* 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.
How to Use: Note:
1) Check to be sure you are using the correct chart. The watt-density selected will maintain
2) Choose your operating voltage. the temperature indicated at a minimum.
3) Choose the minimum process temperature you Depending upon actual ambient fluctuations,
want to maintain. Note: If temperature is not shown, process tubes size and number of tubes, the
pick the next higher option. maintenance temperature could be higher.
4) Follow chart across to the ambient Condition that
best match your area.
5) Use the watt-density shown for your part number
derivation.
