Industrial Filters and Stainless Steel Filters

Catalyst Support Screens

Dorstener Wire Tech produces a wide range of catalyst support screens and grids for the petrochemical and refining industries. Wire mesh support screens allow for more open area and more precise openings than perforated steel or wedge wire screens. As a result, catalyst support screens manufactured using wire mesh are more efficient.

Micro Mesh Parts

Dorstener Wire Tech manufactures custom miniature mesh parts that are used in miniature valves, condensers, and electronic assemblies. We specialize in the design and manufacture of custom wire cloth and mesh, and offer fabrication, stamping and finishing services to provide production-ready miniature wire cloth elements. Soft sintered, annealed and diffusion bonded cloth are available for applications that require precise shaping, flexibility during processing and part stability.

Sand Screens and Filter Elements

DWT has supplied wire cloth and drainage screen products for the oil and gas industry for more than 15 years. Today we offer a wide range of filtration and drainage screen cartridges. Our traceability and quality system ensures you receive the proper documentation with your wire sand screens, sand screen mesh, and custom wire mesh filtration products each and every order.

Hot Gas Filtration Elements

Dorstener Wire Tech produces a wide range of woven wire mesh and welded wire products ideally suited for hot gas filtration applications.

Just like their fossil fuel cousins, alternative fuels need filtration. Many of these fuels require high temperature processing, resulting in the necessity for special metals, media, and finishing to handle the harsh processing environment. DWT has the expertise and products to manufacture wire filtering products for this new demanding market.

Common applications in this new market include wire cloth filter elements for biofuel processing and power generation, spark arresting screens, catalyst recovery media, heat diffusers, and cleaning filters for gases released during chemical processing.

Extruder Screens

High quality filtration requires high quality media. Polymer manufacturing requires a wide range of filters and filter media for processing, finishing and recycling the materials. Dorstener Wire Tech has over 15 years’ experience in manufacturing and engineering of polymer filtration components of many varieties to meet the challenges faced by today’s polymer processing industry. Dorstener Wire Tech is a fully integrated company that not only produces polymer filters and extruder screens, we produce the media we use in our filters. All of our polymer filtration media is designed for the specific requirements of the users processes. Our state of the art manufacturing facilities allow us to offer high performance filters direct from the manufacturer at an economical cost.

Polymer Filtration

The plastics and polymer industry requires many different industrial filters to ensure a clean melt stream. Our metal filter screens are engineered to fit all styles and types of melt pumps and screen changers. The end goal of our product is to guarantee the final quality of your product.

The most common screen changers for melt filtration use single or multilayer wire cloth extruder screens. We produce these in round discs, rectangular or kidney shaped screens. The construction of the screen pack is critical to process performance and final product quality. Mesh combinations are carefully chosen to achieve a high strength pack that provides desired filtration levels and optimal throughput. To assist in the production of sensitive or high value polymers we offer frame pack screens for superior sealing and control.

Stainless Steel Air Filtration

Dorstener Wire Tech can supply air filtration and cooling tower panels with a newly designed filter media. Stainless steel wire mesh in the air filtration industry is not only found in the hot gas sector, but it can also be used for the filtration of pollen, fibers, insects and other impurities upstream of air-cooled units. We have introduced our air sieve as a protective filter to the market.

Fine cloths with a large air-flow, reinforced by our sandwich construction, allow a great, robust filtration surface that is corrosion-resistant and can be cleaned easily.

Extruder Screens for Food Contact Polymer Filtration

Are you producing food contact polymers for beverage containers or do you produce packaging contact film for food? Since food grade materials must adhere to a variety of regulatory requirements, your filtration parameters and expectations should be just as stringent. Dorstener Wire Tech can engineer a filtration component that will ensure all of your concerns are eased.

Dorstener Wire Tech can ensure that your parts are ultrasonically cleaned to provide a peace of mind that your food contact materials are being filtered through filter media that is free of dirt, oil and grease. Ultrasonic cleaning is available for all parts in stainless steel and carbon steel alloys.

Injection Molding Wire Mesh

More and more injection molding companies are switching to Dorstener Wire Tech’s high quality mesh in order to offer their customers with the highest quality of injection molded filters. This is no surprise given DWT’s 60+ years of combined experience in creating mesh that exceeds most industry standards and should be the only mesh used by your injection molding provider.
