Selection  
Procedure  
From Table PD-8, the output of 1 1/4  
steel, Series 52 element in a Type 12S  
enclosure is (looking under 180°F  
average water, 65°F entering air) 1060  
Btu/lineal foot at 3 ft/sec water velocity.  
Wall fin required:  
”
Ratings for 1 psi steam and 65°F  
entering air can be found on Tables  
PD-1 through PD-21. Ratings for other  
steam and air conditions can be  
obtained by multiplying the 1 psi —  
65°F capacity ratings by the proper  
steam correction factor from Table S-2.  
Hydronic/Steam Wall Fin  
Selection  
Hot Water Systems  
The capacity rating of wall fin in a hot  
water heating system depends on the  
difference between average water  
temperature and entering air  
temperature, and on the velocity at  
which water is circulated through the  
tube. The effect of water velocity on the  
capacity rating is appreciable (see Chart  
S-1) and should be taken into account  
when selecting wall fin. Following are  
example selections for hot water  
systems.  
21,739 Btu = 20.5 lineal feet.  
1060 Btu/ft  
Example 1  
Assume a steam system with 1 psi  
steam and 65°F entering air conditions.  
Also assume a 15,000 Btu heat loss for  
which a 1” copper-aluminum element 40  
fins/foot in a Type 10S enclosure is  
desired.  
Length Selection — Loop Systems  
Example 2  
If the unit in Example 1 above was part  
of a 100,000 Btu loop with a 20°F drop  
(across the entire loop) the water  
velocity through the loop would be 2.20  
ft/sec and the water velocity correction  
factor for all units on this loop would be  
approximately .987. For the unit being  
considered, the radiation would be  
selected to deliver 20,300  
Wall fin required:  
15,000 Btu = 13.9 lineal feet.  
1080 Btu/ft  
Hot Water Systems  
Example 1  
Example 2  
Assume a two-pipe system is being used  
with 180°F average water temperature,  
20°F temperature drop and 65°F entering  
air temperature. Assume a calculated  
heat loss of 20,000 Btu, for which one  
row of 1 1/4” steel element in a Type 12S  
enclosure is desired.  
Assume a steam system with 20 psi  
steam and 55°F entering air conditions.  
Also assume a 25,000 Btu heat loss for  
which 2 rows of 1 1/4” steel, Series 40  
element on 9 1/2” centers will be used  
without a cover. The capacity rating per  
lineal foot from Table PD-3 at 1 psi steam  
and 65°F entering air is 2120 Btu/ft.  
Multiplying this capacity rating by 1.52  
(steam correction factor from Table S-2)  
gives a rating of 3222 Btu/ft with 20 psi  
steam and 55°F entering air.  
20,000  
(
.987  
)
Btu at 3 ft/sec water velocity.  
Steam Systems — Selecting Wall Fin  
Lengths  
The capacity rating of wall fin in a steam  
heating system depends upon the  
difference between the steam  
temperature and the entering air  
temperature. For any steam system, to  
establish the lineal feet of wall fin  
required: divide the heat loss by the  
capacity rating per foot at the steam  
system and entering air conditions.  
From Chart S-1, reading from 20,000 Btu  
(under 20°F temperature drop) across to  
a 1 1/4” steel element and down, indicates  
a water velocity of approximately .45 ft/  
sec. The water velocity correction factor  
corresponding to .45 ft/sec is .920. The  
radiation is selected so that it would  
deliver  
Wall fin required: 25,000 Btu  
3222 Btu/ft  
= 8 lineal feet, 2 rows high.  
20,000 Btu (calculated heat loss)  
0.920 (velocity correction factor)  
or 21,739 Btu if the water velocity were 3  
ft/sec. It will then deliver the required  
20,000 Btu at the actual water velocity of  
.45 ft/sec.

