the correct heater sheath material is necessary for electric immersion
heater longevity. GLO-QUARTZ®
Inc stocks standard sheath materials such as: 304 & 316 stainless
steel, Incoloy® 800 & 840, Copper, Titanium, Quartz and
electric immersion heater watt density is very critical when designing
a heater to last. i.e. Flanged heaters, screwplug immersion heaters
and circulation heaters should never be rated over 23 watts/sq.in.
(sometimes less based on the application) for any oil heating
application. Higher watt densities of your electric immersion
heater cause more build-up and stress which in turn shortens its
your immersed heating elements clean and free of debris and scale
will lengthen the life of your heater and improve efficiency.
Know your voltage. If the voltage is under specified, it can dramatically
affect the output of your: duct heater, circulation heater, screwplug
heater, tank heater, quartz infrared heater or quartz immersion
heater. Applying 208 volts to a 240 volt electric heater can reduce
your output wattage by 25%.
Take advantage of regular maintenance. Ensuring all electrical
connections are secure will prevent arcing and keep the wire terminals
