Air in system watercauses many problems.1 1 /4" JuniorNoisy pipes, valves and otherair-related system noises areoften accepted as the signs ofa functioning system. Excessivepump noise, cavitation andcascading water in terminalunits are considered normal.But....Serious problems can occur.Air in system water can causecorrosion, reduced efficiency, poorlyheated or inadequately cooledrooms, accelerated componentwear, and ongoing complaints.3/4" Junior Vertical2" Senior ThreadedResult:Unnecessary maintenance costsand a dissatisfied owner.There is a solution!A system without air-relatedproblems is possible! There is adevice that will keep your systemfree of air, permanently.

THE CORE EXPOSES THE DIFFERENCESThe principal differenceSPIROVENTThe Spirovent’s unique constructionallows not only for the removalof entrained air, but also for thecountless microbubbles. Consistingof a woven copper wire configurationsoldered to a copper tube, thepatented Spirotube ® creates a lowvelocity area in the Spirovent thatscrubs the bubbles from the water.The air bubbles rise and collect in theair chamber before they are ventedfrom the system via an integralautomatic valve. Air problemsbecome a thing of the past!5. The automatic air vent isguaranteed not to leak and canonly be closed by the installerfor a pressure test.1. Lifting eyes makeinstallation easy.6. The air chamber has beendesigned so that dirt cannotreach the valve.2. Welded steel constructionguarantees long life.7. Valve for releasing largeamounts of air duringfilling and for skimmingoff floating dirt.3. The unique Spirotube is thecore of the Spirovent.Designed to trap the smallestmicrobubble yet it offers littleresistance to flow.4. Drain plug. Also suitablefor connecting a valveor temperature sensor.8. Threaded or flangedconnections available.Threaded 3 /4"- 4"Flanged 2"and upP E R M A N E N T L Y A I R F R E E S Y S T E M W A T E R

SpirotopADVANTAGES TOTHE SPECIFIER,INSTALLER ANDOWNER■ Greatly reduced initial filland start-up time■ No venting required■ Optimum heat transfer■ Increased component life■ Reduced oxygen-basedcorrosion and pump cavitation■ Quiet operationThe Spirotube makesthe differenceThe Spirotube is the core of theSpirovent. It allows the Spiroventto scrub out 100% of the free air,100% of the entrained air, andup to 99.6% of the dissolved airin the system. Even the smallestmicrobubbles coalesce and rise.Air is eliminated, component lifeand heat transfer abilities areincreased; oxygen-based corrosionand pump cavitation are reduced;and annoying gurgling, cascading,and other air-related systemnoises are eliminated.CirculatorAcceptable locationfor circulator andexpansion tankBaseboardSpiroventBoilerCirculatorRecommended locationfor circulatorandexpansion tankInstall the Spirovent foroptimum performanceIdeal placement of the Spirovent is based on microbubbleseparation and Henry’s Law. Simply put, Henry’s Law statesthat air is released from water as the temperature increasesor the pressure decreases*. For this reason, the Spirovent istypically installed in the hottest point in the system. For aheating installation, this is in the supply from the boiler.In a chilled water circuit, the warmest point is in the returnto the chiller.SpirotopAir HandlerSpiroventCirculatorChillerExpansionTank*For more detailed technicalinformation, ask about ourSpirotism booklet .The patented Spirotube,the core of the SpiroventP E R M A N E N T L Y A I R F R E E S Y S T E M W A T E R
