[Geothermal Drilling Work] For those considering the use of geothermal energy.

The construction record exceeds a total of 120 projects! We are operating on-site by overlaying the accumulated rich geological data.

"Geothermal drilling work" refers to the excavation of boreholes for heat extraction wells with a diameter of approximately φ179mm and a depth of around 100m. This involves inserting a ground heat exchanger (a single tube or WU tube made of high-density polyethylene material with a nominal diameter of 25-30A) into the borehole, and filling the space between the borehole wall and the U-tube with silica sand to construct the ground heat exchanger. It is primarily utilized for road heating systems that aid in snow melting and for heating and cooling systems in buildings. As of this fiscal year, the total number of completed geothermal drilling projects at a depth of around 100m has exceeded 120, with construction machinery and drilling methods suitable for the geological conditions proposed based on the extensive geological data accumulated since the company's establishment. When planning, designing, considering, or executing geothermal utilization, please feel free to consult or request our services. *For more details, please refer to the PDF document or feel free to contact us.
