Magnetic vs air foil bearings Finding the best bearing solution for water treatment blowers

The 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. 

Edward Paro of Sulzer compares their strengths and weaknesses.

The rotor at the heart of a turbocompressor is powered by a high-speed electric motor, usually with no intermediate gearing. In operation, the motor shaft and rotor assembly spin at speeds of up to 50’000 rpm, and may operate continuously for extended periods between overhauls. Those conditions require a special type of bearing, and two approaches are commonly used in modern turbocompressor designs.

Reavell launches new nitrogen boosting system

High-pressure compressor manufacturer, Reavell, part of the Ingersoll Rand Group, has launched Boost, a plug-and-play range of four nitrogen boosters.

Designed for easy integration with any nitrogen generation system, the four models (H075, H110, H150 and H185) deliver up to 350 bar pressure outlet and flow rates up to 56 m3/hour on the H185 model.

On-site nitrogen generation has been gaining popularity over recent years, using existing compressors to convert air to guaranteed purity nitrogen. The process can save operators up to 90 per cent of the cost of bought-in gas with payback in less than two years for a company using liquid nitrogen, or as little as one year where gas cylinders are being used. 

Vert Technologies’ free loan of compressor helps hand sanitiser bottler meet air power needs

Young Spirits, a Scottish spirit bottling business which has switched operations to produce much-needed hand sanitisers to fight the Covid-19 outbreak, has benefitted from a free loan offer from leading-edge compressor manufacturer, Vert Technologies. 

Vert’s offer of short-term compressors free of charge to manufacturing companies that need air for one or two production machines, is designed to help struggling Scottish businesses cope with the downturn.

i.safe MOBILE presents Android tablet for robust use in hazardous areas

i.safe MOBILE, a developer of mobile communication devices in the hazardous zone 1/21, has announced the IS930.1. The IS930.1 combines the indestructible robustness of an IP-certified tablet with ATEX and IECEx approvals for safe use in hazardous environments.

It can be used in the oil, petrochemical, pharmaceutical and food industries as well as in mining, public utilities, municipalities and energy suppliers, among others. The IS930.1 comes with an 8” large, capacitive and low-reflection screen made of RugDisplay glass with a maximum resolution of 1,920 x 1,200 pixels, which is easy to read even in direct sunlight.

NexSys® ATEX batteries bring advantages of Thin Plate Pure Lead (TPPL) technology to materials handling vehicles operating in hazardous areas

NexSys® ATEX batteries, available from EnerSys®, allow materials handling vehicles to work safely in hazardous areas where there is an explosion risk. They conform to ATEX standards, which are compulsory and a legal requirement in Europe and NexSys® batteries are also available world-wide certified in compliance with IECx standards. 

The new batteries, available in nearly all DIN sizes and capacities, offer significant advantages over both Valve Regulated Lead Acid (VRLA) gel and flooded lead-acid solutions. These advantages result from the Thin Plate Pure Lead (TPPL) technology used in the batteries’ construction. Accordingly, they offer outstanding Amp-hour (Ah) capacity.