Procedure  
Effect of Temperature Drop On  
Fin-Tube Ratings  
By use of the relationship,  
The heat output of a given wall fin unit  
will vary somewhat with different water  
velocities, all other conditions being  
equal. From Chart S-1, the water velocity  
can be found for a wall fin element of the  
particular tube size and gpm waterflow  
required. The velocity correction factor  
can be determined by using Chart S-1.  
GPM =  
BTU  
*500 x Water Temperature Drop  
The effect of temperature drop on heat  
output of a wall fin element can be  
readily determined. Select the heating  
element using average water  
temperature (entering water  
the waterflow rate for a wall fin unit of  
the required Btu and at a definite  
temperature drop, is easily calculated.  
(Many engineers use gallons per minute  
as the basis for selecting pipe sizes, since  
charts are set up on this basis in the  
ASHRAE Guide. Therefore, this would  
not be an extra step.)

condensation capacity. If the unit is  
installed at a different height than  
recommended, the following  
computation applies:  
Wall Fin Correction Factors Selection  
Two-Row Units, Serpentined (piped in  
series) — All water passes through both  
rows, so pressure drop per 100 feet (30.5  
m) of assembly is twice the pressure  
drop below the water velocity.  
1
Actual installed height is 19 7/32” (13 7/32”  
from Table PD-8 + 6” (152 mm) ).  
Interpolating from Table S-5, the heating  
effect factor is 1.065.  
Two-Row Units, Headered (piped in  
parallel) — Half the water flows through  
each row. The actual water velocity in  
each row is one-half the water velocity.  
The water velocity correction factor  
appears below the actual water velocity.  
Pressure drop will be the same for each  
row, so the drop per 100 (30.5 m) feet of  
assembly appears below the actual  
water velocity.

Recommended installed height is 13 7/32  
(from Table PD-8). From Table S-5, the  
heating effect is 1.075.

larger temperature drops.  
For water temperature drop other than  
size is dependent upon the capacity of  
the installed wall fin and the water  
temperature drop through the unit. Table  
S-6 gives the maximum installed  
20°F (-6.7C), the maximum capacity may  
be determined as follows:

*Tables based on 3 ft/sec. (.91 m/sec.)  
velocity should not exceed 8 ft/sec  
(2.4 m/sec.) due to pipe corrosion.  
The maximum recommended installed

dividing the maximum recommended

NOTE: Rating is Btu/hr/ft (Watts/meter) of finned length (for element dimensions see page 49). Hot water ratings determined by applying correction factor to steam ratings, are for  
water velocities of 3 ft/sec (.91 m/s) or greater. See page 9, Chart S-1 for correction factors for water velocities other than 3 ft/sec (.91 m/s). For definition of installed height and heating  
effect factors, see page 11. For heating ratings at other steam pressures and/or entering air temperatures, see page 10, Table S-2.

All two tier and 24F high ratings not IBR approved.  
Dimensions in bold indicate metric units.  
NOTE: Rating is Btu/hr/ft (Watts/meter) of finned length (for element dimensions see page 49). Hot water ratings determined by applying correction factor to steam ratings, are for  
water velocities of 3 ft/sec (.91 m/s) or greater. See page 9, Chart S-1 for correction factors for water velocities other than 3 ft/sec (.91 m/s). For definition of installed height and heating  
effect factors, see page 11. For heating ratings at other steam pressures and/or entering air temperatures, see page 10, Table S-2.

All two tier and 24T high ratings not IBR approved.  
Dimensions in bold indicate metric units.  
NOTE: Rating is Btu/hr/ft (Watts/meter) of finned length (for element dimensions see page 49). Hot water ratings determined by applying correction factor to steam ratings, are for  
water velocities of 3 ft/sec (.91 m/s) or greater. See page 9, Chart S-1 for correction factors for water velocities other than 3 ft/sec (.91 m/s). For definition of installed height and heating  
effect factors, see page 11. For heating ratings at other steam pressures and/or entering air temperatures, see page 10, Table S-2.

All two tier and 24TA high ratings not IBR approved.  
Dimensions in bold indicate metric units.  
NOTE: Rating is Btu/hr/ft (Watts/meter) of finned length (for element dimensions see page 49). Hot water ratings determined by applying correction factor to steam ratings, are for  
water velocities of 3 ft/sec (.91 m/s) or greater. See page 9, Chart S-1 for correction factors for water velocities other than 3 ft/sec (.91 m/s). For definition of installed height and heating  
effect factors, see page 11. For heating ratings at other steam pressures and/or entering air temperatures, see page 10, Table S-2.

