PVC dust monitoring for early warning of hazardous dust concentrations
With AirSafe 2 sensors ENVEA has realised continuous dust monitoring to give early warning of potentially hazardous dust concentrations in packaging areas. At a PVC powder manufacturing site, robots are used in the packaging plant to fill 25 kg bags. The company’s ATEX guidelines state that there is an ATEX Zone 22 in the area of 5 metres around the plant. The ignitable mixture of PVC powder is 50 g/m3, which can happen if a bag does not withstand the pressure and breaks when being filled by a robot. However, by the time the system recognises this and internally switches off the filling, several kilos of material have often escaped into the ambient air, resulting in a potentially explosive atmosphere [> 50 g/m3]. Process data * Customer: Manufacturer of PVC powder * Material: PVC powder * Installation: In the packaging plant * Function: Dust monitoring to give early warning of potentially hazardous dust concentrations Solution In the application described, two AirSafe 2 sensors were used for continuous monitoring of the ambient air. In this case, a unit suitable for use in ATEX Zone 22 was used. The two

Non-stop clean innovation Transfer points now spillage- and dust free
Non-stop clean innovation
Transfer points now spillage- and dust free With the innovative AirScrape seal skirting, spills and dust at transfer points in conveyor systems and belt damage are a thing of the past. In the minerals and mining industry, contamination of conveyor systems and dust generation during operation are a well-known problem. Conventional conveyor skirting at belt transfer points can help here, but even friction forces quickly wear them out; they lose their effect and also damage the belt of the conveyor during long-term use. This in turn increases the costs for maintenance or replacement. The AirScrape from ScrapeTec Trading Ltd. is quite different. It represents one of the rare innovations in this industrial sector, is virtually maintenance-free, increases the service life of conveyor belts and permanently saves cleaning efforts. Beyond the chute and conveyor belt, the AirScrape ensures more cleanliness. AirScrape. The operating principle is in the name If you see the AirScrape side seal in use, you can quickly

Dust Emission below 5 mg/Nm³ with Airtechnic Multi-Cyclones
Dust Emission below 5 mg/Nm³ with Airtechnic Multi-Cyclones
Recently Airtechnic Solutions from The Netherlands has completed two multi-cyclone systems of which the dust emission, without back filter, is less than 5 mg/Nm3. Thus fulfilling local requirements for dust emission. In the course of years Airtechnic has further developed cyclone technology up to the point that with cyclones and multi-cyclones very low emission rates can be achieved, even at very high dust loads. Opposed to alternative dust extraction methods, the main advantages of (multi-)cyclones are that a much wider array of dust types can be handled, no more costly filter exchanges and a constant differential pressure across the entire system during operation. Also for variable flow rates Airtechnic supplies cyclone systems with a guaranteed emission. The fully automated process control system ensures that our robust dust extraction systems are user-friendly, reliable and safe.

Micron Cleaning Station
Micron Cleaning Station
The Micron Cleaning Station is a unique cleaning system and will add a new dimension to the concept of cleaning. Designed by industrial air technical engineers it can handle the toughest cleaning jobs with ease. Especially in the recycling industry where a lot of dust is created due to demolishing and de- assembly operations. Suction By using a unique 3-stage separation this system is suitable for picking up pieces of coarse components such as vegetables, chips, small metals, liquids and particulate matter up to 1 micron, without immediately blockage of the filter. This a constant and strong suction power all the time. Blowing Beside suction cleaning, this system can be turned in a second into a powerful blower. With our special lance blowing speeds of 300 km per hour can be achieved. This is similar as blowing a compressed air pistol, only more powerful by a multitude of air volume. With the Micron Cleaning Station you can first blow-off dust and pieces

Brabender improves accuracy in feeding High reliability in feeding, less rejections.
Brabender improves accuracy in feeding
High reliability in feeding, less rejections. Higher demands of product quality in the chemicals, detergents, food and plastics industries needs higher dosing accuracy. Besides the accuracy of loadcell and feedcontroller as well as a proper selection of feedertype, the final accuracy also rely on a proper ventilation and refilling of the feeder. Deaeration while feeding of powders by using filtercandle or filterhose leads to blockage after a short time. The air escapes through inlet and outlet of the feeder resulting in a delay of refilltime and an uncontrolled blow-out at the outlet leading to rejection of production by an inaccurate dosing, unreliable production and various errors. Based on more than 50 years experience in developing, manufacturing, installation and service, Brabender Technologie KG developed the JetFilter, an improved self-cleaning system for venting of gravimetric feeders. The JetFilter works as dust collector for particles larger than 5ìm and is mounted on the feeder. Compressed air
