55 Gallon Drum Heater Classified Area – Self Regulating Design

    New application or replacing a previous heating solution?*

    Can we define the shape & size? If cylindrical what is the OD of the cylinder and length confirmed?

    Do you have any photos of the vessel to be heated?

    Are there any features that need to be accommodated?

    Material the vessel/item to be heated made of?

    Supply voltage desired?

    Amperage available?

    Starting temperature?

    Target temperature?

    Temperature accuracy needed? +/- 5F or more precise <2f?

    Do you require a temperature sensor in the heater? This sensor can work with an existing Temperature Controller if desired

    Do you desire we quote you a Digital Temperature Controller? We can provide both On/Off or PID Logic Enabled Temperature Controllers

    Adhere the heater to the cylinder or do you need to remove it?

    Is the area Classified/Explosion Proof?

    It is the heating application outside? If so, will the heater going to exposed to the elements?

    Quantity needed?

    Any other important details or description of the project?
