Applications

Dust adhesion and high wear

Fans used in dedusting are subject to high wear due to particle impact, but they must also prevent dust adhesion as far as possible. We meet this challenge, for example, by specifically selected blade geometries.

Induced draft fans, also in wear-protected designs, are used wherever filters and cyclones are employed, e.g. in the cement, wood and steel industries, in paper production or in power plants.

High lifetimes and low maintenance costs

In contrast to ventilation fans from the air-conditioning and ventilation industry, the focus for fans for process air and cooling is on long bearing service lives combined with the lowest possible maintenance costs. In addition, the aim is to achieve the highest possible overall efficiency of over 85%.

For process air & cooling, fans of various designs are used in a wide range of industrial sectors. The longevity of all components, even in continuous operation, is a particular priority here.

Precise performance even at high temperatures

When sizing fans for extruction, the performance must be very precisely matched to the specifications for air volume and pressure difference in order to achieve optimum results in the process. At the same time, these fans must be protected against both high temperatures and aggressive, toxic, abrasive, erosive or explosive gas mixtures. These fans are mainly used in the chemical industry, the petrochemical industry and also in the pharmaceutical industry.

Temperatures of 450°C and more

When sizing fans for extruction, the performance must be very precisely matched to the specifications for air volume and pressure difference in order to achieve optimum results in the process. At the same time, these fans must be protected against both high temperatures and aggressive, toxic, abrasive, erosive or explosive gas mixtures. These fans are mainly used in the chemical industry, the petrochemical industry and also in the pharmaceutical industry.

Experience for your application

Conveying solids by means of transport fans requires a high level of experience in the mechanical design of all components. In the case of fans for pneumatic transport, the focus is on robust impellers, blockage-free material guidance and vibration-insensitive bearing designs.

Designed for persistent loads

In addition to standard fans, customized installation units are frequently used for air and hot gas circulation. Temperatures of 750° Celsius and more are safely handled.

High speeds and high efficiency

Small air volumes at high pressures require small, compact and high-speed fans with speeds up to 6,000 /min. When designing fans for blast air generation, high efficiency with the lowest possible noise and precise pressure control must be taken into account.

Blast air generation is an important topic, especially in the plastics industry and film production. In addition to the fan, POLLRICH also offers innovative solutions for the complete process air technology.

Explosion-proof according to ATEX and EEx guidelines

Explosion-proof fans are used in a wide range of industrial applications. Corrosive as well as abrasive and toxic gas mixtures can occur individually, but also together. For gas conveying fans, explosion proofing (ATEX and EEx) is made possible by using labyrinth seals and seal gas admission. This ensures safe operation, environmental compatibility and occupational safety.

Robust and reliable

Induced draft fans convey the exhaust gas flows out of the plant and guide them via the downstream filters, separators and scrubbers to the stack or downstream processes. High operational reliability and robustness as well as precise air volume and pressure control are just as essential for fans used for exhaust air and exhaust gas cleaning as high efficiency levels. A typical application is, for example, in waste incineration plants.
