Electric Heaters > This Application Guide is to assist youin understanding the principles of electric thermal systems and compo-nents as they apply to various heating tasks. Its purpose is to give you theory, general calculations and engineering data along with examplesfor solving heating problems. ThisApplication Guide is not a how-tomanual or a substitute for specific information related to complex and/or critical applications. Watlowengineers are available to provide you detailed information on engineeringapproaches not included in this guide.When designing any thermal system,caution must always be exercised to comply with safety requirements, localand/or national electrical codes,agency standards, considerations for useintoxic or explosive environmentsand sound engineering practices.Integrity and suitability of any thermal system design/specification is ultimately the responsibility of those selecting and approving system components.This Application Guide is organizedinto sections dealing with the basicfacets of an electric thermal system: the electric heaters, temperaturesensors andtemperature and powercontrollers. Information about wiringpractices along with reference dataand examples are also provided.As always, Watlow Electric Manufac-turing Company stands ready to provide you advice or engineeringexpertise to design and producecomponents to meet your electric heating requirements.
