HSR turbocompressor for truly oil-free airA leading European food company has been manufacturing and selling various types of high-quality pork, beef, poultry and lamb products. A few years back, the production processes of the client were improved by the installation of a high-speed turbocompressor in one of the meat factories. It delivers 100% oil-free compressed air for the distribution network.
Magnetic vs. air foil bearingsThe turbocompressor has become a mainstay of modern water treatment technology, offering a mechanically simple design, reliability and good energy efficiency. Ideally suited for the production of large volumes of compressed air at relatively low pressure, they rely on bearings that can spin at high speeds with minimal resistance and for extended periods. Today, the market is dominated by two rival technologies: air foil bearings and active magnetic bearings.
HST™ and HSR high-speed turbocompressors for truly oil-free airToday, we are increasingly concerned about the environment and sustainable development. Industries are looking for solutions that reduce both energy consumption and carbon footprint – and at the same time increase equipment efficiency and reliability. When it comes to the production of compressed air, all this can be achieved with Sulzer’s centrifugal air turbocompressors driven by an electric motor. Sulzer’s product range includes turbocompressors for both low-pressure industrial applications (HST) and industrial compressed air supply networks (HSR).
High-speed compressors for industrial applications ─ HST™ and HSRSulzer, well known for pumping and mixings solutions for several industrial applications, has made great strides to supply air compression equipment to the industries that the company serves. It started with the addition of the renowned HST line of low-pressure compressors (blowers) 20 years ago. With the addition of the HSR compressor for oil-free compressed air, the range is now quite complete when it comes to pressures normally required in industrial processes.
Energy-efficient tissue line benefits from HSR turbocompressorThe Italian company Cartiera Confalone s.p.A. manufactures household and sanitary papers. In 2019, the company decided to build a new, energy-efficient tissue line in Montoro, Avellino. The mill produces jumbo rolls in pure cellulose destined to the converting process for transformation into toilet paper, industrial rolls, kitchen rolls and napkins. Cartiera Confalone s.p.A. has another paper mill close by, in Maiori.
Air for efficient aerobic biological treatmentNorske Skog Boyer Mill in Tasmania is a TMP newsprint mill that has produced paper continuously since 1949. A wastewater treatment plant comprising a central moving bed bioreactor (MBBR) and outer activated sludge tank (AST) treats up to 25’000 m³/d of process effluent. Four sets of HST™ turbocompressors play an essential role in the supply of air for efficient aerobic biological treatment. The compressors feed nine subermersible OKI aerator mixers in the AST and the aeration grid in the MBBR.
Driving up efficiencyThe adoption of electric vehicles across the world is increasing rapidly and this demand needs to be matched by the supply of batteries. As new processing plants and manufacturing facilities are constructed, it is important that they employ the latest in pumping technology to ensure optimum reliability and efficiency.
