Liquid Heating Applications
General Recommendations
GLO-QUARTZ® standard immersion heater ratings match the suggested watt densities for electroplating and immersion heater applications using bottom tank heaters, over-the-side heaters, screwplug and flange heaters.
Extended heater life will be obtained by using the lowest watt density practical for any given application.
