The Clean-Line Appearance of the Model S Unit Heater

What’s more, the Model P can be stored
standing on end. This means several
units can be loaded on a single skid for
moving from one point to another. Trane
maintains a complete stock of both
Model P and S units that are available to
ship anywhere in the United States.

Y et, the benefits of this compact design
go beyond ease of installation. They
continue with attractive styling. The
Model S unit’s simple, clean-line
symmetry and the Model P unit’s classic
modern shape enhance any industrial
facility.

Two Units in One – the Versatile Model P

The T rane Model P can be quic kly field
converted from standard to low final
temperature PL design simply by
removing the unit’s patented knockout
air ports. This unique two-in-one design
allows the stocking wholesaler to cut
inventories in half and still meet most
customer application requirements.

T rane propeller unit heaters feature the
largest selection of standard sizes from
any line in the industry . In fact, vertical
Model P and horizontal Model S unit
heaters provide enough ‘of f-the-shelf’
selections to fit almost any application.
The versatile two-in-one Model P is
available in 15 sizes with capacities from
41 .3 MBh to 705.6 MBh while the
companion standard and bypass Model

The Space-Saving Model S

The Model S features attractive,
functional styling in a space-saving,
compact design.
In addition, T rane of fers an exclusive
bypass Model S design to meet low final
temperature, high cfm requirements. This
design uses a modified coil which allows
some of the air to flow over the top of the
coil without being heated. This cooler
band of air prevents the heated air from
rising so warm air throw is increased
while efficiency is improved.

S is available in 29 sizes with the
capacities from 17.4 MBh up to 404 MBh.
Both are designed for durability,
attractiveness and compactness. These
features combined with economical
operation, give strategically sized T rane
unit heaters an edge unmatched by any
other manufacturer.

Put Heat Where It’s Needed

Exclusive louver fin diffusers featured on
T rane unit heaters put heat where it’s
needed.

Patented Trane louver cone diffusers allow
directional flexibility of heated air.

Trane Model S features louve red disc har ge as
standard.

These patented T rane dif fusers provide
an unlimited combination of air diffusion
patterns as well as greater air throw
distance. In fact, when the louver cone
diffuser is added to the Model P, up to 45
percent greater air throw distance is
possible.
On Model S units, the combination of
horizontal louver blades and patented
vertical diffuser fins provide four­directional control of air delivery.
Optional low cost louver fin diffusers can
be adjusted to provide up to 25 percent
more air throw.

The Model S Coil

The Model S unit heater features a
unique single tube serpentine coil. This
compact, efficient coil has piping
connections at the back for added space
savings, convenience and appearance.
Model S single circuit coils use threaded
connectors at the back of the unit.

The Model P Motor

The Model P motor is mounted below
the top panel inside the heater casing.
This reduces unit height and permits the
unit to be installed closer to the ceiling
for added headroom.

Compact Design

T rane designed Model S and P propeller
unit heaters for easy installation and low
maintenance. The Trane Sigma-Flo
design allows coil size to be reduced
while maintaining high capacity
performance equal to larger flat-fin coils.
Reduced size and weight makes T rane
unit heaters easy to handle and install.

Rectangular Draw -Thr u Coils

The Model P draw-thru coils use short
lengths of steel pipe threaded for supply
and return connections. These features
make piping connections much easier
for the installer.

General Rules

In locating or spotting Trane Propeller
Unit Heaters – either the Model S
Horizontal or Model P Projection Unit
Heater – the following general rules
should be considered.
1 . Spot units at points of greatest heat
loss. Blanket outside doorways
effectively and provide ample coverage
for exposed window areas.

2. Units, especially in the case of the
Model S Horizontal Unit Heater , should
be arranged to blow toward or along
exposed walls, preferably striking the
wall at a slight angle so that the heated
air exerts a wiping effect along the w all.
Balance of units required to supply Btu
requirements should be spaced
strategically in balance of the area.

3. Unit heaters should be arranged to
blow into open spaces such as aisles and
not directly at any worker. An exception
to this rule involves the use of the Model
P Unit Heater equipped with the Louver
Cone Diffuser . This combination can be
used effectively over closely spaced bins
or machines without regard for open
space. But not even the Model P Unit
Heater with Louver Cone Diffuser should
be in such close proximity to the workers
to cause discomfort.

