UF System backed by research and support
UF System is a critical component of the E-coating process. Any issues/errors will result in stoppage of the E-Coat line.
PolySep UF system is built upon rich experience and improvements over the years, supported by continuous research. As a result our UF system is most economical and stable.
E-Coat work/target carry out excess ED paint that did not form film. This excess paint is retrieved by rinsing with the UF permeate and returning the rinse solution back to the E-Coat system. This allows the E-Coat system to keep the paint loss at a minimum.
UF membrane is the most important component that interfaces with the ED paint. Various design considerations are made from both chemical and mechanical aspects of the product to keep the surface from getting clogged.
① UF Membrane
The UF module produces permeate as ED paint flows into the spacer portion of the module and filtered out at the membrane surface.
Supports the membrane under high pressure, and provides a channel for the permeate flow.
