Research And Development

MANY FIRMS AND INSTITUTIONS use Sauer compressors in a variety of areas, while conducting research and development. Regardless of whether sensitive gases are in use, modern materials are being tested or complex processes play an important role, Sauer compressors are sound choices for any application since, they have been operating without problems for many decades.

Customers value our understanding of industrial applications and our ability to come up with exactly the right type of compressor, to suit their requirements, for example: the majority of universities rely on Sauer compressors, with regards to helium recovery.

ELGI Sauer customers benefit from the following advantages
  • Latest compressors, control systems, compressed-air treatment systems and accessories
  • Optimum customer services right from initial enquiry and extending throughout the product's life.
  • 100% compressor check at final pressure including 3.1 inspection certificate
  • Long operating life with guaranteed availability of replacement parts (minimum 25 years)
  • Turn-key solutions produced in keeping with customers' specifications
  • Great reliability, even during intermittent operation
  • Optimum customer and compressor care concepts
 

Engine development

Many customers are familiar with Sauer compressors through their role in shipping like the starting of diesel engines among others. However, many people do not realise that Sauer compressors also play an important role in testing these engines and developing new ones. They are therefore widely used on engine test beds. Furthermore, Sauer compressors can play a role in the development of gas engines such as natural-gas engines.

Research institutions and universities

The fact that universities as well as state and private research institutions perform extremely demanding work indicates that they rely on top-quality components, in order to achieve highly accurate results. Downtime and extended experimental periods reduce competitiveness and waste funds that have been allocated for research purposes. In the field of helium recovery and liquefaction, Sauer compressors can optimise the process, with a maximum leakage rate of just 0.1 mbar x l /s. Their economical design comes into its own, in ultrasound tests in wind tunnels or vehicle crash tests – the two applications which require high volumes in an extremely short period. Sauer compressors save time and reduce costs, making it possible to carry out more tests at shorter intervals.

Laser metal cutting

The cutting of metals with the help of a laser has replaced traditional mechanical methods and offers clear advantages. For example: the processes involved are shortened and the cut surfaces are not contaminated by the material of the cutting dies. However, the laser environment must be free from ambient air, if an optimum cut is to be achieved. To ensure that this is the case, nitrogen is used. This nitrogen is preferably produced on site, using the pressure swing adsorption (PSA) process or membranes. This helps to ensure that companies are not reliant on gas suppliers. After the PSA process has been carried out, Sauer compressors are used to boost the nitrogen to a pressure of 40 or 300 bar.

The higher pressure of 300 bar offers particular advantages as it enables large amounts of gas which are normally sufficient for a number of days, to be stored quickly. Not only do users benefit from greater operational reliability, they do not need to operate their high-pressure compressor for such long periods and can therefore take advantage of the times, where cheaper energy tariffs apply. Added to this, less extra equipment is required upstream, when a pressure of 300 bar is used.

Nitrogen – generation and storage

Nitrogen plays an essential role in many other applications as well. Sauer compressors are popular choices, when it comes to storing large amounts of the gas so that it is available quickly and in sufficient quantities, while carrying out the desired processes. There is a good reason for this. Each Sauer gas compressor is engineered to offer the high level of flexibility required, to satisfy an extremely wide range of requirements such as different suction pressures, final pressures or gas quality. As a result, they are frequently used in a variety of medium and high-pressure applications.

Manufacturing composite materials

The manufacture of composite materials is also part of the processing industry. In both the wooden materials and plastics industry, different materials are pressed together, under the influence of pressure and heat, in order to produce materials with special characteristic properties. In the field of plastics, so-called autoclaves (special pressurised containers which can be sealed to make them gas tight) are used. Sauer compressors offer an efficient way of ensuring that the necessary pressure is available for these processes.
