Effects of using a moisture-absorbing agent (bamboo charcoal) in combination with an underfloor ventilation fan.
We highly recommend that customers who have already installed moisture control materials (such as bamboo charcoal) consider adding a subfloor ventilation fan. We will compare and verify the moisture control effects/performance of using only subfloor moisture control agents (bamboo charcoal) versus using both subfloor moisture control agents and mechanical ventilation through moisture absorption and desorption tests. *The operation time of the ventilation fan is under desorption conditions. By adding a ventilation fan to the subfloor where bamboo charcoal mats are installed, we confirmed improvements in ventilation and airflow effects, leading to enhanced moisture absorption and release efficiency of the bamboo charcoal mats and reduced drying time. Additionally, it is expected that the combined use of the ventilation fan will further improve moisture control performance, leading to a decrease in subfloor humidity and enhanced drying effects on wood moisture content.

Product condition and underfloor environment of the Dry Pro type-C after approximately 2.5 years of use.
This is a report on the inspection results after approximately two and a half years of using the Dry Pro Type-C in the newly added crawl space (foundation packing method) during the renovation. The inspection results showed that there was no dust or other substances adhering to the heat dissipation fins of the dehumidifier, the dehumidifying fins, the intake of the blower, or the fan that could negatively affect performance. Additionally, there were no foreign substances or dust adhering to the drain hose for dehumidified water or the pump tank that could adversely impact performance, and all components were functioning normally. (Photo: Heat dissipation fins of the dehumidifier) The newly added crawl space was located on the north side in a poorly ventilated area, but no signs of mold or condensation were observed, confirming that a dry state was maintained.

Heat management in the shed is urgent!
The heat inside the room may be caused by "heat trapped in the attic." In the summers of 2024 and 2025, extreme heat is expected to be even more severe than usual, with daily temperatures exceeding 35°C becoming the norm. Even with the air conditioning running at full capacity, are you experiencing issues like "the second floor is unusually hot" or "the room temperature doesn't drop even at night"? One of the causes of this is the heat trapped in the attic. When direct sunlight hits the roof, the temperature in the attic can reach nearly 70°C, compared to an outside temperature of 35°C. This heat radiates into the living space, not only raising the indoor temperature but also reducing the efficiency of the air conditioning, which can lead to increased electricity bills and negative health effects. ■ Start now! Efficient heat countermeasures with "attic ventilation" ■ Now is the perfect time to install it ahead of the summer peak ■ Attic ventilation is not just for summer * The attic ventilation system by Kazunosuke 24 is effective not only for summer heat but also for winter condensation prevention.

A deeper and newer vision of what should be - "Learning from the past to create the future."
In the 21st century, the way human society exists on a global scale is being questioned. In this era of rapid change, what kind of aspirations should we have when engaging in business? SEIHO's new concept naturally emerged from such inquiries. "Compassion" is the new concept. Rather than pursuing extravagant ideas, we want to delve deeper into a simple concept that everyone can be confident in. We wish to return to our origins to realize this concept. In a time when a diverse array of information is overflowing, misjudging the clear distinction between "purpose" and "means" can render even effective technologies futile. SEIHO will firmly place "principles, fundamentals, and essence" as the axis of our management decisions, learning from the wisdom of past sages while creating genuine technologies and services that benefit society.
