Dedicated solutions for the printing and paper industries Venti Oelde

Air is the medium we work with. Research and development, planning and consulting, manufacturing and service, whatever we do, the emphasis is on innovative air technology. Venti Oelde plants and components are used for collecting, handling and filtering of air, vapours, gases, dust and airborne solids. An enthusiastic, experienced and knowledgeable team, numbering 250, ensure that individual customer requirements are implemented under economically expedient aspects. The resulting solutions are innovative, efficient, cost-effective and forward-looking. They are appreciated all over the world and...

The conceptual range of available industrial fans includes high-efficiency fans to handle gas and dust and heavy-duty fans for dust-laden process gas or clean air. These also number specially designed fans to circulate hot gas with a temperature to 1000 °C and high-pressure fans to handle gas, dust-free air, chips and other material. Extraction of welding fumes and vapours and exhaust from baths and of heat produces a good “working climate”. Venti Oelde develops total solutions for workplaces, booths, rooms and workshops of all sizes. In the business segment heating and air-conditioning technology,...

Every industry has its own specific processes which present individual and complex demands on air handling technologies. Air, for instance, is needed in a vast number of applications for manufacturing processes, for cooling, drying, conveying and manipulating, for selecting, cleaning, extracting, removing, recycling and also, of course, for climate control. As a system provider with vast experience in this field, Venti Oelde is more than familiar with the often complex processes and requirements of the printing and paper industries, as well as those of the foil manufacturing and processing segments....

These benefit further if we can apply our specialised expertise at an early stage of the planning process. In this way, we can achieve the best possible performance and efficiency while keeping energy costs at a minimum. This is the reason why Venti Oelde always focuses on overall, integrated system solutions in which the functional interaction of all components is a key feature. At the same time, we do not rely exclusively on existing system components; new and advanced developments guarantee users problem-free operational processes in which appropriate technologies ensure an absolute compatibility...

By continually up-dating and further developing existing air handling and disposal systems, Venti Oelde has gained a reputation as a specialist in the field of gravure, offset and flexographic printing. For this reason we take not only the printing presses into consideration, but also their surroundings. When paper webs or foils are printed, the large quantities of process air required are contaminated with moisture and/or environmentally hazardous solvents. Printing machines generally operate with large volumes of recirculated air in which the pollutants become more and more concentrated. Venti know-how...

Similar to the plug-and-play method used in computers, Venti develops pre-fitted compact units together with the users for printing machines such as for intermediate ink drying and bridge drying in flexo printing machines. The modern system solutions are standardised and extensible by a modular principle. Different heating systems can be easily installed. Electrical control units and monitoring sensors are integrated in the modules and tested before final assembly of the printing machines.

The drying process is not simply the removal of moisture from materials; coating and drying also change the physical and chemical properties of the materials involved. For many years Venti Oelde has been a supplier of drying technologies for the printing and paper segments, as well as for the textiles, chemical, metallurgical and wood processing industries. The products offered range from laboratory equipment to large-scale industrial plants. Solutions with various heat transmission systems are just as much a part of the range as convection and contact dryers, IR and UV radiation dryers and combined...

… decisive for quality and performance

Conveying, treatment, filtering and disposal …

Numerous forms of wastes are created in production facilities. In order to ensure problem-free production, any wastes produced must be removed from the immediate vicinity of running machines. Venti Oelde ensures clean and safe working environments by the removal, conveying and disposal of: • Exhaust air with concentrations of hydrocarbons, heat and moisture • Fine dust particles from production abrasion that represent a respiratory hazard, adversely affect machine control systems and mechanical components and can frequently lead to impaired products • Endless strips of edge trim resulting from...

The material is conveyed by an impeller, specially formed for shredding, through an optimized ductwork to the filter or to a container. In order to achieve safe and trouble-free transport and handling of the different waste, it is necessary to reduce the edge trims, cutoffs and discards to small pieces before and during conveying. We employ various methods depending on the given situation. With tearing fans and pipe-mounted cutters we shred continuous product, such as edge trims. The selection and design of the machine is determined by the width of the edge trims, unwinding speed, type and thickness...

In particular, the complex subject of dedusting is an important field of action. Large quantities of microfine dust are produced around extremely fast-running machines. This contaminates the inhaled air and creates deposits which can result in substantial quality loss or interruptions during production. Dust must therefore be captured at its point of origin and guided to suitable filters. This applies to dust produced on winders, on the longitudinal and transverse cutters, on rotary die cutters and vertical punches and also to edge trim disposal. Only effective dust extraction can create the necessary...
