Single-stage turbocompressors with a large turndown range
This company’s STC-DO single-stage, direct-drive turbocompressor utilizes a high-speed motor with the impeller mounted directly on the shaft. The compressor features turndown to 35%, which is said to be the widest turndown range in the industry. Tailored for use in wastewater treatment in both industrial and municipal settings, the compressor features a flow capacity range of 1,000 to 13,000 m3/h, and differential pressures up to 1.1 bars. The machine is 100% oil-free and comes with electrical filters as standard. The turbocompressor also boasts low noise production with no pressure pulsations. The company’s DualPoint control process allows for independent regulation of the flow and head of the compressor, providing efficiency even at off-design conditions.
