5. An air-cooled heat exchanger system, comprising:
-
a tube bundle having an air inlet side and an air outlet side; a fan, wherein the fan is disposed on the air outlet side of the tube bundle for an induced-draft heat exchanger system, and wherein the fan is disposed on the air inlet side of the tube bundle for a forced-draft heat exchanger system; and a pre-cooler disposed on the air inlet side of the tube bundle, wherein the pre-cooler is configured to lower an ambient air temperature to an inlet temperature when a cooling medium is circulated through the pre-cooler, and wherein the air inlet temperature is within a preselected temperature tolerance. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. A method of removing heat from a process fluid, comprising:
-
circulating a pre-cooler medium through a pre-cooler disposed on the air inlet side of an air-cooled heat exchanger tube bundle; circulating the process fluid through the air-cooled heat exchanger tube bundle; passing air to the pre-cooler at a first temperature; changing the temperature of the air to create a conditioned air; passing the conditioned air through the air inlet side of the air-cooled heat exchanger tube bundle; and removing heat from the process fluid by heat exchange with the conditioned air. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
