The unit is also valved so that series flow is possible for non-dissolved water oil handling applications, such as removal of dirt and free water. Use FO filter cartridges in the first housing to remove dirt particles. An Aquacon® cartridge in the second stage removes free water. The flowmetertotalizer feature allows the user to calculate the approximate lifetime of the Superdri® cartridges without an on-line moisture monitor. For dissolved water removal from transformer oil, the MXP5E is an economical alternative to more costly heat and vacuum systems.
