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 ring jet heater is handled,
installed or used. Emerson cannot and will
not guarantee that a ring jet is suitable for or

jet resulting in severe personal injury or property
damage.
2 INTRODUCTION
2.1 Features and specifications
Penberthy model RJ ring jet is designed for
heating liquids in line and tank by direct contact
with steam. The steam passes through a ring
shaped opening between the jet body and the
end of the nozzle and condenses into the liquid
within the discharge portion of the jet. The
model RJ ring jet is also designed to pump
granular solids or gases by using a fluid as
the operating medium, and to pump liquids
or slurries by using steam or a liquid as the
operating medium.
2.3 Application data
For heating in line (except the iron ring jet):
The Ring Jet is designed to operate at liquid
line pressures from 10 to 100 psig (69 to 689
kPaG) and steam pressures from 20 to 150 psig
(138 to 1034 kPaG) .
For heating in tank:
The ring jet is designed to operate at steam
pressures from 5 psig above submergence
(tank) pressure to 50 psig (30 to 340 kPaG).
Maximum liquid temperature for shallow tanks
is 150°F (66°C) when using 30 psig (210 kPaG)
steam.
For pumping:
The ring jet is designed to pump granular
solids or gases by using a fluid as the operating
medium at up to 50 psig (30 kPaG); and to
pump liquids or slurries by using steam or a
liquid as the operating medium at up to 50 psig
(30 kPaG).
Note: For specific application data within the
above ranges, the user should consult the
product proposal for the specific model and
size ring jet, 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 may
cause severe physical injury or property damage.
3.2 User's rating inspection
The user should confirm that:
1. The ring jet size (cast on side of body) and
model designation (stamped on nozzle hex
flats), 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 ring
jet are compatible with both the contained
fluid and the surrounding atmosphere in the
specific application.

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 ring jet.
Check the exploded view Figure 5 for the
location of the operating, suction, and discharge
connections to insure correct hook up.
4.1 Effect of related piping and precautions
1. All installations
a. The model RJ ring jet can be mounted and
will operate in any position. When heating,
it is more desirable to install the unit with
the side connection pointing up, to aid in
the removal of condensate in steam line at
startup.
b. The ring jet should be installed with piping
and fittings which provide the minimum
resistance to flow. Pipe line friction losses
must always be a consideration when
estimating ring jet performance.
c. It is recommended that provisions be
made for pressure gauge connections
near the operating, suction and discharge
connections of the ring jet. If operating
difficulties are encountered at any time, it
may be necessary to install pressure gauges
to identify the problem.
d. Steam must not have over 20°F (-7°C) of
superheat, or performance will differ from
that published in the relevant technical data
sheet or product proposal referred to above.
e. The motive fluid line must be clean and
provided with a strainer to prevent foreign
materials from clogging the ring jet.
f. The steam line should be insulated and as
short as possible to prevent condensation
and line friction losses.
g. Do not impose system piping loads on ring
jet. The unit is NOT designed to be a load
bearing component.
h. A check valve in the steam line located as
close to the ring jet as possible will help
prevent water from being driven into the
steam line at shutdown.

b. To prevent flow reversal into the inlet, install
a check valve in the liquid inlet line close to
the ring jet. Pressure drop created by the
check valve must be considered when sizing
the ring jet.

2. For heating in line
a. Some installations require the addition of
a bypass line (see Figure 1). Check with
the relevant technical data sheet or the
product proposal for the specific model
and size ring jet. When heating, the ring jet
is capable of discharging at up to 30 psig
(210 kPaG) above line pressure. The bypass line is recommended for installations
where the pumping action is undesirable.
Recommended by-pass line sizes are as
indicated in Table 2.

PENBERTHY MODEL RJ RING JET HEATER
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
3. For heating in tank
a. The ring jet should be positioned within
the tank so as to insure the free flow of
liquid to be heated into and out of the unit.
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
opening. Tank shape and size influence the
placement and number of ring jet heaters
required to assure even temperature
distribution. A spherical tank with a single
ring jet heater mounted as shown in
Figure2 makes the best use of the heating
and circulating characteristics of the ring
jet heater. With no corners to impede liquid
flow, the liquid circulates undisturbed while
being heated.
The angular intersection of surfaces in
cylindrical, square, or rectangular tanks
can interrupt liquid flow patterns and
cause liquid stagnation in these areas. A
single ring jet heater mounted as shown in
Figure3 will tend to minimize this effect.
However, multiple ring jet heaters can often
produce more efficient circulation when
using these tank shapes. To avoid significant
steam pressure drop, never use smaller
steam pipe than the heater connection size.
Long, narrow tanks whose ratio of length
to diameter is greater than 2:1 normally
require multiple ring jet heaters to maintain
even temperature distribution.
b. Ring jet heaters must be fully submerged
to prevent liquid from splashing and to
promote condensation of steam.
c. Clearance should be provided for removal of
the ring jet heater.
d. Steam piping must be secured to the tank
wall near the ring jet heater to keep strain
off piping when in operation.
e. The steam supply valve should be a quick
opening type installed as close to the ring jet
heater as practical.
f. Some installations require a specific
depth of submergence in order to achieve
maximum liquid temperature. Install the
ring jet within an outside circulating loop
if necessary to obtain submergence (see
Figure 4).

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
5 OPERATION
5.1 Pre-operational check
1. For in line installations
a. Ensure that all installation procedures have
been completed.
b. Ensure that any restrictions in the discharge
line have been removed.
c. Ensure that discharge line valves are fully
open.
2. For in tank installations
a. Ensure that all installation procedures have
been completed.
b. Ensure that the tank has sufficient liquid for
full submergence of the ring jet.
5.2 Operating
1. For in line installations
a. Turn the operating liquid valve fully open.
b. Slowly turn the operating steam valve
on until the desired discharge liquid
temperature is reached.
c. Regulate line discharge pressure if desired.
2. For in tank installations
a. Turn steam flow fully on and maintain
throughout the heating process.
b. After desired temperature is reached, steam
pressure should be turned off.
c. Do not throttle steam supply valve.
Throttling of steam flow to conditions
outside the recommended operating levels
will cause the ring jet 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 temperature for the specific
application. Heating beyond the maximum may
cause noise, vibration and release of live steam
resulting in splashing of liquid in the tank and
loosening of pipe connections causing property
damage or physical injury.
For specific application data on temperature
limitation, the user should consult the product
proposal for the specific model and size ring
jet, or should request supply of the applicable
technical data sheet.
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 ring jet 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 pressure resulting in
personal injury or property damage.
6.1 Preventative maintenance
The user must create maintenance schedules,
safety manuals and inspection details for each
specific installation of a ring jet.
On all installations, the following items should
be evaluated regularly by the user for purposes
of maintenance:
1. Ring jet for corrosion or debris buildup.
2. Piping and fittings for corrosion or debris
build up.
3. All connections for tightness and leaks.
4. Units for wear.
5. In tank units for full submergence.
6. Strainer for debris build up.
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.
