BAND HEATERS WITH CERAMIC INSULATION-1

RISCALDATORI A FASCIA IN CERAMICA 5 RISCALDATORI A FASCIA IN CERAMICA Costituiti da una spirale in NiCr 80/20 alloggiata in elementi modulari in steatite. Il Carter esterno è in lamiera ALUSI o in acciaio inox. Sono adatti a temperature di funzionamento fino a 600°C e supportano carichi specifici fino a 8 W/cm2. Al fine di limitare la temperatura del carter esterno e di orientare il flusso termico verso la superficie da scaldare, la fascia è schermata con uno spessore isolante in fibra ceramica. BAND HEATERS WITH CERAMIC INSULATION Made from a NiCr 80/20 spiral insulated on steatite cares; the external casing is made from either aluminated sheet or stainless steel. The band heaters are suitable for operating temperatures up to 600°C and capable of withstanding specific power up to 8 W/cm2. In order to reduce the temperature of the external case and to direct the thermal flow towards the application surface, the band heater is shielded on the outside with a ceramic insulator. CARATTERISTICHE / TECHNICAL FEATURES APPLICAZIONI / APPLICATIONS Queste resistenze sono prevalentemente impiegate nel settore delle materie plastiche per il riscaldamento di presse ad iniezione, estrusori e soffiatrici. Ceramic band heaters are mainly used in the plastics industry for heating of injection moulding machines, extruders and blowing machinery. Meccaniche/ Mechanical Specifications Diametro/ Diameter Larghezza/ Width Min. 50 mm Max 500 mm (per diametri superiori ai 500 mm esecuzioni a SETTORI) (for diameters over 500 mm ASSEMBLING executions) Min. 30 mm Max correlata al diametro richiesto / Max width depends on the required diameter Circa 12 mm (9 mm di nucleo e 3 mm di isolante) / About 12 mm (9 mm of core and 3 mm of insulation) Luce/ Clearance Le fasce prevederanno, una volta serrate, una luce standard di ca. 5 mm. È consigliato l’utilizzo di una chiave dinamometrica per fissare le viti a 7-8 Nm The bands, once tightened, allow a standard clearance of about 5 mm. The use of a dynanometric wrench is suggested for fixing the screws at 7-8 Nm Elettriche/ Electrical Specifications Tensione/ Voltage Da 12 a 500V (possibilità di alimentazione trifase con predisposizione per collegamenti a stella o a triangolo) From 12 to 500V (with the possibility of using a triple pole voltage supply and combining it to a star or delta connection) Potenza/ Output Carichi specifici fino a 7-8 W/cm2 per particolari condizioni. Tolleranza standard secondo norme VDE a +5% -10% Specific power up to 7-8 W/cm2 in particular conditions. Standard tolerance in accordance with the VDE norm at +5% -10% Ampere-fase/ Ampere per phase Fino a 40A per alimentazione secondo i diversi tipi di connessione Up to 40A for each supply depending upon the various types of used connections PLASTICS Spessore/ Thickness 11
