Antiviral special coating SIAA registered / water-based type

Antiviral environment for air conditioner filters! Entering the 7th wave: Effective infection control measures for this season, where ventilation is difficult during the scorching heat!

Newly developed water-based anti-virus and anti-bacterial special coating agent: GlossWell #930 AERO Type Anti-Viral. Development began urgently in the fall of 2020 when stronger virus countermeasures were urgently needed, and it was completed about six months later in February 2021. It contains a special type of quaternary ammonium salt as the main antibacterial component, providing anti-virus, anti-bacterial, and anti-fungal functions. [Establishing an anti-virus environment for air conditioning and ventilation system filters] ◯ Physically controls viruses attached to the filter ◯ SIAA registered: Testing method ISO 21702 Countermeasures against viruses in air conditioners and ventilation systems have been considered a difficult challenge, but with the special anti-virus coating formed by GlossWell #930 AERO, it is possible to apply physical virus countermeasures to air conditioning equipment. Since GlossWell #930 AERO is a water-based anti-virus special coating agent, it has a low viscosity level when forming the coating, which prevents it from clogging the fine pores of the filter.

Case Study: Improvement of a Transformer with Unstable Electrical Characteristics

A case study of stabilization through optimization of the impregnation process for a transformer that does not exhibit electrical characteristics.

【Consultation Details】 We received the following consultation from a device manufacturer: - The prototype transformer does not exhibit the expected electrical characteristics. - There is variability in the measurement values, and the characteristics are unstable. There should have been no issues in the design, but the actual prototype did not perform as expected, and the cause could not be identified. The request this time was for: "I would like you to impregnate it while the core is assembled." This was the specified process. Issues The electrical characteristics of the transformer were: - Unstable - Not reaching the design values To establish it as a product, stabilization of the electrical characteristics was necessary. < Hypothesis from Akita Transformer > After reviewing the situation, Akita Transformer proposed the following hypothesis: There is a possibility that the impregnation process is affecting the characteristics. Depending on how the impregnation resin enters and the state of the magnetic circuit, it is believed that there may be an impact on the coil and magnetic characteristics.
