<strong>ATLAS</strong> - HELIOS ConstructionHELIOSAtlas CasingThe main casing ismanufactured fromgalvanized prepainted steelfinished in dove grey, and isassembled from threecomponent parts. The steelis 1 mm thick and beingpainted before manufactureprevents the material beingsubject to oxidation. Thecomponent parts are heldtogether by snake proofscrews and moulded cornerselections to facilitate astrong robust box section.The adjustable louvres areheld firm by spring loadedpivots.Fourway distribution isachieved by the addition ofa second set of louvres tothe front of the unit, generallyfor downward application.Helios CasingThe main casing ismanufactured from 4 angulardiecast aluminuimcomponents and lateralelements made of extruded,anodized aluminium in silvercolour. The componentsparts are held together bysnake proof screws, theadjustable louvres are heldfirm by spring loaded pivots.Fourway distribution isachivied by the addistion ofa second set of louvres tothe front of the unit, generallyfor downward application.FanThe fan is of the helicoidaldesign with aluminium bladesstatically and dynamicallybalanced.It’s rational high-capacityprofile provides the maximumair minimum noise level andeconomical electricalconsumption. The fan hub issecured on the motor shaftby means of flat and grubscrew.4
Fan/Motor AssemblyThe fan and motor assemblyis made up of three components:the fan, the motor and thefinger proof guard, which alsoacts as the main support andfixing frame. This frame ismounted onto the main casingvia residually anti-vibrationrubber mountings. Return airclearance room necessary toavoid inefficient performanceis only the same as thatnecessary to remove theFan/Motor Assembly forroutine maintenance.MotorThe standard motor fitted isa hermetically sealed motorwhich is maintenance free.The motor is supplied asstandard for a three phase230/400 volt 50 Hz supply withthe field coils connected in starformation.With the introduction of asuitably sized capacitor andthe alteration of the field coilsfrom star to delta (as per thesketch on page 45), the motoris then capable of operating ona single phase 230 volt 50 Hzsupply.All motors are insulated toIP44 class B standard, butIP55 protection is available.Available also is ourflameproof motor for useon three phase supply only.These motors comply toCEI class II2GEExd IIBT4specification (1 speed motorsonly).The number of poles in themotor determins the speed atwhich the motor runs:4 pole motor runs at 1400 rpm6 pole motor runs at 900 rpm8 pole motor runs at 700 rpmMotor protectionWhen high pressure steamis used on downflowsystems the supply of steamshould be isolated when themotor is not running andclass H motor must be used.Failure to operate this systemwill result in the motor being“cooked”.PackagingThe units are packed intostrong corrugated cardboardcartons with strengthenedupper and lower side sections.These containers are clearlymarked with the unitreference.Fin 0,15 mmØ 22 mmPitch 2,5 mmThickness 1 mmHeat exchangerThanks to its heart Sabianais a Leader in the Sales ofUnit Heaters in Europe.The battery of Sabiana Atlasand Helios unit heaters withsteel tubes ø 22 mm andaluminium fins has thefollowing advantagescompared with the copperaluminiumsmall diameter tubebatteries used by most of ourcompetitors.The material used for the steeltube, which is very thick (1 mminstead of 0,3 - 0,4 mm),makes the Sabiana batteryextremely sturdy and longlasting.The tube big diameter reducesthe water pressure drop: thismeans that reduced powerpumps are installed and a veryrapid heating capacity isprovided.The Sabiana battery for unitheaters uses a reducednumber of tubes to give thesame yield: this determines alow resistance to the air flowand consequently an optimumleaving air temperature anda very high throw.The greater spacing betweenthe fins as well as theirthickness facilitate cleaningand maintenance operations,which is assential to keep theunit heater efficient.The steel tube battery is theideal choice for plants whereall tubes and equipment aremade of steel because itavoids physical and chemicalunbalance due to theinteraction of different metals.The special painting coatmakes the battery long lastingand increases the thermaloutput.The Sabiana battery can beused with hot water and hightemperature hot water with aworking pressure up to 16 barand with steam up to 10 bar.As a mattetr of fact eachbattery is submitted to twotests at 30 bars.However Sabiana in order tomeet any design andinstallation need can offer acomplete set of unit heaterswith cooper tubes andaluminium fins. This batteryhas the same features (tubediameter, fin pitch, etc.) of thesteel battery but it is built withcopper tube 0,7 mm thick, ofhigher quality and with a totalweight which is doublecompared with the batteriesnormally used for unit heaters.The wide range of productsincludes 10 different sizes with1, 2 or 3 rows each.5
