Working towards perfection The ADH E and ADH series By further developing sizes 0160 to 0560 of our successful ADH model range, we have created a product series which boasts a whole host of improvements. The result is the ADH E generation, one which will overcome the challenges of any application. During development, we paid particularly close attention to four factors: air volume flow, pressure, energy efficiency and noise. These aspects are the key to success: all of the models are on a par with or superior to their predecessors in terms of these parameters. New choice of models Whether you are looking for single or twin fans, the new ADH E series offers impressive further improvements in terms of functionality and potential uses, whatever the application. The ultimate in compatibility Minimised design effort for you means that: All accessories and equipment are carefully coordinated and compatible to further product ranges like RDH E / RDH (backward curved centrifugal fans) and RZR (hollow-airfoil blade geometry). The connection dimensions for ADH E (sizes 0160 to 0560) are identical with the corresponding models from the ADH range. The models for sizes ADH 0630 to 1000 remain unchanged. All ADH E models up to size 00 are compatible with the new compact base frame a unique feature which makes completing your system ultra simple and affordable! Top quality for performance and a long service life! Alongside an intelligent construction, aspects such as the quality of materials and workmanship play a crucial role in ensuring a long life cycle. That s why we have made the casing of the new ADH E even sturdier by means of a standing seam construction. In addition to this, the way in which the blades are attached to the impeller has been optimised and the shafts have been galvanised for more effective corrosion protection further factors which significantly increase the service life of this range. 4

Fittings / Accessories Belt Driven Centrifugal Fans / Fittings and Accessories Volumeter p in With the flow measuring device it is possible to easily measure/monitor the flow rate after the fan is installed. A pressure tapping at a predetermined position on the inlet cone is provided whereby the differential pressure in relation to the static pressure is measured in front ofthe inlet cone in a static atmosphere. Permissible media temperature: +0 C (RZR), +70 C (RDH). q V = K 2 p Dü Measuring connector in inlet cone Hose pipe to connecting piece in the side wall Connecting piece (external diameter of 6mm) for the pressure measurement In order to calculate the flow rate, a calibrating factor "K" is required. This factor is determined by comparativemeasurement on a standard test rig. Standard-calibration faktor K Where fans are built into a plenum, the pressure difference between the static pressure in the inlet side plenum and the pressure on the inlet cone is to bemeasured. It must be ensured that the static pressureto be measured in front of the inlet cone is not tampered by dynamic pressure fractions. It is often recommended to arrange a ring of points on the wall facing the outlet side as illustrated in the sketch. When using the K factors specified below, a minimum clearance of 0.5 D between the inlet cone of the fan and the side wall of the plenum must be maintained. Indentations that obstruct the flow to the cone canlead to faults when measuring the flow rate. In the event that the differential pressure is fed via a pressure sensor, the signal can also be used for regulating purposes. p in A volume flow q V [m³/h] A calibration factor K [m²s/h] A density of media r [kg/m³] A pressure difference at cone Dp Dü [Pa] Calibration factors Type IMV 13-0200 100 IMV 13-0225 5 IMV 13-02 1 IMV 13-00 165 IMV 13-0315 190 IMV 13-0355 235 IMV 13-00 290 IMV 13-04 360 IMV 13-00 460 IMV 13-0560 560 IMV 13-0630 730 IMV 13-0710 960 IMV 13-000 0 IMV 13-0900 14 IMV 13-1000 1 IMV 13-20 20 IMV 13-12 3000 IMV 13-10 300 IMV 13-1600 4700 Standard calibration factor K m²s/h Inlet Cones Inlet cone of copper or aluminium prevent the production of sparks during operation.

Fastening for CC-profile Fastening for U-profile AV mounts should be mounted beneath the fan base frame so the weight and spring deflections are evenly distributed. They should not be mounted symmetrically because a counter force is induced into the system by the pressure created by the working fan. It is difficult for the manufacturer to establish the position of the AV mounts to suit all types of application. Vibration and noise insulation can also be improved by ensuring that the fan is connected to its external environment by a flexible coupling. Rubber pads and buffers for both vibration and noise insulation at fan speeds above 10 rpm or rpm. Rubber buffers for noise insulation only at fan speeds under 00 rpm or 1700 rpm. Spring diffusers with noise insulation layer and height adjustment, for both vibration and noise insulation at fan speeds above 0 rpm. Available AV mounts for different fans, see proselecta II. The AVM-mounts are supplied with the suitable mounting material for the base frame.

