PENBERTHY MODELS XL-32 AND NWH STEAM JET HEATERS
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 steam jet heater is handled,
installed or used. Emerson cannot and will
not guarantee that a steam jet is suitable or
compatible for the user's specific application.
WARNING
Safety glasses should always be worn when
installing a steam jet heater. Failure to follow any
instruction could possibly result in a malfunction
of the heater with resulting physical injury or
property damage.
2 INTRODUCTION
2.1 Features and specifications
Penberthy Models XL-32 and NWH steam jet
heaters are designed for heating liquids in a
tank by direct contact with steam. Steam is
injected into the system under pressure causing
circulation and suction of liquid to promote even
temperature distribution.
2.2 Design ratings at maximum and minimum
operating temperatures (see Table 1)
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.
Note: For specific application data within the
above ranges, the user should consult the
product proposal for the specific model and
size NWH and XL-32 heater, 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 INSPECTION AND PERFORMANCE
CONFIRMATION
3.1 Receiving inspection
Upon receipt of the steam jet heater, 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 steam jet heater 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
steam jet heater are compatible with both
the contained fluid and the surrounding
atmosphere in the specific application.
2.3 Application data
NWH - Maximum liquid temperature for
noiseless operation is 160°F (71°C). Minimum
steam operating pressure is 10psig (70kPaG).
XL-32 - Maximum liquid temperature for
noiseless operation is 160°F (71°C). Minimum
steam pressure for noiseless operation is
60psig (415kPaG) when not using the air bleed
(operation at steam pressures below 60psig
(415kPaG) requires adjustment of an air bleed
valve to gain the quietest operation). Minimum
steam operating pressure when using air bleed
is 3psig (20kPaG).

Bronze and stainless steel 140 psig [965 kPaG] at -20°F [-29°C] to 360°F [182°C]
IMPORTANT
If the size, model or performance data of the
steam jet heater as received does not conform
with any of the criteria above, do not proceed with
installation. Contact an authorized Penberthy
distributor for assistance.
