The Importance of BESS Lab Certification for Agricultural Fans

Fans for industrial and agricultural purposes are subject to strict requirements and conditions. To address the need for certified and clear performance, the BESS Lab certification has emerged as a benchmark for quality assurance in the world of industrial and agricultural fans.

What is BESS Lab Certification?

BESS Lab, short for “Bioenvironmental and Structural Systems Laboratory,” is a globally recognized research lab at the University of Illinois (USA) that specializes in testing the performance, and energy efficiency of ventilation fans ranging in size from 8” to over 50” in diameter.

This online publication has become a precious database and provides the livestock/poultry housing designer and greenhouse designer an unbiased source of performance data for over 800 commercially available ventilation fans. The fans are searchable according to size, airflow, ventilating efficiency rating and manufacturers, so comparisons can easily be made between producers and models.

How a fan can be certified?

Manufacturers can rent the lab for a day; they bring their fans and prototypes to the lab and do about 10 or 12 tests in a day using the latest technologies available to analyze the performances of air circulation and exhaust fans. At the end of the session, companies can list their test data in “Agricultural Ventilation Fans: Performance and Efficiencies”, the official database of BESS lab.

Importance of BESS Lab Certification for Industrial Fans

  1. Reliability and Performance Assurance: BESS Lab certification provides a “virtual stamp of approval” for the reliability and performance of ventilation systems for large environments. Manufacturers undergo extensive testing to demonstrate that their products are efficient under various conditions, meeting the demands of agricultural settings.
  2. Energy Efficiency: In an era where energy saving is paramount, BESS Lab certification places a strong emphasis on the energy efficiency of ventilation systems. Certified fans are evaluated for their ability to move air effectively while minimizing energy consumption, contributing to cost-saving and environmental sustainability.
  3. Compliance with International Standards: BESS Lab is a globally recognized lab. This allows companies with products with certified performance to access tenders, funds and government grants of various kinds rapidly and transparently.
  4. Market Competitiveness: Products with BESS Lab certification gain a competitive edge in the market. End-users and procurement professionals recognize the value of certification as an indicator of quality and reliability, influencing purchasing decisions in favor of certified fans.
  5. Respect for the Customer: We are still talking about air! Having certified performance means that the data reported in the brochures are real and not doped. For greater fairness and transparency towards those who want to buy a fan.


In the fast-paced world of industrial manufacturing, the BESS Lab certification for agricultural fans stands as a guarantee for quality, and efficiency. As industries and farmers continue to underline sustainability and operational excellence, the importance of reliable and energy-efficient equipment cannot be overstated.

Termotecnica Pericoli has always given priority to ensuring high-performing and quality products for its customers. Our R&D department designs and produces air circulation and exhaust fans with meticulous attention to detail.

Our prototypes undergo initial testing internally in our PERIlab. Once the prototyping phase is accomplished, our technicians fly to the University of Illinois to conduct official tests. All fans signed by Termotecnica Pericoli are BESS Lab certified (or in the certification process).
