PAC & MAC
Process air control
The control of process air plays a major role in many areas of industry, due to the high potential for energy efficiency and process stabilization. Our PAC control unit (Process Airflow Control) can be adapted flexibly to any production type. The MAC (Maker Airflow Control) was developed specially for the tobacco industry, however. Both systems minimize fluctuations and turbulence in the extraction systems by reducing and homogenizing the necessary air volume or negative pressure. Settings can be adjusted automatically via hand flaps, to ensure optimal flap position. Our control units are available for volume flows from 180 to 7,000 m³/h.
Advantages of a PAC
- Consistent process conditions
- Yield improvement through lower reject rates
- Feasibility of various production states
- Notification of the current process status
- Two possible operating modes to control negative pressure in the piping
- Airflow control through step controlled flap
- Reduction in energy consumption by up to 40% with the combination of integrated VSD on the dedusting fan
- Simple operation and maintenance
Advantages of a MAC
- Rod homogeneity
- Higher material efficiency and tobacco yield
- Reduction in waste, degradation, fine particles and dust
- Lower reject rates on the manufacturing machine
- Better cigarette firmness
- Integrated control with user-friendly touch panel for visualization and parameterization with option to connect to existing SACU tobtronic® touch panel
Markets
- Tire / Rubber
Riedel Filtertechnik offers a wide range of standardized and individual solutions for process exhaust in tire production - from dust extraction to the reduction of odour emissions. With our specifically designed dust extraction systems, we fall well below the limit values of 10 mg/m³. The typical rubber odour? Eliminated by our COPLAS clean system in an energy-efficient and reliable way - making tire production more sustainable than with conventional technologies.
- Tobacco
We have been an innovative partner to the tobacco industry for over 50 years. As a system supplier of exhaust air cleaning and odour reduction systems, we are established worldwide in the field of cigarette manufacturing. With our pneumatic transport systems, central vacuum cleaning systems and machine cleaning systems, we pursue our main goals: Environmental protection, energy efficiency and increasing the tobacco yield in the tobacco industry. We improve the Primary and Secondary sectors with effective and patented technologies.
- Sugar
For decades, we have been an established partner of the global sugar industry for dedusting as well as for sugar conditioning. Thanks to our profound process knowledge, we are more than just an equipment supplier for many of our customers. As a process solution partner, we develop individual concepts together with our customers - perfectly matched to the respective requirements and circumstances.
- Food
Cereals, oil or milk powder - food production is characterized solely by the variety of food products. Numerous process steps, such as extrusion, drying, cooling or product packaging, are run through for their production. The result: dust or strong-smelling odor emissions that are inevitably released into the environment and are subject to strict limits. In order to be able to comply with these, we offer a wide range of products in the field of dust removal through to the reduction of odour emissions.
- Pet food
There are numerous process steps in the production of pet food - be it extrusion, drying, cooling, machine extraction or even the cooking process for wet food. During the processing of wet and dry pet food, dusts and odorous substances are released into the exhaust air, which can strongly pollute the environment. Riedel Filtertechnik offers a wide product portfolio with individual solutions for pet food production. From dust extraction and dedusting of conveyors, extruders as well as dryers to the reduction of odour emissions, everything is covered.
- Compound feed
In compound feed production, odour-intensive substances are often added depending on the recipe. As a consequence, odour emissions are produced which can pollute the environment. The grinding of fine, dry ingredients and the pelleting process also generate dust emissions, which we control with our filter systems. To reduce odours, we use our COPLAS clean technology, which uses neither water nor chemicals for sustainable production and generates no waste products.
