Measures against condensation in summer! Condensation and corrosion within wall structures are often difficult to detect.

In 2020, the "mandatory energy-saving standards for housing" are scheduled to be implemented, and it is expected that Japanese housing will increasingly aim for high airtightness and high insulation. However, at the same time, measures against condensation during the summer must be considered. In a site where glass wool was filled using the 2x4 construction method and a vapor barrier was installed on the interior side, significant corrosion due to condensation occurred. It is believed that the interior became hot and humid, leading to condensation as it was cooled by the air conditioner on the inside. The hold-down hardware also showed white mold, and if corrosion progresses like this, it will pose problems for the durability of the building. This type of summer condensation particularly occurs in regions with high temperatures and humidity, like Japan. Therefore, it is necessary to implement sufficient measures against winter-type condensation while simultaneously preventing summer-type condensation. *For more details, please refer to the PDF document or feel free to contact us.

The cause is a large amount of water vapor! The challenge is how to remove humidity and suppress mold and decay.

Foundation insulation is a method of insulating the foundation that faces the outside air. The period when the risk of condensation and mold is highest with foundation insulation is from June to September of the first year after completion. The main cause is the large amount of water vapor coming from the concrete floor. Especially, wood that contains a lot of moisture significantly deteriorates in strength, so it is important to be cautious considering durability against earthquakes and typhoons. As a solution to these humidity problems, our company has developed a dedicated underfloor dehumidifier called "Dry Pro." It effectively eliminates humidity and condensation, and is useful for preventing mold, pests, and decay fungi in the underfloor wooden components. (Patent and design application pending) 【Features of Dry Pro】 ■ Dehumidification capacity of approximately 400-600cc per day on humid days during the rainy season and summer ■ Circulates dehumidified air widely using a blower ■ Quiet design: 45/44dB ■ Standard equipped with phytoncide that has deodorizing effects *For more details, please refer to the PDF materials or feel free to contact us.

After about one month, a drier condition (wood moisture content 12%) was confirmed!

"Dry Pro" is a floor underfloor dehumidifying fan that effectively eliminates moisture and condensation, and is effective against mold, pests, and decay fungi in the wooden parts under the floor. Assuming the early stages of new construction using foundation insulation methods, 36 liters of water were sprayed on the underfloor foundation of each building, and dried wood (cedar) was installed to measure the moisture content of the wood and the humidity under the floor. As a result, the buildings where this product was installed gradually dried out by repeatedly operating the dehumidification process every day, and after about two months, an average of approximately 70% RH dry condition was confirmed even outside of dehumidification operation hours. [Experiment] ■ Test House A - Floor area approximately 10 tsubo - Underfloor with foundation insulation method (Dry Pro installed) ■ Test House B - Floor area approximately 10 tsubo - Underfloor with foundation insulation method (without dehumidifying fan) *For more details, please refer to the PDF document or feel free to contact us.

Thank you very much for visiting our company website and catalog, and for your interest in our diesel engine generators. From customer surveys, the most common feedback we received was: - I want to see the actual generators that have been installed. - I want to see them operating under real load. - I want to hear the opinions of companies that have installed them. - I want to see the generators in operation before making a purchase. After all, it’s understandable to feel worried about purchasing a generator without seeing the actual unit first, right? As the saying goes, "Seeing is believing," so we will be holding this tour. It will take place in that area of the Kanto region, where summer temperatures exceed 40°C. We successfully operated our generators this summer as well, so we are confident in handling the heat (sweat). Additionally, it has been confirmed that our generators equipped with the world-leading "Scania engine" are "fuel-efficient." This will surely help reduce daily operating costs. Please note that while we will provide kind and courteous assistance, the meeting and dispersal will be at the site (transportation costs and other expenses will be borne by the customer), so please understand this in advance.

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.

In Tochigi Prefecture, located in the northern part of the Kanto region, several ground-mounted power plants utilizing Grace Solar's aluminum alloy solar mounting systems are being constructed smoothly and have begun operations. Grace Solar planned the tilt angles and foundation types of the mounting systems based on precise topographical and meteorological data from the design stage. The high-strength aluminum alloy mounting systems are lightweight yet effectively suppress snow accumulation, ensuring stable operation of the system even during harsh winter conditions. The aluminum alloy mounting systems adopted in this project are treated with a special anti-corrosion coating on the surface, allowing them to adapt to the environment of Tochigi Prefecture, which experiences significant temperature differences and seasonal humidity changes. This effectively delays material degradation and extends the overall lifespan of the system. Going forward, Grace Solar will continue to focus on the characteristics and environmental requirements of each region, supporting more solar power generation projects in Japan and around the world through customized mounting solutions, and providing sustainable and reliable support for renewable energy infrastructure.
