* The above heater cable selection is based upon our standard insulation package, other insulation packages are available to maintain higher
temperatures.
** The maintenance temperature could actually be higher depending upon the size and number of tubes required, it is recommended that
for precise temperature control that a thermal sensor be used. Contact the factory for more exact product thermal property based upon your
application conditions.
