Electric Resistance Heater Diagram. The material to be heated may be considered imperfect dielectric of a condenser and may be therefore represented as a capacitance placed in parallel with a resistance as shown in fig. Figure 2 typical storage heater circuit diagram figure 3 storage heater with fan heater built in source creda 4 of 6 3 common problems there are three sets of common problems with storage heaters.
Electrical resistance heating elements. Se lect contactors based on resistive load ratings. The design of electrical resistance trace heating systems shall be overseen by persons knowledgeable of trace heating following the design methodology for explosive atmospheres as specified by thermon engineering or computrace electric heat tracing design software.
Equipped with a thermal switch which opens at 90 c and re sets itself after cooling down.
6 rits spring 2007. Heating elements with low surface temperature are individually wired to the outer terminal box and coils can be wired in several groups. Ambient temperatures must be considered when selecting wiring materials for electric heater circuits. Forms the secondary circuit and is magnetically coupled to the primary by an iron core.
