Case Study: DENA Rotary Filter FIR

The Challenge

The client’s facility faced ongoing issues with dust accumulation and fiber dispersion. These problems compromised product quality and required frequent maintenance. Additionally, the client needed a system capable of integrating with their high-capacity operations, minimizing downtime, and complying with strict environmental safety regulations.

The Solution

DENA developed a rotary filtration system featuring:

• Advanced Filtration Design: A multi-stage design effectively captures fibers and dust particles, improving overall air quality.

• Dynamic Airflow Management: Thanks to the DENASYS control system, fans and motors operate at variable flow rates continuously managed by specific algorithms. These algorithms account for the aeraulic conditions of the chamber and the degree of filter clogging, ensuring constant pressures and volumes for smooth operation across all lines.

• Self-Cleaning Technology: Rotating drums and strategically placed suction nozzles remove particles from the filter media, extending its lifespan and reducing manual interventions.

• Material Handling Options: Depending on operational needs, filtered fibers can either be reintegrated into the production process or collected separately for disposal.

Key Results

The installation of DENA’s rotary filter achieved significant improvements:

• Cleaner Working Environment: Reduced airborne contaminants created a safer and healthier workplace for employees.

• Operational Efficiency: Consolidating filtration activities into a single robust system lowered energy consumption and minimized production interruptions.
• Cost Savings: The extended lifespan of filter components, combined with automatic cleaning features, reduced maintenance expenses and downtime.
• Sustainability: Filtered air is now safely recirculated within the facility, meeting stringent environmental standards and reducing waste.

Client Impact

The client experienced a notable decrease in maintenance interventions, an increase in productivity, and improved air quality. They highlighted the system’s adaptability and efficiency as key factors in achieving their operational goals.
