Case study of introduction to public facilities | Donation of solar thermal hot water system "ReTerra" to Nanao City

Creating hot water with the heat of the sun. Next-generation water heating system operating at 70W and 100V.

This is the hot water supply system "ReTerra," which utilizes solar heat to produce hot water. By harnessing solar thermal energy, it significantly reduces the energy load associated with hot water supply without relying on electricity or gas. The product features a mechanism that stores the collected heat in a hot water tank, and the system's power consumption is very low at approximately 70W, allowing it to operate with a 100V outlet. Therefore, it can also be powered by portable power sources or generators, making it useful for securing hot water and domestic water supply during disasters. Additionally, by using it in conjunction with existing hot water systems (gas or electric), it achieves both reduced utility costs and improved resilience. It can be introduced not only in new homes but also in existing residences, public facilities, and welfare facilities. This system is ideal for those considering both environmental measures and disaster prevention strategies.

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or variations in dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repair without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized.

SPACECOOL Co., Ltd. will exhibit at the 12th Heat Countermeasure Exhibition, a specialized trade show focused on solving heat-related issues, to be held at Tokyo Big Sight from July 15 (Wednesday) to July 17 (Friday), 2026. At this exhibition, we will showcase products from the "SPACECOOL Consumer Products Lab.," including the "SPACECOOL Umbrella Type 2," which will be launched in June 2026, as well as products currently under development. The "SPACECOOL Fabric Type 2" used in the exhibited products significantly suppresses the intrusion of heat from sunlight and promotes heat dissipation by radiating the heat transferred to the umbrella as infrared rays into space. The "SPACECOOL Umbrella Type 2" achieves high light-blocking and UV shielding performance, with a heat shielding rate of 80% (in the case of silver). We invite you to visit our booth when you come to the venue. Exhibition Overview: Dates: July 15 (Wednesday) to July 17 (Friday), 2026, 10:00 AM to 5:00 PM (until 4:00 PM on the final day) Venue: Tokyo Big Sight, East Hall 7 Our Booth Number: 7-ZF13 *Advance registration is required for attendance (free of charge).

"MI-170 series" With RS-232C communication, measurement result output and setting data input/output can be performed. Up to 8 types of condition settings, such as upper and lower limit settings, can be configured. Pressure sensors can be selected from 4 types based on accuracy, gauge pressure, and differential pressure. The mounting size conforms to the DIN96 standard. By combining with the separate type air leak tester LPU-100 series, it can also be used as an air leak tester. "DG-960 series" Pressure sensors can be selected from 4 types based on accuracy, gauge pressure, and differential pressure. The mounting size conforms to the DIN96 standard. "MIZ-0175 series" A new multi-indicator that enhances the functionality of the versatile and high-performance conventional model "MI-170," improving operability and visibility through downsizing and the adoption of an LCD display. It allows a maximum sampling rate of 4000 times per second for stable measurements and is equipped with various correction functions and noise cancellation features, providing a wealth of functionalities.
