a storage tank is used to store a large quantity of pseudoplastic deicing fluid . the fluid is stored at an ambient storage temperature . the storage tank has an outlet which is preferably a valve located on the floor of the tank . a heater is provided to rapidly heat only a portion of the fluid in the tank to a required delivery temperature estimated at between 160 and 180 degrees fahrenheit . once a portion of the fluid is heated to the appropriate temperature , the valve is opened and the heated fluid is delivered out of the tank through the valve . heat is transferred to the fluid in a heating area creating a predetermined dynamic temperature pattern within the fluid when the outlet is in the closed position and a predetermined steady state temperature pattern within the fluid when the outlet is in the open position . the predetermined steady state temperature pattern is defined by the fluid flowing through the outlet being at the delivery temperature , the fluid flowing through a delivery area being heated to the delivery temperature , and the fluid flowing from the stored area to the delivery area being heated to approach the delivery temperature according to its relative distance from the outlet .
