Chemical Industry

In numerous chemical reactions and production steps, the controlled movement of process gases is essential. Centrifugal fans are used to transport gases between different plant components, for example in reactors, distillation columns and drying plants. In this context, precise control of volume flow and pressure is crucial for optimizing chemical processes.

Many chemical processes produce hazardous vapors, gases and dusts that must be safely extracted to protect the health of employees and the environment. Centrifugal fans in industrial exhaust air systems ensure the effective capture and transport of these substances to suitable treatment facilities such as filters, scrubbers or thermal post-combustion systems.

In the chemical industry, drying processes play an important role in the production of solids and powders. Centrifugal fans are used to convey hot air through the industrial drying plants and thus efficiently remove moisture. The precise control of air parameters (temperature, humidity, volume flow) is crucial for product quality and energy consumption.

In certain cases, centrifugal fans are also used for the pneumatic conveying of powdered or granular chemical products. In this process, the material is transported in an air stream, which is a gentle and efficient industrial conveying method.

Centrifugal fans are used in some industrial cooling processes, for example to ventilate industrial cooling units or to support heat dissipation in certain industrial plant components.

In some chemical reactions, the supply of reaction air or oxygen is essential. Centrifugal fans provide the required air flow at the required pressure to support the chemical reaction on an industrial scale.

Many of the pumped gases, vapors and dusts are highly corrosive and can attack conventional materials. This leads to material wear, malfunctions and potential safety risks in industrial plants.

In many areas of the chemical industry, there is a risk of explosive atmospheres forming. The fans used must therefore comply with the relevant ATEX directives and be designed so that they do not represent ignition sources in industrial environments.

The transportation of toxic or hazardous substances requires fans with a high level of tightness to prevent leaks into the industrial environment and to protect both personnel and the environment.

Particles in the gas flows conveyed can cause abrasive wear on the impellers and housing parts, which reduces the service life of the fans and shortens the maintenance intervals in industrial applications.

In some industrial processes, centrifugal fans have to convey gases at high temperatures, which requires special material selection and design features to ensure mechanical strength and functionality.

Servicing fans in chemical plants can be challenging due to the potential hazards of the industrial environment and the complexity of the equipment. Accessibility and the development of efficient maintenance strategies are therefore crucial.

The integration of centrifugal fans into existing and new chemical plants requires careful planning and coordination with other industrial components and control systems.