NOTE: Rating is Btu/hr/ft (Watts/meter) of finned length (for element dimensions see page 49). Hot water ratings determined by applying correction factor to steam ratings, are for  
water velocities of 3 ft/sec (.91 m/s) or greater. See page 9, Chart S-1 for correction factors for water velocities other than 3 ft/sec (.91 m/s). For definition of installed height and heating  
effect factors, see page 11. For heating ratings at other steam pressures and/or entering air temperatures, see page 10, Table S-2.

Element, Enclosure And Cover Length —  
General  
Enclosures  
With elements selected to meet capacity  
needs, assume enclosures will be  
selected to cover elements and piping  
connections required. Since enclosures  
are available in 6” (0.15 m) increments,  
19’ (2.7 m) will be used to cover the  
above assembly. Two 6 1/2’ (2 m) and one  
6’ (1.8 m) enclosure, 6 brackets (2 per  
enclosure or 1 every three feet (.9m) will  
be required. The overall length, including  
right and left end panels, is 19’ (2.7 m) +  
2” (.05 m) = 19’ 2” (2.75 m).  
The over-all length of an enclosure or  
cover, or of several joined together, is the  
same as the ordering length. Over- all  
length when an end panel is used is 1”  
(25 mm) longer than the ordering length.  
Over-all length when right and left end  
panels are used is 2” (51 mm) longer  
than the ordering length.  
For wall-to-wall installations, use total  
length to the nearest 6” (152 mm)  
increment below the actual wall-to-wall  
measurement. Enclosure extensions  
telescope up to 4” (102 mm) to meet the  
wall. Access panels (6” (152 mm) or 12”  
(305 mm)) and 12” (305 mm) access  
panels with 5” x 6” (127 x 152 mm) size  
access door centered, provide easy  
access to valves and fittings and can be  
used for 6” (152 mm) or 12” (305 mm)  
runs to the wall.  
Wall-To-Wall Installations  
To make a wall-to-wall installation with a  
total length of 20’ 4 1/2” (6.2 m), the  
enclosure selection would change. In  
addition to 20’ (6.1 m) of enclosure, two  
5” (127 mm) enclosure extensions  
would be required to accommodate the  
odd 4 1/2” (114 mm) dimension. Four 5’  
(1.5 m) enclosures and eight enclosure  
brackets would be needed.  
3
/4” CA (19 mm) copper-aluminum  
elements are available in lengths of 1’  
(.305 m) through 8’ (2.4 m ) in 6” (0.15 m)  
increments. 1 1/4” (32 mm) steel or 1” (25  
mm) and 1 1/4” (32 mm) copper-  
Type X Covers And Type E Covers  
Type X or Type E covers are normally  
specified to cover only the heating  
elements. For an 18’ (5.5 m) of element,  
three 6’ (1.8 m) lengths of Type X or Type  
E covers would be necessary. Type X  
and Type E covers are supported at the  
back and bottom front by wall brackets.  
aluminum elements are available in  
lengths of 1’ (.305 m) through 12’ (3.7 m)  
in 6” (0.15 m) increments. Cabinets are  
available in lengths of 2’ (.61 m) through  
8’ (2.4 m) in 6” (0.15 m) increments. Type  
X covers in lengths of 2’ (.61 m) through  
8’ (2.4 m) in 6” (0.15 m) increments, 24”  
(610 mm) high cabinets in lengths of 2’  
(.61 m) through 8’ (2.4 m) in 6” (0.15 m)  
increments.  
Elements  
Assume an 18’ (5.5 m) of 1 1/4” (32 mm)  
steel, Series 52 element is required for  
capacity needed. Unions will be used for  
joining sections of the element along  
with supply and return connections at  
the ends. Two 9’ (2.7 m) lengths of  
element will be required, with one joint  
between them. Total length of the  
installed assembly will be: 18’ (5.5 m)  
(element length) + union joint + lengths  
of supply and return connections.

Mullion channels are used on panel walls  
or curtain walls where the wall studs (or  
mullions) are more than four feet apart  
and project into the room. Because of the  
weight of the wall fin unit and the lack of  
strength in the wall construction, mullion  
channels are used to provide support  
between the wall studs. The channels fill  
the space between the wall fin cabinet  
and the panel wall or curtain wall.

