Bottom
Outlet Heater Application Basics
Bottom Outlet (also referred to as Urn Heaters and Steam
Table Heaters incorporating a Tubular Heaters construction.
Bottom Outlet Heaters are designed for installation through
the bottom of a tank for direct water immersion heating. The
assemblies are designed to fit into a 2-7/16 inch (61.9 mm)
diameter mounting hole.
Heater must be installed in system so that heater sheath
tube is covered by liquid at all times during operation. There are
several catalog models provided with a low-water cut-out that
shuts off power to the heater in event the heating element is
exposed to air.
Heating performance in tanks can be improved by agitation of
the liquid in the tank.
Sheath corrosion resistance and watt density compatibility
is extremely important in direct immersion heating applications.
The suggested sheath watt densities in the tables should be
considered maximums unless testing in the particular application
shows that higher densities can be used.
Please refer to general application guidelines, recommended
watt densities, sheath temperature limitations, corrosion guide,
and other engineering data to assist you with product selection.
Please do not hesitate to contact us for application or
product assistance. |
