Oil-free compression
There is not one drop of oil in the entire compression chamber to come into contact with the medium to be compressed. Oil contamination from the compressor is not possible.


Gas tight
The compressor is permanently technically tight. By using a special electric motor that is operated in the gas chamber, a non-contact magnetic clutch is dispensed with on the drive. The detachable connections on the compressor are all permanently technically tight through the use of O-rings and compression fittings. The gas lines of the intermediate and final stages are connected gas tight to the suction line.

Equipment
Piston compressor:   oil-less, hermetically gas-tight, direct drive without magnetic coupling,
1 or 2-stage compression, 2-cylinder, air cooled
Block cooler:   for efficient intermediate and final cooling of the compression medium
Air cooling fan:   cools compressor and condenser unit using ambient air
Pipe connections:   with compression fittings that provide a gas-tight seal even after repeated opening and closing
Base frame:   for installation of all components and for the flexible mounting of the compressor on a vibration-damping mat
Unloaded start-up:   the gentle, pressure-less start of the compressor and relief of the pressure after the compressor stops
Safety valves:  

in the intermediate and final stages in a gas-tight design to safeguard the compressor components against excess pressure; a safety valve on the crankcase venting freely into the environment
Check valve:   in the compressor outlet to prevent backflow of gas from the pressure side into the compressor
Options:   PT100 temperature control, pressure transmitter, pressure gauge, terminal box, electric control unit

SF6 – a dangerous gas for the environment

SF6 gas is a colourless, tasteless, and basically non-toxic halogen compound that, as a greenhouse gas, has a very negative impact on the environment. It can remain stable in the atmosphere for up to 3200 years. Its greenhouse effect is 23,900 times greater than the same amount of CO2. In the Kyoto Protocol of 1997, SF6 is listed as one of the six greenhouse gases that is forbidden to be allowed to escape into the atmosphere.

Using SF6 safely and preventing it from escaping into the atmosphere are important environmental themes for our society.
It is vital to support the safe use of SF6 and promote a clean recycling of SF6 gas by using gas-tight compressors.

Hermetically sealed compressors in SF6 recovery plants
Thus it is key to use a permanently gas-tight compressor for compressing SF6, or a hermetically sealed compressor. HAUG sets new standards for gas tightness, quality and process reliability with the new TUG compressor.

The use of SF6 gas in GIS (Gas-insulated Switchgears)
SF6 is excellent for electrical insulation and quenching switch arcs. To date, SF6 has almost entirely replaced oil and air as an insulating medium for high voltage switches. With the rapid increase of global electricity supply and the distribution of SF6 filled GIS the need for SF6 will increase steadily.
