Coils 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.
COPPER TUBE HEADERS
Made from heavy gauge seamless drawn copper
tube, Trenton 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 Trenton
design means long life and top performance.
FULL FIN
COLLARS
Efficient Trenton
fin presses perform
multi - 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 Trenton Coils
easier to clean - smoother Trenton Collars
retard lint and dirt accumulation.

TYPE “TWH” COILS
Type “TWH” Coils are designed to produce high
capacity 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 “TWH” 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 “TWH” coils.
TYPE “TB” COILS
Type “TB” standard drainable single and double circuit
return bend booster water heating coils are specifically
made for reheat zone applications. These coils will give
high capacity with a normal water temperature drop. In
many instances a two row booster coil will do a better
heating job that would require a three row standard coil.
Single circuit one and two row and two circuit two row
coils are available. The fin, tube and return bend
construction is the same as for standard “TWS” coils, and
casing is designed for easy installation in confined
spaces.

GENERAL INFORMATION
DETERMINATION OF AIR MIXTURE TEMPERATURE
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
SPECIFIED:
Return air temperature = 51 OF cfm (return air) = 5100
Fresh air temperature = 20 OF cfm (fresh air) = 1200
SOLUTION:
MIxed air temperature =
Total cfm mixture
Mixed air temperature =
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 “TWH” Coil. If a
“TWH” exceeds the 3 gpm per feed, then check a “TWS’
or “TWD” Coil.
cfm (return air) X (temp of return air) + cfm (fresh air) X (temp of fresh air)
5100 X 51 + 1200 X 20 = 260,100 + 24,000 = 284,100

GPM PER FEED RECOMMENDATIONS
mixture air temperature entering the coil is required.
Determine mixture air temperature as follows:
6300
“TBS” and “TBD2” 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.
= 45.1OF
RECOMMENDED FACE VELOCITY AND PRELIMINARY COIL SIZE SELECTION
Desired face velocity must be assumed if not specified.
For normal heating applications face velocities from 500 to
800 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.
PROCESS APPLICATIONS AND COILS IN SERIES
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
Square face dimension water coils are rarely selected
because of the low water velocities that result. Coils of
several 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.
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.
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.
Trenton standard “TWS” one, two, three and four row coils
are single serpentine. Standard “TWD” four row
coils are double serpentine. “TWH” one, two, three and
four row coils are 1/2 serpentine.

CONVERSION OF AIR VOLUME TO STANDARD AIR
When the specified air volume (cfm) is given at any temperature other than 70 OF or at any altitude
other than sea level, these charts should be used for correction before using the following capacity

1. 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 Fe entering 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.

1. 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 F
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.

DETAILED COIL SELECTION
FOR SELECTING COILS WITH VALUES NOT LISTED IN TABLES 2 AND 3
GPM PER FEED RECOMMENDATIONS
For best coil performance, the water flow rate should be between
1.5 and 4.0 GPM per feed. 3 GPM per feed should be assumed in
calculations and the type of coil most closely meeting this
EXAMPLE PROBLEM No. 1
(Showing Use of Heat Transfer Curves Table No. 3)
GIVEN:
CFM (Std. Air).................................................................................................... 4,800
Maximum Face Velocity (FPM).......................................................................... 600
Entering Air Temperature.................................................................................70 OF
Required Final Air Temperature...................................................................120 OF
Entering Water Temperature........................................................................ 190 OF
Desired Water Temperature Drop..................................................................20 OF
Maximum Water Pressure drop (Ft H2O)..........................................................4.0
Maximum Air Pressure drop (IN, H2 O)............................................................0.26

2. PHYSICAL SIZE OF COIL
From Table 1, Page 3 select a 24” X 48”
(Other sizes may be selected to furnish the same face
area).
3. BTUH - REQUIRED
Btuh = 1.09 X cfm X (lvg air temp. - ent air temp.)
= 1.09 X 4800 X (120 - 70) = 261,600
4. GALLONS PER MINUTE REQUIRED
gpm =
500 X Water temp. drop
5. APPROX. No. OF FEEDS REQUIRED

