These technologies ensure maximum suction capacity and durability in extreme conditions – such as sewer cleaning and sludge extraction. The range includes oil-free screw compressors (SKL 700, 1100, 1500), rotary vane vacuum pumps (VacuStar L / W) and liquid ring pumps (VacuStar WR) – supplemented by drive components such as hydraulic adaptors or drive shaft couplings and other accessories.
Sewer maintenance, efficient unloading of large volumes of material
These solutions are in demand among fleet operators, vehicle manufacturers and engineers in the road haulage, transport, distribution and logistics sectors. The suction and flushing vehicles are used in the wastewater sector, in industrial cleaning (grease separators in the catering industry), the construction industry (pit emptying), agriculture and in environmental technology for the removal of pollutants. “Specifically, they are indispensable for sewer maintenance, emergency cleaning in the event of blockages, the transport of hazardous liquid waste, and the efficient unloading of large quantities of material in the building materials and food industries,” explains Fabio Geiger.
A growing need for efficient waste management and low-emission transport
“Particularly against the backdrop of urbanisation and increasing environmental regulations driven by decarbonisation and noise protection, there is currently a growing need for efficient waste management infrastructure and low-emission transport solutions,” emphasises Fabio Geiger.
Clean conveying air is essential for the food and chemical industries
It is not least these challenges that make CVS engineering’s technologies the ideal solution: the oil-free SKL technologies ensure clean conveying air – a fundamental requirement of the food and chemical industries. Further benefits of the ‘Dry Bulk’ compressors include their low weight, low discharge temperatures and wide speed range, ensuring energy-efficient, resource-saving operation. The VacuStar series for ‘sewage handling’ offers users high protection against wear and corrosion thanks to optional plasma nitriding and ceramic coating. “Innovative cell aeration systems also enable continuous operation at high vacuum without overheating,” adds Fabio Geiger.
Complemented by first-class service
With this package, the Rheinfelden-based company serves OEMs (Original Equipment Manufacturers) that install components ex-works, as well as end customers such as haulage firms and local authorities, who place great importance on weight, reliability and low lifecycle costs, as well as first-class service.
