Ecology tanks are designed to capture fluids in a variety of different applications. Parker has fielded designs for fuel, oil, and hydraulic systems. The fuel ecology tanks capture fuel during engine shutdown and return the oil to the fuel tanks during the start of the engine. Oil and hydraulic ecology tanks capture small amounts of oil during flight that can be returned to the tank or drained before the next flight.
