Powerful centrifugal fans for universal use: The product ranges TEM and REM

Powerful centrifugal fans for universal use: The product ranges TEM and REM The fan ranges TEM and REM offered by Nicotra Gebhardt do present a large fan programme of single inlet centrifugal fans which are universally usable for many ventilation purposes either in HVAC or in machinery design industry and heavy duty installation business. The fans are available with forward curved impellers (TEM) or with impellers (REM) equipped with backward curved blades. The fans are equipped with IEC flanged (B5) standard s, protection IP55, class F, and they are suitable for frequency inverter controlled operation. Benefits: compact design because of direct drive cost effective by maintenance-free operation speed controlled by frequency inverter universally usable due to different options, such as without brackets as a directly fitted unit for operation with vertical shaft arrangement with brackets for operation with horizontal shaft ATEX execution for explosion hazardous areas and applications Fan range TEM rated - Ex II 3G c IIB T3 Fan range REM rated - Ex II 2G c IIB T3 264

Description Direct driven centrifugal fans / TEM/REM / Description Safety Performance data 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 121 "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 13857! Suitable safety guards are available as an optional extra. The performance curves of the fans are determined at the plenum test rig according to ISO 581, measured in installation "B". In the diagrams of all series, the total pressure increase and the dynamic pressure in relation to the flange crosssection at the discharge are represented in dependency on the. For closer determination of duty same unit performance curves (parabolas) are contained in the diagrams. The static pressure increase p sf with a connected discharge flange can be determined according to the following relation. p sf = All data are valid for the source density r 1 = 1,2kg/m³. Sound The noise measuring and evaluation is conducted according to DIN 45635-38 Noise measurement in machines: fans. In the diagrams the A-weighted sound power level of the fan is given on the performance curves as the emission. The A weighted sound power level are identical for fan intake (7 ) as well as for fan discharge (4 ). The A-weighted sound pressure level L pa7/6 at a distance of 1 m at fan Inlet or discharge can be approximately determined by the following formula: L pa6/7 ~ 4/7-7dB The sound power levels in the individual octavos can be taken from the electronic catalogue proselecta II. s Electric connection The series of centrifugal fans, with single inlet are designed for the use in air handling and ventilation installations. The fans are suitable for conveying air and other non aggressive gases. The temperatures admitted for the fluid are from -2 C to +6 C. Standard s of wellknown brands, type of protection IP55, thermal class F, are used. During commissioning and maintenance the detailed instructions provided by the manufacturer (type plate/ operating instructions) must be followed, this also applies to the protection devices required onsite. The s are equipped with PTC resistors/temperature sensors as standard. s with integrated frequency inverters may be supplied on request. The centrifugal fans are delivered ready for installation. The terminal box can be accessed easily. Electric installation must be carried out according to the applicable provisions in compliance with local regulations. A terminal board circuit diagram showing correct connection is enclosed with every. Updated circuit diagrams are also available online at www.nicotra-gebhardt.com. In case of operation with frequency inverters, always follow the respective operating instructions! 328

Description Direct driven centrifugal fans / TEM/REM / Description Explosion protection according to ATEX Fans for use in explosive atmospheres must comply with EC Directive 94/9/EG (ATEX 95). Equipment in Group II (all applications except mining) is categorised in accordance with the required degree of safety for designated use in equipment categories 1, 2 and 3. Depending on suitability, a distinction is in addition made between G (gas, vapours) and D (dust). Harmonised European standards and national guidelines must be observed. Equipment in class 2 and 3 is not subject to compulsory specifications nor to type testing. The manufacturer declares conformity with the EC directive. For the standard designs of our fans, the following ignition sources are essentially to be considered: Hot surfaces, e.g. due to heat of friction or seizure of a bearing or due to blockage of an impeller Rubbing-, grinding- or beating sparks, e. g. as a result of contact of the impeller with stationary components Sparks resulting from discharge of electrostatically loaded, non-conducting omponents, e. g. of plasticpanels, surfaces with strong layer thickness. Preconditions for operating: In the proximity of the, the temperature limits -2 C and +4 C must not be exceeded. The temperature limits of -2 C und +6 C for the medium must not be exceeded. If the temperature of the medium should exceed +6 C on the pressure side, then the fan must be switched off! The fans may only be employed with a horizontal shaft. The fans are to be protected against the falling-in or sucking-in of foreign objects. Protection guards must be ordered separately as an accessories. On the machine plate the max. permitted fan speed is indicated. Fans for operation in ex-hazardous areas are marked as such on the machine plate and they are accompanied by an EU conformity declaration and with operation and maintenance instructions The operation and maintenance instructions have strictly to be observed. 329
