25/05/2021Environmental concerns related to the global warming potential of SF₆ are promoting a new generation of gas-insulated switchgear (GIS) based on environmentally friendly insulating gases. In this switchgear, vacuum switching technology is used for the LBS and much research effort has concentrated on the dielectric and thermal challenges [1, 2] this technology poses.

Mixture consisting of 46 % HFC-143a and 7 % HFC-125. A HCFC mixture consisting entirely of HCFCs, where the GWP - in accordance with the climate convention guidelines - is 0, since the mixture does not contain greenhouse gases. The real GWP value is 1,440. Mixture consisting of 50 % HFC-32 and 50 % HFC-125

gasbanor Insulated gas machinery in IsraelASCO's innovative ASCOSORB CO 2 Stack Gas Recovery Technology turns your vent flue gas into a usable and profitable source of CO 2.CO 2 gas won by an ASCO Stack Gas Recovery System is a by-product of flue gas production from boilers as well as from other flue gas sources offering an economic CO 2 source to any CO 2 consumer or reseller. ASCO, as a provider of complete CO 2 solutions, offers

Evacuation of SF6 takes place with the help of an oil-free compressor and dry running vacuum pump down to 1 mbar. Evacuated gas is stored in the customers gas bottle with a storage pressure of max 50 bar. Air evacuation Hose intended for air is connected to object via the supplied connection piece. An air vacuum pump with a capacity of 2.6 m³/h is used for evacuation of air from objects, down to a final vacuum of 1 mbar. SF6 filling Filling is easiest done with self-pressure from a gas bottle.

The minimum paid-up share capital required to complete the incorporation process is US$1; As a statutory requirement, an FME must appoint the LISRC Trust Company as registered agent in Liberia and must have a registered address in Liberia; A Liberian foreign maritime entity is not required by law to submit their annual audited financial statements.

The process is simple: The GAD-2000 automatically takes out the SF6 gas from the system, dries it independently and returns it to the gas compartment dehydrated. The highlight of GAD-2000: in contrary to standard systems on the market, the switchgear does not have to be disconnected from the mains during the process of gas dehydration! This reduces service efforts and maintenance costs as well as avoiding dangerous load distribution risks.

On-site SF6 recovery service is driven by a trailer which equipped with our full set of recovery, refilling, purification equipment and measuring instrument, drive to the substandard gas compartment, perform onsite shutdown and maintenance, directly recover unqualified SF6 gas, recycle and purify them to be qualified and then return to gas compartment, the

Maintenance requires technical expertise, which necessitates the technology transfer from the designer to local people. Sustainability depends on the awareness of local population to continuously support and maintain such initiatives. The project in Eritrea was shut down in 2003 mainly due to local political upheaval.

Sulfur Hexafluoride (SF6) the price of new SF6 gas has increased in price by as much as 600%!! Due to the above reasons, SF6 is used mostly in applications that allow reclamation as opposed to using it on equipment that requires release of the gas, only to be re-filled with virgin SF6. Low cost solution for SF6 gas recovery. Small
