SHX - SF6 Gas Recovery Units

Sulphur Hexafluoride (SF6) is a compound that has a unique combination of properties, such as:

	Chemical Inertness
	Thermal Stability
	Non-Toxicity
	Excellent Heat Transfer
	Non-Flammability
	High Dielectric Strenght
	Non-Corrosive
	Ability to Regenerate

that have seen it applied in a wide variety of industries, amongst others:

	Magnesium Casting
	Aluminum Degassing
	Leak Detection
	Electrical Components
	Particle Accelerators

In the electrical industry the gas is used primarily in circuit breakers, puffer breakers (where SF6 used in place of air, oil or vacuum), switches and gas Insulated transmission lines

SF6 does have a number of disadvantages that are becoming more and more critical to an enviromentally-aware population.

Sulphur Hexaflouride is considered to be a fully flourinated compound (FFC). Since FFC's have atmospheric lifetimes of up to 50,000 Years, these potent greenhouse gases could contribute significantly and, essentially, permanently to global warming if emissions continue to grow. If CO2 has a global warming potential of 1, then SF6 has a global warming potential some 25,000 times higher.

The SHF-series of SF6 recovery units is designed to minimise the impact of these means of the following:

	Greenhouse gas reduction - through transfer of the SF6 from its
	current housing to onboard or external storage cylinders the gas does
	not need to be vented into the atmosphere

	By-product removal - by use of suitably designed filters and scrubbers
	its is possible to remove hazardous contaminants from the SF6 gas.

	Cost reduction - by effiently recycling the gas through the SHF recovery
	unit it is possible to reuse the existing SF6 gas minimising the requirement
	of purchasing new gas.
