Advantages of The Air Compressor With Refrigerated Dryer
Ce 20 hp air compressor with dryer is easy to operate and maintain. Outre, it’s energy-saving and has low noise.
(1) Reliable Industrial Compressor Airend
The Hanbell airend adopts an advanced profile curve. Internal leakage loss is small. It has a good addendum speed. The profile of the airend is made by grinding, so the precision of the screw is higher. Our compressor airend is 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. It can 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 dans 1 Echangeur de chaleur à plaques. It has high heat exchange efficiency and more energy saving. Outre, it’s with an 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. The ultra-fine filter removes oil and solids. Filtration accuracy is 0.01 micron. Dans des circonstances normales, the exhaust oil content is ≤ 3 ppm. So meet the drying and filtering requirements of high-flow high-pressure air cutting.
Why Need 20 hp Air Compressor Dryer For Laser Cutting
Généralement, the screw air compressor, tank, and dryer are independent of each other. But it is very inconvenient during use. De plus, the cutting power of fiber laser cutters is increasing day by day. The cutting sheet thickness is constantly increasing. Cutting air pressures are also increasing. Ainsi, the 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. Enfin, brings damage to the protective lens. This problem needs to be solved. Donc, our air compressor with refrigerated dryer came into being.
The working principle of a 20 hp screw air compressor with dryer is as follows:
Rotary air compressor forms high-temperature and high-pressure air. Then refrigerated dryer reduces their temperature. En même temps, it can filter moisture, huile, and solid particles preliminarily. Après, the air is sent to the storage tank. The tank has the function of maintaining and stabilizing the pressure. De plus, it can further filter the moisture and precipitate solid particles. Enfin, the coalescing filters purify the air. Ensure that the air is dry and pure. It can also protect the laser-focusing lens.
FAQ
Q1: Can I add the automatic drain onto the filters and tank?
A1: Bien sûr. If you need to, we can add the auto drain. So it doesn’t need you to drain the water manually every day. This can better ensure the water removal effect of the air compressor with refrigerated dryer.
Q2: What kind of refrigerant do 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 jours. 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 the compressed air quality class supplied by your air compressor?
A4: Premièrement, this 15kw 20 hp screw air compressor is with refrigerated dryer. The pressure dew point is 3~10℃. Deuxièmement, the air compressor has multi-stage filters. The air oil content is less than 3 ppm. So it can meet the requirements for laser cutting.
