    COPPER TUBE HEADERSMade from heavy gauge seamless drawn copper

    tube, KeepRite designed headers lengthen coil life

    - provide necessary header flexibility to

    compansate for expansion and contraction during

    operation.

    Header flexibility also reduces coil core strains

    during start up. Further proof that KeepRite

    design means long life and top performance.

    WATER HEATING COILS

    MECHANICAL

    PRESSURE BONDKeepRite Mechanical

    Pressure Bond guarantees

    that each tube and fin collar

    make positive permanent

    metal to metal contact.

    No need for using low

    conductivity metals or alloys,

    FLANGED CASINGSDouble flanged galvanized

    steel casings on all

    KeepRite Water HeatingCoils provide greater

    strength - better support

    for easier coil stacking.

    Simplifies moving and handling operations.

    Top and bottom casing flanges are turned back to

    form two channel sections in a box shape.

    Provides maximum strength and durability.

    Standard casings are continuous galvanized steel.

    Copper and aluminum casings available.

    FULL FIN

    COLLARSEfficient KeepRite

    fin presses performmulti - stage operations

    to draw full fin collars

    with wide, smooth surfaces

    that completely cover coil

    tubes - actually form a tube within a tube for

    greater strength and maximum heat transfer.

    Lack of sharp collar edges make KeepRite

    Coils easier to clean - smoother KeepRite

    Collars retard lint and dirt accumulation.

    WATER HEATING COILS

    TYPE KWS COILSType KWS Coils are specifically designed andengineered to meet most applications requiring normalwater quantities and normal water pressure drop.Type KWS Coils are counterflow, single serpentinecircuited to deliver absolute maximum performance.With single serpentine coils every tube in the first row isfed.

    Type KWS Coils of two and four rows deep are fur-nished with the supply and return connections on thesame and of the coil. Intermediate drain headers areavailable to permit draining of coils which cannot beinstalled level.

    TYPE KWD COILSType KWD Coils are designed for use in applicationsthat require high water quantities and low water pressuredrop.KWD Coils are counterflow, double serpentine circuitedto maintain normal water velocities and low waterpressure drops. With double serpentine coils every tube inthe first and second rows are fed. KWD coils are 2 rowor 4 row. Four row coils have the supply and return con-nections on the same end of the coil. Intermediate drainheaders can be furnished to permit draining of coils thatcannot be installed level.

    TYPE KWH COILS

    Type KWH Coils are designed to produce highcapacity with limited water quantity. High capacity is

    obtained from the counterflow half serpentine water

    circuiting which gives higher water velocities.

    With half serpentine coils every other tube in the first

    row is fed. All Type KWH Coils, regardless of row

    depth, have both the supply and return connections on

    the same end of the coil. Intermediate drain headers are

    not available on KWH coils.

    TYPE B COILS

    Type B standard drainable single and double circuitreturn bend booster water heating coils are specificallymade for reheat zone applications. These coils will givehigh capacity with a normal water temperature drop. Inmany instances a two row booster coil will do a betterheating job that would require a three row standard coil.Single circuit one and two row and two circuit two rowcoils are available. The fin, tube and return bendconstruction is the same as for standard KWS coils, andcasing is designed for easy installation in confinedspaces.

    TABLE No. 1 COIL SIZES - NOMINAL FACE AREA SQ. FT.

    In addition to the Standard sizes listed above, KeepRite can furnish coils having an NTL up to 144 inches and a W dimension up to 72 inches.

    Type B coils available in sizes listed in BOLDonly.

    GENERAL INFORMATION

    DETERMINATION OF AIR MIXTURE TEMPERATURE

    SPECIFIED:

    Return air temperature = 51 OF cfm (return air) = 5100

    Fresh air temperature = 20 OF cfm (fresh air) = 1200

    SOLUTION:

    MIxed air temperature =cfm (return air) X (temp of return air) + cfm (fresh air) X (temp of fresh air)

    Total cfm mixture

    Mixed air temperature =5100 X 51 + 1200 X 20 = 260,100 + 24,000

    =284,100

    = 45.1OF

    6300 6300 6300

    Frequently return air at different temperatures or fresh air

    and return air are mixed before entering a heating coil. To

    determine the performance of a heating coil the

    mixture air temperature entering the coil is required.

