Structural, Wound Polyglass, Ion Exchange Resin Vessel / Tower

For general use with all Ion Exchange Resins, these towers are used for the dry-washing of Bio Diesel.

NOTE: For optimum performance, the tower should not be filled with more than 50% of its capacity with resin to allow for expansion of the resin.

IMPORTANT - IF THE VESSEL IS FILLED WITH RESIN TO GREATER THAN 50% OF ITS TOTAL CAPACITY, THE RESIN, AS IT REACHES EXHAUSTION WILL DESTROY THE DISTRIBUTION SYSTEM AND BLOW OUT OF THE TOP, YOU WILL THEN NEED A REPLACEMENT DISTRIBUTION SYSTEM. WE THEREFORE RECOMMEND WHEN FILLING YOUR OWN TOWER THAT YOU COMPLY WITH THE MAXIMUM RECOMMENDED VOLUME.

Construction
Constructed from wound Polyglass, wrapped around a strong Polyethylene Inner Shell, and fitted with a Polypropylene & PVC Distribution Tube.

Sizes
Available in various sizes, with the most popular models being OC-206/20L which has dimensions 18 x 90cm and a volume of 20 liters, and will hold 10 liters of Resin, purifying Bio Diesel at a rate of 20 liters per hour. The next most popular model is the OC-206/44L whose size is 23 x 122cm, having a volume of 44 liters, and which holds 22 liters of Resin, purifying Bio Diesel at a rate of 44 liters per hour. For any other sizes please contact us for a quote.

Pumped Supply
There are two methods for pumping the biodiesel through the resin tower. The first is using gravity, and the second is using a pump. In most cases, where the pre-washed biodiesel can be positioned in a tank higher than the final storage tank, gravitation is used. There are few pumps which will normally pump as slow as is required to supply the smaller vessels. We can supply such pumps if requested.

Emptying & Discharging
Emptying these towers can be a messy business, this is because the resin eventually expands to fill the vessel and it can be difficult to 'dig' it out around the central shaft. In this case it may be necessary to unscrew the cap, and wash the resin out with bio diesel via the distribution system, filtering the resin out of the bio diesel as it comes out of the tower, the resin can then be disposed of. To replace the resin, the vessel should be filled to 50% of its capacity and led down for the distribution tube to be screwed in without having to force it down into the resin, potentially damaging the tube.
