The HST 30 is the newest addition to Sulzer’s HST line of high-speed turbocompressors. It offers more flow and pressure at a significantly higher efficiency than its predecessors. This translates into big savings in the energy consumed by low-pressure air compression, both in wastewater treatment and industrial processes. The HST turbocompressor line is the most popular choice in its size range today. With the addition of the HST 30, Sulzer offers the customers the best efficiency for an even wider range of flow and pressure. HST 30 builds on field-proven technologies of the previous Sulzer third generation high-speed turbocompressors. It incorporates both near-silent operation, uniquely efficient air compression, and an advanced but easy-to-use control system.
HST 30 introduces updated versions of the active magnetic bearings that are becoming the industry’s first choice in this size range. It also includes a new permanent magnet motor design, built specifically for this duty. Almost unique for this size of a machine is that it is cooled with air only, meaning there is no liquid to mix, fill up, check, or exchange. Better still, there is nothing that can leak, freeze, or boil off.
All cooling air filters are well protected by the front door, but can easily be exchanged in seconds. Thanks to the horizontal shaft and inlet direction, also the replacement of integrally-geared turbos and multistage centrifugal machines is straightforward. The flexible pipework configuration is helpful for the designer and builder as well. With filter boxes for wall or floor mounting as well as silencers and valves for all relevant flange sizes, HST 30 is one of the most flexible machines of its kind both for new builds and replacements.
