General Technical InformationVersionsFlexit air handling units are available in thefollowing versions:- horizontal unit (L). Fitted with connectionnipples at the end for installation in technicalrooms, for example.contamination in the extract air will always betransferred so that it is necessary to be selectivewhen using this recovery technology.The temperature efficiency is approximately75-85%.Outdoor airSealing strip- cabinet unit (S). Fitted with connection nippleson the top for installation in small technicalrooms, for example.The units meet the requirements in EU Directives89/336/EEC and 73/23/EEC.Exhaust airCleaning sectorExtract airSupply airUnit type LUnit type S2. Cross Exchanger(Recuperative)The cross exchanger is a cassette that consistsof a row of aluminium plates. Recovery takesplace as follows:Recovery SystemsFlexit uses two different recovery technologies:1. Rotor2. Cross exchanger1. Rotor (Regenerative)Flexit uses a non-hygroscopic rotor. i.e. the rotordoes not actively emit moisture into the supplyair. This form of recovery takes place as follows:The rotor is a wheel that has a mass of aluminiumwith many ducts. This wheel rotates so thatthe mass absorbs heat from the extract air andtransfers the heat to the supply air. The rotor isdriven by a belt and a motor.Unlike the cross exchanger, the rotor technologyhas no practical problem with condensation andicing up. Therefore drainage is not required.The extract air and supply air exchange heaton separate sides of the aluminium plates. Thehot extract air heats the aluminium and thecold outdoor air then absorbs the heat. As theair flows pass on separate sides of the plates,the extract air and the supply air will neverbe in contact with each other. On accountits properties, this form of recovery involvesminimal transfer of contaminants, which, in turn,means that it can be used in a wide range ofapplications.Using a cross exchanger, moisture maybe condensed out of the extract air. Thiscondensation must be drained away.The temperature efficiency is approximately60-70%.Extract airThe internal pressure ratio in the unit is designedso that transfer of contaminants from the extractair to the supply air is minimal. The rotor has acleaning sector that functions in such a way thatthe rotor mass is “cleaned” with fresh air beforeit supplies its heat to the supply air.

To prevent the exchanger from icingup, Flexit has solved this problem with thedevelopment of the patented thermoguardand can guarantee operation under all climaticconditions including severe cold.InstructionsAll systems are supplied with detailedinstructions covering installation, use andmaintenance.FLEXIT S3 X/TT - A3 X/TTS4 X/TT - A4 X/TTS7 X/TT - A7 X/TTBrukerveiledningLuftbehandlingsaggregatSkapmodeller med varmegjenvinningProperties and Function ofthe ThermoguardTa vare på denne veiledningen for fremtidig brukThe thermoguard is placed inside the crossexchanger at the coldest point and monitorsboth temperature and humidity.There is a risk of frost when:1. Both humidity and cold are present2. The outdoor temperature conditions mean thatthere is a risk of dry ice in the exchanger cassette.Calculation ProgramA program for air handling unit calculations withtechnical data such as sound, air, power, SFP, etc.Deicing can be guaranteed by using a preheater.During deicing, the automatic control will reducethe air flow rate if the preheater is not able tomaintain the temperature in the cassette.Compared with traditional frost monitoringsystems (which switch off the supply air fan at +1°,regardless of whether humidity is present or not),Flexit’s solution saves a lot of energy as the unit isnot operated unnecessarily in bypass mode.Extract airOutdoor airTemperaturesensorEnvironmental ClassThe units’ chassis are produced in surfacetreatedsheet steel which meets environmentalclass M2, which covers indoor installation withnormal humidity impact and normal content ofair pollution.Cross exchangerSupply airExhaust airThermoguardCross exchanger with thermoguardEE RegulationElectrical products come under the regulationrelating to scrapped electrical and electronicproducts and are, in this connection, subject toan environmental tax.

General Product DescriptionProduct DescriptionFlexit air handling units are designed to provideoptimal air comfort combined with low energyconsumption. The heated, used indoor air isextracted via extraction valves from the rooms,passes through a filter and is introduced intothe unit’s cross heat exchanger before beingconducted out of the building via a roof hat orwall outlet.Outdoor air is introduced via an outdoor airintake to the unit, is filtered, passes through thecross heat exchanger and absorbs a large partof the heat from the extract air.The extract air and supply air pass each other inthe exchanger cassette in completely separateducts without the clean air being “infected” bythe used, contaminated air. The thermostatcontrolledheating battery ensures a draughtfreesupply air temperature. After the unit, thesupply air normally passes through silencersbefore flowing in through the supply air valves,fresh, clean and tempered.Flexit air handling units are fitted withelectronic automatic control.Area of Use, Horizontal UnitsFlexit horizontal (L) air handling units aresuitable for homes for installation in the loft.These aggregates are only supplied with crossexchangers.both sides. This makes it easy to position theunits in relation to duct connections (right andleft model in one). Small building dimensionshave been the aim.Area of Use, Cabinet UnitsThe Flexit vertical (S) cabinet version can beused to advantage for schools, nursery schools,offices, shops, homes, etc. The cabinet and thecompact design mean that the units can beused in both new and existing buildings. Theseunits are supplied with both cross exchangersand rotating exchangers.Design (S)The units are produced in sheet steel, whichresults in a robust, stable construction. Thewalls are made of double-cased galvanisedsheet steel with thermal and acousticinsulation. The connection bosses are on thetop. Externally, the units are lacquered white.All joints are sealed to eliminate the risk of airleakages. The units are fitted with two hingeddoors in the front which allow easy access forinspection/service.Design (L)Flexit air handling units are produced in strong,galvanised sheet steel, which produces a stable,robust construction. The units are double-casedwith an intermediate 50 mm of rock wool, whichproduces good thermal and acoustic insulation.All joints are sealed to eliminate the risk of airleakages. The units have inspection doors onHeat Recovery PrincipleCross ExchangerThe cross exchanger is made of aluminium. Theheat exchanger is designed with secure sealingagainst the various air chambers and can easilybe removed for cleaning and inspection. A unitwith a cross heat exchanger requires a drainagesystem for condensation water.10

General Product DescriptionSummer CassetteA summer cassette is available as an accessory.This can be used to replace the heat exchangerduring the warm part of the year.FansSingle-suction radial fans with bent-forwardblades. The fans have a high capacity, evenwith long duct sections, and have a low noiselevel. The fans are driven by a ball bearingmountedouter rotor motor of the highestquality. The motor, which is located in the fanwheel, is cooled very well. The fans can easilybe removed for cleaning (“click” electricalconnection).Rotating Heat ExchangerFlexit cabinet units can be supplied with rotatingrecovery. The rotating heat exchanger is a nonhygroscopicaluminium rotor which is mounted ina cassette. The entire cassette can be removedfrom the units for service and cleaning. The rotorwheel is mounted with maintenance-free dusttightball bearings.The rotor is driven in sequence with the heatcontrol by an electric motor via a drive belt.FiltersThe units are fitted with F7 filters on both theintake and extract air sides. The F7 filter stops97% of all particles greater than 0.5 my (1 my =1/1000 mm), i.e. pollen, dust from combustion,etc. This is a valuable property, in particularfor allergics and people with respiratory tractproblems.The filters are located in rails and are easy toreplace.HeatingIn order to ensure that the supply air has thecorrect temperature, the units are fitted withheating. This is available in the form of electricheating elements or water batteries.The water batteries are controlled by a 0-10V output which controls a 2-way or 3-way valve.11
