Electrostatic Oil Purification Systems
Protect your hydraulic components and decrease equipment wear with an Electrostatic Oil Purification System for cleaning and maintaining the hydraulic oil in your plastics processing machinery.
CPT offers ASL Technologies electrostatic oil purification systems to extend the life of your plastics processing machinery and the life of your hydraulic fluids.
The ASL Technologies system will operate with any semi-conductive or non-conductive fluid, lubricant, or oil, within broad temperature and viscosity limits. The system’s ability to remove the pre-cursors of oxidation by-products will prevent and, over time, remove existing tar and varnish deposits.
Thousands of these systems are in use worldwide. The Electrostatic Cell’s unique back flush capabilities extend its life span to 8,700 hours (one year of 24/7 operation). The system is inexpensive to purchase and inexpensive to operate.
How the Electrostatic Oil Purification System Works…
ALL other fluid filtration systems work by utilizing "size exclusion" MEDIA in the form of pleated or woven paper or other "screening" material, which quickly clogs and must be replaced often.
ASL's Patented Electrostatic Fluid Purification Systems USE NO SIZE EXCLUSION MEDIA. Working on the principles of Electrostatics and Electromagnetics, particulate is held within the Electrostatic Cell by these forces until power is removed from the Electrostatic Cell. Entrapped Particulate can then be back-flushed out with shop air by the operator.
- Fluid is drawn from the bottom of your reservoir by a self-contained pump and motor located within the ASL System.
- The fluid is first passed through a 5 micron (nominal) water absorber/pre-filter, where larger contaminants as well as free and emulsified water are removed.
- From the water absorber, fluid is then passed into the Electrostatic Cell. Fluid flows from bottom to top through the Cell. Exiting the Cell, fluid is returned to the top of your reservoir. The "kidney-loop" system is designed to operate 24/7, independent of your machine operations, providing a continuous stream of purified fluid to your machine.
- As fluid (and particulate) enters the Cell, it first passes through two perforated plates which are tied to the negative side of the High Voltage DC power supply. Particulate in the fluid receives a negative charge as it passes through these plates. Coulombs force (likes repel) rejects these charged particles away from the negative plate, sending them upward toward the next plate in line which is tied to the positive side of the High Voltage DC power supply.
- Just before the positive plate, the rising particulate encounters the toroidal flux field emanating around two ceramic magnets, which are buried in the foam insulating traps. Particulate entering this field is resisted at some places and accelerated at others, becoming "strawed" into the porous foam.
- Other particulate, being drawn toward the positive plate, encounters a revolving corona, arcing around the intense localized electrical field of the positive plate.
