GARDNER DENVER HAS launched a new, premium range of oil-lubricated screw compressors as part of the CompAir L-Series, which offer best-in-class efficiency. The premium range, available in 90 kW, 110kW and 132kW models, combines a fixed speed compressor with IE4 motors. This creates a system that delivers energy efficiency improvements of 2.3 per cent when compared with standard models. With businesses around the world striving to implement increasingly sustainable strategies and equipment in order to reduce the environmental impact of their operations, the new premium range can help offer businesses a long-lasting and energy-efficient investment, says the company. The new models feature a newly patented oil regulation valve, which automatically regulates oil injections and discharge temperature according to environmental conditions. This reduces power consumption as well as eliminating the risk of condensate and corrosion in the system. It also helps maintain the oil’s high quality throughout the compressor’s lifetime, reducing the unit’s total cost of ownership. The premium models include an improved airend, designed and manufactured at Gardner Denver’s Centre of Excellence in Simmern, Germany. It is supported by the CompAir Assure warranty, which covers the airend for up to 10 years or 44,000 hours. The airend is the heart of the compressor, and the improved technology from Gardner Denver features a larger-sized inlet and outlet to help improve air flow and reduce pressure drop. As Industry 4.0 drives the need for users to share an analyse asset data, businesses are demanding more intelligent insights from compressed air performance to remove risks, improve productivity and reduce energy consumption. The premium range supports iConn, Gardher Denver’s digital analytics platform for helping manage and optimise

compressed air usage, as well as a user-friedly touch-screen control system that provides a range of insightful monitoring capabilities. Dora Artemiadi, product manager for Industrial Compressors EMEA at Gardner Denver, said, “As a leader in the compressed air industry, we are committed to bringing the latest compressor innovations to the market, which deliver reliable and consistent compressed air that operators can depend on. Our new screw compressors are just the latest example, helping to improve energy efficiency and reduce a system’s whole life costs.” She added that compared with competitor models, one of the premium units delivered five per cent greater energy effciency and up to 12 per cent higher flow rate, providing energy savings of Euro 3,700.
“Capable of delivering pressure ranges from 7.5 to 10 bar and volume flow between 15.5 to 24.8 m3/minute, our new models have been designed so that servicing is a simple and straightforward process too. Easy access to parts that need replacing, such as filters and separators, helps ensure maintenance is a hassle-free process. “The premium models also feature many high-quality details that help set it apart from others models available on the market, including Victaulic couplings and an automatic lubrication system for the motor’s bearings, which prevents drive failure due to improper or poor lubication.”

Reciprocating compressor valve failure: diagnose, repair, prevent RECIPROCATING COMPRESSOR VALVE failure can cause system lags and affect the seamless operation of processes. Compressor valve parts manufacturer KB Delta offers advice on diagnosing, repairing and preventing compressor valve failure in a blog on its website. The main causes of reciprocating compressor valve failure are environment and mechanical factors, it says. Environmental factors can include improper lubrication, corrosive contaminants and foreign material. Reciprocating compressors need to be operated in a conducive environment where the machine is not exposed to dirt and air-bound oil and mist. As for mechanical factors, system overload or

overheating can cause high levels of stress on the valve, and incorrect use of the compressor may also lead to a breakdown of the valve. Mechanical causes of compressor valve failure include spring failure, high-cycle fatigue and off-design operation. Common signs of reciprocating valve failure include overly high suction pressures, low discharge pressure, overly high discharge temperature, and working more quietly than usual. Troubleshooting will enable you to repair reciprocating compressure valve failure. The blog provides advice on how to do this. To prevent valve failure in the future, you should examine line temperatures; check for low compressor amp draw, which will indicate there may be performance issues with your
valve; check the compressor shell for overheating; and examine the valve bypass when the compressor is off. “Reciprocating compressor valve failure is easy to diagose, repair and prevent if you’re informed on how best to go about each of these,” says KB Delta. “Once your valves are in order, their long life span will be assured, instead of being tampered with by environmental and mechanical factors. The best part is, you can prevent these problems from occurring in the future, and therefore, reduce the frequency of maintenance on your reciprocating compressor.”
