Electrical heater cable
ARI heater cable (AerOrod) is used to make heater assemblies for a variety of furnace and tracing applications. Standard cable is manufactured with sheath material Inconel 600 and Stainless Steel. ARI maintains a large inventory of finshed cable with specific resistance values (ohm/meter) to suit most applications. Custom heater cables with special materials and resistance requirements can also be produced.
All AerOrod heaters are manufactured with high-purity MgO insulation in a multiple reduction process which ensures uniform cross-sections and minimum wire-to-sheath spacing for maximum efficiency in heat transfer.
AeroRod electric Heaters are offered in a wide assortment of sizes, styles, and terminations. Amongst the list of benefits are:
- Flexibility - The element can be readily bent by hand or production machinery to any desired configuration and it can retain that configuration after repetitive heating and cooling cycles. This feature permits placing the heater where the heat is required and thus eliminates hot spots.
- High Watt Density - By choice of materials it is possible to obtain 150 watts per square inch of surface area without loss of other performance characteristics.
- Fast Time Response - By elimination of unnecessary volume, the weight and therefore heating time is greatly reduced.
- Corrosion Resistance - By using an Inconel 600* sheath, the heater can be immersed in many corrosive fluids without deterioration.
- Long Life - By new and patented methods of lead wire attachment, we eliminated the source of 70% of electric heater failures. We've used these types of heaters in aircraft applications and warranted 8000 hours of flight time (not energized time) which means that the total "on" time would exceed 20,000 hours. Industrial applications probably do not have as long a useful life since the enviroment is varied and often more severe.
- Nuclear Application - By proper choice of materials, these heaters can with stand long term exposures in the core of a power nuclear reactor with negligible deterioration.
- Efficiency - AerOrod® Heaters and Mineral Insulated Heater Cable are manufactured with highly compacted, high purity MgO insulation in a multiple reduction process that yields a uniform cross-section and minimum wire to sheath spacing for efficient heat transfer. This material can be easily formed to meet demanding specifications (minimum bend radius = 2X sheath diameter). The heater cable can be brazed or welded to give maximum power levels in difficult situations.
BXX style heaters have an internal splice from high resistance heaters wires to low resistance Nickel wires, to created an unheated-to-heated resistance of ration of approximately 10:1.
Apart from the above mentioned heater cable and heater assemblies Kamet is able to offer mineral insulated heating cable as well as complete factory terminated units
(heating cable with cold-tails) commonly used in the Heat-Tracing business.
These cables Kamet is able to supply in the below sheath materials:
- Stainless steel
- Alloy 825
- Inconel 600
Together with the current resistance values and the in this industry well known outside diameters.
