Spectrum, Wound Polyglass, Ion Exchange Resin, HIGH YIELD Pressure Vessel / Tower

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

These high-yield vessels have a different distribution system to normal vessels, and this enables the liquid to travel up through the whole body of resin, rather than up a central core, this means the service interval is extended due to more of the resin being utilized

For optimum performance, resin manufacturers recommend a minimum resin bed depth of 3 times the vessel diameter, the tower should also be filled with only 50% of its capacity with resin to allow for expansion

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 3 sizes, with the most popular models being 0835 08" x 35" has a volume of 23.6 litres, and will hold 11.8 litres of Resin, purifying Bio Diesel at a rate of 11.8 litres per hour.

There are few pumps which will normally pump as slow as is required to supply the smaller vessels. For the least costly option we recommend our Clarke BIP1000 Pump, the flow from this pump can be restricted as low as is desired by using a ball valve on its outlet and timing the through flow (using a measuring jug & stop watch) until you get the correct flow rate. For the biggest units a continous duty gear pump such as the Viscomat Gear Series would be most appropriate due to the increased resistance of the Resin. There is no way of determining the resistance of the resin in a given vessel, so if you have a large tower and the Clarke BIP1000 Pump begins to struggle, then you may need to upgrade to the Viscomat Gear, or add another Clarke BIP1000 Pump in series to double the outlet pressure & flow

Emtying & 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

When replacing elements in filter housings with screw-on bowls we always recommend the use of Silicon O Ring Grease to aid tightening of the bowl, preventing pinching & scuffing and thus prolonging the life of the O Ring

These vessels are supplied as standard with an NBR (AKA Nitrile / Buna-N) Top Seal, which will swell when used with Bio Diesel, we therefore always recommend you purchase a replacement VITON O'Ring which is resistant to Bio Diesel
