Germany’s Sauer Compressors has launched the HAUG Sirius NanoLoc, the first compressor to combine two of the company’s core competencies: high-pressure know-how and oil-free expertise. The completely dry-running and hermetically gas-tight solution is designed for applications that require absolute process safety and purity, said the company that develops, produces and sells medium- and high-pressure compressors.

With final pressures of up to 450 barg, the compressor offers oil-free compression of virtually any gas, Sauer said.

With the integration of the former HAUG Kompressoren AG, Sauer Compressors has significantly extended its portfolio to include solutions by the industry’s leading expert in oil-free air and gas compression. The HAUG.Sirius NanoLoc marks the latest addition to the product range and is the first compressor that combines high pressure with oil-free compression.

Oil-free for highest gas purity

Both the crankcase and the compressor stages operate without any oil. This ensures highest gas and process purity. Therefore, the compressors are an ideal choice for sensitive applications such as industrial gases, medical applications and bio technology as well as the chemical, pharmaceutical and food industries.

Final pressure of up to 450 barg

With its hermetically gas-tight construction, the HAUG.Sirius NanoLoc achieves extremely low leakage rates of <0.001 mbar l/s and enables 4-stage compression of almost any gas. The compressor delivers a flow rate of max. 66 Nm³/h and a final pressure of up to 450 barg with an inlet pressure of up to 30 barg. Depending on the configuration, it comes with a motor power of 11-30 kW. In addition, the HAUG.Sirius NanoLoc is ideally suited for booster applications of gases such as helium, natural gas or hydrogen.

Gas-tight magnetic coupling

The well-proven magnetic coupling drive adds to the machine’s exceptional gas-tightness both at standstill and during operation. The technology is a core feature of the HAUG.Sirius series. Due to the newly developed and unique NanoLoc® piston design’s friction-free sealing, wear and friction losses in the cylinders have been reduced significantly. Likewise, all the compressor’s components are designed for a particularly long service life.

Low-maintenance, high reliability

Even in operations with long standstills, frequent interruptions and cold starts, the HAUG.Sirius NanoLoc is highly dependable. The absence of oil serves to significantly lower operating and maintenance costs. Due to its unparalleled process purity, the compressor reduces the need for gas treatment and filtration after compression to a bare minimum. Often, treatment and filtration are not required at all, resulting in significant time and cost savings.
