The vacuum double glass tube, which collects heat through the power of vacuum and CPC reflectors, enables high-temperature solar heat of up to 200°C even in mid-winter.
The inner surface of a vacuum double glass tube is coated with a selective absorption film that converts sunlight into heat, and when sunlight is irradiated onto the glass tube, the temperature inside the tube rises to about 200°C. Because the gap between the double glass tubes is a vacuum, the interior of the glass tube is unaffected by the outside temperature, allowing it to collect high temperatures even in winter. Furthermore, a CPC reflector that concentrates sunlight is attached to the back of the glass tube, maximizing the amount of heat collected per installation area. There are flat plate, heat pipe vacuum tube, and U-pipe vacuum tube types of solar thermal collectors, but the "Solaris," which has a CPC reflector and uses the U-pipe vacuum tube type, has the highest heat collection amount per installation area. Various solutions are developed using this solar thermal collector as a heat source. One application is as a supplementary heat source for hot water boilers in facilities with high hot water demand, such as elderly care facilities, hospitals, and public baths. Another application is for central air conditioning in office buildings, large commercial facilities, and schools. Solar heat is also used in air conditioning systems for cooling, heating, and dehumidification. To prevent global warming, it is essential to create a society that minimizes the use of fossil fuels, and solar thermal utilization systems can significantly contribute to the protection of the global environment.

basic information
The conversion efficiency of solar power generation is about 15%, while the conversion efficiency of solar thermal utilization systems is around 50%, which is high. If we were to replace self-consumed energy with renewable energy, it would be desirable to use solar cells for devices that consume electricity and adopt solar thermal utilization systems for devices that use heat, such as water heating and air conditioning. Solar thermal utilization systems are commonly used as auxiliary heat sources for water heating boilers, but our vacuum tube solar thermal collectors can obtain high temperatures even in mid-winter, making them suitable for heating as well. Furthermore, by combining them with absorption chillers or adsorption refrigerators, they can also be used for cooling in the hot summer. Additionally, they are utilized for dehumidifying air conditioning in combination with desiccant air conditioners. In the future, as we promote ZEB (Zero Energy Buildings), the utilization of solar thermal systems will be an important factor.

Company information
Our company was established in 1917 as an ironworks company manufacturing steel structures, boilers, and more. Currently, our main products leverage our location for maritime transport to produce flue gas desulfurization systems for coal-fired power plants and steel plants. We have also introduced large five-sided machining centers and large horizontal boring mills, enabling us to carry out integrated production from sheet metal to machining of large industrial machinery, such as vacuum chambers for manufacturing glass substrates for LCD televisions. Furthermore, we are advancing the development of our own products, focusing on solar thermal energy, one of the renewable energy sources, and are engaged in the development and sales of vacuum tube solar thermal utilization systems. The applications of solar thermal utilization are expanding beyond just hot water supply to include heating, cooling, and dehumidification air conditioning. In the field of solar thermal utilization equipment, we have received numerous awards: - [2010] 6th Hiroshima Dream Energy Award, Special Prize - [2011] "Santop" 8th Eco Products Award, Minister of Economy, Trade and Industry Award - [2011] Lohas Design Award, Grand Prize in the Mono Category - [2012] 10th Japan Environmental Management Award - [2014] Fukuyama Environmental Award
