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.

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.

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.
