Resumen del manual
Each unit consists of a ceramic fiber heater mounted in a 2.5 inch (64 mm) deep sheet metal case that provides thermal insulation. The case includes post terminals for electrical connections and provides a mounting system that can be used with virtually any flat ceramic fiber unit, whether it is a stock, standard or a custom size. Since any of the flat unit heating element configurations can be used—exposed sinuated, embedded coil or foil elements— watt density and temperature capabilities can be tailored to meet specific radiant applications. Applications • Conveyor furnaces • High temperature vessel heating • Tempering and annealing processes for glass, wire, ceramics and metals • Coating, curing and drying of inks, paints, plastics and films Heating Element (Sinuated Wire Shown) 1/2 in. (13 mm) Ceramic Fiber Insulation Thermocouple Mounting Clamp 2 in. (50 mm) Thick Ceramic Fiber Heater Mounting Legs Features and Benefits Lightweight, low mass design • Allows fast response to controls High efficiency • Results from high degree of self insulation with 2.5 inch (64 mm) thick mounting case Adaptable • With any stock or standard sized flat ceramic fiber unit Thermocouple mounting clamp • Makes process system control easier Aluminized steel case • Handles temperatures up to 595OC (1100OF) Special hot face heating patterns • Designed specifically for applications using an etched foil RAYMAX 1220 STL-1220/2030-0805 12001 Lackland Road St. Louis, Missouri 63146 USA Phone: +1 (314) 878-4600 FAX: +1 (314) 878-6814 Internet: e-mail: info@watlow.com © 2005 Watlow Electric Manufacturing Company Printed in the USA on Recycled Paper, 15% Postconsumer Waste Applications and Technical Data Specifications Weight: Under 6.5 lbs/ft2 (31.75 kg/m2) Voltage and Wattage: Ratings are based on the ceramic fiber heater module, which is mounted in the case. Up to 600VA(ac) is possible. Terminals: Terminals are 1.4-20 threaded studs. Two terminals plus ground for single-phase, and three terminals plus ground for three-phase, are standard. They will be located on the center line of the length unless otherwise specified. Terminals can be located anywhere along lines A and B (see illustration), but not closer than two inches (51 mm) to the case ends. Mounting Legs • One inch (25 mm) standard • Three inches (76 mm) optional from stock. For made-to-order units, mounting legs can be supplied in any incremental length L from 1.2 inch (13 mm) to three inches (76 mm). No slots are provided in legs less than one inch long. Application Hints: A thermocouple mounting clamp will be provided on one end of the case, with holes on both ends for alternate locations. The standard clamp can be used with 1.8-inch (3.2 mm) O.D. sheath thermocouples. The standard clamp is 3.16 inch (4.8 mm) high, but can be removed for flush mounting*. The maximum recommended surface temperature of the heater is based on the rating of the ceramic fiber heater module. This can vary from 1095°C (2000°F) at lower watt densities, to higher watt densities at reduced surface temperatures. Note that maximum wattages cannot be achie...
