COMPRESSED AIR 38 HYDRAULICS & PNEUMATICS October 2022 www.hpmag.co.uk higher flow performance, reliability and lower lifecycle cost. By using biodegradable HVO instead of traditional diesel, customers can reduce their CO2 emissions and particulate matter pollution from the engine by even 90%, without impact on performance nor any engine modifications or changes in service intervals. In addition to running on HVO, the compressors can also run with mixed fuels including regular diesel. Performance, reliability and sustainability Alex Persyn, director of product management at Rotair SpA, comments: “At Rotair, we pride ourselves on Rotair SPA has approved the use of EN15940-compliant hydrotreated vegetable oils, or HVOs, as a fossil-free and more sustainable alternative to power its portable compressors. The HVO fuel can be used with all the models in the Rotair MDVN Eco5 and MDVS Eco5 portfolio featuring Kohler engines compliant with the EU Non-Road Mobile Machinery (NRMM) Stage V emission standards. The MDVN and MDVS portable compressors, designed for standard applications but also with sandblasting, fibre optic cable laying and other applications requiring cool, dry air in mind, address customers’ needs for Rotair approves HVO, fossil-free diesel fuel for its portable compressors delivering customer flexibility and convenience while continuing to deliver the best product options that meet their needs for performance, reliability and sustainability. Meeting critical sustainability challenges, including the reduction in emissions and improvement in air quality, are common objectives as we seek to combat climate change. The validated use of HVO in our units gives our customers more options for improving the sustainability of their operations while maintaining compressor performance and efficiency – a win-win solution.” HVO is a renewable paraffinic fuel also known under the names ‘synthetic diesel’ and ‘renewable diesel’. It is produced with plant or animal oils derived from the residues of the meat and fish industries. Since it is obtained from organic material, HVO – unlike biodiesel – does not use agricultural resources nor does it contribute to deforestation. Pneumatic control system The HVO-compatible MDVN and MDVS units come in standard version or with integrated after-cooler and condensate filtration. The units feature a pneumatic control system to save fuel consumption by automatically adjusting engine revs to the amount of air needed. Offering a wide range of pressures, including Dual Pressure, the units also feature an intelligent start/stop system that provides a regulated build-up of engine revolutions and pressure, improving durability. Rotair’s portable compressors are also known for their compact dimensions for improved manoeuvrability and an optimal dimension to power ratio. The units have European homologation for road circulation with brakes. www.rotairspa.com
