PENBERTHY STEAM RING HEATER
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS

6.2 Troubleshooting

TABLE 2
Problem
Surges in liquid flow
Both steam and hot liquid are
produced by heater
Gravel like sound coming from
heater
Heater produces high frequency
noise
Note: Refer to noise band information stated in the relevant technical data sheet.

7 REMOVAL - DISASSEMBLY - REASSEMBLY

WARNING
Do not proceed with removal of the SRH from
connecting piping unless the SRH 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 do so could result
in serious personal injury or property damage.
7.1 Disassembly
a. If nut (4) is difficult to remove, heat the SRH
to 350°F (177°C).
b. Remove O-rings (39, 39A) and nozzle (61).
c. All removed O-rings should be
destroyed and disposed of and under no
circumstances should be re-used and
installed in a SRH.
d. Inspect nozzle for wear or damage and
replace if necessary.
7.2 Reassembly
a. Prior to reassembly, O-rings must be
lubricated with General Electric Versilube
0300 silicone grease or equivalent.
b. Assemble nozzle and O-ring (39) into body
(11) of SRH.
c. Apply Loctite type CVV or equivalent to
®
threads of nut and assemble O-ring (39A)
and nut inside body of SRH.
d. Replace SRH into piping system using PTFE
tape or equivalent on all male pipe threads
as shown in Figure 2.
e. Refer to Section 5 when returning SRH to
service.
Cause
Pumping action
Not enough liquid flow, or too
much steam flow
Steam pressure is only ½ to
2 psig (0 to 10 kPaG) above
liquid pressure
Heater is operating in the noise
range

8 DISPOSAL AT END OF USEFUL LIFE

Penberthy steam ring heaters 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 SRH 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
applicable technical data sheets for materials of
construction.

9 TELEPHONE ASSISTANCE

If you are having difficulty with your SRH,
contact your local Penberthy distributor.
So that we may assist you more effectively,
please have as much of the following
information available as possible when you call:
- Model #
- Name of the company from whom you
purchased the SRH
- Invoice # and date
- Process conditions (pressure, flow rates, tank
shape, etc)
- A brief description of the problem
- Trouble shooting procedures that failed
If attempts to solve your problem fail, you
may request to return your steam ring heater
to the factory for intensive testing. You must
obtain a Return Authorization (R.A.) number
from Emerson before returning anything.
Failure to do so will result in the unit being
returned to you without being tested, freight
collect. To obtain an R.A. number, the following
information (in addition to that above) is
needed:
- Reason for return
- Person to contact at your company
- 'Ship-to' address
Solution
Increase pressure discharge
Reduce steam pressure or increase
liquid flow
Cycle steam on and off instead of
throttling, or use smaller heater so that
steam pressure will have to be increased
Either raise or lower liquid pressure
outside the noise range
Tape
1-2
threads
FIGURE 2
There is a minimum charge for evaluation
of non-warranty units. You will be contacted
before any repairs are initiated should the cost
exceed the minimum charge. If you return a
unit under warranty, but it is not defective, the
minimum charge will apply.
