25 hp screw air compressor structure  Why choose our 18.5kw industrial screw air compressor? (1) Reliable air compressor airend

We use the famous brand Hanbell airend. They produce the rotor with German processing equipment. Thus it ensures parts dimensional accuracy. Besides, Hanbell airend are larger than domestic airends of the same model. So more exhaust. The bearings adopt the world brand – SKF. Reliable quality, low failure rate. The warranty is 2 years.


Our airend uses the toothed double helix structure. The gear ratio of male and female rotors is 5:6. It makes full use of rotor inter-tooth volume. Besides, the streamlined design increases the flow area of the intake and exhaust ports. Large rotors are with low speed. So less noise.


(2) High quality permanent magnet motor

Our 25 hp industrial compressor uses 38UH permanent magnet motor. It’s a kind of high temperature resistant motor. It does not lose magnetism at 180°C. The service life is more than 15 years. Besides, it maintain extremely high motor efficiency at low speeds. When the air consumption is small, it has obvious energy-saving advantages. Because of one-piece structure, our 25 hp screw compressor is small in size. So it saves space and is easy to assemble and disassemble.


PM motor protection class is IP54. So it can adapt to the harsh working environment. In addition, the motor is directly connected to the male rotor of the airend through a coupling. Therefore the transmission efficiency is high. Wide speed range and high precision. The efficiency of permanent magnet motor is 3%-5% higher than that of ordinary motor.


vsd air compressor energy saving


(3) Excellent energy saving effect

This air compressor has a frequency inverter. Therefore, it can adjust motor speed in real time according to the actual air consumption. So as to achieve the purpose of controlling the exhaust air volume. When the air consumption is low, the machine will automatically sleep. Thus, it can greatly reduce the energy loss.


Energy bills can often far exceed the cost of the air compressor itself. Frequency conversion can avoid frequent loading and unloading under the change of air consumption. Therefore, variable speed drive air compressors can often save more than 30% of electricity bills. Moreover, stable pressure output can avoid high load current loss.


Constant pressure air supply: precisely control the air supply pressure within 0.01MPa. Constant temperature air supply: Generally, the constant temperature is set at about 85°C. This makes the lubricate oil work best. At the same time avoid high temperature stopping. Besides, it eliminate “No load”. Reduce 45% no-load energy consumption.


Additionally, it also eliminates excess pressure. For every 0.1MPa increase in air compressor pressure, energy consumption increases by 7%. Guarantee vector air supply and precise calculation. Finally, ensure that the air output of screw compressor is always consistent with the demand of the user system.


(4) The 25 hp rotary screw air compressor is with intelligent control

Easy to operate. The movement status of the air compressor is clear at a glance. And it’s with automatic alarm protection for faults, such as motor short circuit, phase loss and overload. Besides, it can automatically load and unload according to the air consumption. Automatically adjust the exhaust air volume. It can also realize multi-unit connection and remote control.


(5) High quality cooler

The 25 hp industrial compressor uses aluminum plate-fin cooler. The fin structure increases the secondary heat exchange area. Promotes turbulence and improves heat exchange coefficient. Compared with similar models, the heat exchange area is increased by 30%. Moreover, the margin is large. Even in hot and humid areas, it will not affect normal use.


(6) Low noise

The frequency inverter is a soft start device. Start-up shock is very small. There will be very low noise when starting up. At the same time, the operating frequency of VSD air compressor is lower than that of the power frequency air compressor. So it greatly reduces mechanical noise.


FAQ

Q1: What’s the warranty period of your 25 hp rotary screw air compressor?

A1: Our industrial rotary air compressor has reliable quality. The whole 18.5kw 25 hp screw compressor has one year warranty time. And the the key part airend has two years warranty time.


Q2: Can we customize our color and logo?

A2: Sure. We are industrial screw air compressor factory. If you want to paint your color, there is MOQ 10 sets requirement. If you only need print your logo on the 25 hp industrial compressor, there is no MOQ.


Q3: Do you also produce the screw air compressor with Baosi airend?

A3: Sure. The regular airend of our air compressor is Hanbell brand. If you need Baosi airend, we also customize it.


Q4: What’s inverter brand of your 25 hp screw compressor?

A4: Our regular inverter brand is famous Inovance. Moreover, the Inovance panel comes with multiple languages. So we can set different languages for the air compressor.
