Air Liquide advanced Technologies’ Turbo-Brayton technology is an innovative, reliable and efficient solution for cryogenics, designed to save energy. It guarantees a continuous, highly reliable, energy-efficient and 100% oil-free operation.
The assembly of all active elements on the same shaft is the heart of the innovation. The recovery of the expander mechanical power, the centrifugal compressor and the direct drive high speed motor lead to a high overall efficiency.
The operation is very flexible, and the cold power can be adapted from 0 to 100% by changing the rotation speed of the motor, keeping high efficiency on a large range of operation (97% of nominal efficiency @ 50% of nominal cold power). This is particularly adapted to processes where the need for cold power is not constant and where energy saving and reliability are key issues. The MTBF (Mean Time Between Failure) of the Turbo-Brayton is 105 000 hours and the time between maintenance is 5 years.
The system is supplied as a single skid, ready-to-run package with a small footprint, mainly composed of:
Maximum energy savings – All components of the turbo-Brayton systems are designed to be both flexible and energy efficient (up to 40 % of Carnot efficiency). Enjoy extra energy savings with integrated Variable Speed Drive technology, which automatically tunes the motor speed to the cold power demand.
High reliability – Thanks to innovative magnetic bearings, low vibration turbo technology and integrated Variable Speed Drive, Turbo-Brayton systems provide exceptional reliability and production continuity.
100% oil-free and environmental friendly process gases – No risk of damage due to oil contamination, no risk of losses from operational downtime thanks to maintenance-free technology.
Easy installation – The integrated design of Turbo-Brayton systems includes internal piping, coolers, motor, and control system: all supplied as a ready-to-use package. Installation is fault-free, commissioning time is low and no external instrument air is required. You simply plug and run.
Care free systems - One of Air Liquide’s key concerns is to deliver a product that guarantees maximum uptime, in order to keep your system running.
Extremely low life cycle cost - Our solutions are developed to set costs at their lowest level, considering investments and operation costs.
