Thermo Helix-Piles are Thermopiles with helical shear rings attached and can be used in all applications where Thermopiles are appropriate. At one time, individual rings were used instead of the helix. Most applications use a helix that has a strip width of 2 inches (50mm). Generally, Thermo Helix-Piles support greater loads than adfreeze piles.
Sloping Evaporator Thermoprobes are found on the majority of existing passive subgrade cooling system installations beneath slab-on-grade structures. These units utilize a sloped evaporator to insure that the condensate will flow from the condenser to the lowest portion of the evaporator. Typically, evaporator slopes are between 10% and 3% - with the median being 5%.
Thermoprobes with buried condensers are designed to release the heat picked up from the subgrade through the near surface soils or embankment. A typical application for these units is in roadway or airfield sections where heat is released just under the pavement. The condensers can be coupled to either vertical or sloping evaporators.
