Efficient Technologies for Sewage Management and Dry-Bulk Transport
CVS engineering GmbH, based in Rheinfelden, develops advanced and sustainable technologies for a wide range of industrial applications. The company’s portfolio spans high-performance VacuStar vacuum pumps for sewage and industrial waste handling as well as oil-free SKL screw compressors for dry-bulk unloading. “Our Dry Bulk solutions ensure fast, efficient, and residue-free unloading of silo vehicles - ideal for materials such as cement, grain, or plastic pellets,” says Fabio Geiger, Area Sales and Marketing Manager at CVS engineering.
Powerful Vacuum Technology Built for Demanding Conditions
All CVS systems are designed to deliver strong suction performance and long service life, even under extreme operating conditions such as sewer cleaning, sludge extraction, or industrial maintenance. The product range includes oil-free screw compressors (SKL 700, 1100, 1500), rotary vane vacuum pumps (VacuStar L / W), and liquid ring pumps (VacuStar WR).
Complementary drive components and a wide selection of accessories round off the offering.
Versatile Applications Across Multiple Industries
CVS solutions are used by vehicle manufacturers, fleet operators, and engineering firms in the transport, logistics, and road haulage sectors. Suction and jetting vehicles equipped with CVS technology are essential tools in wastewater management, industrial cleaning, construction, and environmental services. “They play a key role in sewer maintenance, emergency cleanup operations, hazardous liquid waste transport, and in the rapid unloading of bulk materials across the construction and food industries,” Geiger explains.
Growing Demand Driven by Urbanization and Environmental Regulations
Urban growth, stricter sustainability requirements, and evolving regulations - such as decarbonization measures and noise-emission limits - are increasing the need for efficient waste-handling infrastructure and low-emission transport solutions. CVS engineering’s technologies support customers in meeting these rising demands.
Clean Air, Low Wear, and Efficient Operation
The oil-free SKL compressor series ensures clean conveying air - a critical factor for sensitive sectors like food processing and chemical production. Additional benefits include low weight, reduced discharge temperatures, and a broad speed range for energy-efficient performance. The VacuStar series further enhances durability with optional plasma-nitrided or ceramic-coated components, while innovative cell-ventilation systems enable continuous operation at high vacuum levels without overheating.
A Complete Technology and Service Partner
CVS engineering supports both OEMs integrating components into vehicle systems and end-users such as freight operators and municipalities. The company places particular emphasis on low weight, high reliability, cost-efficient operation, and strong service support - delivering complete solutions from a single source.
