  26. 26. Geotech Solar Sipper<br />The Geotech Solar Sipper is a solar powered remediation system, designed for remote applications where electrical power is either not available or not economically feasible to provide. The compact, easy to install features make this unit an industry favorite!<br />Unlike other solar powered pumping systems, which use a standard bladder pump operated by an air compressor, the Solar Sipper uses a unique vacuum/pressure canister pump to recover hydrocarbons through a floating oleophilic/ hydrophobic intake filter. When the pump canister is filled, the pump reverses, pressurizes the system and pumps the recovered fluid to the surface and into a storage vessel.<br />The Geotech Solar Sipper can effectively extract fluids from depths to 180 feet below ground surface and recover viscous hydrocarbons such as 90 weight oil when a fixed intake is utilized.<br />