Fan Sets Belt Driven Centrifugal Fans / Fan Set Base Frame with Belt Tensioning Device G2Z-component size 0200/-00 (only RZR /19) This compact base frame with integrated motor tensioning slider provides optimum compactness and easiest handling. A The base frame made of galvanized sheet steel is screwed directly onto the fan (without any casing feet) the result being the low overall height of the system. A The overall length depending on the casing position and size of the motor is a further factor influencing the optimum compactness. A The integrated tensioning slider considerably simplifies re-adjustment of the belt drive during maintenance and service work. G1Z-component size 00/-0710 The base frames up to motor size 10 are manufactured from galvanized CC-profiles. The anti-vibration mounts in the CC-profile provide infinitely variable adjustment. From motor size 200 the base frames are of U-profile, welded and painted. Fitted motor tensioning tracks that allow the motor to be shifted longitudinally, allow for the simple adjustment of the belt tension. G1Z-component size 000/-1600 Base frame of stable U-profiles, welded and painted, with holes for attaching the antivibration mounts. Fitted motor tensioning tracks that allow the motor to be shifted longitudinally, allow for the simple adjustment of the belt tension. Equipment A FKS hot-dip galvanized for U-profile base frame Pick-A-Back This allows the motor to be fixed directly onto the fan casing, where space around the fan is limited. One side of the pick-a-back is fixed to the casing so that it swivels, while the other is supported on a spindle. Thus the pick-a-back becomes adjustable to leave room for tensioning the drive belt. The various motor arrangements and casing positions are shown in the drawings. The accompanying tables also show the maximum permissible motor sizes. When using a pick-a-back arrangement and fitting anti vibration mounts (AVM) an additional base frame for fitting the AVM may be required depending on the position of the centre of gravity of the whole fan set. 59

Fan Sets Belt Driven Centrifugal Fans / Fan Set Belt Drive Wedge Belts High performance narrow V-belts in accordance with DIN 7753 are temperature stable up to +0 C, resistant to mineral oils and electrostatically conductive. The belt pulleys are made of high quality cast iron and, depending on the peripheral velocity and number of grooves, are statically (G 16) or dynamically (G 6.3) balanced. They are fastened to the shaft of the motor or fan by means of a clamping bush. Flat Belts The flat belt drives employed are made using the most modern technology and materials. They are the centrepiece of highly developed, powerful belt drives. This modern flat belt drive has distinct advantages over traditionally employed V-belt drives and exceeds it in efficiency, quiet running and economy. Overview of the advantages: A higher efficiency A longer service life A quieter running A easy to install A low maintenance A no wear on the belt - so it is possible to dispense with the 2nd filter stage in the air conditioning unit (in accordance with VDI 6022) Belt Guard Totally enclosed belt guards are made from galvanised sheet steel in accordance with DIN DIN EN ISO 1357. The front section can be removed for maintenance. If there is no standard belt guard available for the selected belt drive (see table), a suitable belt guard will be made as a welded construction and then coated.

Fan Sets Belt Driven Centrifugal Fans / Fan Set Min. Pulley-Diameter, Bearings Life Expectency As a principle, the fans are only equipped with noise tested precision bearings designed for a nominal bearing life time (L10h acc. to DIN ISO 1-1) of,000 operating hours. In order to not exceed the admitted bearing loads there are minimum pulley diameters defined to be respected when sizing the belt drive. The minimum pulley diameters indicated are to be applied for belt drives selected according to the state of the art and tensioned according to the prescriptions. For flat belt drives the minimum pulley diameters are to be increased of % to the indicated figure! A correct design of a belt drive may be achieved with our selection software where all relevant parameters will be kept automatically. For correct design of a belt drive made by external means, dimensioning and the application of the tensioning forces have to made in full respect of all specification data indicated. Wedge Belts L T L T = Shaft Centres b = Defection of belt in mm under test force F p Fp = Test force N as prescribed by Nicotra Gebhardt-Document L T /2 L T /2 Belt Tensioning The correct tension is achieved when the test force Fp results in a deflection of 16 mm / metre of span. b F p Flat Belts ε* L Mu L Mg L Mu = Measuring Marks 1 before Tensioning L Mg = Measuring Marks 1 After Tensioning e* = Stretching Values as specified by Nicotra Gebhardt-Document Belt Tensioning The correct belt tension is achieved when the measuring marks L Mu have increased by the stretching value e*. This should be carried out in two stages to prevent overstressing of the bearing. Wedge- and Flat Belts = = A further simple method for setting or checking the correct belt tension is via the static frequency of the drive belt. Here the flat or V-belt is set to oscillate freely through striking it whilst stationary. These vibrations are measured using an electronic measuring unit (e.g. a belt tension gauge). The vibration frequency in Hz must then be set to the specified value (documentation / nameplate). 1 = Measuring point Detailed instruction on tensioning are included within the operating and maintenance manuals. 71

