6.5m³/min 200 CFM Air-cooled Refrigeration Air Dryer

We are the best compressed air dryer manufacturer in China. We focus on air treatment equipment for more than 13 years. So we can supply best air compressor dryer quality and price. Refrigerated air dryer and desiccant dryer are the main products. And this dryer is high temp type. It’s air capacity is 6.5m³/min. That is, more than 200 CFM. It is suitable for 50 HP air compressor.

Refrigeration dryer is an important air purification machine. It uses the principle of physical cooling and dehumidification. That is, the refrigerant will evaporate and absorb heat. At the same time, moisture will condense into a liquid state. Finally refrigerant air dryer will discharge the water. So it can achieve the desired dew point.

Technical data sheet of our best refrigeration compressed air dryer

Why choose our best air compressor dryer?

(1) High quality refrigerant compressor

The refrigeration compressor is the heart of air dryer. This best compressed air dryer uses one of the most famous refrigerant compressors. That is, the Panasonic brand originating in Japan. It not only has super cooling efficiency, but also has low noise. Besides, it has built-in security. So the working performance is very stable.

(2) Two-stage pre-cooling

The first-stage is the pre-cooler in this 200 cfm air dryer. And second-stage is the heat exchanger. So the compressed air can be initially cooled. It can also remove some water.

Afterwards, the compressed air comes to the evaporator. At this time, its temperature will not be too high. Therefore, the refrigerant compressor will not work at high load.It can avoid high temperature shutdown.

(3) High quality raw materialsand parts

This best air compressor dryer uses 5.0mm thick copper pipes. In addtion, the heat exchanger fins are made of hydrophilic aluminum foils. It ensures high heat exchange efficiency of our best compressed air dryer.

There are 4 sets of external rotor fans in the 200 cfm air dryer. Compared with the internal rotor fan, the air volume is 35% larger. Moreover, the lifespan is at least 3 times longer. Protection class is IP54. So it is more safe, reliable and durable.

(4) With multiple protection, more secure

The refrigerant compressor has its own overload protection. In addition, there is refrigerant high and low pressure protection. They can prevent refrigerant leakage. At the same time, can protect the compressor.

Besides, there are also other protection devices, such as overheating, overcurrent and undertemperature protection. Therefore, the operation of our refrigeration air dryer is safer.

To sum up, our air compressor dryers have reliable quality. Of course, we also supply good refrigerated air dryer price. That’s why we are the best compressed air dryer factory. 

Moreover, our dryers usually work with many famous air compressor brands.

How does the refrigeration air dryer works?

It uses refrigeration equipment to cool compressed air. And reach a certain dew point temperature. At the same time, it can condense corresponding water. Then carry out air-liquid separation. Finally, the water is drained by the automatic drain valve. So as to achieve the purpose of freezing and dehumidification.

In addition, the filter will remove dust particles and oil. So that the air can meet the requirements of clean and dry. Below we will introduce the working principle of our best compressed air dryer.

(1) Air system of the refrigerant air compressor dryer

Before drying, compressed air contains lots of moisture and oil. First of all, they enter the air-to-air heat exchanger. There will perform initial cooling.

Then, it enters the air-to-refrigerant heat exchanger. That is, the evaporator of best air compressor dryer. Allow the compressed air to cool further. At this time, the dryer can reach a dew point temperature ~ 2-10 °C. Because of the low temperature, water and oil will condense. They will beseparated and discharged from the machine.

Finally, the compressed air is dry. But its temperature is also low. If it discharge directly, there will be a phenomenon of “condensation” in the pipeline. To avoid this, it needs to warm up. So the compressed air goes back to the heat exchanger. They will output after warming up.

(2) Refrigeration system of our best compressed air dryer

Initially, the refrigerant in the evaporator is low temp liquid. But they will absorb the heat of compressed. So they will evaporate into gas.

Then, the gaseous refrigerant returns to the compressor. Afterwards, the compressor generates high-pressure refrigerant gas. They will flow through the condenser. At this time, the gas will become liquid refrigerants. Finally flow back to the evaporator of best air compressor dryer. So start a new round of heat exchange.

FAQ

(1) What is the outlet temperature of your best compressed air dryer?

After evaporation, we will get dry low temperature compressed air. But we won’t exclude them directly. Instead, they will go back to the heat exchanger. Warm up first, then exhaust. So the dryer outlet temperature is generally affected by three factors. That is, inlet temperature, inlet pressure and heat exchanger size. Generally, the outlet temp will be about 5~15°C lower than the inlet air temperature.

① The heat exchanger size of refrigerant dryer

The low temperature dry air return to the heat exchanger. It will come into contact with inlet high temperature and humid air. Its size will determine the contact area and time. The better the contact, the higher the outlet temperature. Assume that the inlet temperature is 40°C. If the volume of the heat exchanger is larger, the heat exchange time of dry and wet air will be longer. The final outlet temperature will be close to 40°C.

However, it is not that the larger the heat exchange area, the better. Otherwise, it will waste resources! That is, it will increase refrigerated air dryer price.

② Inlet air temperature and pressure of the best air compressor dryer

The higher the intake air temperature, the higher the outlet air temperature. Additionally, the low pressure can help the dry air to warm up.

In recent years, the 3-in-1 plate exchanger refrigerated dryer has become more and more popular. In fact, it is because the heat efficiency is higher. It also performs well in the temperature recovery efficiency. Usually, the temperature difference between the inlet and the outlet is about 5 °C.
