Why Choose Our Water-cooled Refrigerant Air Dryer
(1) Use The Best Refrigerant Compressor
Firstly, this refrigerated air dryer uses two sets of Danfoss compressor. This is the best brand in the world. Danfoss compressors are not only powerful in cooling, but also stable in performance. It has safety guards inside. So it can minimize maintenance costs of our compressed air dryer for sale. Also avoid unplanned downtime.
In addition, it has the characteristics of low noise. So our air compressor air dryer system is quiet. It will reduce noise pollution to production workshop.
(2) Compressor Air Dryer System Uses Good Spare Parts
Firstly, the throttling device is the Danfoss expansion valve. It can automatically adjust the supply of refrigerant. So it can avoid “hydraulic compression” . Keep our compressors safe.
The hot gas bypass valve is American Sporland brand. It can prevent the evaporation temperature from being too low. So the condensation will not freeze. Thereby, avoid the ice blockage.
And air compressor air dryer system is with automatic regulating valve. It can adjust the flow of cooling water. So it will ensure stable outlet dew point. At the same time, it can effectively prevent the evaporator from freezing.
In addition, our electrical components use well-known brands. For example, the contactor of the refrigeration host is from Schneider, France. So is the thermal overload relay.
In conclusion, our compressed air dryer for sale has reliable performance.
(3) Compressor Dryer System Has Automatic Energy Saving Control
Lingyu develops the dual-system energy-saving control. It can automatically adjust according to the load 60%/100% capacity. Besides, it is a dual temperature digital display. Finally, it can achieve optimum operational energy efficiency.
The No. 2 refrigeration system only starts when the No. 1 is overloaded. Therefore, our compressor dryer system can save a lot of energy. Especially sometimes the air consumption is small. Or ambient temperature is low in winter. At this time, it can reflect the significant energy saving efficiency. Compared with the traditional control method, it can save more than 20% energy.
(4) Excellent Drainage System in Compressed Air Dryer For Sale
There are 5 pcs electric drain valve in our compressed air dryer for sale. Besides, they’re the Dutch Jorc brand. Therefore, they can remove water in the compressor dryer system in time. In addition, this water-cooled air dryer is with a unique water separation device. Due to the multi-stage separation, the water removal efficiency is over 99.9%. So it can ensure that our air compressor air dryer system get really dry air.
(5) Work Together With World Famous Screw Compressor Brands
Our compressor dryer system focuses on highly cost-efficient. Lingyu is one of top 5 compressed refrigerated air dryer manufacturers in China. Besides, our refrigerant dryers usually serve customers with well-know brands. Such as Atlas Copco, Ingersoll Rand, Kaeser, Hanbell, etc.
What is Water-cooled Air Compressor Air Dryer System
As the name suggests, it uses water cooling. Refrigerant through the water condenser of compressed air dryer for sale. Then exchanges heat with low temperature water. So as to achieve the purpose of cooling. Therefore, it can ignore the influence of the surrounding environment. Especially it’s suitable for working occasions over 40 ℃.
(1) How Does Water-cooled Refrigerator Air Dryer Work?
The compressor discharges high temperature and pressure refrigerant vapor. Then enter the water-cooled condenser. They exchange heat with cooling water. The refrigerant gas absorbs the cold and condenses into a liquid. Afterwards, flow out from the liquid outlet pipe. Cooling water goes through the pipe. In order to increase the heat exchange effect, it usually use finned copper tubes.
The inlet and outlet of cooling water are on the same side. The entrance is down and the exit is up. There is a water diversion rib inside. So it forces the cooling water to flow from bottom to top.
(2) Advantages of Water-cooled Refrigerant Air Dryer
- Firstly, it is suitable for various harsh working situations. For example, it is applicable for high temperature or dusty places.
- Secondly, under the same air capacity, the power of the water-cooled dryer is lower. So it’s more energy efficient.
- Thirdly, the pipeline vibration of air compressor air dryer system is low. So the noise is low and the structure is stable.
- The cooling effect of water is better. So the dew point of compressor dryer system is more stable.
- If the same air specification, the volume is smaller than the air condenser.
- In addition, it can meet the requirements of higher air capacity. For example, a customer needs a 300m³/min refrigerated dryer. At this time, if it is air-cooled, the machine volume will be very big. Besides, it will also be very expensive. But water-cooled compressed air dryer for sale will be not.
(3) Air-cooled Air Dryer vs. Water-cooled Air Dryer
- Heat exchange efficiency of these two compressed air dryer for sale
The specific heat capacity of water is 4.2kJ/(kgK). But air is about 1.4kJ/(kgK). This means that water absorbs or emits about three times as much heat as air. In summer, most water-cooled air dryers can keep the temperature at 32℃. But the air-cooled dryer is greatly affected by the ambient temperature.
So the heat transfer intensity of the latter is higher than the former. The water-cooled compressor dryer system is also not easy to stop in summer.
- Structure size of the two air compressor air dryer system
Water cooled condensers are shell and tube type. It is horizontal design. So the structure is compact. But air-cooled condenser is a finned tube type. And it also needs cooling fans. It requires large heat dissipation area. So it’s much larger in size.
Therefore, if it’s compressor dryer system, usually choose the air-cooled type. However, if it’s big refrigerant air dryer, it is best to choose a water-cooled type.
- Operation ease of the two compressed air dryer for sale
Water-cooled dryers have high requirements on water quality. If the water quality is low, scale will form. As a result, the heat transfer effect will be reduced. So it’s time consuming to clean up.
But this is not the case with air-cooled air compressor air dryer system. Just clean the dust off the fins regularly.
- Application range of these two compressed air dryer for sale
The latter refrigerated dryer requires a cooling water and softened water. Therefore, the factory must install the water supply system in advance.
The former air compressor air dryer system has high requirements on the environment. Also needs good ventilation. If the ambient temp is very high, should pay special attention to select.
