Robuschi provides a wide range of technologies, such as rotary lobe blowers, screw compressors, vacuum for many processes in general manufacturing: central vacuum systems, pneumatic conveying, lifting system, air knives, fluid transfer, industrial cleaning, glass forming, drying and more.
Air carpet
Under vessel air blowing by means of rotary lobe blowers or screw blowers reduce friction between vessel and water during heading / cruising.
Air knives
Air from rotary lobe blowers or blowers is pumped to injectors for priming air knives used to spread coatings on metal coils in steel factories.
Air lifting
Carton panels, wood panels, products packed in bags can be handled by means of suction cups to which vacuum is provided by rotary lobe blowers.
Feeding inert gas
Rotary lobe blowers are used to feed inert gas into oil / gas tanks on vessels, in order to prevent explosion conditions.
Gas handling
Rotary lobe blowers are used for hydrocarbon recovery.
Holding and lifting
To ensure safe processing, work pieces are automatically clamped to the processing table by means of suction heads. A stable and constant minimum vacuum must be generated to ensure that work pieces are held securely in place during mechanical processing.
Industrial cleaning
Rotary lobe blowers are used in industrial vacuum cleaning equipments of medium/large size in order to provide vacuum.
Jet dryer
In coil drying air is supplied through rotary lobe blowers.
Lifting system
Liquid ring vacuum pumps and rotary lobe blowers are used for handling and lifting different materials.
Metalization
Blowers in vacuum booster configuration are used in combination with a primary pump in order to create high vacuum in metalic coating equipments.
Pneumatic conveying
In the pioneering age of pneumatic conveyance, demand was largely for transporting food stuffs such as grain and flour. Today, such installations are constructed for a wide variety of uses, such as transporting goods in dust particle form (flour, cement), solid bulk (pneumatic tube conveying systems) and mixed goods.
Preservation
Before or after processing, wood must be protected against the destructive effects of environmental influences such as heat, moisture, insects and micro-organisms. The practice of soaking the wood in a preservative solution is widespread, but has the disadvantage that the liquid penetrates only a few millimetres into the wood. Complete protection is possible, however, if the wood is degassed and dried with the aid of a vacuum pump. The preservative agent then penetrates much deeper and optimizes the protective effect.
Vacuum in glass forming
Large volumes of compressed air and vacuum are required in the manufacturing of hollow glassware.
Wood drying
The use of vacuum dryers in conventional wood drying chambers can reduce a typical drying time from several weeks to a mere 3 to 4 days. During the drying process, pressure in the chamber is gradually reduced to the minimum. The chamber is pressurized with steam and the air is extracted to prevent cracks and colour changes in the wood that can be caused by too high an oxygen content. Rotary lobe blowers circulate the steam and convey the heat to the wood. Further steam condensate will be exhausted from the drying chamber.
