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.

The "Dry Pro" electronic dehumidifying and air blowing unit for underfloor use is a product designed for moisture control and condensation prevention in crawl spaces without ventilation openings or with sealed underfloors. It is a compact dehumidifier that can be easily installed and constructed with just a 22mm hole. The dehumidification operation can be switched between "normal (strong)" and "weak," with electricity costs of approximately 1,720 yen per month for normal operation and about 1,040 yen for weak operation. *Based on 8 hours of operation per day for 30 days, with the blower and dehumidifier running, and 1 kWh = 27 yen. On humid days during the rainy season or summer, it has a dehumidification capacity of about 400 to 600 cc per day, effectively eliminating moisture and condensation, and is useful for preventing mold, pests, and decay fungi in wooden structures under the floor. 【Features】 ■ Easy installation if a Φ22 hole is drilled for drainage! ■ Dehumidified air is circulated widely by the blower. ■ Equipped with fitonchid, which has deodorizing effects, as standard. ■ Patent and design application pending. ■ Fully automatic operation with a dedicated controller. *Please note that [demo visits] may not be available in certain regions. Thank you for your understanding in advance. *For more details, please refer to the PDF document or feel free to contact us.

"Dry Pro" is an electronic dehumidifying and ventilation unit designed for underfloor use, which combines a Peltier cooling device and a diffusion-type fan to dehumidify the entire underfloor area and suppress the occurrence of moisture and condensation. It is a system that can dehumidify the space between the foundation and the floor, suitable for housing construction methods that lack ventilation openings. On humid days during the rainy season or summer, it has a dehumidification capacity of approximately 400 to 600 cc per day, effectively eliminating moisture and condensation, and is effective against mold, pests, and decay fungi in the wooden parts under the floor. 【Features】 ■ Demonstration visits available ■ Easy installation if a 22 mm drain hole can be made ■ Includes Fittonia ■ Circulates dehumidified air widely with a fan and deodorizes with Fittonia *For more details, please refer to the PDF document or feel free to contact us.

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.

"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.

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.

Introducing SEIHO's unique facilities, measuring devices, and instruments for conducting a wide range of tests, experiments, and measurements repeatedly.
