Since 1974, Encyclon has been manufacturing cyclonic filtration systems. Our knowledge and applications experience has made us a leader in the industry.
Encyclon Cyclonic Filtration Systems filter, circulate and store coolants for metalworking and other water-based or synthetic liquid operations. These systems employ no filter media or diatomaceous earth. They operate on the simplest, most efficient means of separating foreign particles from liquids: centrifugal force generated in a cyclonic chamber. And because of its double cleansing action, the Encyclon cyclonic chamber removes 98% of all particles, without impairing the original chemical properties of the coolant.
Our Type Number 28 cyclone offers 3 micron filtration and a 5 gallon per minute flow rate. Type Number 65 cyclone offers 5 micron filtration and a 20 gallon per minute flow rate. The number of cyclones fitted on a system will vary, depending on the flow rate you require.
To grasp the efficiency of cyclonic filtration, consider a grain of sand. The size of this grain is approximately 40 microns. Cyclonic filtration is capable or removing particles 8 to 13 times smaller than this grain of sand.
And remember: no filter media is needed, only cyclonic force.
Here’s how the process works:
- Dirty liquid enters the cyclone at the inlet orifice of the cyclonic chamber.
- The shape and tangential location of the orifice develop a downward, spiraling flow of the liquid. This is called the primary whirl, which follows the chamber walls downward, developing centrifugal force of up to 7500 times that of gravity.
- This same force spins out the solid particles to 5 microns, or .00019” diameter from the liquid. The solid particles (often referred to as swarf) strike the wall and slide down to the discharge orifice.
- A throttling effect in the lower cyclonic chamber reverses the descent of the liquid but not the rotation. This forms the secondary whirl, a rising, spiraling flow of cleaned liquid that passes up through the primary whirl to the whirl searcher.
- The diameter of the whirl searcher is smaller than the secondary whirl, and the whirl searcher accepts only the center of the upward, secondary whirl flow.
- The outside portion of the secondary whirl (containing impurities missed by the primary whirl) is diverted back to the primary whirl for further cleansing.
- This double cleansing action is key to the efficiency of the Encyclon Cyclonic Filtration Systems.
- Liquid that passes through the whirl searcher is then piped out to the clean coolant storage tank or to the machine tool.
Your Encyclon System can be ordered from the many standard systems that are available. If you have a special need, Encyclon Cyclonic Filtration Systems are the answer. Since we manufacture all of our systems, we can modify or custom-build a unit to meet your unique requirements.
All units can be equipped with “Little Tramp” oil removal devices, refrigeration systems, magnetic separators, auxiliary clean coolant pumps, standby pumps, electrical controls, additional swarf containers and “New Life” UV generators.
