When equipping a digital mammography device in a screening vehicle, the X-ray detector used has poor temperature characteristics, leading to issues such as device performance degradation and operational instability due to extreme interior temperatures (especially when stationary) in summer and winter. Therefore, we created a heating device inspired by our already commercialized heat-retaining warmer. This heating device continues to warm the equipment using the heat-retaining material inside, without requiring power even when stationary, allowing for thermal protection of the device until the next day without needing to keep the engine running. [Challenges] - It is difficult to operate the digital mammography device as a vehicle-mounted unit. - An air conditioning system was installed for vehicle mounting, but it was very inefficient. *For more details, please refer to the related links or feel free to contact us.

The "Energy Board PS" is a latent heat storage material that stores solar heat entering during winter, as well as heat emitted from heating, lighting, and the human body, naturally regulating the indoor temperature. When the indoor temperature rises due to sunlight during the day, the heat storage material naturally absorbs heat to suppress the temperature increase. After sunset, when the indoor temperature drops, the heat storage material naturally releases heat, helping to moderate the room temperature. This product efficiently utilizes solar and living heat, enhancing the comfort of living spaces and assisting in a smart eco-friendly lifestyle. 【Features】 - The heat storage material naturally absorbs heat to suppress temperature increases when the indoor temperature rises due to sunlight during the day. - After sunset, when the indoor temperature drops, the heat storage material naturally releases heat, helping to moderate the room temperature. - It stores heat emitted from heating, lighting, and the human body, naturally regulating the indoor temperature. - Zero utility costs. *For more details, please refer to the PDF document or feel free to contact us.

"Kanai Danzen" is a heat pump-based thermal storage heating and cooling system. Using energy-efficient heat pump equipment as the heat source, it utilizes inexpensive nighttime electricity to heat (store heat) latent heat storage material in winter. During the day, the indoor air comes into direct contact with the latent heat storage material, allowing for heat exchange to create warm or cool air, which is then returned indoors. The heated latent heat storage material continues to release heat at a steady temperature, allowing for long-term heat exchange with the indoor air, thereby maintaining a nearly constant indoor temperature. [Features] - An eco-friendly and economical system achieved by utilizing heat pumps and nighttime electricity. - The heat source is outdoors, and the box is located under the floor, keeping the indoor space tidy. - Performance testing in high-insulation homes has achieved long-duration heating. - Long operating times are possible due to the use of high-performance latent heat storage materials. *For more details, please refer to the PDF materials or feel free to contact us.

"@Yukadan P-Lus" is an eco-friendly and warm heat pump underfloor heating system. It operates the heat pump to heat the thermal storage material while also warming the floor surface, and it utilizes the sunlight that enters during the day for the underfloor heating system. In the case of storage-type underfloor heating, the units are thicker to secure the heat, and in renovations, it was necessary to remove the floor and perform base work. However, with a thickness of 12mm, it is possible to install it over existing flooring depending on the conditions. [Features] ■ The heat source has about three times the energy-saving effect of electric heat pump underfloor heating. ■ The storage method allows warmth to last longer. ■ At 12mm thick, it is suitable for renovations. ■ An economical and safe heat pump. ■ Excellent insulation effect with latent heat storage material. *For more details, please refer to the PDF materials or feel free to contact us.
