Oil compressors

       Oil compressors are commonly used air conditioning compressors or refrigerator compressors, the cost is relatively low. There is lubricating oil in the compressor, so it can only be applied to the same refrigerant recovery in the equipment. If the type or type of lubricant is different, it will cause the refrigerant to be contaminated by different oils. In the refrigerant production industry, the refrigerant will have an irreversible effect on the purity of the refrigerant because it is mixed into the pure refrigerant.

       Note: oil compressors should pay close attention to the loss of compressor oil in the recycling process, timely replenish the compressor oil to prevent oil shortage in the middle of the compressor, and can not directly recover the refrigerant liquid. It is easier to burn the compressor.

       Oil-free compressor is often said that the cylinder does not require lubricating oil compressor, its moving parts mainly use some specially designed aerospace self-lubricating composite materials, this compressor is in aerospace Contouring technology has a wide range of applications, such as compressed oxygen, hydrogen and other flammable and explosive gases. The highly durable refrigerant recovery machine is suitable for CFC, HCFC, HFC and other refrigerants because it uses an oil-free compressor and has no lubricant contamination.

       Oil-free compressor main advantages: easy to use, long life, a variety of refrigerants, maintenance-free.

        The main disadvantage: the compressor is expensive.
