This is a construction method that allows construction of underground heat exchangers, which used to be installed from 150 to 200 meters, to be more than 300 meters deep, improving economic efficiency due to increased thermal efficiency.

Increasing the depth of construction by using a load band

> Load bands and load attachments are installed outside the underground heat exchanger, increasing the depth of construction by 150-200% or more compared to the existing general technology.
> Increased depth of construction greatly improves thermal conductivity of individual geothermal holes
> Compared to conventional general technology, the total depth of perforation is reduced and the amount of perforation is reduced by up to 50%.
> Geothermal systems can be applied even in urban areas where installation sites are small due to the reduced area of the site required for installation.
> Minimized thermal interference due to sufficient distance between geothermal spaces
