Product condition and underfloor environment of the Dry Pro type-C after approximately 2.5 years of use.

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.

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.

Japan is one of the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of major earthquakes occurring. Regarding the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake countermeasures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" For more details, please download the materials or contact us.

[To the owners of parking lots and parking lot construction companies] "I am worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those particularly facing sidewalks or roadways are expected to pose risks of dangerous incidents such as pedestrian collisions and vehicle-to-vehicle accidents. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surrounding area with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask that you arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.
