LL-142
Liquid Filters
The
Dollinger series LL-142 liquid filters are designed to remove
final traces of dirt, pipe scale and other solid contaminants
from process liquids.
Unlike conventional multiple-cartridge filters, the Dollinger
Element Design Concept maximizes the effective filtration
area for a given vessel size resulting in lower differential
pressure and extended service life. In addition to the standard
range of filters, Dollinger is able to offer customized
filter designs and capacities to suit the particular process
/ application demands of the customer.
Housing
and Design Construction
As standard, the Dollinger LL-142 filter housing is designed
and constructed in accordance with the ASME VIII, Division
I Pressure Vessel construction code. In addition, Dollinger
can also provide full design services to other pressure
vessel codes – Canadian and European.
Materials
of Construction
The standard materials of construction of the Dollinger
LL-142 filter are carbon steel or stainless steel. Where
appropriate, a cost-effective option incorporates a carbon
steel housing with stainless steel downstream of the filter
element. Special requirements for low temperature applications
can also be accommodated.
Filter
Element
The Dollinger LL-142 Filter incorporates the efficient radial
fin element design which provides the largest filtration
area for given element size. This increases dirt holding
capacity, minimizes pressure drop and results in an extended
service life. The filter media support structure utilizes
carbon steel or alternatively, stainless steel. The standard
element design ensures its integrity up to a differential
pressure of 50 psid. Special designs are available for applications
which demand higher differential capabilities.
Filter
Media
Dollinger offers an extensive range of synthetic and natural
fiber filter media suitable for use with most process liquids.
In addition, stainless steel mesh media can be incorporated
in the existing element design for more demanding applications.
In most instances the Dollinger filter element can be cleaned
and re-used many times. This feature is especially beneficial
in applications having high levels of contaminants.
Inter-Changeability
In the even of changing process conditions following installations,
it is possible to interchange elements to vary the degree
of filtration.
