Operating Temperature - Pall SUPRApak Serie Notice D'installation Et D'utilisation

Unless stated otherwise, the term "SUPRApak" refers to both SUPRApak SW, ZD, SR and SH as well as SUPRApak
Plus PW, PZ, PH and PR module types.
1 Introduction
The following procedures must be followed for the installation and operation of SUPRApak filter units.
These instructions, as well as the product data sheets and SUPRApak filter housing operating instructions,
should be read thoroughly as they contain valuable information gained by extensive experience. It is very
important that all instructions are carefully followed and, where appropriate, incorporated into the operator's
standard operating procedures.
If some of the procedures do not suit your needs, please consult Pall or your local distributor before finalizing
your system.
Use of this product in a manner other than in accordance with Pall's current recommendations may
lead to injury or loss. Pall cannot accept liability for such injury or loss.
2 Specifications
This product is intended for use in the forward direction only. It is not intended for use in the reverse direction.
Appropriate installation guidelines should be followed in order to prevent back pressure shocks to the
filter modules.
Operation outside the specifications and with fluids incompatible with the materials of construction
may cause personal injury and result in damage to the equipment. Incompatible fluids are those
which chemically attack, soften, stress or adversely affect the materials of construction. For chemical
compatibility, please contact Pall.

Laboratory tests at high temperature up to 8 hours exposure. Actual field experience shows substantially longer resistance to
continuous high filtration temperatures. For continuous filtration temperatures over 40 ºC (104 ºF) a stainless steel support
core must be used. See Section 4.1 for further details.
2.2 Differential pressure
The differential pressure of SUPRApak modules is application-specific. It is influenced by fluid type,
temperature, viscosity at filtration temperature, flux (flow rate/module), nature of contaminants and
the suspended solids load.
2.2.1 Maximum differential pressure
The maximum differential pressure during filtration is the differential pressure value at which
turbidity breakthrough occurs and/or the filtrate quality is no longer acceptable.
This performance is application-specific, and should be monitored by downstream turbidity or
other filtrate quality measurements.
For many typical applications in aqueous fluids (e.g. distilled spirits, beer, wine, tea, etc.) sized
at initial clean differential pressures well below 1 bar, the recommended maximum differential
pressures are shown in Table 2.

1 Recommended maximum differential pressure is related to SUPRApak modules only. Differential pressure resulting from the
housing (containing no modules) and surrounding piping is not included and can be added to the recommended maximum
differential pressure of the modules.
2 Indicated differential pressure values are based on modules used with a stainless steel support core. See Section 4.1(a).
On non-aqueous fluid installations, with higher viscosity and potentially higher initial clean dif-
ferential pressures, the maximum differential pressures at which turbidity breakthrough occurs
must be validated by pilot testing.
Please contact Pall for additional guidelines for expected performance.
2.2.2 Collapse Pressure
The collapse pressure of SUPRApak modules is higher than the recommended maximum dif-
ferential pressure at which turbidity breakthrough may occur.
The presence of a stainless steel support core adds stability to the modules in applications at
high temperature. The indicated collapse pressures in the following table are based on labora-
tory testing of cores only. Actual collapse pressures may be equal to these core collapse values or
higher, depending on the application specifics, as the surrounding sheet materials deflect the
stresses on the cores.
Section 4.1(a) describes the use of stainless steel support cores in applications greater than
40 °C (140 °F).

Any pressure shocks in forward or reverse direction must be avoided, both for fluids as well as
during gas displacement of fluids. Please refer to SUPRApak housing installation and operating
instructions for further details.
