Technical data of air compressor dryer for sale

Why buy our refrigerated air dryer for sale?

(1) The outstanding feature of our refrigerant dryer is stability. Moreover, the water removal performance is excellent. The pressure dew point is 2~10℃. In addition, we can achieve a minimum of 3~5 ℃.

(2) It uses famous brand refrigerant compressor. That is, Panasonic compressor. So our air compressor dryer for sale has excellent cooling effect. And it’s stable and durable. In addition, Panasonic compressor has other advantages. For example, low noise and power saving. With built-in safety protection, it can work stably for a long time.

(3) This 130cfm air dryer is high inlet temperature type. This is because there are pre-cooler and heat exchanger. Compressed air will initially cool down. This reduces the load on the compressor. Therefore, our refrigerated air dryer for air compressor can better adapt to the harsh working environment.

(4) This 130 cfm air dryer uses 2 external rotor cooling fans. There is a lot of wind. Besides, the lifetime is long. Therefore, the heat dissipation efficiency is high.

(5) It adopts wide flow channel and large capacity design. So the air pressure loss is lower. It’s no more than 0.02MPa. So the energy consumption of air compressor dryer system is small.

(6) The dryer is with a cyclone water separation mechanism. At the same time, there is original Netherlands Jorc brand electronic drain. Therefore, the water separation efficiency is greater than 99%.

(7) Air compressor dryer for sale is with multiple protection devices. Such as overheating, overcurrent and high and low voltage protection. So compressed air dryer system runs safely and stably.

(8) The heat exchange system uses high-quality raw materials. For example, the copper tube is 0.5mm red copper. The fins are hydrophilic aluminum foil. Therefore, the heat exchange efficiency is high.

(9) Our refrigerated air dryer for air compressor often cooperate with big brands. Such as often Hitachi, Sullair, Atlas, Ingersoll Rand and so on.

How does refrigerant air dryer works?

The refrigerant has a low boiling point characteristic. It will change from liquid to gas during heat exchange. So it can absorb the temperature of the compressed air. Finally, it will reduce its temperature. At the same time, the moisture will condense into water.

The air compressor dryer for sale consists of three parts. Namely heat exchange system, refrigeration system and electrical control system. The screw compressor discharges moist air. There contains a lot of water and oil. Firstly, the compressed air passes the pre-cooler. Air-to-air heat exchange takes place here. That is, it takes the initial cooling.

Then they enter the air-to-refrigerant heat exchanger. Start to cool down further. Afterwards, enter the evaporator of refrigerated air dryer for air compressor. Air exchanges heat with refrigerant. It will realize deep cooling. That is, further reduce the temperature of the compressed air. And the pressure dew point will be 0°C~10°C. At this time, moisture, oil and impurities will condense out. The Jorc electric drain valve discharges them out.

So we get the dry and low-temperature air. Then they will go back to the air-to-air exchanger. Perform heat exchange again. Finally output when the temperature rises. Therefore, it can avoid condensation in the pipeline. This is a safety guarantee for the back-end air equipments.

Operating procedures of refrigerated air dryer for air compressor 1. Start-up process of air compressor dryer for sale

① Firstly, turn on the power. Observe the meter of refrigerated air dryer for sale. At this time, the power indicator (red color) is on.

② Secondly, press the green start button. The refrigerant compressor will start running. The operation indicator (green color) lights up.

③ Thirdly, check whether the compressor is running normally. Whether the pointer of the refrigerant low pressure gauge drops to the normal range. That is, 0.3~0.5MPa (R22 refrigerant).

④ If everything is normal, open the stop valve again. Supply air to refrigerated air dryer for air compressor. And close the air bypass valve.

⑤ Observe for 5-10 minutes. The refrigerant dryer can reach the pressure dew point of 2-10 ℃.

⑥ Finally, slowly open the ball valve on the auto drain. Let the condensate run into the drainer. They will be discharged out of the dryer through it.

2. Refrigeration dryer shutdown process

① Open the bypass. Let the compressed air continue to flow into the downstream piping. Then close the outlet valve of refrigerated air dryer for air compressor;

② Close the inlet shut-off valve. And depressurize the air compressor dryer for sale;

③ Finally, press the red stop button. Turn off the refrigerated air dryer for sale. Afterwards, cut off the power. Open the manual drain valve. Drain any residual condensate.

FAQ

Q1: Does the refirgerated air dryer also have high temperature failure?

Yes. In summer, the refrigerated air dryer for air compressor is easy to stop due to high temperature.

There are often two types of air compressor dryer for sale. That is, normal temperature (Max 45℃) and high temperature type (Max 80℃). If your refrigerant dryer is the former, it is prone to downtime. Because the high temperature will increase the workload of the refrigerant compressor. Long time high-load operation will cause downtime. So when selecting models, we must fully consider the influence of ambient temperature.

However, there is rarely the case with our refrigerated dryer. Because it is a high temperature type.

Q2: Why do you still need compressed air filters when you have a refrigerant dryer?

In fact, they have different functions. The main function of air compressor dryer for sale is water-removal. That is, to get the pressure dew point we want. Of course, it can also remove part of oil and impurities. But there are still much oil and impurities in the compressed air.

So we must need the compressed air filters. Their main functions are dust-removal and oil-removal. Besides, the filtration precision of our filters can reach 0.01 micron. And it can remove 99.99+% oil vapors.

Q3: Can use refrigerated air dryer for air compressor in winter?

It can use the refrigerant dryer in winter. But the refrigerant cannot cool down infinitely. Therefore, the air dryer can only cool down to about 3 °C at most. In winter, the temperature is lower. At some places, the temperature can reach below 0℃. At this time, ice blockage is easy to occur.

Therefore, it is recommended to use desiccant dryer, not air compressor dryer for sale. Its drying effect is good. And no ice jams will occur.
