PENBERTHY MODEL RJ RING JET 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 ring jet heater is handled,
installed or used. Emerson cannot and will
not guarantee that a ring jet is suitable for or
compatible with the user's specific application.
WARNING
Always wear safety glasses when in the area
of a ring jet installation. Failure to follow any
instruction may cause a malfunction of the ring
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.
IMPORTANT
If the size, model or performance data of the ring
jet as received does not conform with any of the
criteria above, do not proceed with installation.
Contact an authorized Penberthy distributor for
assistance.
Unless otherwise specified on a relevant
technical data sheet, the iron ring jet is NOT

provided, the specifically stated design limits on
a product proposal.

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.
