Sulzer’s HSR line of high-speed turbocompressors is designed for the production of oil-free pressurised air in applications where contamination of the air must be avoided. The HSR utilises high-performance turbo and magnetic bearing technology that maximises the efficiency and minimises the need for maintenance.
A key benefit is that the HSR contains no oil at all. This means 100 % safe compressed air for processes where no contamination is allowed, for example in the production of fibrous materials or pharmaceuticals.
A key technological choice is the use of active magnetic bearings that bring the benefit of no mechanical friction and no mechanical wear. Together with the almost total absence of vibration, this grants the product a long lifetime. The HSR is cooled by water. The advantage is that both the heat generated by the compression and drive-related losses can be recovered as usable energy. Water cooling also ensures optimal perfor-mance and generally extends the lifetime of the components.
