To Our Valued Customers:

Welcome to American Industrial Heat Transfer, Inc. your number one source for high quality heat transfer products. Following is our new 2019-2020 highly defined products catalog that is intended to provide valuable information regarding engineering specifications, selection procedures, application assistance, installation instructions, terms and conditions, and much more. Throughout its thirty-year history, American Industrial has consistently provided customers with high quality heat exchangers, unmatched service, and low prices. Our commitment to being a leading manufacturer is reflected by our investments in a state of the art manufacturing facility, cutting edge CNC manufacturing machinery, custom computer enterprise technology, skilled engineering services, global purchasing alliances, and strong distribution channels. American Industrial manufactures ninety-five percent of all components used in its products at our facility in LaCrosse, Virginia. Finished components from the smallest to the largest are meticulously fabricated with precision CNC equipment and skilled craftsmen. For those reasons American Industrial is a true manufacturer with the ability to control design and quality allowing us to deliver products in far shorter period than the competition. The 2019-2020 products catalog has several new additions, adding popular items to our regular standard product offering. American Industrial's standard catalog products account for about fifty percent of total manufacturing capacity, the remaining capacity is available for use to manufacture custom engineered heat exchangers or additional demand. It is recommended to review the catalog in order to gain understanding of the various product types, their differences from one brochure to the other specifically in dimensions, materials, capabilities, and sizes. By reviewing the catalog prior to selection it will make it easier to understand the information needed to assure proper heat exchanger selection and usage and minimize the time and effort spent during the process.

Warm Regards, Ghasem Sariri Ghasem Sariri President American Industrial Heat Transfer, Inc.

AB, SAE, STS, & EAB Series overview

AB Series Fixed tube construction heat exchangers with NPT connections. Made of brass with copper cooling tubes and cast iron end bonnets. Standard sizes from 2" through 8" diameters, and from 1.4 to 308 sq.ft. Standard one, two, and four pass models are available. Options include 90/10 copper nickel and 316 stainless steel cooling tubes, bronze bonnets and zinc anodes. Can be customized to fit your requirements. Optional 10” diameter units in brass are available upon request.

AB, SAE, STS, & EAB Series selection

STEP 1: Calculate the heat load The heat load in BTU/HR or (Q) can be derived by using several methods. To simplify things, we will consider general specifications for hydraulic system oils and other fluids that are commonly used with shell & tube heat exchangers.

Kw = Kilowatt (watts x 1000) T in = Hot fluid entering temperature in °F T out = Hot fluid exiting temperature in °F t in = Cold fluid temperature entering in °F t out = Cold fluid temperature exiting in °F Q = BTU / HR

Terms GPM = Gallons Per Minute CN = Constant Number for a given fluid  T = Temperature differential across the potential PSI = Pounds per Square Inch (pressure) of the operating side of the system MHP = Horsepower of the electric motor driving the hydraulic pump

For example purposes, a hydraulic system has a 125 HP (93Kw) electric motor installed coupled to a pump that produces a flow of 80 GPM @ 2500 PSIG. The temperature differential of the oil entering the pump vs exiting the system is about 5.3°F. Even though our return line pressure operates below 100 psi, we must calculate the system heat load potential (Q) based upon the prime movers (pump) capability. We can use one of the following equations to accomplish this: To derive the required heat load (Q) to be removed by the heat exchanger, apply ONE of the following. Note: The calculated heat loads may dif- fer slightly from one formula to the next. This is due to assumptions made when estimating heat removal requirements. The factor (v) represents the percentage of the overall input energy to be rejected by the heat exchanger. The (v) factor is generally about 30% for most hydraulic systems, however it can range from 20%-70% depending upon the installed system components and heat being generated (ie. servo valves, proportional valves, etc…will increase the percentage required).

