DRYER RENTAL SCHEME HI-LINE INDUSTRIES, a leading UK supplier to the compressed air sector, reports it has a solution for all companies seeking a temporary way of delivering high-quality, dry compressed air and says an affordable and responsive rental scheme is now in place at the company, covering its comprehensive range of classleading compressed air dryers. Although hiring a compressor can be easy enough for short-batch emergency runs or exceptionally busy periods, finding specialist drying equipment is not so straightforward, and yet air quality is just as important in temporary periods as it is during long-term regular operations. Hi-line says it overcomes this issue by offering hire options on a vast range of compressed air dryers, including refrigerant, heatless, heat-regenerative and point-of-use models. High-quality, competitive filtration packs can also be provided. The company says its market-leading Tundra refrigerant air dryers, for example, are renowned for their robust and reliable performance. Moreover, the newly improved single-cell heat exchanger gives the most efficient transfer of heat at the lowest energy cost. For those seeking heatless dryers, Hi-line can offer its proven HPSA (Heatless Pressure Swing Adsorption) units, which come in ‘plug and play’ format mounted on skids with their own filtration package as standard. t | 01283 533377 e | enquiries@hilineindustries.com w | www.hilineindustries.com KINETROL reports it has extended its product range with the addition of the Model 60 and says the new unit increases the company’s torque output coverage to over 40,000 Nm (350,000 lbf.in ) and broadens Kinetrol’s applications to include 16” ball valves and 2m butterfly valves. The company says the single vane actuator provides direct drive rotary control with the following advantages: the one moving part construction facilitates accurate modulation and increases life expectancy (guaranteed up to 2 million operations) space saving/energy absorbent side plates reduce compressed air/energy consumption and facilitate fast operation a new end-stop design further extends the actuator’s life. t | 01252 733838 e | sales@kinetrol.com w | www.kinetrol.com PRODUCT RANGE EXTENDED GENAIR is a company that rents air compressors and desiccant dryers to industry throughout the UK and beyond. Its fleet encompasses diesel powered sets, zero emission electric machines and oil free units. GenAir reports it recently received a much coveted Green Apple Award for its ‘All Electric – All Weather’ compressor. The company says its management team has over 140 years’ experience within the air compressor industry and operates one of the largest hire fleets of compressed air systems and desiccant dryers in Europe. GenAir equipment is ideally suited for use throughout the world and it supplies equipment all over Europe, Africa, Asia, and South America. t | 0844 775 0890 e | sales@genair.co.uk ALL WEATHER COMPRESSOR COMPRESSED AIR occurs – after extended periods of operation the vanes become worn. Increased lifespan Using a motor with lubricated air can increase the motor’s lifespan. Deprag Schulz comments that the optimum performance and lifespan is attained with 1-2 drops of oil per 1m ³ air consumption. The quality of the supply air should correspond with ISO 8573-1. Nevertheless, all Basic Line motors can also be operated oil-free. However, an additional loss of power of 10-20% as well as shorter maintenance intervals should be factored in. Due to its operating principle, the air motor is perfect for applications in potentially explosive areas: The depressurisation of compressed air cools any frictional heat generated and thereby eliminates any risk of overheating and ignition of gases. In accordance with directive DIN EN ISO 80079-36:2016, the suitability of air motors for use in highly explosive areas must be proven. Deprag Schulz states that the type examination certificate awarded by an independent test laboratory guarantees the user that the Basic Line series can be used without question in accordance with ATEX II 2G Ex h IIC T4 Gb X and ATEX II 2D Ex h IIIC T130degC Db X. The air motor is suitable for the ‘non-mining’ sector in device category 2. These machines reliably guarantee a high degree of safety and can be used in areas where a highly explosive atmosphere of gases, steams, mists (2G) or dust/air mixtures (2D) intermittently occurs. This corresponds with zone 1 and 21 and also includes zones 2 and 22. If the supply air quality is right, this robust motor can even be used problem-free in dusty environments without any affect to proper functioning. The internal excess pressure prevents the infiltration of dust and dirt. www.deprag.com Long system downtimes due to increasing maintenance works are still an issue in production. However, there are sometimes simple solutions which can significantly reduce maintenance time. For this reason, the engineers at Deprag Schulz GMBH u. Co. developed the Basic Line air vane motor, claimed to have a particularly attractive price-performance ratio. The one of a kind QuickVChange vane exchange system (the V stands for vane) is said to be a major time saver. With just a few quick movements vanes are exchanged ‘problem free’. A lengthy system standstill is eliminated because vane exchange on the service friendly Basic Line air motor takes place in situ on the machine without disassembly. Using an Allen key and tweezer, worn out vanes can be exchanged in next to no time – even by untrained personnel. After loosening the cylinder screws on the rear bearing cover and removing the end, vanes can be replaced quickly and simply. The whole job is competed within a couple of minutes and is therefore even faster than replacing the whole motor in the system. The reduced maintenance of the QuickVChange vane exchange system is not only an advantage over all known motors, it also saves valuable production time. Vane wear results predominantly due to the working principle of the motor: The rotor turning an eccentric cylinder is set in motion. In the rotor slits there are vanes which are pushed outwards against the rotor cylinder wall by centrifugal force. Working chambers are created and sealed against each other. Through the expansion of the compressed air, pressure energy changes into kinetic energy and the motor rotates.
