    The Parker SMR Series Submicronic Removal Fluid Purification System is the smart purification solution for fluid flow around 10 GPM (38 LPM). The SMR contains Parker patented Balanced Charge Agglomeration (BCA™) technology, which maintains hydraulic and lubricating fluids in optimum condition while preventing/removing the build-up of sludge and varnish.

    Balanced Charge Agglomeration (BCA™) technology does not remove water, however with the removal of thousands of submicron particles; the majority of sites where water can readily attach are mitigated. Water is more easily separated and removed, improving demulsibility, or the ability to release water.   
    Demulsibility is an important factor to consider when hydraulic equipment operates in an atmosphere that is wet or humid. Food-processing operations, such as cooking oil, for example, provide significant exposure to water-based process fluids.

    Because oil is hygroscopic, or able to absorb water, it is quite easy for water to saturate the oil. Water enters through any number of ways, and must be removed in order to protect a system’s operation. When demulsibility is diminished, the oil will become contaminated by the water, causing quick wear to the system’s components.

    Maintaining a hydraulic system’s oil cleanliness level will increase the life of the critical wear components, and reduce system downtime. Portable purification units are ideal for systems in applications demanding on-site decontamination. With several models to choose from, the Parker SMR Series is an ideal solution for many hydraulic system’s needs.

    This system is available in a PLC or simplified control version. Please contact a Parker Representative for assistance.

    Balanced Charge Agglomeration (BCA™) - How the Technology Works:
    Contaminated fluid is passed over a series of high-voltage electrodes, inducing a charge on the submicron particles of (+) and (-), then the particles continue down separate paths. (Note that particulate contamination as small as 0.1 microns are able to amass this charge). Oil, a non-conducting fluid, remains neutral. The two oppositely charged particle fluid streams are then re-combined. The oppositely charged particles are then mixed and are attracted to each other, forming larger particle clusters, growing in size as they agglomerate, or join together. Submicron particles grow into multiple micron-sized particle clusters. Once larger in size, the particle clusters are more efficiently filtered. Finally, the particle clusters are then sent through the system’s high efficiency filter to be removed.
