Enter the chart with eitherknown variable, part fit in hole dimension or W/in2. Thenfind the application temperature by reading up or over on the chart. If the fit of the heater in the hole dimension is not known,it is easily determined. Subtract the minimum diameter of the FIREROD (nominal diameter minus tolerance) fromthe maximum hole diameter. For example, take a hole diameter of 0.500 (13 mm) minus a heater diameter of 0.496 in. (12.6 mm) 0.002 in. (0.05 mm). The hole fitwould be 0.006 in. (0.15 mm). For FIREROD heaters in square holes or grooves, contact your Watlow representative for the fit in hole dimension.The following four charts detail maximum allowable wattdensities for applications involving metal, steam, air or gasheating. Please review these respective charts andapplicable data to determine the correct watt density foryour application. Fit in hole = maximum hole I.D. minusminimum heater O.D.Correction FactorsAlso note, these graphs depict FIRERODs used in steelparts. Therefore, for either stainless steel, aluminum orbrass, refer to applicable correction factors:1. For stainless steel, enter the graph with a fit 0.0015 in. (0.04 mm) larger than actual.2. For aluminum and brass, enter the graph with a temperature 100F (38C) above actual temperature.13 WATLOWCartridge/Insertion HeatersFIREROD Cartridge HeatersMaximum Allowable Watt Density (Continued)10 20 30 40 50 60Firerod Sheath TemperatureF Watt DensityW/in2200015001000500Not Pre-oxidizedPre-oxidized160014001200100080060040020010 20 30 40 50 60Ambient TemperatureF Watt DensityW/in2Watt Density vs. Ambient Air TemperatureThe Watt Density vs Ambient Air Temperature graphshows the maximum allowable watt density when oneFIREROD is operated in air or similar gas.For FIRERODs grouped in a single row, with no less thanone diameter between elements, multiply value fromgraph by 0.95.

The HT FIREROD utilizes the same industry leading design principals used on all of WatlowsFIREROD products. Taking the cartridge heater one stepfurther enables the HT FIREROD to withstand applicationtemperatures up to 400F (204C) higher than standardcartridge heaters.There are certain differences in the HT FIREROD designwhich are important in high temperature applications: HT FIRERODS are specially constructed with an end seal that is virtually airtight to reduce the effects of resistance wire oxidation The high temperature sheath is treated to improve its emissivity for better heat transferPerformance Capabilities Platen temperatures to 1800F (980C) Maximum watt density to 100 W/in2(15.5 W/cm2) Maximum voltage 277VAC to ground Length tolerance: +0, -4 percent standard diameters;+0, -8 percent for special diameterFeatures and BenefitsHigh temperature seal Reduces exposure to the atmosphere which minimizes oxidation of the winding wires, resulting in longer life of the elementNote: First 2 in.
