The advantages of our air compressor with refrigerated dryer
This 20 hp air compressor with dryer is easy to operate and maintain. Besides, it’s energy-saving and has low noise.
(1) Reliable industrial compressor airend
The Hanbell airend adopts advanced profile curve. Internal leakage loss is small. It has a good addendum speed. The profile of airend is made by grinding. So the precision of the screw is higher. Our compressor airend are highly efficient. Better screw linear speed makes it more than 5% energy-saving than similar products on the market.
The lifetime of the airend rotor largely depends on the life of the bearings. We use the top quality bearings from SKF Company of Sweden. The service life is more than 20% longer than ordinary bearings.
(2) Top quality high temperature resistant PM motor
Our compressor motor adopts 180℃ high temperature permanent magnet material. Effectively ensure that the motor does not demagnetize. The quality is stable and reliable. So our 20 hp screw air compressor with dryer has long lasting life.
(3) High-quality energy-saving refrigerated dryer
The dryer uses a 3 in 1 plate heat exchanger. High heat exchange efficiency and more energy saving. Besides, it’s with a air-water separator. Its 99.9% separation efficiency ensures efficient water removal. The air compressor with refrigerated dryer can exhaust dry and clear air. The dew point can be up to 3~10℃.
(4) High-efficiency multi-stage filter device
20 hp air compressor with dryer uses the Italy ATS brand filters. The primary filter removes solids. Filtration accuracy is 5 microns. Ultra-fine filter removes oil and solids. Filtration accuracy is 0.01 micron. Under normal circumstances, the exhaust oil content is ≤3ppm. So meet the drying and filtering requirements of high-flow high-pressure air cutting.
Why need 20 hp air compressor with dryer for laser cutting
Usually the screw air compressor, tank, and dryer are independent of each other. But it is very inconvenient during use. Moreover, the cutting power of fiber laser cutter is increasing day by day. The cutting sheet thickness is constantly increasing. Cutting air pressures are also increasing. Thus, existing air filtration system can no longer meet the drying and filtration requirements. This leads to contamination of the focusing lens of the cutting head. Then the cutting effect becomes poor. Finally, bring damage to the protective lens. This problem needs to be solved. Therefore, our air compressor with refrigerated dryer came into being.
The working principle of 20 hp screw air compressor with dryer is as follows:
Rotary air compressor forms high temperature and high pressure air. Then refrigerated dryer reduce their temperature. At the same time, it can filter the moisture, oil and solid particles preliminarily. Afterwards, air is sent to the storage tank. The tank has the function of maintaining and stabilizing the pressure. Moreover, it can further filter the moisture and precipitate solid particles. Finally, the coalescing filters purify the air. Ensure that the air is dry and pure. And it can also protect the laser focusing lens.
Q1: Can I add the automatic drain onto the filters and tank?
A1: Sure. If you need, we can add the auto drain. So it doesn’t need to you to drain the water manual every day. This can better ensure the water removal effect of the air compressor with refrigerated dryer.
Q2: What kind of the refrigerant you use in the refrigerated dryer?
A2: It’s usually R22. But we also supply other refrigerant, such as R134a, R410a, etc.
Q3: What’s the production time of your 20 hp screw air compressor with dryer?
A4: If 380V/50HZ is suitable for you, the delivery time is about 15 days. And we also customize the different voltages, such as 220V, 415V, 440V, 460V and 60HZ, etc. Then the product time will be longer. It’s about 35~40 days.
Q4: What’s compressed air quality class supplied by your air compressor?
A4: Firstly, this 15kw 20 hp screw air compressor is with refrigerated dryer. The pressure dew point is 3~10℃. Secondly, the air compressor is with multi-stage filters. The air oil content is less than 3 ppm. So it can meet the requirements for laser cutting.
