 RDQH-60 RDQH-60 SF6 Gas Refilling and Recovery Device

  

   Product Introduction

  SF6 Gas Recovery Unit is an essential equipment for reclaiming and treatment of SF6 gas in the manufacture, installations and maintenance of SF6 electrical apparatus.

  RDQH-60/60/350 SF6 Gas Recovery Unit is developed by our Institute according to standard JB/DQ2588-90 of the Ministry of Electro-Machano Industry and DL/T 662-2009《specification for SF6 gas refilling and recovery device. Other than the essential functions of evacuation, gas refilling and reclaiming and storage. It provides the following features as well:

  •    With the adoption of the international advanced liquefied refrigeration theory in the design, the working pressure in the system is reduced, while the actual efficiency of reclaiming is enhanced.
  •    With the provision of a self regenerative dry-type filter, the water content after primary reclaiming is less than 40 PPM by volume.
  •    It is capable of filling liquefied SF6 gas into the steel cylinder.
  •    The operation is simple and clear as the flow chart is drawn on the faceplate.
  •    The 3-phases power main in the electric system is self affirmed and adjusted.
  •    The whole device is to be air cooled and mobile, thus it can be operated at any site lack of water.
  •    It has a compact configuration.
  •    It’s sound level is bellow 75db(A) and a weight of less than 890Kg.
