The "Electrocorrosion Countermeasure Series" uses ceramic, an insulating material, for the internal balls of the ball bearings, which differs from the standard. The appearance, performance, functionality, and specifications of the fan motor are the same as the standard products. This countermeasure type is deployed in environments where electrocorrosion occurs, and it is evaluated based on field performance. However, it does not guarantee electrocorrosion resistance in all environments, so please ensure thorough confirmation and verification before use. For more details, please contact us or refer to the catalog.

The dual reverse fan is a product that improves airflow characteristics by having the fan motor's rotation direction set to the reverse wind direction (with reversed blade pitch) while maintaining the same direction. It is ideal for equipment with high implementation loads. Compared to dual series operation, there was a 25% improvement in thermal efficiency and a 40% increase in airflow, resulting in improved implementation load (according to measurements by Hirozawa Seiki Co., Ltd.). It is available in various sizes. For more details, please contact us or refer to the catalog.

At Hirozawa Seiki Manufacturing Co., Ltd., we realize cooling systems tailored to the diverse needs of our customers through order production. By manufacturing fan units as part of our operations, we have achieved shorter delivery times. Additionally, by supplying fan units, we can reduce the labor involved in secondary processing and lower logistics costs. Furthermore, we ensure quality through double inspections of both standalone fan motors and completed fan units. For more details, please contact us or refer to our catalog.
