PENBERTHY MODEL CTE MIXER / HEATER

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

1 ABOUT THE MANUAL

This manual has been prepared as an aid and
guide for personnel involved in installation or
maintenance. All instructions must be read and
understood thoroughly before attempting any
installation, operation or maintenance.

IMPORTANT

Emerson does not have any control over the
manner in which its CTE is handled, installed or
used. Emerson cannot and will not guarantee that
a CTE is suitable for or compatible with the user's
specific application.

WARNING

Safety glasses and protective clothing should be
worn installing a CTE mixer/heater. Failure to
follow any instruction may cause a malfunction
of the unit in which high pressure liquid or steam
may discharge from the unit inadvertently,
resulting in severe personal injury and property
damage.

2 INTRODUCTION

2.1 Features and specifications

Penberthy CTEs (circulating tank eductors) are
designed for in-tank mixing of liquids as the
motive fluid and for in-tank heating of liquids
using steam as the heating and motive fluid.
Mixing is accomplished first within the CTE as
the motive liquid entrains the tank contents
into the suction openings and mixes with the
unit thoroughly before being discharged. The
discharge flow, or plume, provides further
mixing and agitation within the tank. The motive
liquid can be drawn from the tank or it can be a
second liquid drawn from another source.
Heating is accomplished by direct condensation
of steam in the liquid. The motive steam also
includes the liquid to flow into the suction
openings and discharge from the CTE. The
discharge flow or plume provides further mixing
and circulation to promote even temperature
distribution.

2.2 Design ratings at maximum and minimum
operating temperatures

To determine the maximum allowable working
pressure for a specific temperature within
the design limits stated in Table 1, the user
should refer to relevant data sheets or, when
provided, the specifically stated design limits on
a product proposal.

2.3 Application data

CTE sizes above 3 inches are metal fabrications
to be used only for mixing, not for heating.
Unless otherwise specified on a product
proposal, metal fabrications are not designed
for steam heating in tank.

1. Mixing

Minimum inlet pressure - 10 psig (70 kPaG)
Maximum inlet pressure - 160 psig (1100 kPaG)
Most efficient operation takes place when
inlet pressure is within the range of 20 to
70psig (140 to 480 kPaG). Three gallons of
tank contents can be mixed for every gallon
of operating fluid. For inlet pressures outside
this range, 2.6 gallons of tank contents can be
mixed for every gallon of operating fluid.

2. Heating (see Table 2)

Operation at steam pressures below
those listed for each maximum tank liquid
temperature or heating beyond 160°F (71°C)
may cause objectionable noise, water hammer,
and vibration.

Note: For specific application data within the
ranges stated, the user should consult the
product proposal for the specific model and
size CTE, or should request the supply of the
applicable technical data sheet.

WARNING

Under no circumstances should these design
ratings or application data be exceeded.
Exceeding design ratings or application data
can cause the CTE to fail structurally at higher
pressures and temperatures causing severe
personal injury and property damage.

3 INSPECTION AND PERFORMANCE
CONFIRMATION

3.1 Receiving inspection

Upon receipt of the CTE, check all components
carefully for damage incurred in shipping. If
damage is evident or suspected, do not attempt
installation. Notify the carrier immediately and
request a damage inspection.

3.2 User's rating inspection

The user should confirm that:

1. The CTE size and model designation (cast on
side of body) conforms to the description on
the user's purchase order.

2. The operating conditions described in
the purchase order agree with the actual
operating conditions at the installation site.

3. The actual operating conditions at the
installation site are within the application
data shown on the relevant technical data
sheet or product proposal referred to above.

4. The materials of construction of the CTE are
compatible with both the contained fluid and
the surrounding atmosphere in the specific
application.

IMPORTANT

If the size, model or performance data of the
CTE as received does not conform with any of the
criteria above, do not proceed with installation.
Contact an authorized Penberthy distributor for
assistance.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

4 INSTALLATION

Installation should only be undertaken by
qualified, experienced personnel who are
familiar with this equipment and have read and
understand all the instructions in this manual.
The user should refer to the relevant technical
data sheet or product proposal to obtain
dimensional information for the specific size
and model of CTE.
Check the cut-away view (Figure 1) for the
location of the threaded inlet.

4.1 Mounting

A CTE can be mounted in any position. The
supply line and manifold piping to multiple
CTEs must be sized to supply uniform pressure
to each CTE.
It is important that the CTE be positioned
within the tank so as to insure the free flow of
liquid to be mixed or heated into and out of the
unit(s). The greatest agitation occurs within the
discharge plume; therefore, the discharge end
should be aimed towards the most remote part
of the tank. On the other hand, the intake end
of the unit must be far enough from the tank
corner or wall to allow the free flow of liquid
into the suction openings.
Tank shape and size influence the placement
and number of CTEs required to maintain even
agitation or temperature distribution. With a
spherical tank, a single CTE mounted as shown
in Figure 2 makes the best use of the mixing
and heating characteristics of the CTE. With
no corners to impede liquid flow, the liquid
circulates evenly and undisturbed.
In a cylindrical, square or rectangular tank, the
angular intersection of surfaces can interrupt
liquid flow patterns and cause liquid stagnation
in these areas. A single CTE mounted as shown
in Figure 3 will minimize this. Whenever the
ratio of length to diameter of the tank is greater
than 2:1 (such as tank trucks or railroad cars),
it is recommended that multiple CTEs be used.

