Pulp and Paper

Our closeness to Lucca, the paper industry district, is very important for our experience in industrial fans (dedusting fans, exhaust fans, shredder fans) to fully satisfy the needs of this industrial sector, which calls for hi-tech manufacturing and processing for paper and cardboard, specific applications and systems with particular focus on energy saving.

Electric motors and fans are used throughout the process, from maceration to the finished product, as well as related processes from water treatment to the processing of chemicals and additives. Considering the high levels of electric power installed, the energy efficiency of the electric motors and fans is of crucial importance. The high quality standard, proven resilience and cutting-edge design criteria improve Your investment in terms of duration and reduction of machine downtime.

Drying and Heat Recovery. These are the main applications for Industrial fans and blowers. Drying is one of the main part of paper production process and the hood plays an important role. High temperature resistance, reliability and mechanical endurance are important requirements for the fans used in this application. In paper production process, the heat recovery system works with the high temperature of the steam. Air-air heat exchanger are often used for this process.

De-dusting and Ventilation. Paper machine production process produce fine dust that pollute the air. A clean and safe working environment is very important for operators. Operative area (machine hall) needs optimal conditions and paper, paperboard and tissue machines require specific conditions to work properly with long life without deposits of dust. Industrial fans and blowers applied in filtration devices contribute to remove the dust and provide the correct ventilation required to control temperature and humidity levels too. It also ensure the protection of machinery, plants facilities and building from corrosion, damage and worsening thanks to a balanced climate.

Shredding Fans. Shredders are the right solution to remove edge stripes after the cut during the continuous paper production process and convey the trims to the pulper or collected and pressed. Different construction features, for many kinds of paper and paperboards, make it a very interesting solution for recycling process.

Chemical Applications. During the papermaking process, some chemical additives can be used for bleaching or as opacifier. Our industrial fans and blowers may be provided in special configuration and produced with the most suitable corrosion-resistant materials.

Explosion Proof Industrial Fans and Blowers may be mandatory because of zone classification (Hazardous Area). In the production plants for paper production or converting some activities may require filtration for dust that may be ignited. Some processes require solvent or chemical solutions. Stiavelli Irio srl industrial fans and WEG electric motors and may be supplied in compliance with ATEX Directive 2014/34/EU.
