[Revised Edition] Guide to Underfloor Measures That Must Be Checked and Addressed After Heavy Rain Disasters

Exhaust type + diffusion type unit! A subfloor ventilation series that detects humidity conditions and draws in dry air from beneath the floor.

The system detects the amount of water vapor (absolute humidity) and independently controls the exhaust ventilation system and the diffusion-type blower. When there is a high amount of water vapor, only the diffusion-type blower operates, and when it is low, the exhaust ventilation system operates in conjunction, bringing in dry air from below the floor. POINT 1: Optimal independent operation of exhaust and blowing with absolute humidity sensors POINT 2: Optimal deodorization operation with standard phytoncide POINT 3: Detects abnormalities in the underfloor ventilation fan and underfloor water issues, displaying them on the controller. 【Features】 ○ Effective against underfloor moisture, condensation, and mold ○ Powerful exhaust and diffusion For more details, please contact us or download the catalog.

Contributes to the suppression of condensation and mold under the floor. A new model compatible with the foundation packing method has been introduced.

The "DRY PRO" Ver3 is an electronic dehumidifying and ventilation unit for underfloor use, combining a Peltier cooling device with a dedicated stirring and diffusion-type blower. In addition to the diffusion-type model "TYPE-D" for foundation insulation methods, a new model "TYPE-C" compatible with foundation packing methods has been added to the lineup. It can dehumidify even in areas where moisture tends to accumulate by stirring a wide range of air. It helps suppress moisture and condensation under the floor, contributing to the prevention of mold, pests, and decay fungi in wooden components. Furthermore, with the version upgrade in June 2024, a powerful dehumidification operation mode has been added. The surrounding temperature range for dehumidification operation (low-temperature dehumidification operation range) has been expanded, now accommodating surrounding temperatures down to 5°C. 【Features】 ■ Easy installation with a φ22 drainage hole (no drainage pump required) ■ Automatic operation possible with a dedicated indoor controller ■ The direction of the aluminum duct of the blower can be set freely ■ Dehumidification capacity of 1800mL per day (depending on conditions) ■ Uses non-fluorinated electronic cooling technology ■ Compatible with underfloor flooding sensors (optional) *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.
