Prevent Heater Damage and Premature Heater Failure he four most common factors that contribute to premature heater failure are: 1. Contamination 2. Corrosion 3. Over temperature 4. Lead wire failure Protect Your Heater From Contaminants Contamination occurs when foreign materials enter a heater’s internal area resulting in a breakdown of the element or insulation materials. Contaminants are usually organic and cause either a gross electrical short to ground or an accelerated deterioration of the heater’s internal elements and/or power leads. Heaters that are prone to large temperature...

Prevent Heater Over Temperature Watlow designers optimize the internal construction of your FIREROD heater based on the wattage and operating temperature that you specify. However, various conditions can cause the heater to reach over temperature. The incidence of heater over temperature is minimized by reducing mineral deposit buildup, correctly sizing a hole to fit the heater and choosing the optimum heater insertion length and sensor location. Length of no heat that extends beyond the heated part 0.25 in. FIREROD Prevent Buildup In Immersion Applications Table 1 Seal Type A heater that...

Graph C: How Hole Fit and Watt Density Can Affect Internal Heater Temperature Heater Operating Temperature [in block heated to 1000°F (537°C)] A loose fit causes cartridge heaters to operate at temperatures that are much higher than the part being heated. This is even more dramatic at higher watt densities. Using a tighter hole fit and lowering the watt density will keep the heater’s internal temperature low, prolonging its life significantly. Hole Fit Cartridge Heater Size The Hole Correctly To Fit Your Heater Choose The Correct Sensor Location Over temperature failure frequently occurs...

Graph D: Recommended Maximum Hole Fit For Heating Metals 0.100 0.090 0.080 0.070 For stainless steel, enter the graph with a fit 0.0015 inches larger than the actual heater size. For aluminum and brass, enter the graph with a temperature 100°F (37°C) above actual temperature. Fit equals the maximum inside diameter of the hole minus the minimum outside diameter of the FIREROD heater. The graph helps to determine the maximum allowable hole fit for an application. Note that both the heated part maximum temperature and the heater’s surface watt density affect the recommended hole fit. Protect...

FIREROD Cartridge Heater Industry Solutions Semiconductor A large semiconductor equipment manufacturer of back-end inspection and packaging processes uses FIREROD cartridge heaters. Heaters need to be designed with multiple heated zones in a short heater length to ensure consistent sealing of finished chip packages. The FIREROD heater’s increased uniform thermal profile along its length substantially improves the yield of the process, extends the life of the heater and reduces downtime and maintenance issues. Medical Equipment A heater used on equipment that interfaces with a patient during...
