In specialcases, such as the presence ofcorrosive parts, the aluminium can becoated with anti-corrosion paint, while,in thecase of high operatingtemperatures or special applications,stainless steel alloys are used.Condensation.Plate-type exchangers do not allow forthe passage of humidity from one flowto another, but can transfer part of thelatent heat contained in the wetexhaust air-flow; this happensespecially when external temperaturesare very low, so that the supply aircools the wet exhaust below its dewpoint and condensation is formed.Introduction2It is Recuperator's constant aim tomaintain the highest standards ofquality. Stated performance figures arecertified by tests carried out inaccordance with Eurovent rules byindependent organizations such asTechnikum of Lucerne (Switzerland)and Istituto Ricerche e Collaudi Masiniof Rho (Milan).The quality and performance ofRecuperator products are guaranteedby a well-equipped research laboratoryand an ASHRAE wind-tunnel, wheretests are conducted periodically onproduct lines.All supplies of aluminium coils arechecked and tested using our Erichsentest equipment, in accordance with DINStandard 50 101. Checks are repeatedduring and at the end of themanufacturing process so that thephysical characteristics of the materialsused are continuously monitored.QualityAir-conditioningVentilationAreasSchoolsSwimming-poolsHospitalsTelephonyRailwaysVentilation hoodsDryersRotogravure printing machinesHeat recovery from flue gases3Material SeriesThe table gives a few examples ofapplications relating to series andmaterials used by Recuperator.Pre-heating and pre-cooling in the air-handling unitsApplicationBFAluminiumHeat recovery from air renewal (B Aluminium) B AluminiumPre-heating of air in air-handling units BFCoated aluminiumHeat recovery from the exhaust air withoutmixing of the two air-flowsBFAluminium and stainless-steelHeat dissipation inside shelters and mobiletelephone cabinsB B Aluminium and coated aluminiumHeat dissipation inside converters for air-conditioning in railway carriagesBFAluminiumHeat recovery from flue gases for heatingpremisesBFB Aluminium and coated aluminiumPre-heating of air inside dryers and heating ofpremisesBFAluminium and stainless-steelHeat recovery from solvents and heating ofpremisesBFAluminium and stainless-steelHeat recovery for pre-heating the air at entranceto burners and heating of premisesBFStainless steelExamples of Applications407=Modelfrom 02 to 24AL= Plate materialAL: AluminiumAC: Coated aluminiumI6: AISI 316LN=Temperature rangesN: -30C+90C polyurethane/epoxy resinD: -30C+150C silicon/epoxy resinV: -30C+200C silicon/epoxy resinX: -30C+280C siliconY: -30C+500C refractory siliconF=SeriesBFx=Trading groupT=VersionT: StandardS: Stock cubesSC BP25=Options090= Net length of finned unit(cm) (step 10 mm)M=Spacing between platesC: Close-fittingM: MediumL: LargeProduct CodeFxAL07N090MTSCBP25general informationfor specifications see Page 8SC SMNSTVXS AZCPCSRFby-passfor specifications see Page 9BSBPBZBCBABBBLBVBP..

