Sulfur hexafluoride recovery and purification device is a necessary device used to recover and treat SF6 gas in the manufacture,installation and maintenance of SF6 appliances

　　.With a vacuum,inflation,recovery and storage of the general SF6 gas recovery inflation device prepared by the function,but also has the following characteristics:

　　1.Sulfur hexafluoride recovery and purification adopts the design principle of freezing-liquefaction method,which reduces the working pressure of the system and greatly improves the efficiency of recovery.

　　2.Refrigeration compressor optional semi-closed refrigeration compressor Emerson-valley wheel(the performance is far more than any original import of the same refrigerating capacity closed compressor).

　　3.SF6 compressor is semi-closed compressor,applied to SF6 and other halogen gas,with fluorine resistance,to ensure no leakage.

　　4.Double container system,SF6 can be liquefied,and can fill cylinders,filling volume is not less than 50kg.The bottle filling capacity of a single container recovery device is not less than 30kg.

　　5.Sulfur hexafluoride recovery and purification double container system has SF6 vaporization mode,the use of high temperature and high pressure SF6 gas,forced low temperature and low pressure SF6 liquid filling into the cylinder,short time,large amount of filling.

　　6.Use column level gauge,SF6 liquid level indicator is intuitive and accurate.The liquid level is backlit and clear.

　　7.The liquid storage container is equipped with high-power SF6 vaporizing electric heater.Automatic temperature control when using,so that SF6 fully vaporized external inflation.

　　8.Excellent oil mist filtration system ensures that the oil content reaches the standard.Compressor lubricating oil to ensure that one year does not need to add,oil level to ensure that does not fall.

　　9.Sulfur hexafluoride recovery purification molecular sieve drying system reliable performance.Molecular sieve regeneration without disassembly,disassembly and replacement,easy to use,only on the molecular sieve dryer for self-regeneration operation,drying performance can be restored as before.

　　10.Customized phase sequence protection device,withstand pressure up to 500V,greatly improve the reliability.

　　11.Sulfur hexafluoride recovery and purification three-phase power supply,the middle line is not necessary,the whole machine is equipped with leakage protector.

　　12.The flow chart is drawn on the panel,easy and intuitive to operate,all ball valves are used,and the open and close state is clear.

　　13.Air-cooled,mobile,can be used in the case of no water source.

　　14.The vacuum gauge is Pilani vacuum gauge with digital display.

　　15.Installation of sulfur hexafluoride gas device with good casters,easy to move,do not harm the ground.
