Trenton Mechanical
Pressure Bond guarantees
that each tube and fin collar
make positive permanent

Double flanged galvanized
steel casings on all
Trenton Water Heating
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.

WATER HEATING COILS
TYPE “TWS” COILS
Type “TWS” Coils are specifically designed and
engineered to meet most applications requiring normal
water quantities and normal water pressure drop.
Type “TWS” Coils are counterflow, single serpentine
circuited to deliver absolute maximum performance.
With single serpentine coils every tube in the first row is
fed.
Type “TWS” Coils of two and four rows deep are
furnished with the supply and return connections on the
same and of the coil. Intermediate drain headers are
TYPE “TWD” COILS
Type “TWD” Coils are designed for use in applications that
require high water quantities and low water pressure drop.
“TWD” Coils are counterflow, double serpentine circuited
to maintain normal water velocities and low water
pressure drops. With double serpentine coils every tube in
the first and second rows are fed. “TWD” coils are 2 row or
4 row. Four row coils have the supply and return connections on the same end of the coil. Intermediate drain
headers can be furnished to permit draining of coils that
cannot be installed level.

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.