Features and  
Benefits  
Security Wall Fin  
The Trane hydronic security wall fin  
enclosures have been designed for  
natural convection in slope top (Type S)  
and flat top (Type F) configurations in 12”  
(305 mm) and 18” (457 mm) heights with  
a depth of 5 5/16” (135 mm), primarily for  
use in maximum security applications  
such as prisons and mental institutions.  
Security wall fin is also recommended  
for use in schools, dormitories, nursing  
homes, athletic facilities, day care  
centers, detention homes, psychiatric  
centers, public type buildings and other  
heavy abuse areas.  
Wrap-Around Design  
Each enclosure’s top/front/bottom panel  
is of one-piece full wrap-around design  
for complete engagement with the wall  
to help prevent access to the inside of the  
unit. All enclosure panels are  
1
manufactured with /8” (3 mm) diameter  
3
holes on /16” (5 mm) staggered centers  
for a partial perforated (inlet and outlet)  
panel with internal interlocking slip joints.  
Optional fully-perforated enclosures of  
the entire panel are available with an  
intermediate overlapping wall sleeve  
with pre- punched fastener holes for  
panel-to- panel alignment and fastening.  
Vandal-Resistant  
The security enclosure offers vandal-  
resistant construction.  
Heating elements or return and supply  
piping are secured to the wall with wall  
type element brackets manufactured of  
14-gauge (1.9 mm thickness) galvaneal  
Steel with channel-formed edges for  
rigidity. Each wall bracket is furnished  
with galvanized element cradles and  
nylon inserts with snap-in rust-resistant  
nickel-chromium plated ball bearings for  
silent glide operation of the heating  
element.  
Simple installation, made of 14-gauge  
(1.9 mm thickness) steel, and durability  
are made possible by a continuous  
partial back plate/mounting strip. A full  
back plate/mounting strip manufactured  
from 14-gauge (1.9 mm thickness) steel  
is optional.  
Tamper resistant helps prevent vandals  
from concealing undesirable or  
hazardous items within the enclosure.  
Clean, Even Heat  
Durable Construction  
Only the air within the room is  
recirculated, so walls and furnishings  
stay cleaner.  
A variety of heating elements is available  
along with a complete line of  
accessories. Manufactured from 14-  
gauge (1.9 mm thickness) steel for  
strength, these accessories allow for  
wall-to-wall installation that is  
architecturally compatible with most  
interior designs.  
A baked-on commercial primer paint is  
standard.  
Rigid front panels are constructed of 14-  
gauge (1.9 mm thickness) or 12- gauge  
(2.7 mm thickness) steel.  
Attractive  
Available with six optional baked-on  
enamel color finishes chosen from  
Trane’s Color Selection Chart UNT-S-10.

Features and  
Benefits  
Model 11S  
Light Commercial Slope Top  
Wall Fin Enclosure  
The Trane hydronic light commercial  
slope top 11S wall fin line has been  
designed for natural convection to fill a  
void between less costly residential and  
commercial baseboard and the bigger  
and more expensive commercial wall fin  
enclosures and elements.  
11S is a clean, reliable hydronic heat  
perimeter heating system that can be  
used as an economical primary or  
secondary heat source. It also serves as  
an effective draft barrier near cold walls  
and windows.  
Because of its ease of installation, rugged  
construction and styling, 11S wall fin is  
especially suited for use in commercial,  
industrial and institutional applications.  
Typical examples include offices,  
schools, hospitals, dormitories, nursing  
homes, churches, transportation  
terminals and housing projects.  
A wide variety of heating elements is  
available, along with a complete line of  
accessories for wall-to-wall installation  
that is architecturally compatible with  
any interior design. Other features and  
benefits include:  
Simple installation with a rugged  
•
mounting strip allows bracket  
placement.  
Rigid front panels constructed of  
•
18-gauge or 16-gauge steel.  
Quiet operation.  
•
Clean, even heat — only the air within  
•
the room is recirculated — walls and  
furnishings stay cleaner.  
Pencil-proof louvered air opening —  
•
helps prevent trash from accumulating  
on the heating element.  
Durable finish — all enclosures and  
•
accessories are cleaned and chemically  
phosphatized before painting.  
Labor-saving rod hangers —  
•
suspended from the top of the  
enclosure bracket, they allow full  
expansion of the element. There are no  
bolts to fasten.  
No visible fasteners.
