[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 fan. When there is a high amount of water vapor, only the diffusion fan operates, and when it is low, the exhaust ventilation system also operates to bring in dry air from below the floor. POINT 1: Optimal independent operation of exhaust and air supply with absolute humidity sensor POINT 2: Optimal deodorization operation with standard phytoncide POINT 3: Detects abnormalities in the underfloor ventilation fan and water issues, displaying them on the controller. 【Features】 ○ Effective against underfloor humidity, condensation, and mold ○ Powerful exhaust and diffusion For more details, please contact us or download the catalog.

• Ventilation and Exhaust

Exhaust type + stirring type unit type

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

• Ventilation and Exhaust

A comfortable indoor environment! Prevents condensation and extends the lifespan of the building.

The underfloor ventilation "Kazetaro" maintains a comfortable condition for wood by forcibly introducing air into the underfloor space. It is particularly effective in eliminating condensation. Underfloor ventilation also affects the indoor environment, reducing the conditions for the growth of dust mites and mold, which benefits the health of the family. The Kazetaro unit uses a hybrid sensor to detect the amount of water vapor (humidity) in the outside air, and the hybrid controller independently controls the Kazetaro blower type and Kazetaro mixer type, creating optimal ventilation operation for the wood under the floor. 【Features】 ○ Improves ventilation effectiveness to prevent pest breeding ○ Forcibly introduces air into the underfloor space to prevent condensation ○ Maintains a comfortable condition for wood, extending the lifespan of the building ○ Reduces the conditions for the growth of dust mites and mold, making the indoor environment comfortable For more details, please contact us or download the catalog.

Equipped with a water immersion sensor! Detects leaks due to flooding under the floor, deterioration, and damage to drainage pipes, etc.!

"Kazutarou Basic" is a localized underfloor ventilation system designed to address areas prone to high humidity and stagnation, such as water-related areas and the north side. Equipped with a flooding sensor, it quickly detects not only underfloor flooding due to water damage but also leaks caused by deterioration or damage to drainage pipes, providing peace of mind by alerting you to abnormalities. We offer two models: the timer type with a flooding sensor, "Kazutarou Basic SS," and the standard timer type, "Kazutarou Basic." 【Features】 ■ Equipped with a flooding sensor ■ Detects underfloor flooding and leaks due to deterioration or damage to drainage pipes ■ Supports environments where natural ventilation is insufficient with forced ventilation ■ Safety measures against increasing underfloor flooding and leaks *For more details, please refer to the external link page or feel free to contact us.

Contributes to the prevention 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 blowing 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 construction, a new model "TYPE-C" compatible with foundation packing construction 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 parts under the floor. Furthermore, with the version upgrade in June 2024, a powerful dehumidification operation mode will be added. The surrounding temperature range for dehumidification operation (low-temperature dehumidification operation range) has been expanded, allowing operation at 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 fluorine-free 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 "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If you require a detailed technical explanation, please contact us.

[To the owners of parking lots and parking lot construction companies] "I'm worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those facing sidewalks or roadways are particularly prone to dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surroundings 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 customers to 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.