Constant for a given fluid ( CN )

F ormula a ) Q = GPM x CN x actual  T b ) Q = [ (PSI x GPM) / 1714 ] x ( v ) x 2545 c ) Q = MHP x ( v ) x 2545

E xample a ) Q =80 x 210 x 5.3°F = 89,040 btu / hr b ) Q =[(2500x80)/1714] x .30 x 2545 = 89,090 btu / hr c ) Q =125 x .30 x 2545 = 95,347 btu / hr

1) Oil .............................. CN = 210 2) Water.......................... CN = 500 3) 50% E. Glycol............ CN = 450

d ) Q = Kw to be removed x 3415 e ) Q = HP to be removed x 2545

d ) Q =28 x 3415 = 95,620 btu / hr e ) Q =37.5 x 2545 = 95,437 btu / hr

STEP 2: Calculate the Mean Temperature Difference

When calculating the MTD you will be required to choose a liquid flow rate to derive the Cold Side  T. If your water flow is unknown you may need to assume a number based on what is available. As a normal rule of thumb, for oil to water cooling a 2:1 oil to water ratio is used. For applications of water to water or 50 % Ethylene Glycol to water, a 1:1 ratio is common.

F ormula

E xample  T = 89,090 BTU/hr ( from step 1,example b ) = 5.3°F =  T Rejected 210 CN x 80GPM

T in = Ho t Fluid entering temperature in degrees F T out = Hot Fluid exiting temperature in degrees F t in = Cold Fluid entering temperature in degrees F t out = Cold Fluid exiting temperature in degrees F T out - t in S [smaller temperature difference] S = L [larger temperature difference] = L T in - t out ( )

T in = 125.3 °F T out = 120.0 °F t in = 70.0 °F t out = 74.5 °F

120.0°F -70.0°F = 50.0°F = 50.0°F = .984

125.3°F -74.5°F = 50.8°F

50.8°F

STEP 3: Calculate Log Mean Temperature Difference (LMTD)

To calculate the LMTD please use the following method;

L = Larger temperature difference from step 2. M = S/L number ( located in table A ). LMTD i = L x M

LMTD i = 50.8 x .992 ( from table A ) = 50.39

To correct the LMTD i for a multipass heat exchangers calculate R & K as follows:

F ormula

E xample

T in - T out t out - t in

125.3°F - 120°F 74.5°F - 70°F

5.3°F 4.5°F

Locate the correction factor CF B ( from table B ) LMTD c =LMTD i x CF B LMTD c = 50.39 x 1 = 50.39

R =

{1.17=R}

R =

t out - t in T in - t in

74.5°F - 70°F 124.5°F - 70°F

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 = 80 GPM = Series Required from Table E = 1200 Series Baffle Spacing from Table E = C ba ffle Water Flow Rate = 40 GPM = Passes required in 1200 series = 4 (FP) 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.

Instructions

The selection chart provided contains an array of popular sizes for quick sizing. It does not provide curves for all models available. Refer to page 4 & 5 for detailed calculation information. Computer selection data sheets for standard or special models are avail- able through the engineering department of American Industrial. To use the followings graphs correctly, refer to the instruction notes "1-5". 1) HP Curves are based upon a 40°F approach temperature; for example: oil leaving a cooler at 125°F, using 85°F cooling water (125°F – 85°F = 40°F ). 2) The oil to water ratio of 1:1 or 2:1 means that for every 1 gallon of oil circulated, a minimum of 1 or 1/2 gallon (respectively) of 85°F water must be circulated to match the curve results.

3) OIL PRESSURE DROP CODING:  = 5 psi;  = 10 psi;  = 20 psi;  = 50psi. Curves that have no pressure drop code symbols indicate that the oil pressure drop is less than 5 psi for the flow rate shown. 4) Pressure Drop is based upon oil with an average viscosity of 100 SSU. If the average oil viscosity is other than 100 SSU, then multiply the indicated Pressure Drop by the corresponding value from corrections table A.

5) Corrections for approach temperature and oil viscosity are as follows:
