When installing a digital mammography device in a screening vehicle, the X-ray detector used has poor temperature characteristics, leading to issues such as equipment performance degradation and operational instability due to extreme interior temperatures (especially when parked) during summer and winter. To address this, we created a heating device inspired by our already commercialized heat-retaining warmer. Even when parked, the heat-retaining material inside the heating device continues to warm the equipment without needing power, allowing for thermal protection of the device until the next day without having to keep the engine running. [Challenges] - It is difficult to operate the digital mammography device for vehicle use. - An air conditioning unit was installed for vehicle adaptation, 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 heat from sunlight 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 storage material naturally absorbs heat to suppress the temperature increase. After sunset, when the indoor temperature drops, the storage material naturally releases heat, helping to moderate the room temperature. This product efficiently utilizes solar heat and living heat, enhancing the comfort of living spaces and supporting a smart eco-friendly lifestyle. 【Features】 - The 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 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.

"@YukadanP-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 thermal storage underfloor heating, the unit is thicker to ensure heat retention, 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 thermal storage method provides lasting warmth ■ Thickness of 12mm, suitable for renovations ■ Economical and safe heat pump ■ Excellent insulation effect with latent heat storage material *For more details, please refer to the PDF document or feel free to contact us.