Description Belt Driven Centrifugal FansBelt Driven Centrifugal Fans / Description General The high-performance centrifugal fans are the result of extensive and systematic development work. These technically first-rate products are distinguished by their high efficiency, the large pressure differences attainable and low noise levels. The sizes are geometrically scaled in accordance with the standard range R 20 and the nominal size stated is the external diameter of the impeller. Media The fans are suitable for handling air and other non aggressive gases from -20 C up to +0 C, resp. +100 C. The ambient temperature at the drive motor must not exceed + C. Protective installations The fans are designed for installation in equipment and as standard are not equipped with protective guards. They should not be put into operation before all protective devices are fitted and connected! Protective measures must be carried out as set out in DIN EN ISO 12100 "Safety of machinery - Basic concepts, general principles for design". If the application of the fan allows free access to the inlet and discharge apertures, safety devices must be put in place on the fan in accordance with DIN EN ISO 1357! Suitable safety guards are available as an optional extra. Shafts Shafts ADH / AT / RDH The fan shafts are manufacrured of ground, precisely rounded carbon steel C. They are principally prepared without being stepped at both ends. The shafts of the RDH K1 and K2 ranges, size 1000 are machined on both ends for fitting a pulley. ADH / AT from size 12/9 / RDH The shafts are equipped with a keyway (open shape) at both ends and a key (type 2). AT 7/7 up to 10/10 The standard construction is the version with flats on shaft ends (type 1), it is also available the version with keyways (type 2). For corrosion protection the shafts are galvanised up to fan size 0560 and 30/. From size 0630 and larger the shaft are covered, between bearing and hub, with a paint in order to ensure corrosion protection. The shaft ends are covered with a wax product easy to remove. Shafts RZR The shafts are manufacured of precisely rounded carbon steel C35, pared and polished. Up to size 1000 they are not stepped at the shaft end. For sizes 20 up to 1600 the shafts are machined on both ends for fitting a pulley. The shafts are equipped with a keyway at both ends and a key executed according to DIN 65-1. A Groove shape N2 (open) Sizes 0200 up to 1000 A Groove shape N1 Sizes 20 up to 1600 The shafts are covered with a easily removable wax product for corrosion protection.

Description Belt Driven Centrifugal Fans / Description Performance The curves show the total pressure rise p F as a function of the volume flow rate q V plotted in a double logarithmical diagram. The throttle curves (system resistance parabolas) are then represented by straight lines. The curves are established with a reference density of r 1 = 1.2 kg/m³ at the fan intake. The pressure and impeller input power are directly proportional to density r 1. Outlet velocity v 2 and the dynamic pressure p d2 refer to the flanged cross section area at the fan discharge. p sf = p F p d2 The increase in static pressure p sf when a duct is fitted to the discharge (Installation B) can be calculated from the equation: p sf = p F f pd p d2 Where no duct is fitted (Installation A) there is no static pressure regain. The increase in pressure p sf can be calculated from formula: The limits of application indicated in the fan curves (by blue dotted lines) outline the recommended functional range of the fans, where a stable operation with high efficiency can be expected. The efficiency marked on the straight system lines is only applicable at the maximum fan speed N max ; it decreases with lower fan speed.

