Company A, which manufactures and sells various electrical appliances, is focusing on developing medical refrigerators for transporting and storing vaccines, medicines, and other items in response to the spread of the new coronavirus infection.
Mr. B from Company A's Technology Development Department, who was in charge of developing a new medical refrigerator, explains it this way:
"Initially, we thought about reusing the fans from an overseas manufacturer that we had used in our previous products. Refrigerators installed in places like public health centers and hospitals are used in close proximity to people, so noise levels need to be kept as low as possible.
In addition, since pharmaceuticals such as vaccines require strict temperature control, we must avoid situations where the stored pharmaceuticals become unusable due to equipment failure. When developing this new equipment, we also thought it would be a good idea to reconsider the power supply for the equipment and the fans used to cool the circuit boards.
*For more information on noise, see Knowledge Fan Basics: Fan Noise and Sound Pressure Levels
While continuing to gather information in search of a reliable, low-noise fan, Mr. B came across SANYO DENKI CO., LTD. 's website.
"I learned that SANYO DENKI CO., LTD. 's products have a long track record of being used in equipment that requires reliability and quietness, such as medical equipment." (Mr. B)
Intrigued, Mr. B immediately contacted SANYO DENKI CO., LTD. to inquire about cooling fans.
After listening to Mr. B about the issues he is facing with the refrigerator he is developing, the SANYO DENKI CO., LTD. sales representative recommends the "San Ace" 9RA type DC Cooling Fan (size 92 x 25 mm).
"When we compared the catalog values with fans from an overseas manufacturer that were used in previous models, we found that the air volume and static pressure were equal or better, while noise levels were reduced. We were also told about the company's efforts to ensure high quality and reliability, such as their in-house evaluation tests and inspection system during manufacturing." (Mr. B)
San Ace has continued to develop its products while maintaining high reliability since it first appeared in Japan in 1965. Based at two technology centers in Ueda City, Nagano Prefecture and the Subic Special Economic Zone in the Republic of the Philippines, San Ace designs and develops highly reliable, high-performance fans.
All DC Cooling Fan models use ball bearings that stabilize the load during rotation and a rotor cover that secures the magnet and blades, ensuring high reliability and a long life.
In terms of production technology, we have accumulated the skills to provide high-quality products. For example, we manufacture our own precision molds to achieve high-quality manufacturing in a short period of time. In addition, during the production process, we carry out balance corrections and inspections on all fans, which greatly affect the lifespan and reliability, and we are committed to production using the most specialized technology.
After that, Mr. B obtained a sample and performed an evaluation. As a result, he was able to confirm that the noise level could be reduced while still satisfying the cooling performance even when the device was installed. He also confirmed that the power consumption could be reduced, and he soon decided to adopt the product.
"They introduced us to a low-noise fan, which helped us overcome the noise issue. Furthermore, we learned that SANYO DENKI CO., LTD. 's fans have a long track record of being used in equipment where reliability is important, such as medical equipment and data centers, and that they are committed to manufacturing high quality and reliability, including conducting rigorous in-house evaluation tests and 100% inspections. This gave us confidence in their high reliability.
Furthermore, they were flexible in responding not only to the product specifications but also to our requests for customization, such as the installation of connectors. As a result, we were able to significantly reduce the amount of assembly work required within our company, and we have established a system for the speedy manufacture and sale of medical refrigerators. SANYO DENKI CO., LTD. 's cooling fans have a wide lineup in addition to the size and voltage specifications we adopted this time, so we would like to actively consider using them in future product developments." (Mr. B)
