Installation and Operating Guidelines
UltiFuzor™ Degas Module
3.0 Installation and Start-up General
Guidelines
3.1 UltiFuzor degas modules can be installed
in any orientation; vertical orientation is preferred
for best performance. If placed horizontally,
position the vacuum ports to face downward to
facilitate draining of any potential condensable
vapor.
3.2 Connect ink inlet / outlet and vacuum ports. (See
figure 2.) Verify that connection surfaces are clean
and not damaged. Make sure not to over tighten
the luer lock fittings.
3.3 The module can be operated with only one
vacuum port, by capping off the other port.
Depending on the type of ink and / or extent of
degassing required, using both ports may provide
more efficient gas removal.
3.4 In order to avoid drawing any condensable vapor
or liquid ink (in the case of damage to the UltiFuzor
module) into the vacuum source, a trap may be
placed between the vacuum port of the module
and the vacuum pump (figure 3). This device
should utilize standard trap construction with a
vacuum tight vessel that can collect liquids and
be drained periodically, if required. If safety is a
concern, this trap may be maintained at a low
temperature to condense any solvent that might
evaporate from the ink, due to the applied
vacuum.

instructions. Gradually apply vacuum to the

3.6 Make sure that the absolute vacuum pressure
is not lower than the vapor pressure of the
most volatile component in the ink. The lower
the absolute pressure on the vacuum side of the
module (that is, the deeper the vacuum), the
greater is the likelihood that the ink carrier liquid
may evaporate into the vacuum. This can happen
if the absolute pressure on the vacuum side
approaches the vapor pressure of the carrier
liquid (or other components present) at the
operating temperature. It is generally
recommended that if the vapor pressures of ink
components are unknown, that the operator
starts by employing a somewhat higher absolute
pressure, for example, 13.4 kPa absolute (100
torr). Vacuum can then be adjusted as needed.
3.7 Slowly introduce the ink into the module.
4.0 Module Replacement
4.1 Stop flow, gradually release vacuum, isolate the
UltiFuzor degas module and depressurize through
system drain valve.
4.2 WARNING! Before attempting to remove the
module from the system, ensure that it is fully
isolated and depressurized. Failure to do so
could result in a rapid discharge of liquid,
which could cause personal injury and
damage to equipment.
4.3 Disconnect the module from the system. Note, a
small amount of ink may be released from the
module when it is disconnected.
4.4 Handle and discard the module in accordance
with local health and safety procedures
associated with the process fluid.
4.5 Install new UltiFuzor degas module per section 3.
4.6 UltiFuzor degas modules are consumable
products and intended for exposure to one ink.
The use of multiple inks is not recommended as
ink compatibility interactions may diminish
performance or damage modules. Flushing or
cleaning is not recommended.
