Tigerloop ®

The new Tigerloop ®The worlds leading automatic oil de-aeratorAFTER SEVERAL YEARS OF DEVELOPMENT, Tigerholm is proud to presentthe new third generation oil de-aerator, a unique invention known worldwideas the Tigerloop ® . With over 30 years experience and Tigerloop ® installedin more than 3.5 million heating oil systems around the world,Tigerholm has the experience and competence to further develop theworld’s best oil de-aerator. The new Tigerloop ® contains an increased capacityfor oil de-aeration. It meets present and increasingly tougher futuredemands for environmental safety, cost savings and reliability. To meet theincreasing demand from environmental regulations, Tigerloop ® improvesoil-heating installations by providing clean, air-free oil to the burner, whichreduces to a minimum the discharge of harmful particles. The newTigerloop ® also has an extra security chamber totally preventing the leakageof oil and thus raising safety to the highest level.OIL IS THE WORLD’S MOST IMPORTANT source of raw energy. It answersfor the largest production of energy and will be, for many years to come,very important for the production of heat. This puts a heavy responsibilityon the modern oil heating industry to develop efficient and environmentallysafer products. Recent development has lead to low-sulfur heating oil,highly efficient burners using blue-flame technology and condensing oilboilers. This new technology helps ensure optimal combustion making oilheating a reliable, cost effective and environmentally friendly alternative.These technological developments have created an even higher demandfor clean, air-free oil to ensure reliability in oil heating. The material selectionin every part of the new Tigerloop ® meets the demands placed by newoil qualities with special additives for lasting reliability.NEW LAWS AND REGULATIONS for environmentally safe oil heating installationsare leading to the demise of the two-pipe system. Tigerloop ®makes a one-pipe system possible for every type of oil heating installation.The one-pipe system is the most environmentally safe method for transportingoil from the oil tank to the oil burner. A number of Europeancountries have identified the risks associated with two-pipe systems andeven past laws forbidding its use.

Oil heating problems......with gas/air in oilWhen oil is drawn up from the oil tank to theburner large amounts of gas bubbles can be releasedfrom the oil. These gas bubbles are releasedwhen there is a negative pressure (vacuum) in thesuction line. This occurs in almost every installation,but above all when oil must be lifted to ahigher level, drawn through long suction lines orwhen the suction line is too coarse for the neededoil flow. Air can also enter the suction line if allconnections are not 100% tight or if the tank is runempty. The gas/air bubbles flow with the oil into theoil pump and are the leading cause of breakdowns,increased build up of soot, unnecessary wear andtear on the oil pump and higher oil consumption....with two-pipe systemsThe two-pipe system was developed to try and getrid of the gas/air bubbles from the oil pump.A return line pumps the separated gas/air bubblestogether with the unburned oil from the oil pumpback to the oil tank. This, however, does not reducethe amount of gas/air bubbles that flow to thenozzle for combustion, which leads to an air pocketforming between the oil pump and the nozzle. Thisair pocket causes dripping from the nozzle eachtime the oil burner is stopped resulting in increasedsoot build up and poor fuel efficiency. The high flowof oil in the two-pipe system (up to 20 times morethan what is actually used for combustion) leads toincreased dirt/sludge being released from the oiltank leading to clogged oil filters and nozzles. Thepressurised return line in a two-pipe system is thenumber one cause of leak damages. Even thesmallest leak in the return line can lead to terribleenvironmental damages and expensive clean up....with one-pipe system withoutTigerloop®The one-pipe system without a Tigerloop ® is not tobe recommended. This is due to the increased riskof breakdowns as gas/air bubbles cannot be removedfrom the oil pump during operation. Sucha system will only work as long as the oil is continuously100% free of gas/air bubbles. Moreover,it is impossible to automatically de-aerate thesystem during start up or after running the tankempty since a tool is necessary.Creating the optimaTigerloop ® makes a one-pipe systempossible for all types of oil heating installationshelping to ensure environmentalsafety, cost effectiveness and reliability.Effective de-aerationIn an oil heating system using a Tigerloop ® ,all oil passes through the automatic oil deaerator,which effectively removes all gas/airbubbles from the system. This eliminates oilpump and nozzle problems associated withgas/air in the oil.4213Own two-pipe circulationAn oil pump delivers the same amount of oilirrespective of what is actually needed for combustion.In the case of a normal domesticburner, only 5 % of the delivered oil is actuallyburned in combustion. The remaining 95% istransported by a two-pipe system back to the oiltank. With a Tigerloop ® automatic oil de-aeratorno oil needs to be transported back to the tank.The oil that is not burned in combustion is leadback to the Tigerloop ® where it is de-aeratedagain and again automatically. For this reasononly the amount of oil to be burned in combustionis sucked from the oil tank.

l solutionPreheated oilA one-pipe system with Tigerloop ® increasesthe oil pump capacity. Moreover, the oil isactually preheated to at least room temperatureas friction in the oil pump generatesheat. This eliminates problems with cold oilgiving cleaner combustion and reduced oilconsumption.5789101. Flexible oil hoses2. Tigerloop ® Plus3. Correctly dimensioned one-pipesystem4.

Tank filler pipeMinimum of dirt/sludgeThe oil flow in a one-pipe system is minimaldue to the fact that only the amount of oilburned needs to be drawn up from the tank. Forthis reason very little dirt/sludge is transportedfrom the oil tank. This reduces the risk for cloggedoil filters and burner nozzles. Filtration ismore effective, soot build up is reduced and filterlife is extended.!When converting from a two-pipe systemto a one-pipe system it is important toconsider the dimension of the suctionpipe (feed line). The suction pipe in atwo-pipe system is often too coarse asthe oil flow in a two-pipe system is up to20 times higher than a one-pipe system.Too coarse of pipe in a one-pipe system willlead to gas bubbles as siphon effect is lostin any descending sections of the suction line.For calculating the correct dimension suctionline and other details for the optimal installation,please refer to your local distributor.Information is also provided on our website atwww.tigerholm.com.

The new Tigerloop ®makes each installationeven more safe andefficientThe new Tigerloop ® comes not only with a new fresh appearance, but alsoan improved technical design. The reliable new design offers increasedcapacities while remaining the cost effective and environmentally safechoice.Oil de-aeration has been made even more effective thanks to a uniquedesign solution in the new Tigerloop ® . A patented float system has lead toan increase in de-aeration capacity from 6 to 8 l/h, which means air enteringthe system is more effectively removed.The superior de-aeration of the Tigerloop ® ensures that oil passingthrough the oil pump to the burner nozzle is completely air-free. Thisallows highly efficient combustion without dripping problems leading tosoot build up. A Tigerloop ® installation will achieve better fuel efficiencythrough lower oil consumption.The high de-aeration capacity together with a new patented anti-foamsystem ensures that oil will never leak from the Tigerloop ® even when, forexample, running the oil tank to empty.AS AN EXTRA SAFETY PRECAUTION an additional security chamber hasbeen designed in the new Tigerloop ® with a safety float. If somethingshould fail in the Tigerloop ® , oil will flow into the upper chamber causingthe safety float to seal tight. This raises the level of safety to an evenhigher standard ensuring that oil can never leak from the Tigerloop ® .
