Renner has launched its new Scroll-line range of compressors, claimed to offer pure oil-free compressed air. The company reports that this new offering is not only applicable for use in the medical and dental technology; an increased demand for oil-free compressed air is also required in, for example, clean room technology, breweries, water purification and process engineering. Renner adds that an increasing number of users are favouring equipment without lubrication and points out that it has been investing in the development of this type of technology for a number of years – the water injected compressor series RSW up to 90 kW, for example.
