Filter technology

We offer efficient dust collectors and filters featuring state-of-the-art-technology for all purposes. Series production of our components and modular design provided by our suppliers enable tailor-made solutions for industrial dedusting. Besides dust collection, measures to prevent dust explosions are taken as well. Filters can be provided as cartridge, bag, bin-top or insertion filters.Filter technology

Silo monitoring, fill monitoring

We offer limit switches for filling level measurement (full, empty or demand). We recommend using vibration or rotating paddle level limit switches. For continous measuring silopilots, ultra sonic or radar sensors and microwaves are used. Data detected by the sensors can be graphically visualised, saved into databases or forwarded by email.Silo monitoring, fill monitoring

Vibration bottoms and hoppers

Vibration bottoms and hoppers are used for discharging non-free-flowing bulk goods and can be delivered for any industry. The hoppers or vibration bottoms are fixed around the silo outlet at several locations. There they are moved in horizontal oscillation by one or more unbalanced motors. The vibrations are propagated on the product column in the silo cone therefore loosening the stored material which can then be discharged more easily from the silo.Vibration bottoms and hoppers

Telescope chutes

By using telescope chutes the filling procedures can be drastically accelerated. Additionally telescope chutes offer the possibility of a gentler extraction for sensitive bulk goods. For the extraction of high-quality bulk goods, integrated filters can be used to prevent product segregation. Suctioned fine material is immediately re-fed into the bulk good.Get further

Shut-off valves and fittings, sliding valves

To protect your silo from overpressure or negative pressure P+W Metallbau offers you a broad range of pressure balance valves. Whether regulating gate, metering gate or slide-gate valves - we have the right product for your application. We deliver pneumatic as well as power and manually operated gate valves. Our shut-off valves and fittings product range also contains different ball valves, squeezing valves, butterfly valves and gate valves.Get further

Air dryers, dehumidifiers

Outdoor silos are often exposed to broad temperature fluctuations which result in the formation of condensation inside the silo. Air dryers counteract this, therefore effectively helping to protect sensitive bulk goods. Our air dryers are mounted inside the silo skirt. They are either continually providing dry air for your silo or based on temperature monitoring.Get further
