Oil immersion heaters, As oil heating usually to be done at low watts surface area density. As casted finns provides high surface area to be in contact with oil and does not burn oil but heats up oil faster in small area,resulting in compact heating system.

Oil heater, Finnes are of special aluminum material giving best heat transfer. Using our special designed immersion heaters you can accommodate three times wattage than standard heaters benefiting in reducing size of oil heating system to 13. So it lowers cost of fabrication as size of tank reduces,with efficient heat transfer in turn saves electric power.

flat mica heaters are constructed with a resistance wire or tape wound on a mica sheet insulated on both faces by mica sheets. These very thin heaters offer a very fast response and can be designed to any required size. They can also be protected by aluminium or nickel plated sheet. flat ceramic heaters are constructed with a resistance wire wound on ceramic insulators and protected by stainless steel sheath. These elements are used for heating moulds, tools or press platens up to 650 degrees c.   application            alternative fuels            power generation            food equipment            bio pharmaceutical            marine applications            medical equipment            petrochemical processing            transportation            wastewater treatment

Navbharat Electrical Industries has developed high wattage electrical heaters for on line oil heating systems and heat packs. Heaters is designed to give high wattage but at low watts surface area density. As oil heating usually to be done at low watts surface area density. As casted finns provides high surface area to be in contact with oil and does not burn oil but heats up oil faster in small area,resulting in compact heating system. Finnes are of special aluminum material giving best heat transfer. Using our special designed immersion heaters you can accommodate three times wattage than standard heaters benefiting in reducing size of oil heating system to 1/3. So it lowers cost of fabrication as size of tank reduces,with efficient heat transfer in turn saves electric power.

design the electric resistance element is a spiraled nickel-chromium (80:20) wire mounted in articulating specially designed ceramic supports forming a flexible mat. This mat is mounted in a stainless steel shell with 3 mm thick heat insulation. The webs of this channel shell are fluted in a manner that allows it and the heating mat to flex readily to any radius. The band is fastened by lock-up flanges integral with the shell.   features the ceramic insulated band heater is particularly recommended where temperature in excess of 800° f in plastic machine assemblies, such as heater cylinders, is required. Watt density in the order of 7.2 watts per square c m is considered as maximum when used for this purpose. A more conventional rating is 6.4 watts per square c m, but any lower density can be furnished to meet the requirements of the application.   specification these heaters are manufactured to specification only. Diameters may be specified from 25.4 mm id and larger in any fractional increments -- widths from 37 mm up in 12 mm increments. Since several sizes of ceramic supports are used to accommodate varying heat loads, thickness varies from 11 to 16 mm. Holes for temperature control instruments (or for clearance) can be provided in the body of the heater or provision made at split line connection may be screw type terminals, with or without terminal covers, flexible lead wires with or without armor, or twist lock plug. Unless otherwise specified, screw type terminals are furnished. Any conventional line voltage may be specified, single or multiple circuits.   the hot facts            maximum production            higher operating temperatures            completely flexible -- quickly and easily installed -- no precison adjustments            unaffected by expansion and contraction of part being heated            fast heat -- up            long life   special design the ceramic insulated heater can also be supplied in various designs (rectangular etc) and variations to the 360° cylindrical band. while ordering ceramic insulated band heaters.. please specify the following:    inside diameter of heater band (or the outside diameter of the part around which the heater is to fit)    width (frequently referred to as "length")    type of line connection (ie screw terminals, flexible leads etc)   opening beween lock-up flanges (standard gap is approximately 10 mm). A larger opening might be      required if temperature control instruments etc are to be inserted at this point.   if any clearance holes or cut-outs are required in the body of the heater, the size and location      (preferably by sketch)    watts    volts   application            heat sealers, hot plates, laminators            hot meltadhesive tanks   usage            ceramic band heaters are used in melting processes
