Earth tube

Earth tube

Ventilation air intake tube, usually measuring 8 or more inches in diameter and buried 5 or more feet below grade. Earth tubes take advantage of relatively constant subterranean temperatures to preheat air in winter and precool it in summer. In humid climates, some earth tubes develop significant amounts of condensation during the summer, potentially contributing to indoor air quality problems.

Each Drawer Magnet has three high-powered rare earth tube magnets, which can be removed from the front for cleaning.
Magnet strength was also a key issue, as the new Grates would be replacing far weaker Rare Earth Tube Magnets supplied by another company.
Metal Detector/Separator new rare earth tube magnet
More particularly, Eriez will exhibit their new Megastrength Rare Earth (RE) Tube Magnet, which offers over 50% more pulling power on the surface of the tube than Standard Rare Earth Tube Magnets, thus ensuring outstanding performance in the removal of very fine iron or weakly magnetic contaminants, particularly important in processing applications involving foodstuffs.
Their new Megastrength Rare Earth Magnetic Tube now offers 60% more pulling power than traditional Rare Earth Tube magnets, they assure us.
There will also be a representative display of their range of magnetic separators for the removal of fine iron contamination, in wet or dry processes, including a magnetic plate, magnetic trap and magnetic grate - the latter being positioned within a transparent hopper and attached to a free-fall metal separator, as well as the Megastrength rare earth tube magnet.
The architects have worked closely with Buro Happold, renowned UK design team, to apply the principles of sustainability by exploiting passive environmental measures as well as innovative techniques including a shading roof structure, solar chimneys and earth tubes.
Earth tubes run from the oculus through the back of the berm to provide fresh air, supplemented by an evaporative cooler which acts as a sand filter and backup cooling method.
The final chapters address renewable energy options such as biomass, earth tubes and geothermal labyrinths, cogeneration, solar thermal, photovoltaic systems, wind power, and tidal energy, among others, as well as the details of various methods of energy storage.
The instrumentation in the building will not only collect data on the innovative systems, but it will monitor how fast the air moves through the earth tubes or the temperature of the water in the in-floor heating system to keep the building at a net-zero level.
Using such technologically-advanced features as thermal massing, energy blankets, root zone heating, and insulated glass for heat retention in addition to a computer-controlled shading system and an extensive passive ventilation system -- including 1,800 feet of underground earth tubes for cooling -- the Tropical Forest sets the standard for energy-efficient construction and operation.