SeriesRecuperator provides a series of By-pass options to meet various requirements. All the By-pass options are valid from Model03.BABy-pass Options10The air-flow direction is of no real importance. However, it is recommended that the exhaust air pass through the heat-exchanger from the top towards the bottom in cases in which the formation of condensation is to be expected.Some examples of the behaviour of the two air-flows, using a single heat-exchanger.In special cases, it is possible to use several heat-exchangers to overcome inconveniences such as: lack of space, a majordifference between the two flows, etc. The drawings show a few examples.Special Applications1107081012Aluminium and coated aluminiumGeneral tolerances: UNI ISO2768 cSeries BModel0203040506AmmMax 700Max 900Max 1200Max 1300Max 1400A1mmA+2CA+2CA+2CA+2CA+2CBmm140240340440540B1mm200300400500600Cmm2020202020Dmm3030303030Series F[RF]ModelAL/ACAmmMax 3000Max 3000Max 3000Max 3000A1mmA+2CA+2CA+2CA+2CBmm6407409401140B1mm74084010401240Cmm50505050Dmm50505050NB: Option PV:A = max 500 mmOption AZ:A = max 700 mmAL/AC0607081012Series FModelAmmMax 1500Max 2400Max 2400Max 2400Max 2400A1mmA+2CA+2CA+2CA+2CA+2CBmm5196197199191119B1mm60570580510051205Cmm2030304040Dmm4343434343AL/ACDimensionsNB: Option CP: A = max 1700 mm12Aluminium and coated aluminiumSeries FModel14162024AmmMax 2400Max 2400Max 2400Max 2400A1mmA+2CA+2CA+2CA+2CBmm6197199191119B1mm1410161020102410Cmm30304040Dmm43434343Series F[RF]Model14162024AmmMax 3000Max 3000Max 3000Max 3000A1mmA+2CA+2CA+2CA+2CBmm6407409401140B1mm1480168020802480Cmm50505050Dmm50505050General tolerances: UNI ISO2768 cAL/ACAL/ACNota: opzione CP: A = max 1700 mmNB: *= Min 100 -

Itshould not be removed until the timecomes to connect the heat-exchangerto the air-ducts or install it in the air-treatment units, thus avoiding anysoiling or damage of any kind.When starting up the plant, care shouldbe taken to avoid "water hammering"which could cause a higher differentialpressure than that allowed, withpossible damage to the heat recoveryunit. Care should also be taken to avoidforeign matter (rubble, paper, etc.)being sucked into the system. It istherefore recommended that the air-ducts be cleaned before installation, ora temporary by-pass around the unitset up, or provisional filters be fitted.Installation.The heat-exchanger may be installed inair-ducts, or else inside an air-handlingunit. It is important that the platesshould be set vertically, to facilitate thedraining of condensation. In the air-handling units, the heat recovery unit islodged on proper slides and the sealson supports (see Fig. 1), made easierby the use of rubber weather bands.1Instructions Aluminium Version20Duct installation is illustrated in Fig. 2.Heights, indicated by the letter A (35mm for Series F; 8.5 mm for Series B)represent the space required fordrilling; the heights indicated by B (30mm for all series) indicate the spacewithin which no drilling may be done(Fig. 2/a, 2/b). Models 14, 16, 20, and24 are obtained by coupling 4 individualelements. This work is carried out atour workshop.The exhaust air, which may producecondensation or frost during the winter,should preferably enter the heat-exchanger from above.The condensation will be collected inthe lower part of the duct or of the air-handling unit, where it will be advisableto provide a discharge systemequipped with a siphon.In installing plant with a by-pass it isadvisable not to fix ducts directly on thedamper.Maintenance.Recuperator units have no movingparts, so mechanical maintenance isnot called for. To deal with dust orpollutant substances, it will benecessary to provide adequate filtersupstream of the heat-exchangers.Units may be cleaned with compressedair (in the case of dusty surfaces), atthe same time taking care not todamage the plates and seals, or elseby using a detergent spray (e.g.,Decade, ND-150, Chem Zyme,Primasept, Poly-Det, Oakite 86M or thelike) to remove greasy deposits.Strongly alkaline or other substancescorrosive to aluminium or the sealshould obviously be avoided.NB: In countries subject to sandstorms,it is necessary to provide sand filtersplus high-efficiency pouch-type filterson the external air-intakes.22 aSeries BSeries F2 b21Instructions on transport and assemblyof Series B and F.Packaging.The packaging of Series B and Fconsists of a pallet-type base and threewooden panels fitted on the equipmentwith a strap.Preliminary Inspection.Before removing the packaging it isadvisable to check that the heat-exchanger has not been damaged intransit; careful visual checking shouldbe enough to ensure that thepackaging is in good condition.
