GEOCLIP® U-Bend Pipe Separator
The GEOCLIP is a u-bend pipe separator, developed in 1999, by GBT, Inc. It utilizes geothermal technology and is designed to enhance vertical heat exchanger (VHE) performance, improving energy efficiency or heat transfer from 20-35%.
The GEOCLIP decreases borehole resistance, thereby significantly increasing the performance of a VHE and lowering the installation costs by shortening required VHE lengths.
About Typical Standard VHE Installations: A standard VHE installation has the two pipes that make up the u-bend pipe assembly either touching or in close proximity to each other. This type of assembly is less than optimal because the two pipes interfere with each others’ ability to exchange energy with the earth.
These u-bend pipes are usually encased with a 20% solids or thermally enhanced bentonite grout (often required by State regulations) in order to seal the borehole to prevent contamination of water aquifers below ground. Although the bentonite grout mixture is excellent for sealing the borehole, it has poor heat transfer characteristics in relation to surrounding soil or rock and acts as an insulator restricting energy exchange between the u-bend pipes and the surrounding soil.
To address this inefficiency, recent technology advances have yielded the design of the GEOCLIP u-bend pipe separator.
