QTHS Series SF6 Gas Recycling Equipment

The QTHS series sf6 gas recycling equipment adopts the principle of refrigerated liquefaction. That is, in the process of SF6 gas recovery, under certain pressure of SF6 gas, the refrigeration unit reduces the temperature of SF6 gas to the temperature of saturated steam under pressure, and SF6 gas begins to liquefy into liquid and is stored as a liquid.

What is SF6 gas recycling equipment?

The SF6 gas recycling device is used to evacuate various electrical equipment, fill it with SF6 gas, recover SF6 gas from the electrical equipment, and at the same time purify it and then compress it and store it in a storage tank.

Can SF6 gas be recycled? Is SF6 gas environmentally friendly? Can SF6 gas be destroyed by incineration?

Under normal temperature and pressure, pure SF6 gas is colorless, odorless, and basically non-toxic. But if the purity is not enough, mixed with toxic impurities, or under the action of high-power arc and corona discharge, SF6 gas will decompose to produce a variety of toxic substances.

Improper recycling of SF6 gas or leakage in the recycling process will pollute the environment, and will also adversely affect the normal operation of equipment and the health of personnel. Therefore, we should use SF6 Recycling Equipment to recycle SF6 gas.

Features of SF6 Gas Recycling Equipment:

  • QHTS series sf6 gas recycling device adopts designing principle from Germany DTL0 company, advanced design, compact structure, complete function, convenient operation.
  • The sf6 gas refilling device also adopts a dual-stage single-acting compressor, which can directly press SF6 gas into a liquid and store it in the tank in the equipment.
  • The vacuum system of the QTHS series sf6 gas refilling device adopts a dual-grade rotary vane pump high vacuuming speed.
  • Recovering system of the QTHS series sf6 gas recycling device adopts a single-grade rotary-vane pump (diaphragm pump). It has the feature of low recovery residual pressure and quick speed.
  • The filter inside the purifying system has a built-in vacuum electric heater and high efficient sorbent, better purifying result.
  • The equipment adopts a patent special SF6 valve. It is more reliable than ball valves used in similar overseas devices.
  • Storing capacity of the QTHS series SF6 gas recycling and refilling equipment can be as the customer’s requirement.
  • The equipment is movable, and the machine can do the air-cooling operation and does not need a water source.
  • We also offer other types of SF6 gas handling machines for you to choose from.
