SF6 gas is a halogen compound which has a very negative impact on the environment. The greenhouse effect for SF6 is 23,900 times as large as for the same quantity of CO2. SF6 gas is one of the six greenhouse gases which are prohibited from freely escaping into the atmosphere. The harmful effect on the environment makes the safe and gas-tight use of SF6 an important issue for society as a whole.  It is essential to use gas-tight equipment and gas-tight processes in connection with SF6.

HAUG compressors are ideally suited for compressing SF6 gas due to their oil-free, dry-running, hermetically sealed design, and non-contact magnetic coupling. The compressor is air-cooled. The scope of supply is adapted to the customer requirements and ranges from the compressor block to the completely piped system with control.

HAUG compressors offer:
  • no gas contamination and contamination of plants and equipment by oil-free compression
  • technically sealed gas compressors during operation and at standstill and thus no leaks to the environment
  • Application in gas recovery systems for the maintenance of high voltage switches
  • Application in industry and production facilities where SF6 is used

HAUG SF6 compressors are used throughout the world by leading manufacturers of SF6 recovery plants for gas-tight and oil-free compression.
Compressed air generated by oil-free compressors has many interesting applications. The oil-free compressors for the HAUG series operate completely dry, i.e. without lubrication of the cylinder and an oil bath in the crank mechanism. This prevents any contamination of the compressed air by the lubricating oil.

Fields of application for oil-free compressed air:
  • Hospitals - production of breathing air and air for the operation of surgical tools
  • Dentistry - as central compressed air supply
  • Pharmaceutical Industry - the production of medicines and process air
  • Chemical Industry - instrument and process air
  • Power Plants and Water Stations - control air
  • Research - air supply in the laboratory
  • Manufacturing - compressed air supply for production, packaging and processes

HAUG boosters have additional advantages:
  • They are very quiet and compact and can, therefore, be used as decentralized workplace compressors.
  • They are leak-free, thanks to gas-tight design and thus have no compressed air leaks.
  • They offer the best possible compressed air quality due to the oil-free compressor principle.
  • They have a low energy consumption due to the optimized torque curve.
  • They offer a better service life of the wear parts due to the gas-tight design.

Nitrogen is a very popular gas because it is cheap to produce and extremely inert. Nitrogen is used in industry as a protective gas.

Nitrogen is used in the pharmaceutical industry for the coating of tablets. Under protective gas atmosphere consisting of nitrogen with solvent, the tablets are coated in a closed process in a spray process. The spraying takes place via nozzles. These compressors are required, which compress the gas mixture to the nozzle form.

Nitrogen compressors are used in industry, where the existing nitrogen pressure is insufficient, for example, for use in laser cutting or for cleaning process filters with product gas in countercurrent process.

If gas purity and process safety are important, HAUG compressors offer the best possible conditions due to their oil-free, dry-running and gas-tight design.
  • no gas contamination by oil
  • technically tight, in operation and at standstill

Oxygen is one of the gases where oil-free compression is mandatory. It is also mandatory to clean the compressor "oil and grease-free" before handing it over to operation. This is related to the easy ignition of oxygen. Oxygen is a strong oxidizer. Foreign substances, oils, and fats can ignite in this environment, with the result that the compressor starts to burn. It, therefore, needs special knowledge to produce oxygen compressors. HAUG has been building compressors for oxygen since the 1980s.

HAUG oxygen compressors are often used as a re-compressor for on-site gas generators. Oxygen is generated by a PSA, VPSA or membrane plant. Depending on the process, the pressure downstream of the generating plant is at atmospheric pressure (VPSA) or around 58 psi (PSA). Depending on the application of oxygen then the pressure must be increased afterward. This is done by a re-compressor.

Oxygen applications in conjunction with an on-site gas generation facility are independent oxygenation in a hospital or mobile health care center, or oxygenation in remote areas, such as extraction of raw materials such as gold or metalworking.

Thanks to their oil-free, dry-running and gas-tight design, HAUG compressors are ideally suited for use in the compression of oxygen.
  • no gas contamination due to oil-free and dry-running compression
  • Safe operation through the use of special, oxygen-compatible materials
  • technically tight gas compressors during operation and at standstill

Natural gas is a naturally occurring gas that consists mainly of methane. Methane can also be produced by treating biogas. Alternatively, methane can also be prepared by synthesis from carbon dioxide and hydrogen. For example, with surplus electricity, hydrogen is produced first and in a second step natural gas, to store the energy in the natural gas network.

Natural gas is the most environmentally friendly combustion gas after hydrogen. A major advantage of natural gas is the existing infrastructure in the form of pipelines, natural gas networks and filling stations for vehicle refueling.

For environmental reasons, it is important to prevent gas leaks and use gas-tight systems. Methane is 25 times more harmful than CO2 and accounts for around 20% of the greenhouse effect caused by humans.

