Lingyu - 50m³/min 3Bar Low Pressure Refrigerated Air Dryer
Lingyu is top manufacturer of low pressure refrigerated air dryer. Normally refrigerant dryer is 7~10bar. But this low pressure air dryer is 3bar. Besides, this one is high temperature refrigeration dryer. In addition to the 3bar dryer, we can also customize other low pressure dryers, such as 4bar, 6bar, etc. It can remove moisture in compressed air effectively. Finally we can get the low pressure dew point. The low pressure air dryer applications are as follows: textile, printing, ceramic industry, etc.
Why choose our commercial air compressor dryer?
Reliable explosion-proof performance
We design the air dryer refrigeration system according to explosion-proof requirements. Moreover, it reaches the explosion-proof grade EXD?BT4. Control box and fan have explosion-proof certificate. In addition, the refrigerant compressor is also explosion-proof. And we provide factory explosion proof treatment certificate.
High-quality refrigerant compressor
This commercial air compressor dryer adopts the USA Copeland refrigerant compressor. This is a world famous brand. High cooling efficiency and stable performance. So our refrigerant air dryer runs stably. It can guarantee good water removal performance.
Excellent control system
Fully automatic adjustment and control. So it’s stable and reliable. Besides, it’s easier to control. Additionally, we provide a variety of customization. PLC and RS485/RS232 communication is available. This enables remote control.
High-quality refrigeration components
Our refrigerated air dryer has a hot gas bypass valve and filter dryer. It’s also with high and low voltage protection. So it ensures that the air dryer refrigeration system is stable.
How to choose low pressure refrigerated air dryer for air compressor?
In fact, for low pressure dryers, there is a quick selection formula:
Dryer air flow=air compressor air flow * 8bar/(working pressure +1bar)
This formula applies to dryers, filters, coolers, etc. The pressure range is 3.5bar to 6bar. Volume is inversely proportional to pressure. So the lower the pressure, the higher the dryer flow.
Assume that the air compressor capacity is 13.5Nm3/min. Its exhaust pressure is 0.45MPa. The discharge temperature is 40°C. In addition, need the pressure dew point of 2 to 10°C. Then, the air flow of refrigerant dryer = 13.5*8/5.5=19.6 Nm3/min. Therefore, choose a 150P air dryer.
If dryer selection is too small, the pressure drop will be too large. It will also cause problems such as substandard export dew point. In addition, if there are strict requirements for pressure drop, it requires special design.
