We have opened a service site for the heat-shielding and radiative cooling paint "Radicool"! It is a high-performance material that contributes to compliance with regulations, heat stress measures, and energy conservation.

There are cases where the internal ceiling temperature has been reduced by about 20 degrees! The cutting-edge class of 'heat insulation + radiative cooling technology (high reflection + high radiation)' improves the high-temperature issues indoors! CO2 reduction as well.

We would like to introduce the cooling effect of our product 'Radi-Cool.' It is a high-performance coating that combines heat insulation and radiative cooling effects. By applying it to roofs and windows, it helps lower indoor temperatures and perceived temperatures, contributing to reduced air conditioning costs. With the addition of the technology of 'radiative cooling,' which allows materials to release absorbed heat through thermal radiation, it exhibits even higher cooling effects than insulation and heat-blocking materials! 【Examples】 - Automotive Manufacturer Service Center: Coated the roof → The internal temperature of the ceiling dropped to about 33°C without air conditioning running. The perceived temperature decreased, contributing to reduced air conditioning costs. - Trading Company Distribution Center: Coated the roof → A maximum temperature difference of about 20.7°C in the ceiling before (July) and after (August) coating! Improved working environment with a cool feel even in summer! - Public Transportation Agency: Applied to outdoor units to prevent high-pressure cuts → The internal temperature of the outdoor unit dropped by 3°C compared to using a sprinkler system, and the effectiveness and CO2 reduction were appreciated! *For more details, please download the PDF or feel free to contact us.

• Heat-insulating paint for exterior walls (roofs, rooftops, etc.)

Conducted tests according to automotive specifications (Nissan Motor Company internal standards) to confirm the maintenance of cooling performance.

At Nissan Motor Co., Ltd., we conducted performance verification of "Radi-Cool." In the salt spray test, which evaluates paint adhesion, we confirmed that the surface of the painted board cooled approximately 7°C more than conventional painted boards. In the weather resistance test using xenon irradiation, we demonstrated that there were no structural changes or changes in radiative cooling performance. Additionally, we can confirm the maintenance of cooling performance, as the untreated wall side in the logistics warehouse was nearly 30°C, while the treated roof surface was in the low 20s°C. 【Durability Test Details】 ■ Salt Spray Test (Paint Adhesion) ■ Weather Resistance Test (Xenon Irradiation) *For more details, please download the PDF or feel free to contact us.

• Heat-insulating paint for exterior walls (roofs, rooftops, etc.)

Achieves even higher cooling effects than insulation and heat shielding materials! Cooling paint that can reduce the increase in power consumption for heating.

"Radi-Cool" is a paint that combines heat insulation and radiative cooling effects. As a result of verifying winter heating power consumption, it was demonstrated that the increase rate of heating power consumption in buildings treated with this product is 3.2% or less compared to untreated buildings. By applying it to roofs and windows, it helps lower indoor temperatures and perceived temperatures, contributing to reduced air conditioning costs. [Winter Heating Power Consumption Verification Details] ■ Air Conditioning Setting: Indoor temperature set to 21℃ ■ Measurement Period: January 4, 2020 - February 16, 2020, outdoor temperatures 0-12℃ *For more details, please download the PDF or feel free to contact us.

• Heat-insulating paint for exterior walls (roofs, rooftops, etc.)

Achieved an average energy-saving rate of approximately 57% during summer operation! Radiative cooling technology that improves high indoor temperature issues.

"Radi-Cool" is a paint that, when applied to roofs and windows, lowers indoor temperatures and perceived temperatures, contributing to reduced air conditioning costs with its heat insulation and radiative cooling effects. In a summer energy-saving verification, it was confirmed that during air conditioning operation, the maximum daily energy savings rate was 63.4%. The indoor temperature when air conditioning was not in operation reached a maximum of 16°C.

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.

We have introduced Majesta Fragrance to a nightclub in Yokosuka City, Kanagawa Prefecture, creating a fragrant atmosphere throughout the floor. The model we have introduced is the "MF-02S," which costs 8,800 yen per month (tax included). The scent you have chosen this time is "Sabon," a high-quality soap fragrance reminiscent of luxury hotel amenities. Its clean and transparent refreshing scent spreads throughout the entire floor, warmly welcoming customers who visit. By introducing scent design to the nightclub, we can enhance the extraordinary experience and create a memorable space that lingers not only visually but also through "scent." Majesta Fragrance offers a rental service for commercial aroma diffusers, and we also provide a free trial installation. If you are interested in scent design, please feel free to contact us.
