Gardner Denver is presenting a wide range of technical solutions for generating pressure and vacuums at the IFAT 2016. With an impressive variety of versions, the company is responding to the trend for increasingly smaller batch sizes and to the varied demand for sophisticated energy-saving pumps and compressor technology for stationary and mobile use (Hall A3.237/336 and Hall B5.301).
Gardner Denver possesses a vast amount of expertise in fundamental environmental technology with famous global brands CompAir, Elmo Rietschle, Robuschi and Wittig. Internationally, this expertise is put to use in drinking water production, wastewater treatment, sewer cleaning and biogas production as well as recycling waste and reusable materials, with the aim of conserving resources through lower energy use and reducing emissions, with greater efficiency.
Tailor-made products offer great optimisation potential for wastewater treatment plants. The varied Gardner Denver range – which covers low pressure turbo compressors, screw and rotary piston compressors, side channel blowers, rotary vane and claw compressors, and vacuum pumps – provides all the equipment needed to achieve maximum energy efficiency when using different systems in combination.
With a robust construction, low maintenance and a long service life, the Wittig rotary vanes have become widespread components which work around the clock in wastewater treatment plants, in biogas production and in waste disposal applications. The air-cooled rotary vane compressors, which are lubricated with fresh oil, and have volume flows of 120 to 540 m³/h and a positive operating pressure of up to 2.5 bar (g) are ATEX-certified (II 2G c IIB T2) and are used to compress biogas, landfill gas and digester gas, to name just a few examples. As an example of this product group, the L 50 GK type will be on display at the trade fair.
