Technical Data
   
   

Over the Side Heaters are used in applications where drilling a hole into the tank wall is not possible or desirable. The heater can be installed resting at the bottom of the tank or hanging from the lip. Over the side heaters are available in a variety of sizes, materials. and configurations The heating elements are offered in a number of materials suited to a variety of fluid heating applications. Terminal housings are available for indoor, outdoor (weather-proof NEMA 4) and explosive (NEMA 7) environments. Many options are available including thermostats, high limit and process thermocouples or RTD sensors. Since we are a made to order company, we can offer a large selection of sizes and configurations which are not listed below. Please contact us for assistance with your application.