Examples of applications with natural gas compressors:
  • Application as leakage gas compressor for the recovery of leaks
  • Application as a booster for increasing the pressure of an existing natural gas network pressure, for
  • example for use as fuel gas in the surface coating
  • Application as a booster for charging gas engines
  • Use in the synthetic production of natural gas from hydrogen (power-to-gas)
  • Application for storing natural gas for vehicle refueling

Thanks to their oil-free, dry-running and gas-tight design, HAUG compressors are ideal for many natural gas applications.
  • no gas contamination by oil
  • technically tight, in operation and at standstill

Biogas is produced by the anaerobic fermentation of biomass, for example, residues from the food industry, waste, sewage sludge or renewable raw materials. In fermenters, biogas is produced from the biomass in anaerobic fermentation. Depending on the origin of the biomass, the gas composition of the biogas varies. A typical gas composition is 60% CH4 (methane) and 40% CO2 (carbon dioxide). The gas is humid (saturated with water) and contains pollutants like H2S. Moisture and H2S are removed in the pre-cleaning.

In the fermenters and the pre-cleaning usually low-pressure blowers are used. Compressors are needed if the biogas is to be stored or treated, so that the methane content is greater than 96%. The biogas treatment can be done by different methods. Practically all require a process pressure of 6 to 15 bar, which are generated by compressors.

Examples of biogas/biomethane compressor applications:
  • Preparation of biogas to biomethane
  • Feed into the natural gas network
  • Provision for vehicle refueling
  • Biogas cycle compression in fermentation
  • Biogas, biomethane and CO2 compression for storing excess electrical energy in the natural gas grid (power-to-gas)
 
Thanks to their oil-free, dry-running and gas-tight design, HAUG piston compressors are ideal for many biogas and biomethane applications.
  • no gas contamination by oil
  • technically tight, in operation and at standstill
  • flexible concerning variable suction and discharge pressure

Hydrogen is increasingly used as an energy source for reasons of environmental protection. Hydrogen can be produced from biomass via a synthesis gas. However, hydrogen is mostly produced by electrolysis. Depending on the method, the hydrogen pressure at atmospheric pressure is up to a maximum of about 435 psi. Compressors then compress to a final pressure where the gas is stored, for example in the natural gas network or vehicle refueling bundles or for industry.

Hydrogen is an important gas for industry and is used in numerous applications:
  • as cutting gas and welding gas in metal working
  • as a protective gas and coolant in the semiconductor industry and research
  • in the food industry and metal production as a process gas in production

Helium is a rare and expensive gas so it is worthwhile to recover and reuse helium after use. Helium gas reclamation is used in leak testing, for hardening processes in the metal industry, cryogenic technology, industrial process gas and in numerous research applications in industry.

The helium is collected at the highest possible pressure in a container and then compressed by a compressor to the desired storage pressure. The systems run in a closed circuit. Only used helium must be supplied. This saves a large part of the expensive helium.

Important in gas recovery are the gas tightness of the process and the gas purity. Soiling caused by gas leakage into the environment falsifies the measurements during the leak test. In helium heat treatment, impurities in helium are the cause of defects and quality reductions in the heat treatment process.

Thanks to their oil-free, dry-running and gas-tight design, HAUG reciprocating compressors are ideal for inert gas applications.
  • no gas contamination by oil
  • technically tight, in operation and at standstill
  • flexible with regard to variable suction and discharge pressure

For certain processes with refrigerant gases, there are great advantages when compressing with oil-free compressors. Especially for new refrigerants based on gas mixtures with hydrocarbons, the demands on the refrigerant compressors have risen massively. In addition to oil-free compression, there are also high requirements for gas tightness.

Fields of application:
  • Compression of ammonia
  • Densification or recovery of R410 and mixed gases thereof
  • Recovery of refrigerant gas during maintenance of cooling and process equipment (eg R134a)

HAUG reciprocating compressors have the best prerequisites for refrigerant gas applications thanks to their oil-free, dry-running and gastight construction.
  • no gas contamination by oil
  • technically tight, in operation and at standstill
  • flexible concerning variable suction and discharge pressure

Examples of applications with oil-free CO2 compressors:
  • In the beverage industry for CO2 enrichment
  • In breweries
  • Food and pharmaceutical industries as solvents in the supercritical state above 870 psi. For example, to remove caffeine from tea or coffee.
  • As natural refrigerant with a heat pump. Relatively high pressures of more than 100 bar are required for this application.
  • Storing excess electrical energy in the form of natural gas, which is synthetically produced from carbon dioxide and hydrogen. The carbon dioxide can come, for example, from a biogas upgrading plant and the hydrogen from an electrolysis plant. Thus, the synthetically produced methane can be stored in the natural gas network.
Thanks to their oil-free, dry-running and gas-tight design, HAUG compressors are ideal for many CO2 applications.
  • no gas contamination by oil
  • technically tight, in operation and at standstill
