Item Description

Heavy Duty Ion-Exchange Tower / Column


Ion Exchange Columns are essential for using the DudaLite DW-R10 Ion Exchange Resin in dry washing biodiesel. Simply load these columns with the resin approx. halfway, seal the top, and slowly push your unwashed biodiesel through it to filter out soaps, glycerin and other contaminates. Use of this product with DudaLite will bring your biodiesel to ASTM specifications and make the highest quality of fuel. No more waiting for water washing and no more disposal problems with the wash water. Our ion exchange resin can be thrown away with your regular garbage safetly.

All of our towers are professional welded, pressure tested and powder coated to last. Our towers are made of heavier, thicker material than others. The 6" diameter tower is 75 lbs empty, with 7 gauge flanges, 1/8 wall tubing, two 100 mesh stainless wire mesh screens and two support screens. They are also taller than others to allow for more expansion of the resin. With plenty of room for expansion there is less risk of tower damage to over filling. The 6" diameter towers are 54 inches top screen to bottom screen. 74 inches with tripod stand. Our 12" diameter towers are also taller. They are 76 inches top screen to bottom screen. All towers are also top to bottom or bottom to top flow. When you receive the tower you get to choose the direction of flow. In case of over pressurization all 100 mesh screens and support screens can be replaced very easily. No cutting or rewelding required. In case you should happen to get a ripped screen from over filling, Just unbolt the cover, unbolt the screen, replace screen, rebolt, and you're ready to go.

Made in USA.

Twin Towers: It is best practice to use two towers in series to allow full exhaustion of your resin prior to discarding it. The lead tower is allowed to remove most of the contaminates while the lag tower polishes off the biodiesel, making sure there are no contaminants left. As the lead tower begins to exhaust, the lag tower picks up on the slack and allows the lead tower to completely exhaust before a need to change the resin. Once completely exhausted, the lag tower becomes the lead tower, and the lead tower is refilled and then placed into the lag position. A third tower would be required in the case of a continuous operation where there should be little downtime during washing.

Twin Towers II: When a biodiesel user has high soap content (greater than 1000 ppm) it is recommended to do a methanol wash to the resin to prolong life of the resin. For some, this is a little time consuming. In the case of using two towers, a user can utilize the advantages of BD-zorb being in the first tower, and using the ion-exchange resin in the 2nd tower as a final polish. Since BD-zorb has a high soap absorption rate, it eliminates the need for a methanol wash on the resin.

Fluoroelastomer (Like Viton) Gaskets: Our towers are made with fluoroelastomer gaskets. These gaskets will never wear out from contact with the Biodiesel. Most other towers use regular rubber, which will require changing every so often.
