FAQ


Q:    
What watt density should I use?

A:    A lower watt density is best to maximize the heater's performance and
        lifespan, below is a table of materials and their watt density limits.

 Material:

Watt Density (W/in²): 

 Crankcase Oil SAE 90

 10 W/in² or less

 Machine Oil SAE 30

 15 W/in² or less

        Mineral Oil        

 15 W/in² or less

     Hydraulic Oils    

 15 - 22 W/in² or less

 Water

 22 W/in² or less


Q:    When would I want to use an explosion proof enclosure?

A:    The explosion proof encasement is necessary for hazardous locations with flammable materials.



Q:    At what temperature will the oil be maintained?

A:    The average temperature is 75º F but varies depending on the environmental temperature and the wattage output of the heater.



Q:    How do I size a heater for my tank?

A