The vertical scales shown at the right side of the diagram indicate the bearing power loss P b of the different fan executions and depending on the fan speed. The resulting power absorbed on fan shaft is found by adding the absorbed power P r of the fan impeller and the bearing power losses P b. As a consequence the resulting fan efficiency is to be calculated according to the formula: Efficiency RZR The actual efficiency value for a fan speed lower N max is calculated by multiplying the efficiency at N max by the factor f h for the appropriate speed. (f h to be found with the scale on the right side of the page). P N P a f P Motor nominal power ADH / AT / RDH / RZR To determine the motor rating P N, the fan absorbed shaft power P r must be increased by a safety factor to accommodate belt drive losses and possible fan speed differences. The factor f p is an estimated value. As an approximate value, the figures below are suggested.

Description Belt Driven Centrifugal Fans / Description Performance t A = J N² P N 10 6 When selecting the motor, the run up time must be checked whether being within permitted limits. The run up time can be worked out approximately according to the following formula: where: t A = run time in seconds J = moment of inertia in kgm² N = fan speed in rpm P N = nominal motor power in kw (Impeller weight and moment of inertia can be found on the performance diagram for each fan size.) If t A exceeds the motor manufacturer s recommendation or the tripping period of the electrical gear, a larger motor must be used or the starting gear has to be selected for heavy starting. 1 = Test fan 2 = Discharge duct 3 = Screen 4 = Multiple nozzles 5 = Auxiliary fan and damper Fan curves measurement ADH / AT / RDH - AMCA 210-99 / ISO 1 1 2 3 4 5 p e4 p e6 p 1 = Test fan 2 = Discharge duct acting as a pressure regain unit 3 = Screen 4 = Variable damper 5 = Compensating fan 6 = Flow straightener 7 = Inlet cone Fan curves measurement RZR - ISO 1 / DIN 24163 2 1 3 4 5 6 7 p a ta t 1 p sf q V = f(p o ) p o Performance data of twin fan units The performance data of twin fan units (Identification "G2") can be calculated, starting from that in the corresponding operating point of a single fan, with the following formulas: A Fan Pressure: p F G2 = p F 1 A Volume flow rate: q V G2 = q V 2 A Fan shaft power: P a G2 = P a 2,15 A Rotational speed: N G2 = N 1,05 A Sound: L WA G2 = L WA + 3 db AMCA Nicotra Gebhardt S.p.A.

Induct Method for the Discharge The induct method is specified with DIN EN ISO 5136. It determines the sound power emitted at discharge of a test fan. The test duct, as a main feature, is equipped with an anechoic termination fitted to avoid end reflection going back into the duct. Envelope Method Free Inlet The Envelope Method is described with DIN 45635-1 and -3, which specifies a hypothetical box shaped measurement surface with several prescribed measurement points. 1 = Air permeable sound screen 2 = Microphone positions for envelope method 3 = Test fan 4 = Measuring duct 5 = Microphone with sampling tube 6 = Anechoic termination 7 = Step less adjustable throttle 1 2 3 4 5 6 7 L p4 L p7 p sf The sound data of the fan curves are given as A weighted sound power levels. A-sound power level RZR The A weighted sound power level are identical for fan intake (L WA7 ) as well as for fan discharge (L WA4 ). L WA4 = L WA7 + L Wrel4 (A) A-sound power level ADH / AT / RDH The A weighted sound power level (see curves) are apply for fan intake (L WA7 ). The fan discharge sound power level L WA4 is obtained by calculating: The correction value DL Wrel4 (A) is found with the table (left below) at the corresponding fan curve page (ADH / RDH) by introducing fan speed and flow rate. ADH / AT / RDH: L Wfc7 = L WA7 + L Wrel7 L Wfc4 = L WA7 + L Wrel4 RZR: L Wfc7 = L WA4;7 + L Wrel7 L Wfc4 = L WA4;7 + L Wrel4 f BP = N z 60 An approximation of the A weighted sound pressure levels L pa7 /L pa6 at a distance of 1 m may be obtained by subtracting 7 db from the relative A weighted sound power levels. If should be noted that site acoustics, duct design, reverberation, natural frequencies etc. can all influence noise to a greater or lesser extent. For more accurate calculations to determine noise protection measures, the sound power level in each octave band is of more value: The noise correction data L Wrel4 und L Wrel7, in function of the fan speed and flow rate, are to be found with the corresponding table on the fan curve page. In some cases the noise level - calculated by this way - may in some cases be higher than expected at the blade passing frequency. f s = Blade passing frequency in Hz N = Fan speed in 1/min z = No of blades (see curve pages) 7