Feeds =
gpm/feed
6. ACTUAL GPM PER FEED
From table 5, page 27 a 24” W. dimension indicates 8
feeds for “TWH” coils.
Actual GPM feed =
This is satisfactory.
7. HEAT TRANSFER FACTOR “U”
From Fig. 3, Page 25 for Series 80 fin spacing, 3.27 gpm/
feed 600 fpm face velocity, note the “U” factor as 175.
8. MEAN EFFECTIVE TEMPERATURE DIFFERENCE
For counterflow, the MED is as follows:
Leav water temp. Ent water temp. = 170 190
Ent air temp. Leav air temp. = 70 120

D1 = 100 D2 = 70
SOLUTION
Refer to figure 4, Pages 26, 27 and determine MED as 83.9
NOTE: Trenton coils are normally selected and
constructed for counterflow unless specifically stated that
they are for parallel air-to-water heat transfer.
For parallel flow D1 and D2 are selected dy
9. ROWS DEEP REQUIRED
Rows Deep =
face area X U X MED 8.0 X 174 X 83.9
A two row Series 80 coil is not large enough. A Series 100 coil
can be checked by applying the fin connection factor in Fig. 3
to the base “U” factor curve = 175 X 1.16 = 203
Series 100 Row Depth =
This selection would be suitable and therefore a model KWH
102-24” X 48” coil is required.
10.WATER PRESSURE DROP
= 2.62 feet of water
11. AIR FRICTION
The air side pressure drop for a KWH 102 - 24 X 48” coil at
600 fpm is .19 X 1.16 fin correction factor (See Figure 5,
Page 28)
= .22 inches of water.
requirement be checked first, TWS coils will meet the largest number
of requirements; if a TWS coil doesn’t give the desired GPM per feed
rate TWH, TBS, TBD and TWD coils should then be checked.

EXAMPLE CALCULATION
The base pressure drop at 1.5 GPM/Feed is .50 feet of
water, read directly from Figure 6. The proper correction
factor is then selected from Table 6 or 7 and multiplied
times the base drop. In this instance the row-length
correction factor of .78 (for TWS 82 - 27 X 60) is
obtained from Table 6. The pressure drop of the
W82 - 27 X 60 coil for this application is .50 X .78 = .39 ft.
of water.

ENGINEERING SPECIFICATIONS
WATER HEATING COILS
FURNISH and install as shown on the plans and as
described in the tabulated specifications Trenton
non-ferrous Water Coils of extended surface, staggered
tube, rippled-corugated plate fin type.
WATER HEADERS shall be of non-ferrous materials using
seamless copper tubing vent and drain connections shall
be provided at the highest and lowest points to assure
proper venting and draining.
PRIMARY SURFACE shall be round, 5/8” O.D. copper tubing
brazed into intruded header spigots, using copper brazing
alloys. Tubes shall be staggered in the direction of air flow.
SECONDARY SURF ACE shall consist of rippled-corrugated
aluminum plate fins for higher capacity and strength. Flat
plate fins will not be acceptable as they are less efficient.
Fins shall have full drawn collars to provide a continuous
surface cover over the entire tube, without sharp edges
which accumulate lint and dirt. Bare copper tube shall not
be visible between fins and fins shall have no openings
punched in them to accumulate lint and dirt. Tubes shall be
expanded into the fins to provide a continuous primary to
secondary compression bond over the entire finned length,
for maximum heat transfer rates.

CASINGS shall be constructed of continuous galvanized steel
with 3/8” diameter bolt holes for mounting on 3” centers. Coil
side plates shall also be of continuous galvanized steel of
reinforced flange type for greater strength and ease of
stacking coils in banks.
COILS shall have connections provided for universal right or
left hand air flow applications. Coils shall be circuited to
provide the maximum mean effective temperature difference
for maximum heat transfer rates. The use of internal restrictive devices to obtain turbulent flow will not be acceptable
since they prevent complete draining of the coil.
TUBES shall be on 1 1/2” centers and tubes may not be
omitted from the tube pattern. Coils must contain at least 1.13
sq. ft. of primary surface area per sq. ft. of face area, per row
deep. Complete coil core shall be tested with 300 pounds of
air pressure under warm water and guaranteed for 200 psig
working pressures. Individual tube tests and core tests
before installation of header is not considered satisfactory.
Hydrostatic tests alone will not be acceptable. All coils shall
be completely drainable for the service specified when
properly installed.
