Air

The availability of sterile air is essential for a number of industries, including the food industry, pharmaceuticals, medical technology, life-sciences and bioprocess engineering, packaging processes and general processes with the highest requirements for air purity. Wherever viruses, germs, pyrogens, endotoxins and bioburdens in general are to be avoided, mobile or stationary sterile air generators are now used to produce sterile air from ambient air. As part of a configuration, a compressor or air compressor transports the air into the sterile area through a multi-stage filter package and from there into the space to be ventilated.

The accumulation of germs, spores, fungi and dust on the filtration material over time leads to a reduction in the air flow rate and an increase in pressure requirements, which greatly reduces the service life of the system.

Highly efficient air-bearing turbo compressors provide a remedy for this, by meeting the constant demand for extended service life, reduced system size, guaranteed impurity-free air and reduced energy requirements. Compared to conventional scroll or side-channel compressors, our turbo compressor systems are up to 30 times smaller, lighter and very quiet and feature an impressive miniaturized design and significantly higher pressure ratio. This allows filters to be operated for much longer and the low installation space and low weight result in reduced system dimensions. In addition, the turbo compressor is considerably more efficient compared to conventional compressors, which significantly reduces operating costs and total cost of ownership.

Space

The space industry has different requirements than conventional industries. The focus is on particularly compact and lightweight designs as every cubic centimeter and every gram saved leads to significant cost advantages. This is a decisive factor in this extremely cost-intensive industry. In addition, high reliability and a long service life are crucial.

A key issue in manned spaceflight, and in future also for Lunar or Martian habitats, is the Environmental Control and Life Support System (ECLSS). These systems make enclosed spaces habitable for humans in the first place. In addition to regulating the temperature of the interior, ECLSS also includes the treatment of breathing air, which is essential for survival. This is often ensured by the Air Revitalization System and the Oxygen Generation System. When treating breathing air, it must be ensured that there are no contaminants in the air.

Celeroton’s turbo compressors offer an ideal solution for such specific systems. Thanks to the air bearings, the turbo compressors are oil-free by design, which reduces deposits in piping and components and significantly lowers the risk of contamination in the cabin air. In addition, the compressors operate contact-free, allowing for a significantly longer service life and exceptional high reliability.

One example is the CO₂ scrubber in the Air Revitalization System, which continuously removes carbon dioxide from the breathing air. The necessary air circulation is reliably provided by Celeroton’s turbo compressor.

Thanks to gas bearing technology, the turbo compressors operate contact free. Allowing for operation at very high speeds, resulting in an exceptionally high-power density. In addition, the inherently stable gas bearing technology eliminates the need for an additional control system that could fail.
