Nuclear fans | CBI Group

Fans for the nuclear sector

Industrial fans for the nuclear sector provide essential support for a wide range of operations, including reactor cooling, plant ventilation, radioactive gas extraction, and nuclear fuel cooling.

Each fan is designed to ensure maximum efficiency while complying with the safety standards required by the most complex nuclear environments.

In the past year alone, more than 30 ventilation systems for nuclear applications have been successfully installed, confirming CBI Group’s ongoing commitment to technological excellence and operational reliability in one of the most demanding industrial sectors.

Nuclear plants require ventilation systems that comply with extremely strict operating requirements. CBI solutions are designed to meet industry regulations, helping reduce risks and protect personnel health across all areas of the plant.

Discover how CBI Group’s engineering expertise helps address the daily challenges of maintenance by providing technical support, on-site inspections, and structured maintenance planning to keep systems operating at the highest level of efficiency.

Certifications and regulatory compliance

CBI Group ensures that all ventilation solutions for the nuclear sector meet the highest quality standards. Production processes are certified according to ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018, confirming our commitment to excellence in manufacturing and service.

The new frontiers of nuclear ventilation

In nuclear plants, fans are not just components: they are essential elements for ensuring controlled environments, preventing contamination, and supporting the safe operation of the plant.

CBI nuclear fans combine mechanical strength, air tightness, advanced sealing systems, and long-term durability.

Each unit operates reliably even under extreme temperature, pressure, and environmental conditions, helping maintain a stable and safe atmosphere in all areas of the plant. Advanced materials and coatings ensure resistance to corrosion, radiation, and thermal stress, while regular quality checks guarantee performance in line with international standards.

Fans designed for seismic requirements

In critical sectors such as the nuclear industry, the reliability of industrial fans is essential. To ensure the highest standards of safety and operational continuity, each batch undergoes a rigorous seismic verification process.

Fans designed for environments subject to seismic requirements are divided into two categories:

Shutdown fans
Simulated to verify structural resistance and the ability to restart after a seismic event.
Continuous fans
Tested on vibrating platforms to ensure continuous operation without interruption.

When a customer orders a batch of fans for the nuclear sector, we always manufacture a prototype for preliminary tests and inspections, in order to guarantee reliable performance in all conditions.
