SEALED MICA STRIP HEATERS • Tailor made strip heaters. Max. watt density over the surface of the heater : 4 W/cm². Max. working temperature on the strip heater : 340°C. These parameters depend on the using recommandation and the connection type. Heaters available in 2 versions : - Encapsulated sealed mica strip heaters, -Sealed mica strip heaters, up to 90 mm large. Encapsulated sealed strip heaters : 20 to 90 mm. Sealed heaters : 91 to 215 mm. Width define with a multiple of 5 mm Thickness : Encapsulated mica strip heaters : 2.8 to 3 mm Sealed heaters : 3 to 3.2 mm Informations for a heater’s length< 1200 mm. Thickness without connection. Electric insulation with mica. Connection : o Without cap : lead in the width. Specify the necessity of connection to the earth or not. o Under a small cap such as CMBPE : lead+ earth leads, under galvanized steel lead. Orientation of the connection box : axial, 30°. See definition of connection, p.5. Special manufacturing : o Accessories and options o Possibility of manufacturing in stainless steel. o Define a special strip heaters, see p.8. Voltage: 500 Vac max., single phase. Length : Encapsulated mica strip heaters : 80 to 450 mm. Sealed heaters : 450 to 1180 mm. Length > 1200 mm, according to a faisabilty study Material : brass in standard model. o Encapsulated mica strip heaters: Encapsulated with fold over and brased extremities o Sealed heaters : Sheat in brased or welded brass according to the model. Technology sealed to plastic. Manufacturing according to the standard EN 60335-1 - Wattage tolerance : +5%-10% - Leakage current < 0.75 mA/kW NON METAL SHEATH MICA STRIP HEATERS • Tailor made strip heaters. Max. watt density over the surface of the heater : 4 W/cm². Max. working temperature on the strip heater : 340°C. These parameters depend on the using recommandation and the connection type. Width : 20 to 600 mm, according to the feasablility study. Length : 50 to 1100 mm (Min Lg according to the connection) Thickness : 1.2mm, without connection. Electrical insulation by mica. The heating elements have not mechanical protection. We have to protect them notably against mechanical shocks. Connection : o Leads : - nickel core, insulated by flexible silicone rubber. (Max working temperature : 180°C) - nickel, insulated with fiberglass silk silicone (Max. working temperature : 340°C) o Nickel steel, ring faston terminal cable lug. Disposition of the connection : - In the width in standard or on the top, according to a feasability study. - Disposition : on the same side, on both sides. See definition of the connections,p.4. Voltage :230V for standard. Voltage : max.500 Vac. ... Single phase or three-phases (from width 90mm) 6 leads connection : three-phases, commutable 230V/400V. Number of connection : according to the intensity. Nota : heating elements delivered without earth. • Manufacturing according to the standard EN 60335-1 - Wattage tolerance : +5%-10% - Leakage current < 0.75 mA/kW Special manufacturings : o Various shapes : manufacturing possible in circular shape (connection leads) o UL approved for the USA and CSA approved for the Canada.
