The refrigeration of the refrigerated compressed air dryer first needs to adjust the vacuum drying cabinet. The oxygen must be injected after the temperature is cooled below the combustion point, otherwise the oxidation reaction will occur and further combustion will occur. When the interior of the vacuum dryer does not need to be extracted several times, the vacuum valve should be closed first, and then the refrigeration switch of the refrigerated compressed air dryer should be opened.

Everyone should be familiar with the refrigerated compressed air dryer, which is an important equipment with a wide range of applications. There are many types of dryers, and the dryers used in different industries are also different. Let everyone know how to open the refrigeration of the refrigerated compressed air dryer! There are many ways to use a refrigerated compressed air dryer.

1. When taking out the frozen samples, the samples that are easy to burn are frozen. After the temperature drops below the burning point, oxygen can be injected to avoid further combustion caused by oxidation reaction.

2. When the vacuum box of the vacuum dryer does not need to be used continuously, the vacuum valve must be closed, and then the main power supply in the middle of the vacuum pump must be closed, otherwise the vacuum pump oil will be returned to the interior.

3. If the drying time is long and the vacuum degree drops, it must be pumped back to the original vacuum degree again, the middle button of the vacuum pump must be pressed, and the vacuum valve must be released again.

4. It is strictly forbidden to place samples that are prone to explosion to dry.

5. After the vacuum is cancelled, the box door should not be opened due to the compactness and deformation of the internal hardware. It takes about 30 minutes to continue to open the box door.

The refrigeration dryer can operate the refrigeration service mainly because of its four components, namely the condenser compressor, the condenser rental, the condenser evaporator, and the expansion valve.