4. The T rane solid-state speed control will
provide maximum capacity flexibility and
quieter operation. Note that this speed
controller is available only on selected
models.

5. Mounting heights and distance of
throw recommendations as given
elsewhere in this catalog should be
carefully observed.

6. In the case of Model P Units, they
should be spotted so that they will most
effectively prevent stratification of
excessively warm air at the ceiling. By
carefully observing this rule, this type of
unit may be used between seasons to
tap waste heat at the ceiling and drive it
down to occupied zones, thereby
eliminating the need for added heat on
the system.

7. Do not spot units close to any
obstruction that will impede the full and
natural air delivery of the unit.

Typical Factory

In the typical industrial building, where
ceilings are high, Model P Unit Heaters
may be used without diffusers.

Application Considerations

Figure A C-1 – The floor plan and elevation of a typical industr ial building showing ho w a
Trane Unit Heater System will heat var ious par ts. Where ceilings are high in the main
manufactur ing section, l arg e Projection Heat ers without dif fusers are used. Where ceilings
are exceptionally high, as in cr ane bays, Model P Units with Louver Cone Dif fusers pr ovide
up to 45% greater thr ow t o top the “ceiling heat r eservoir.” Model P Units with half closed
Louver Cones blanket doorwa ys. Model S Units with Louver Fins blank et windows.

In plants where the ceilings are
exceptionally high, such as in crane bays
as illustrated in Figure AC-1, Model P
Units with Louver Cone Diffusers can
increase the downward projection of
heat by as much as 45% over units
without diffusers.
Model P Units with the Louver Cone
Diffusers can also be used to blanket
doorways effectively, as shown in Figure
AC-1 by simply adjusting half of the
louvers vertically, and half closed.
Model S horizontal-type units are ideal
for mounting in plant areas where
ceilings are low. In fact, due to the

extremely small height of the Model S,
and because all piping connections are
made at the back of the unit, the Model S
provides a greater saving in headroom
than other horizontal unit heater makes.
As illustrated in Figure AC-1, the Model S
Unit Heaters may be mounted
conveniently from the ceiling, or from
building structural supports and beams.
With Louver Fin Diffusers, they are ideal
for blanketing windows, and Model S
“Bypass” Unit Heaters, provide further
flexibility of application where greater
throw and more effective distribution of
air in the living zone is required.

General Notes

The following general notes on piping
propeller unit heaters are presented
based on competent engineering and
installation practice:
1 . Suspend unit heaters securely with
provisions for easy removal.

2. Make certain units hang level vertically
and horizontally .

3. Provide for expansion in supply lines
(note swing joints in suggested piping
arrangements).

4. Provide unions adjacent to unit heaters
in both supply and return laterals. Also
provide shut-off valves in all supply
laterals.

5. Use 45' angle runoffs from all supply
and return mains.

6. Provide at least 7" (more if necessary)
clearance above tops of Model P
Projection Unit Heaters. Motors are
removable from below on all sizes.
It is desirable to form dirt poc kets with
pipe of the same size as the return
tapping of the unit heater. Pipe in the
branch-of f should be the same siz e as the
tapping in the trap. Beyond the trap, the
return lateral should be increased one
size to the return main.

Hot Water System – Using Cir culating
Pump

Overhead supply and return mains are
used with bottom connections to mains.
Manual vent (pet cock) is used at high
point on return main. Automatic air vent
may be substituted if desired. Refer to
Figure AC-2.

Figure AC-3

High Pressure Steam Syst em

Overhead supply main is used with
lower return main. Where steam
pressure fluctuates over a wide range, a
swing chec k valve should be placed in
the return lateral between strainer and
bucket trap to prevent reverse flow of
condensate of flash steam when
pressure drops suddenly. Top of buc ket
trap must be located below return outlet
of coil for complete drainage of
condensate. Refer to Figure A C-3.