4.2 Effect of related piping and precautions

1. For mixing

a. Operating liquid supply line pressure loss

must be taken into account when applying
CTEs.

b. Supply line must be clean and should be

provided with a strainer to prevent foreign
materials from clogging the mixer.

c. CTEs must be fully submerged to prevent

liquid from splashing and drawing
atmospheric air, and to promote maximum
mixing.

d. Clearance should be provided for removal of

the CTE.

e. Provisions should be made for a pressure

gauge connection at or near the CTE
inlet. It may become necessary to install a
pressure gauge if operating difficulties are
encountered.

FIGURE 1

Inlet

FIGURE 2

Spherical

FIGURE 3

f. Inlet piping must be secured to the tank wall

near the CTE to keep strain off piping when
in operation.

g. Supply line and manifold piping must be

sized to supply adequate pressure equally to
each CTE when multiple CTEs are used.

2. For heating

a. Steam must not have more than 20°F (-7°C)

of superheat or performance will differ from
that published in the relevant technical
data sheet or product proposal referred to
previously.

b. Steam line pressure loss must be taken into

account when applying CTEs.

c. The steam line must be clean and should be

provided with a strainer to prevent foreign
materials from clogging heater.

d. The steam line must be insulated and as

short as possible to prevent condensation
and friction losses.

e. CTEs must be fully submerged to prevent

liquid from splashing and to promote
condensation.

f. Clearance should be provided for removal of

the CTE.

g. Provisions should be made for a pressure

gauge connection at or near the CTE
inlet. It may become necessary to install a
pressure gauge if operating difficulties are
encountered.

h. Steam piping must be secured to the tank

wall near the CTE to keep strain off piping
when in operation.

i. The steam supply valve must be a quick

opening type installed as close to the CTE as
practical.

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

5 OPERATION

5.1 Pre-operational check

1. Ensure that all installation procedures have
been completed.

2. Fill the tank with sufficient liquid for full
submergence of the CTE.

5.2 Operating

1. For mixing

a. Turn operating fluid flow on (depending

upon the application, this may be liquid
drawn from the tank, or it can be a second
liquid drawn from another source).

2. For heating

a. Turn the steam flow fully on and maintain

throughout the heating process.

b. After the desired temperature is reached,

the steam pressure should be turned off.

3. Do not throttle the steam supply valve.
Throttling of steam flow to conditions
outside the recommended operating levels
will cause the CTE to hammer with resulting
noise and vibration.

IMPORTANT

Excessive vibration can become hazardous due to
loosening of pipe joints and release of steam.

Temperature of liquid can be controlled
thermostatically only if the steam supply is
controlled with a snap acting on-off valve.

WARNING

Do not attempt to heat liquid beyond the
maximum stated temperature of 160°F (71°C).
Where the user has an open tank installation,
heating beyond the maximum does not allow the
steam time enough to condense fully by the time
it reaches the surface of the liquid, thus splashing
can result causing severe personal injury or
property damage.

6 MAINTENANCE

WARNING

Maintenance should only be undertaken by
qualified, experienced personnel who are
familiar with this equipment and have read and
understood thoroughly all the instructions in this
manual.
DO NOT proceed with any maintenance unless the
CTE has been relieved of all pressure or vacuum,
has been allowed to reach ambient temperature
and has been drained or purged of all fluids.
Failure to follow these instructions may cause
a sudden release of liquid or steam resulting in
severe personal injury or property damage.

The user must determine an appropriate
maintenance schedule necessary for his or her
own specific application upon evaluation of their
operating experience. Realistic maintenance
schedules can only be determined with full
knowledge of the services and application
situation involved.

6.2 Troubleshooting (see Table 3)

Example: A CTE is employed in raising the

water temperature in a given tank from
ambient to 160°F (71°C) and it is sized to
accomplish the job using 50 psig (340 kPaG)
steam over a period of 30 minutes. Once
the tank temperature reaches 160°F (71°C),
obviously it will take much less quantity of
steam to maintain the tank at 160°F (71°C)
than it did to get there. If the steam flow was
throttled to maintain 160°F (71°C) in the tank,
the steam pressure would drop necessarily
below 50psig (340 kPaG) at the CTE and then
noise and vibration can be expected. 50 psig

6.1 Preventative maintenance

The user must create maintenance schedules,
safety manuals and inspection details for each
specific installation of a CTE mixer/heater.
On all installations, the following items should
be evaluated regularly by the user for purposes
of maintenance:

1. CTE(s) for corrosion or debris buildup.

2. Piping and fittings for corrosion or debris
build up.

3. All connections for tightness.

4. Units for wear.

5. Units for full submergence.

(340 kPaG) is the recommended minimum
steam pressure for quiet operation when the
tank temperature is 160°F (71°C).

7 DISASSEMBLY - REASSEMBLY

WARNING

Do not proceed with removal of the CTE from
connecting piping unless the CTE has been
relieved of all pressure or vacuum, has been
allowed to reach ambient temperature and has
been drained or purged of all fluids. Failure to
follow these instructions may cause a sudden
release of liquid or steam resulting in severe
personal injury or property damage.

8 DISPOSAL AT END OF USEFUL LIFE

Penberthy CTEs are used in a variety of fluid
applications. By following the appropriate
federal and industry regulations, the user
must determine the extent of preparation
and treatment the CTE must incur before its
disposal. A Material Safety Data Sheet (MSDS)
may be required before disposal services accept
certain components.
Metal, glass and polymers should be recycled
whenever possible. Refer to order and relevant
data sheet for materials of construction.

9 TELEPHONE ASSISTANCE
