SRCS Series selection
STEP 5: Selection a) From table E choose the correct series size, baffle spacing, and number of passes that best fits your flow rates for both shell and tube side. Note that the tables suggest minimum and maximum information. Try to stay within the 20-80 percent range of the indicated numbers. Example Oil Flow Rate = 600 GPM = Series Required from Table E = 2400 Series Baffle Spacing from Table E = 18 baffle Water Flow Rate = 300 GPM = Passes required in 2000 series = TP b) From table D choose the heat exchanger model size based upon the sq.ft. or surface area in the series size that will accommodate your flow rate. Example Required Area = 300.4 sq.ft Closest model required based upon sq.ft. & series = SRCS-2484-18-6-TP If you require a computer generated data sheet for the application, or if the information that you are trying to apply does not match the corre- sponding information, please contact our engineering services department for further assistance.
