The "ecowin Air Unit" is an outdoor air processing system that can supply air at comfortable temperatures and humidity even in extreme cold or heat. By simply connecting and installing it to commercially available air conditioners and air supply vents in homes and apartments, it enables humidification, cooling, dehumidification, and dust removal. The unit is powered by no electricity, has high weather resistance and durability, and features a simple, sturdy design that is hard to break. We also offer the "ecowin HYBRID," which enhances comfort and energy efficiency when used together. Please feel free to consult us. 【Features】 ■ Enables humidification, cooling, dehumidification, and dust removal just by connecting and installing to the air supply vent ■ Supplies air at comfortable temperatures and humidity even in extreme cold or heat ■ Can assist existing air conditioning systems and save energy ■ Easy installation ■ Removes PM2.5 as well *For more details, please refer to the PDF document or feel free to contact us.

The "DINNTECO-100plus" is a lightning rod that does not generate lightning phenomena and is based on a negative ion capacity type. It constantly neutralizes the charge within its protection range. The longer and slower the neutralization process takes, the smaller the generated current becomes, 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 the lightning surge caused by direct lightning strikes (the massive current generated when lightning strikes the 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 100 meters from direct lightning strikes ■ Over 6,000 installations worldwide in various facilities and equipment *For more details, please refer to the PDF document or feel free to contact us.

• Lightning protection

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 genuine products, will there be any issues with the warranty (such as response in case of failure)? A: There are no issues. We are covered by PL insurance, so we will handle matters related to product liability through the PL 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.

The "ecowinHYBRID" is a hybrid air conditioning system that combines the radiant heating and cooling device "EcoWin" with a high-performance convective air conditioner. It efficiently utilizes the heat/cool air from the air conditioner through radiant heat exchange, suppressing temperature unevenness in the space. It achieves a high level of health and comfort in air conditioning. *This product has received the "Encouragement Award" at the 27th Small and Medium Enterprises New Technology and New Product Awards.* ■ We are currently offering a technical document that outlines the benefits and case studies of implementation for free! ■ 【Comfort】 ・ A heating and cooling system that is gentle on babies, children, and the elderly ・ Cool in summer, providing comfort like being in a warehouse, and warm in winter, like being in a sunny spot 【Functionality】 ・ Uses an air conditioner as the heat source, allowing for quick startup with convective + radiant heating ・ The heat source air conditioner is recommended for gentle airflow operation, reducing the spread of viruses and bacteria 【Energy Efficiency】 ・ Ultra energy-saving with a maximum reduction of 34% * Evaluated by the Waseda University Environmental Research Institute, compared to standalone operation of high-performance air conditioners (during heating) * For more details, please refer to the catalog. Feel free to contact us with any inquiries.

"EcoWin" is a radiation-type heating and cooling air conditioning system. The heat medium is cold/hot water, allowing for a large amount of heat transfer, which has successfully reduced running costs significantly compared to existing air conditioners. Since it does not use wind, it operates silently, making it comfortable for sports 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 - Since it uses radiation for heating and cooling, the temperatures of the floor, walls, and ceiling are almost uniform. - In summer, it feels cool and comfortable like being in a warehouse, while in winter, it provides warmth like being in a sunny spot. ■ Safety - With low-temperature radiation, there is no risk of burns. It can be used safely by children and the elderly during evacuation. - It does not create wind, preventing dust from being stirred up, which helps reduce the risk of airborne infections. ■ Functionality - There is no wind and no operational noise from the unit. - Since it does not use wind, it does not stir up dust or pollen. ■ Energy Efficiency - Due to the effects of far-infrared radiation directly affecting the body, the perceived temperature difference is about 2°C cooler for cooling and 4°C warmer for heating compared to air conditioning. *For more details, please refer to the catalog or feel free to contact us.
