=28000CNY/year
2) Differential pressure power consumption: 70% loading time * differential pressure loss (14% * 37KW/hour) * 8000 hours/year * 0.7CNY/kwh = 20300CNY/year.
To sum up, the PM VSD 50 hp rotary screw compressor can save energy consumption of 28000+20300=48300 yuan/year. This can buy a new machine. It’s higher than 50 hp compressor price.
(2) Excellent screw airend
The compressor airend adopts a five-six-tooth ratio rotor. Compared with the ratio of four and six teeth, it reduces drop by 25%. Therefore, greatly improve the compression efficiency. The large rotor results in a small leakage area. Further improve compression efficiency. Besides, we use German processing equipment. Tooth shape precision is high. Under continuous operation, the rotor can maintain the optimum clearance value. So airend is stable and efficient. Moreover, the bearing is the Swedish SKF brand. Thus, the airend is more durable.
(3) High-efficiency permanent magnet variable frequency motor
Firstly, the PM compressor motor remains efficient at low loads. At full load, it is at least 9% more efficient than asynchronous motors. Besides, as the speed is reduced, the energy efficiency remains the same.
Secondly, it has a large starting torque. The ratio of the maximum dynamic torque to the rated torque can be more than 3 times. The general asynchronous motor is only 1.6 times.
Thirdly, the control is more stable. The response time of the permanent magnet motor is less than 50ms. Air production can be adjustable in a wide range in an instant.
Fourthly, high temperature resistant rare earth RuFeB magnets are used. Therefore, the stability of the 50 hp screw compressor is better.
(4) Reliable quality spare parts
The air compressor air filter adopts multi-stage sealing. It’s flexible and stable. And oil filter can withstand high temperature of 120°C. The classification efficiency can reach 99%. Compressed air oil content ≤ 3ppm.
The intake valve has a high vacuum. In addition, cooling fan has low noise and high air volume.
Q1: This 50 hp rotary screw air compressor is variable speed or fixed speed type?
A1: This industrial air compressor 50 hp is PM VSD type. There is inverter inside. Although this VSD 50 hp compressor price is more expensive, but it is energy efficient.
Q2: Do I also need the compressed air dryer for the 37KW screw compressor?
A2: This bases on the specific industrial application. In fact, many industries have requirements for dew point. And they require at least one refrigerated air dryer. Its dew point can reach 3~10℃. Of course, some other industries have lower dew point requirement. At this time, you should also buy a regenerative desiccant dryer.
Q3: What’s the 50 hp screw compressor price?
A3: Pls tell us the voltage you need. Our regular voltage is 380V 50HZ 3-phase. If you need 220V / 240V/ 415V / 440V or 60HZ, then the price will be a bit higher.
Q4: If I customize the color, what’s your MOQ?
A5: For the 50 hp rotary screw air compressor, the color customization MOQ is at least 5 sets.