Selection Pr ocedure

Trane Propeller Unit Heaters

Both Model S and Model P Propeller
Unit Heaters are ideally suited to such a
wide variety of installations that there
can be no hard and fast rules regulating
their selection.
In determining the type and size of the
units for any building, the following
points are generally considered:

BTU Requirements

While the choice of units depends upon
several important factors, the total Btu
requirement is usually determined first.
In calculating heat loss, methods as
recommended by the ASHRAE Guide
may be used, or any other procedure
which is known to be acceptable.

Type of Building

Once the total Btu requirement is known,
the type of building together with its
architecture and its purpose is
considered.
In the many cases where a combination
of space characteristics is found, a
combination of Model S and Model P
Unit Heaters may be used to create the
most satisfactory heating system.
The Model P Unit Heater has the natural
ability to tap the reservoir of heated air
which collects at the ceiling level and
return it to active service in the floor
zone.
The Model P can be used on either high
or low ceilings. From high mounting
positions the Model P will allow ample
clearance for moving objects and can
project heat down into occupied areas
regardless of obstacles which would
restrict the flow of air from horizontal
units.
From low mounting positions the Model
P, with proper diffusion, can be used
without disturbing nearby occupants
with direct blasts of high velocity heated
air, or requiring return lines so low as to
leave insufficient head room.
The superior horizontal action of the
Model S, on the other hand, is ideal for
creating a wiping effect of warm air
along exposed walls which neutraliz es
drafts at their source, beaming heat
down narrow aisles and production
lines, and blanketing large windows,
doors and other points of high heat loss.

Spacing of Units

It is the usual practice to divide the
building into areas with like exposures,
or in relation to heat load distribution
desired.
In general, Model S Unit Heaters may
be selected for buildings where direct
horizontal air currents are desired and
where there are no obstacles to
interrupt the flow of air from the
heaters.
Model P Unit Heaters are successfully
used where high or low mounting
heights are required and should
ordinarily be specified with diffusers,
depending upon the mounting height
and application.

Mounting Heights

maximum

The

height is determined by the outlet
temperature of the air, the outlet
velocity, the cfm for whic h the heater is
designed, and if a diffuser is used – the
setting of its blades.
The higher the outlet temperature of
the air, the more dif ficult it is to force it
down into the living zone.
The cfm also affects the mounting
height as a large volume of air will
travel farther than a small volume
under the same initial conditions of
temperature and velocity.
In the preliminary planning stages, it is
well to remember that the lowest
possible mounting height is desirable in
order to get the most heat down to the
floor line and to allow the greatest
possible diffusion adjustment to
provide tailor-made distribution for
each area.

effective mounting

In providing for the use of diffusers
please remember, adjustment of a
Louver Cone Diffuser to deflect the air
toward the horizontal immediately
lowers the mounting height limit.
Adjustment for lateral deflection with
the Louver Fin Diffuser shor tens the
distance of throw.

Diffusion

The use of T rane L ouver Cone or
Louver Fin Diffusers influences the
selection of units in two principal ways:
First: It is seldom necessary to install

oversized heaters to extend the
maximum effective mounting height of
the Model P or the distance of throw of
the Model S. Conversely, Trane Diffusers
enable extremely low mounting since the
adjustable blades direct heat where it is
wanted without creating uncomfortable
hot spots near the units.

Second: Af ter the original selection has
been made, units may be located with
confidence because adjustments in heat
distribution are possible to
accommodate future changes or
unforeseen draft conditions.

Air Changes

Better diffusion and more even
temperatures can be maintained in a
heated space when the rate of air
recirculation through the heaters is
relatively high. For buildings where large
numbers of people are engaged, it is
desirable to provide for a greater number
of air changes than for sparsely occupied
areas.
A greater number of small units are used
where wide diffusion and even
temperatures are necessary. A few
centrally located units of large capacity
would be used where there are few
occupants.

Comfort Conditions and Econom y

Air circulation, diffusion and spacing of
units are closely related to economy and
comfort in the selection of unit heaters.
The more units used to provide the
required number of Btu’s, the more
comfortable will be the conditions for
personnel. On the other hand, a few
large units can be selected to provide
plenty of heat at low first cost, but may
be slower in response and thorough
distribution of heat.
Here again, adjustable diffusion
equipment can go a long way toward
saving the buyer first cost expense while
still providing completely satisfactory
comfort conditions.