    Determine mixture air temperature as follows:

    Desired face velocity must be assumed if not specified.

    For normal heating applications face velocities from 500 to800 fpm are recommended. Higher face velocities are

    used on some industrial and process installations.

    Occasionally lower face velocities are employed when the

    allowable air friction is extremely low.

    For hot water applications, coils are normally selected

    which have a tube length 2 to 3 times the W dimension.

    For best coil performance, the water flow rate should be

    between 3.0 and 6.0 gpm per feed. For normal

    applications it is recommended that 3 gpm per feed be

    assumed in the calculations, and that the coil most

    closely meeting this requirement be checked first. For the

    majority of applications this will be a KWH Coil. If a

    KWH exceeds the 3 gpm per feed, then check a KWS

    or KWD Coil.

    BS and BD2 Coils should be checked when the flow

    rate falls below 3 gpm per feed and the face dimensions

    fall within the booster coil sizes. If a low water pressure

    drop is desired, it is recommended that 3 gpm per feed

    be assumed in the calculations. In all selections the

    maximum allowable gpm per feed should be used to

    obtain the most economical coil.

    GPM PER FEED RECOMMENDATIONS

    RECOMMENDED FACE VELOCITY AND PRELIMINARY COIL SIZE SELECTION

    Square face dimension water coils are rarely selected

    because of the low water velocities that result. Coils ofseveral different dimensions are usally available to

    choose from. Select the most desirable. If the required

    face area is not listed in a size to fit the space available

    in Table 1 select a coil which will fit the space and

    divide the face area of this coil into the cfm to

    determine the coil face velocity.

    PROCESS APPLICATIONS AND COILS IN SERIES

    control is required, individual coils would be necessary.

    In calculating the temperature rise through a second coil,

    the leaving air temperature from the first is used as the

    entering air temperature to the second coil.

    Occasionally, it may be necessary or desirable to use two

    or more coils in series in order to obtain the final

    temperature required, although one coil of the proper

    depth is usally used on hot water installations. If row

    SERPENTINE

    The word serpentine has often been used in explaining or

    classifying circuiting of coils. A single serpentine coil has

    all the tubes in a row supplied in parallel. On a multi-row

    single serpentine coil the tubes of the second and

    subsequent rows are fed by return bends from the first

    row. A single serpentine coil with 8 tubes in the face all

    the tubes in the first two rows. A one-half serpentine

    coil has 1/2 as many circuits as there are tubes in the

    face. As a result the liquid passing through a 1/2

    serpentine coil, travels through two tubes in every row.

    KeepRite standard KWS one, two, three and four row

    coils are single serpentine. Standard KWD four row

    coils are double serpentine. KWH one, two, three and

    four row coils are 1/2 serpentine.

    4,800= 8.0 sg. ft

    face velocity 600

    2. BTUH REQUIRED

    Btuh = 1.09 M cfm X (lvg air temp - ent. air temp) = 1.09 X 4,800 X (120 - 70) = 261,600

    3. GALLONS PER MINUTE REQUIRED

    gpm =Btuh

    =261,600

    = 26.16 500 X water temp. drop 500 X 20

    4. BASE AIR TEMPERATURE RISE REQUIRED

    Base temp. rise =lvg air temp - ent air temp.

    Fe

    =120 - 70

    = 58.1 OF .86

    Where: .86 = Fecorr. fact for 190 OF ent water and 70 OF ent air

    temp. (Table 4, Page 23)

    5. PHYSICAL SIZE

    From Table 1, Page 3 select a coil that has a face area equal to, or greater than the minimum face area, and with face dimensions that will meet the application. For this example problem assume that a 24 X 48 Coil with 8.0 sq. ft. of face area is the best selection.

    6. APPRIXIMATE NUMBER OF FEEDS REQUIRED

    No. feeds =gpm

    =26.16

    = 8.7 gpm/feed 3

    A quick check of the Base Temp Rise tables indicates that at least a two row coil is required. Turn to the Coil Circuiting Tables (Table 5, Page 28). Under the 24 W dimension column, note that the 1, 2, 3 and 4 row. Type KWH high capacity coils have 8 feeds. Therefore, start selection using 8 feeds.

