KREISEL Umwelttechnik – Innovation by tradition

We are an international plant manufacturer and specialist with many years of experience in handling bulk materials
of all types and for removing dust from processes. By ambitiously advancing our products, we consistently focus on
the needs of our customers and make a committed contribution to saving resources.



    The KREISEL DOME VALVE® is a pilot-controlled safety valve. It is used at counter pressures being higher than those for standard valves. Thus they have a positive influence on the planned operating pressure and the system design. The KREISEL DOME VALVE® as a gas-tight isolation valve in pressure vessels was developed in Krauschwitz. The benefits arise from the cross-section being available to 100% in the opening condition. When opening or closing the dome valve, any relative motion between calotte, dome and pneumatically controlled sealing is exlcuded. The sealing is inflated by means of control air and pressed to the dome. Particles of bulk material smaller than 2mm are effectively retained. The KREISEL Dome valve tightly seals against high differential pressures.

  • Pneumatic Conveyance from KREISEL

    KREISEL pneumatic conveyor systems deliver bulk materials of all kinds. Conveyor distances over 1,000 m and conveying rates of more than 100 t/h can be implemented. All conveyor systems are customised and energy-optimised. Rotary feeders, pressure vessels, jet conveyors or screw valves are used as feed-in units. KREISEL filtration systems separate the material at the reception point.

  • Cyclone Separators

    Cyclone separators according to the KREISEL standard are characterised by their simple structure, low energy requirements and great reliability. They are suitable for use in all industry sectors. The separators can be used individually, in batteries or combined with other dust separators. They can also be used as pre-separators or as spark guards. Components of the cyclone separators:
    -Rotation-symmetrical upper section with inlet spiral and immersion tube
    -Conical lower section
    -Dust funnel with connection for dust removal units
    -Gas outlet for removal of the purified gas

  • Filter Systems

    KREISEL filter systems separate the bulk material dispersed by the conveyed medium in the conveying process. They ensure that the emissions remain far below the limits. Depending on the application and space available JET bag filters can be used as collecting or bunker-mounted filters. As a result of the modular design of the filters up to 200,000 cubic metres of air can be cleaned for dust removal each hour.

  • Recuperators/heat exchangers

    KREISEL recuperators pick up waste heat from production,
    return it to the process in a circuit or for other energy uses. The specially-developed type K radiation recuperators generate optimal high combustion air temperatures and reduce fuel consumption significantly. Designed and built for the respective application, they are primarily used in the Glass industry for recuperative heated glass melting furnaces, Ceramics industry, Metallurgy and in other Energy-intensive industrial sectors.

  • Pressure Vessels

    KREISEL pressure vessels allow maximum charging of the transport gas with the conveyed product at lowest transport speeds.

    KREISEL pressurised gas transport means
    -Gentle transport of the conveyed product
    -Low pipe wear
    -High availability of the conveyor system
    -Minimal energy requirements
    -Low maintenance

    Manufacturing range
    -SingleFeed (Single pressure vessel systems)
    -TwinFeed (Twin pressure vessel systems)
    -DoubleFeed (Two-storey pressure vessel systems)

    KREISEL is a TÜV-approved manufacturer of technical welded products for container construction in accordance with AD 2000 Leaflet HP0.

  • Double Flap Gates

    KREISEL double flap gates are used for continuous delivery of flowing, dust-based, granular and coarse bulk materials – while simultaneously sealing process and vacuum chambers.

  • Slide gates

    KREISEL slide gates are used as locking, metering and safety components in process engineering systems in all industry sectors.

  • Two-way distributors

    KREISEL two-way distributors are used to direct the flow of bulk material optimally.

  • Rotary Valves

    KREISEL rotary valves are produced in a wide range of versions
    for theoretical volume flows of up to 2,700 cubic metres per hour. They have proven themselves for many years in process engineering systems for environmental and bulk material technology in many sectors. Rotary feeders are used to deliver bulk materials with constant volume flow rates from containers to connected system components or conveyor systems, and for metering. For example, they are used under filters and cyclones, to extract bulk materials from air conveying circuits with minimal pressure loss. Via mixers, dryers and mills, they are used for volumetric metered feed of the bulk material in continuous mixing and processing processes with an air seal, and also as a thermal shield.

    Special designs
    Blow-through rotary valves
    Cutter feeders
    Self-cleaning rotary valves
    Tangential rotary valves

  • Ceramic Rotary Valves

    KREISEL wear-resistant ceramic rotary valves are characterised by high performance, high throughput and increases in service life by
    a factor of 10 to 20 compared with steel valves depending on the material to be conveyed.

    KREISEL ceramic rotary feeders have a
    high availability, cause
    lower maintenance costs and
    lead to significant cost savings.

  • A Clean Solution for Bulk Materials: KREISEL at easyFairs Dortmund 2018

    The family-owned company KREISEL GmbH & Co. KG from Krauschwitz in Saxony will be on presentation in Hall 5, Stand H02-5 of the “easyFairs SOLIDS” trade exhibition from November 7th through November 8th in Dortmund. Already for the eighth time the specialist for bulk material and dosing technology will be an exhibitor of both proven and new technologies. The KREISEL Group with business locations in Krauschwitz, Hamburg, Thierhaupten/Augsburg and Blankenburg/Harz will present itself as an international plant construction company. The staff at KREISEL are experts in the specialized field of bulk materials handling. Customized conveyor systems – from storage bins to pneumatic conveyor systems, all the way through to dust removal plants – everything you need is provided from a single source. We plan, design, manufacture and supply plant components in accordance with your performance parameters and technical requirements. The KREISEL service team mounts the assemblies at the place of destination, including final commissioning and the seal: Made in Germany. “When it comes to sales SOLIDS is a compact trade exhibition in our strongest product segment,” comments KREISEL managing director Wolfram Kreisel. “This is where we meet new and old customers from the relevant industries – for example, food, chemicals, pharmaceuticals, plastics, recycling and metalworking as well as the mining industry.”
    With a height of 4.10 meters the largest rotary feeder offered by KREISEL would be more than the exhibition stand could handle. Thus professional trade exhibition visitors can expect to see more manageable units.
    With the aim of constantly developing and improving our products on the one hand, and optimum solutions for problematic bulk materials on the other, a pilot plant was commissioned on the company premises of KREISEL GmbH & Co. KG in year 2013. The TECHNICAL COLLEGE consists of all of the pneumatic conveyor plant components and measuring facilities. We at KREISEL underscore the high quality claim of our research work and thus ensure a reliable academic standard for external tests at this facility. A testing laboratory rounds out the TECHNICAL COLLEGE and puts you in a position to test and optimize your conveying options prior to design and commissioning of the respective conveyor plant. Apart from its proven component business KREISEL is now moving into plant construction. When it comes to sales, planning, design, project handling and the commissioning of conveyor plants, the Krauschwitz company has decidedly strengthened its position with the establishment of KREISEL GmbH in Hamburg. Our KREISEL subsidiary in Hamburg completes the assemblies from our production line for your special application when it comes to pneumatic or mechanical conveyor systems. Our staff assemble the operable plants at the place of destination ( “easyFairs SOLIDS” offers perfect opportunities to learn about the enhanced performance of KREISEL, a company with a tradition of more than one hundred years (
