SF6 Portable Recovery and Filling Device
● The design principle of cryogenic liquefaction is adopted, which reduces the working pressure of the system and greatly improves the recovery efficiency.
● The refrigeration compressor can be optionally equipped with an original French imported fully hermetic refrigeration compressor. It can also be upgraded for free to a semi-hermetic refrigeration compressor produced by an American wholly-owned enterprise, Emerson-Copeland (performance far exceeds any original imported fully hermetic compressor of the same cooling capacity).
● The SF6 compressor is a semi-hermetic compressor produced by an American wholly-owned enterprise (Emerson - Copeland brand), applied to halogen gases such as SF6, with fluorine resistance characteristics, ensuring no leakage.
● The vacuum pump can be optionally equipped with a Japanese Ulvac two-stage rotary vane vacuum pump or a German original Busch, German wholly-owned Leybold, etc.
● Dual container system, SF6 can be liquefied, and can be filled into cylinders, with a filling amount of no less than 50kg. The filling amount of a single container recovery device is no less than 30kg.
● The dual container system has an original SF6 vaporization method, using high-temperature high-pressure SF6 gas to force low-temperature low-pressure SF6 liquid into the cylinder, with short time and large filling amount.
● A column level gauge can be used, and the SF6 liquid level indication is intuitive and accurate. The liquid level has a backlight indication, which is clear and unambiguous.
● The liquid storage container is built with a high-power SF6 vaporization electric heater. During use, automatic temperature control is performed to fully vaporize SF6 for external inflation.
● Excellent imported (American) oil mist filtration system ensures that the oil content meets the standard. The compressor lubricating oil ensures no need to add within one year, and the oil level is guaranteed not to drop.
● The molecular sieve drying system has reliable performance. When regenerating the molecular sieve, there is no need for disassembly, removal, or replacement, and it is easy to use. Only self-regeneration operation of the molecular sieve dryer is required, and the drying performance can be restored to its original state.
● All ball valves adopt the American Swagelok working principle, and the sealing elements have automatic compensation performance. They are practically applied to vacuum and pressure conditions, ensuring no leakage in both vacuum and pressure, and are special ball valves for both vacuum and pressure use. (American Swagelok original ball valves can also be selected).
● Customized phase sequence protection device, with a withstand voltage of up to 500V, greatly improving reliability.
● Three-phase five-wire power supply, safer and more reliable.
● The flow chart can be optionally drawn on the panel, which is convenient and intuitive to operate. All ball valves are used, and the open and closed states are clear.
● Adopting air-cooled, mobile type, it can be used in places without water source.
● The vacuum gauge is a digital display Pirani vacuum gauge.
