These units provide a low watt density over a large surface area and are used to heat sensitive fluids. Advantages include the ability to change the heater without draining the tank and to provide up to a Schedule 80 pipe wall in mildly corrosive fluids.
    Heater pipes can be customer supplied or Built in to the Heater. Pipes can be welded into the tank wall or can be attached with an ANSI flange. We can also provide a weather-resistant terminal box with NPT threads attached to the end of the heater pipe. We provide complete Set up Instructions and Controls for monitoring and controlling tank temperature.
    Some Standard Sizes are listed below but we manufacture in various watt densities and lengths.