Pr ocedure

Formula

The following formula is used to arrive at
final air temperature volume when 70 F
(Standard Air Basis) is known or vice
versa:

Cfm at final temp. =
Cfm at 70 F x

Cfm at 70 F =
Cfm final air x

Determining Special Steam Capacities

Where capacity of the unit under
standard conditions is known – 2 lbs.
steam, 60 F entering air – and it is
desired to know the capacity of this
same unit under different steam and air
conditions, follow instructions given in
Example 1 below.

Where a set of conditions is given – Btu,
temperature rise, final temperature, cfm,
steam pressure available, etc. Refer to
Example 2.

Example 1

Given: Model 60S Horizontal Propeller
Unit Heater with a rated capacity of
60,500 Btu at 2 lbs. steam with 60 F
entering air.

Desired: Capacity of this unit using
15 lbs. steam and 40 F entering air.

Under 40 F and across from 15 lbs. in
SP-2, page 14, we find the factor 1.34.
60,500 x 1.34 = 81,070 Btu per hour .

Equivalent Direct Radiation

If working in EDR, rather than Btu,
multiply the EDR by the same factor in
the same way. Thus:

252 (From Table 3) x 1.34 =

81,070

338 sq. ft. or

Determining Amount of Condensate

To determine the amount of condensate,
divide the capacity in BTU by the latent
heat of steam:

81,070

945

945 = Latent Heat of Steam at 15 psi.

240

= 86 lbs per hour.

(See Table SP -9, page 18.)

Determining Final Temperature

Final temperature of air leaving T rane
Unit Heaters may be determined as
follows:

Inlet Air T emp. + Btu rating = FinalTemp

Cfm at 70F x 1 .085

Inlet Air Temp. 40F + 81,070 = FinalTemp

815(from table 3) x 1 .085

Example 2:

Problem: A Trane Model S Horizontal
Unit Heater is desired to deliver 280,000
Btu per hour in a garage where
ventilation is required. Entering air
temperature is 40 F. Steam at 30 lbs.
pressure is available. Temperature to be
maintained is 70 F.

Solution: Under 40 F and across from 30
lbs. in Table SP-2 page 1 4, find the factor
1 .51.

Equivalent capacity of required unit at
2 lbs. steam 60 F entering air is

Required Btu per hour = 280,00 =185,400

F 1 .51 Btu

From Table SP -3, page 15, select a
Number 186S Unit Heater with a
capacity of 185,200 Btu per hour with
standard coil, and at 2 lbs. steam and 60

F entering air.
Cfm x Temp. rise x 1.085 = Btu.
Specific heat of air (70 F) = .241
Specific weight of one cubic foot of air

(70 F) =.075.
Cfm x 60 = cfh.
Therefore, .241 x .075 x 60 = 1 .085

The capacity of this unit at 30 lbs. steam

and 40 F entering air is

1 .51 x 1 85,200 = 279,650 Btu per hour.

Surplus Capacity

While the ventilation load is being

handled, any air entering the space over

the desired room temperature should be

considered in the heating calculations.

This surplus capacity can be found by

multiplying the difference between the

final temperature leaving the heater and

the room temperature to be maintained

by 1 .085 and that by the cfm. That

amount of heat can be used to offset

heat losses.

Model S

Maximum mounting heights for Model
S Unit Heaters are given in Table SP-1.
When equipped with standard Louver
Fin Diffusers the distance of throw may
be increased as much as 25% by “toeing-
in” the ver tical blades.

Distance of throw
decreases in proportion to the amount of
deflection given the airstream to either
side of the heater.

Mounting the unit at or below maximum
mounting height will insure that heated
air reaches the living zone.

Model P

Maximum mounting heights for Model P
Unit Heaters are given in Table SP-1 0,
page 19. These distances are figured
from the floor line to the bottom plate of
the unit heater.
Where ceilings are unusually low, a
nearly horizontal flow of air can be
obtained by equipping these units with
Louver Cone Diffusers. The individually
adjustable blades of the Louver Cone
permit an infinite variety of adjustments
to meet any on-the-job problems. By
setting the blades vertically to straighten
the airstream, as much as 45% increase
in throw can be obtained.

