Abstract
A delivery system for transferring a delivery fluid from a delivery tank to a customer tank while maintaining a predetermined vessel pressure in the delivery tank, including a pump assembly pumping fluid from the delivery tank and a piping system passing the pumped fluid to the customer tank. A diverter diverts a slip stream portion of the pumped delivery fluid and a heat exchanger assembly selectively heats or cools the slip stream portion for return to the delivery tank. A sensor monitors a selected condition in the delivery tank and a controller responds to the sensor to control the amount and thermal condition of the slip stream returned to the delivery tank.
