Cartridge | <strong>Filtration</strong>Twist-LOK Filter Series ProvidesVersatile Phase SeparationBy Mike Click, Marketing Director, Jonell Inc.Twist-LOK's elements, showing first stageidentified by color code blue end caps andsecond stage on the left, identified by colorcode white end caps.22 • August 2013 • www.filtnews.com<strong>Filtration</strong> plays a key role in notonly protecting society fromcontaminants but also protectingindustrial equipment as well byseparating fluid and particles or separatingdifferent chemical types of materials.As a result of today’soperational complexities, industry filtrationequipment demands havegrown increasingly more sophisticatedto meet the challenges.A phase separation filter must beboth capable of seamless performancein wide-ranging conditions in themidst of even the harshest environments.A premier solution has arrived,with the introduction of Twist-LOKFilter Series’ versatile separation systemfrom Jonell, Inc. This innovativeproduct delivers superior contaminantremoval and coalescing efficiency, plusthe patent-pending Twist-LOK lockingmechanism.Twist-LOK’s major feature is its twopiecedesign, allowing real-time fieldcustomization and the ability to replacethe first stage filter element withouthaving to also replace the second stagecoalescer element. Also, Twist-LOK isdesigned specifically for installationinto Peach® Gemini PuraSep® vessels.BREAKTHROUGH NATURAL GASTwist-LOK’s revolutionary design accomplishesmultiple objectives in doingits job. This filter optimizes flexibilityand reliability while it processes highliquid loads with exceptional particulatehandling. Specifically for the energyindustry, which has always been in theforefront of innovative technology,Twist-LOK’s first and second stage applicationsare designed to remove liquidand solid contaminants from natural
and process gas.Its assembled cartridge provides aStage 1 “outside to inside” flow directionfilter element and Stage 2provides the reverse “inside to outside”flow coalescer element. Withinthis process, a new feature providessavings not available with other cartridges.With other filtration/coalescingelements, it was necessary toreplace both stages, which oftenmeant wasting a clean Stage 2 element.With the new Twist-LOK FilterSeries, however, users can optionallyreplace and optimize Stage 1 with noneed to replace Stage 2, a bonus forcompanies that appreciate opportunitiesto take advantage of savings intheir operations.EXCEPTIONAL VERSATILITYAll Twist-LOK cartridges offer exceptionalversatility by including, forinstance, an extensive listing of optionalfilter and coalescing combinations.These can be readily customizedby users to adapt to individual processapplications.In a relatively short time, Twist-LOK’s two-stage phase separation –actual filter element in the first stagefor the “outside to inside” gas flowand coalescer element for the secondstage’s “inside to outside” gas flow –has changed how filtration purchasersview this type of product. Insteadof having to determine howcompetitive system components worktogether to accomplish the desiredtask, more and more companies havereadily taken to the Jonell motto:Quality filtration made simple.Twist-LOK and many other industrialproducts, from gas and liquid filtersto filter vessel internals, aredesigned and manufactured by Breckinridge,Texas-based Jonell, Inc.,which was founded in the 1980s expresslyto provide quality filter elementsto the oil and gas industry.Building on its continuing growth inthe filtration market, Jonell offers numerousfilter options, both pleatedand depth style, in an equally largemedia selection that encompassesevery application and compatibility requirementin the oilfield.STAGE 1 APPLICATIONFirst Stage elements in Twist-LOKessentially pave the way for the SecondStage to operate most effectively.Through Stage 1 removal of solid andsemi-solid particulates and pre-coalesceliquids, Stage 2 functions withmaximum performance and minimalflow blockage over an extended periodof time.In Stage 1, media include Tri-DEP TM ,micro-fiberglass, polyester, polypropylene,cellulose, cotton and the productis custom-engineered. Jonell’s trademarkedTri-DEP media fiber extrusionprocess has proven the value of its fiberextrusion process. This unique processutilizes synthetic trilobal fibers, whichprovide increased void spaces for contaminantretention whereas traditionalcircular fiber media are comparativelylacking in this respect. With real workhorsecapabilities, Tri-DEP media’savailability in both polyester andpolypropylene provides exceptional mechanicaland chemical resistance in avariety of applications.www.filtnews.com • August 2013 • 23STAGE 2 APPLICATIONWith Stage 1 effectively clearing theway, Stage 2 elements have been designedas ultra-high efficiency coalescersthat consistently removesub-micron low-surface tension liquids.Similar to Stage 1, Jonell offers numeroushigh-efficiency Stage 2 coalescer elements;ideal for every application, theseare available in pleated, depth and customcombination styles. In Stage 2, thecustom-engineered product's media includeTri-DEP micro-fiberglass, polyester,polypropylene, cellulose and cotton.IMPRESSIVE FEATURES/BENEFITSAs would be expected from a companywith Jonell’s design and manufacturingcapabilities, features andbenefits of the Twist-LOK Filter Seriesare many, built around its specificdesign for Peach GeminiPuraSep installation. Among theforemost is that the system allows replacementof first stage filter elementswithout removing the secondstage coalescing elements from the
