The "DINNTECO-100plus" is a charge ion capacity type lightning rod that does not generate lightning phenomena. It constantly neutralizes the charge within the protection range. The longer and slower the neutralization time, the smaller the generated current, preventing discharge (lightning). As a result, there is no damage to electronic devices or networks, and there is no impact on the surrounding area. It solves the significant issue faced by conventional lightning rods, which is lightning surges caused by direct lightning strikes (the massive current generated when lightning strikes the lightning rod, leading to electrical and electronic damage). 【Features】 ■ Prevents sudden lightning phenomena due to the slow neutralization of charge ■ No damage to electronic devices or networks ■ No impact on the surrounding area ■ Protects within a maximum radius of 100m from direct lightning strikes ■ Over 6,000 installations worldwide in facilities and equipment *For more details, please refer to the PDF document or feel free to contact us.

The "ecowin filter" is an antiviral and antibacterial air conditioning filter that can be easily installed in your current air conditioner. It suppresses the growth of various bacteria, viruses, and mold through the sterilizing power of copper ions contained within the filter. The ecowin filter has passed the "Antiviral Performance Test JIS L1922:2016," which targets enveloped viruses. It is recommended for antiviral measures during the air conditioning season in the peak summer when constant ventilation is difficult. To ensure that customers are aware of the strong antiviral measures, the filter itself is labeled with "Antiviral, Anti-MRSA, Anti-Mold" and "MADE IN JAPAN." Q: Since it is different from the genuine product, will there be any issues with the warranty (such as response in case of malfunction)? A: There are no issues. We are covered by PL insurance, so we will handle any matters related to product liability through the insurance. However, if you install the ecowin filter in an air conditioner with a filter reset or dust sensor, there is a risk that the filter may get caught and cause the air conditioner to malfunction, which would not be covered by PL insurance, so please avoid installing it near the sensor drive components.

"EcoWin" is a radiant heating and cooling air conditioning system. The heat medium is cold/hot water, which allows for a large amount of heat transfer, successfully reducing running costs significantly compared to existing air conditioners. Since it does not use air, it operates silently, making it comfortable for sports that are affected by wind, such as badminton. It is recommended for large spaces like gymnasiums, both from a sports perspective and as a disaster prevention base. 【Features】 ■ Comfort - Radiant heating and cooling provide nearly uniform temperatures on floors, walls, and ceilings. - In summer, it feels cool and comfortable, like being in a warehouse; in winter, it feels warm, like being in a sunny spot. ■ Safety - Low-temperature radiation eliminates the risk of burns. It can be safely used by children and the elderly during evacuation. - The absence of wind prevents dust from being stirred up, which helps reduce the risk of airborne infections. ■ Functionality - There is no wind or operational noise from the unit. - Since it does not use air, it does not stir up dust or pollen. ■ Energy Efficiency - The effect of far-infrared rays directly impacts the body, resulting in a temperature difference of about 2°C for cooling and 4°C for heating compared to traditional air conditioning. *For more details, please refer to the catalog or feel free to contact us.*

The Solar Self-Maintenance Coat prevents dirt on solar power (solar) panels and helps maintain their power generation efficiency. Dirt such as exhaust gas, yellow sand (dust), volcanic ash, and pollen that adheres to solar power (solar) panels can cause a decrease in power generation efficiency. Therefore, the Solar Self-Maintenance Coat suppresses dirt adhesion with its anti-static function and makes it easier for rainwater to wash away dirt with its super hydrophilic function. This helps reduce the decrease in power generation efficiency caused by dirt and decreases the frequency of cleaning maintenance. It is a new anti-dirt coating that addresses challenges that could not be solved with photocatalytic coatings. 【Features】 ■ Prevents static electricity and dirt adhesion ■ Super hydrophilic self-cleaning effect allows dirt to be washed away by rain and flowing water ■ 100% inorganic components, environmentally friendly ■ Hard coat makes it resistant to scratches with a durability of over 10 years ■ Resistant to chemicals, strong against animal waste ■ High transparency and low refraction prevent cloudiness *For more details, please request materials or download the catalog.