Motor and Fan Speeds

Motor and fan speeds are selected to
provide efficient performance. The
solid-state speed control will provide an
infinite number of speeds between the
highest and the lowest cataloged fan
speeds. The speed control is not
calibrated in specific fan speeds. For use
on units with 115 volt/60 cycle/
1 phase, 1/8 hp and smaller standard
motors only.

Standard and Bypass Units

Standard models meet most
requirements and are most economical.
Bypass units meet conditions as
mentioned above, and are also used
where low final temperature is specified.

25 and 50 Cycle Unit Heat Capacities

Table SP-8 shows the Btu, cfm, and the
hp required on unit heaters when
operated on 25 or 50 cycle circuits.
The multipliers in T able SP-8 may be
applied to standard 60 cycle unit
capacities to determine the capacities of
the same unit when operating on
25 or 50 cycle current. These multipliers
may be used on units cataloged at
1050 to 1150 RPM.
For the smaller T rane Unit Heaters
cataloged at 1550 RPM, the capacity data
in the catalog may be applied to either
25 or 50 cycle service.

Hot W ater Selection Example

Selection Procedure

Select the proper size of unit heater for
whatever application desired, as
illustrated by the following examples.

Example 1:

Select a Model S horizontal unit heater to
deliver 95 MBH with 220°F entering
water temperature (EWT), 70°F entering
air temperature (EA T) and a 30°F water
temperature drop (WTD).

Step 1 .

Determine GPM:

Btu/hr = 95000 = 6.53

GPM =

Step 2.

Refer to Table SP -11 to select the
conversion factor at 220° EWT and 70°
EA T. Factor is 1.058.

Step 3.

Determine equivalent MBH at standard
conditions (200° EWT, 60° EAT).
Equiv. MBH =

Step 4.

Select unit size by entering the hot water
tables at the 200 °F EWT column. Select
the unit which will provide 89.8 MBH at

6.53 GPM. In this example, the selection
indicates a Model S
from Table PD-2, page 28.
To determine the actual capacity of this
Model S
(220° EWT and 70° EA T) proceed as
follows.

(485) WTD 485 x 30

MBH = 95 = 89.8

Factor 1 .058

126W2 unit heater,

126W2 at operating conditions

Step 1 .

Determine the MBH at 6.53 GPM by
interpolation in the 200° column. (In this

90.8 MBH.) Multiply this MBH by the

case
conversion factor 90.8 MBH x 1 .058 = 96
MBH.

Step 2.

The GPM remains constant = 6.53 GPM.

Step 3.

Calculate the water temperature drop
WTD =

Btu/hr = 96000 = 30.3
GPM x 485 (6.53) (485)

19UH-PRC001-EN

Selection
Pr ocedure

Step 4.

Determine the pressure drop at 6.53
GPM. Pressure drops are cataloged for
both standard wall (SWT) and heavy
wall. (HWT) tube coils. In this example, if
a SWT coil is selected the pressure drop,
by interpolation is

2.38 feet of water.

Example 2

Determine the capacity of a Model 336P
unit heater operating at 180° (EWT), 100°
(EA T) and 15° (WTD).

Step 1 .

Find conversion factor (in T able SP-11)
= 0.546

Step 4.

WTD = 27.5 x 0.546 = 15°

Step 5.

Btu/hr =123,000

GPM =

485xWTD (485)(15)

Step 6.

= 16.9

Pressure drop interpolated at 27.5° WTD

Step 5.

Calculate the final air temperature

= 27.5°

Step 3.

Multiply the MBH (interpolated) at

27.5° WTD, 200° EWT and 60° EAT by the
factor to obtain the MBH at desired

for a SWT coil is 1 .82 feet of water.

Step 7.

Calculate final temperature

conditions.

Note:
If a constant water temperature drop is desired, apply the conversion factor to the WTD and to the desired MBH and enter 200° EWT column at these conditions. Select the unit which will
provide the equivalent MBH at the adjusted WTD. The GPM can then be interpolated from the table at the adjusted WTD. To determine the actual capacity at operating conditions proceed as
outlined in example #2.
If a constant GPM is desired, enter the 200° EWT column at the given or calculated GPM. Select the unit which will provide the equivalent MBH at this GPM. To determine the actual capacity
at operating conditions in this case proceed as outlined in example #1.
