FTHS Series Gas Handling, Recovery and Re-filling Machine designed and produced by FUOOTECH is widely used in SF6 gas insulated electrical equipment factory, use, operation, scientific research departments and so on, to create vacuum for a variety of electrical equipment, and fill electric equipment with SF6 gas, and recover SF6 gas from use or test equipment, then fill to storage tank after purifying and compressing.
The recovery device is suitable for SF6 electrical appliance and GIS combined electrical apparatus. The gas recovery unit of SF6 is manufactured on the basis of the standard of DL/T662-2009 "SF6 gas filling and recovery device", which consists of recovery system, and inflating system, vacuum system, purification system and gas storage system.
Main Functions
1). Vacuuming and Measuring the vacuum degree of the device and electrical equipment;
2). Recycle the gas in the electrical equipment;
3). Dry and purify SF6 gas recovered and refilled;
4). Inflate SF6 electric appliance;
5). Compressed storage and bottle filling of SF6 gas in electrical appliances.
1) Advanced design, full function and compact structure with simple operation.
2) Compressed systems: it takes closed compressor to ensure no leakage.
3) Vacuum systems: it takes rotary vane vacuum pump to prevent oil returning
4) Purification systems: Equipped with special filters which takes electric heating and high efficient
adsorbents. Without frequent replacement of the adsorbents, so the purification result is better.
5) Electric systems: Equipped with reliable three phase power devices and automatic protection of phase break in the electrical system of the device, failure protection.
6) Control systems: adopts SF6 special valve with the latest technology.
7) Storage system: Provide the storage tank according to user's requirements.
