The system is a new geothermal heat pump system introduced by Moriya Shokai, called the groundwater circulation type geothermal heat exchange system "Heat-Gw-Power." It involves filling a geothermal heat exchange tank constructed in the shallow underground (up to G.L. -3m) with river gravel and horizontally laying heat exchange pipes inside it. Groundwater is pumped from a nearby well and sprinkled from a distribution pipe installed above the heat exchange tank, allowing for heat exchange through infiltration and the heat exchange pipes. Additionally, there is a "CASCADE type" that further expands the effectiveness of this system. The CASCADE type underwent a one-year demonstration in the 2019 Ministry of the Environment's ETV project, receiving the ETV logo mark, and based on the performance evaluation results of this ETV, it was awarded a special prize by the judging committee in the product and business model category of the 2020 Energy Conservation Grand Prize. 【Features】 - Lower installation costs as heat exchange pipes are not inserted deep into the ground. - Heat exchange can occur regardless of climate as groundwater is sprinkled into the heat exchange tank as needed. - Groundwater sprinkled is allowed to permeate into the ground from the bottom of the geothermal heat exchange tank through a recharge well, ensuring reliable groundwater recharge. *For more details, please refer to the PDF materials or feel free to contact us.

The "Neplus Method" involves cutting and removing only the damaged upper part of the drainage ditch while preserving the still usable lower part, significantly reducing industrial waste. Additionally, it is an environmentally friendly method that reduces the work process, minimizes the materials used, and requires little to no heavy machinery, thereby also reducing CO2 emissions. 【Advantages】 ■ Construction waste reduced by 80% compared to conventional methods ■ Excavation residual soil reduced by 100% compared to conventional methods ■ Can be implemented even when structures are close together ■ Immediate traffic reopening for residents is possible ■ Significant reduction in construction and indirect costs, etc. *For more details, please download the PDF or contact us.