    7. GPM PER FEED

    gpm/feed =gpm

    =26.16

    = 3.27 no. feeds 8

    8. ROWS DEEP AND FIN SERIES

    From Table 3, Page 18 select a Type KWH Model 102 Coil.

    SOLUTION

    At 3 gpm/feed, 600 fpm and 48 NTL this coil has a base temp rise of 59.4OF. This meets the required base temp rise of 58.1 OF.

    9. ACTUAL BASE TEMPERATURE RISE

    Return to Table 3, Page 18 to the 600 fpm, 48 NTL, Type KWH, Model 102 section. at 3 gpm/feed - base temp. rise = 59.4 OF at 4 gpm/feed - base temp. rise = 62.0 OF

    By interpolation: at 3.27 gpm/feed - base temp. rise = 60.1 OF

    10. ACTUAL LEAVING AIR TEMPERATURE

    Actual temp. rise = base temp. rise X Fe

    = 60.1 X .86 = 51.7 OF

    Where: .86 = Fecorr. fact. for 190 OF ent. water and 70 OF ent. air

    temp. (Table 4, Page 23). Actual lvg air temp. = ent air temp. + temp. rise = 70 + 51.7 = 121.7 OF

    11. BTUH ACTUAL

    Btuh = 1.09 X cfm X (lvg air temp. - ent. air temp.) = 1.09 X 4,800 X (121.7 - 70) = 270,500

    12. WATER TEMPERATURE DROP ACTUAL

    Water temp. drop =Btuh

    =270,500

    = 20.7 OF 500 X gpm 500 X 26.16

    13. WATER PRESSURE DROP

    Water pressure drop = base water pressure drop X row-length corr. fact. = 2.00 X 1.31 = 2.62 ft. H

    2O

    Where: 2.00 = base water pressure drop for 3.27 gpm/feed and 2 rows (Figure 6, Page 29) 1.31 = row-length corr. fact. for 2 rows, Type KWH and 48 NT (Table6, Page 30)

    14. AIR PRESSURE DROP

    Air pressure drop = base pressure drop X Ffr

    = .19 X 1.16 = .22 in. H2O

    Where: .19 = base air pressure drop for 2 rows, 600 fpm (Figure 5, Page 28) 1.16 = 100 fin series corr fact. F

    fr(Figure 5, Page 28 inset)

    15. FINAL COIL SELECTION

    The final selection is a KWH 102 - 24 X 48 Coil. OF

    Table No. 2 NOTES1.Table base temperature rise values have been tabulated for 200 OF entering water and 60 OF entering air. At entering

    conditions other than the base use the Feentering conditions correction factors in Table 4 on Page 23.

    2.In general the table values have been tabulated for a range of 5 OF to 55 OF water temperature drop. Water

    temperature drop outside of the above range is perfectly satisfactory.3.Table values have been tabulated for a maximum water pressure drop of 20 feet of water.4. Interpolation between base temperature rise values is permissable for face velocities, face areas, and gpm per feeds. In the base temperature rise value for a higher face velocity, larger face area or smaller gpm per feed satisfies the required final air temperature condition, interpolation is not necessary unless the actual leaving air temperature is desired.5.For values not listed in the table, coils may be selected as shown on pages 24 and 25.

    ONE ROW COILS - 200 OF ENTERING WATER AND 60 OF ENTERING AIRTable No. 3

    KW HOT WATER COIL BASE TEMPERATURE RISE OF

    1. Table base temperature rise values have been tabulated for 200 OF entering water and 60 OF entering air. At entering conditions other than thebase use the Feentering conditions correction factors in Table 4 on Page 23.2. In general the table values have been tabulated for a range of 5 OF to 55 OF water temperature drop. Water temperature drop outside of theabove range is perfectly satisfactory.3. Table values have been tabulated for a maximum water pressure drop of 20 feet of water.4. Interpolation between base temperature rise values is permissable for face velocities, face areas, and gpm per feeds. In the basetemperature rise value for a higher face velocity, larger face area or smaller gpm per feed satisfies the required final air temperaturecondition, interpolation is not necessary unless the actual leaving air temperature is desired.5. For values not listed in the table, coils may be selected as shown on pages 24 and 25.
