Properly Positioned

Tolerance comes into play when a flange or mounting bracket is added to a Watt-Flex® cartridge heater. Length tolerance is +/- 3% up to 20" length and +/- 2% over 20". So if your heater is 38" long, the tolerance is +/- ¾".

Positioning a flange or mounting bracket on a Dalton Electric heater requires consideration of the length and corresponding heated section. The flange can be affixed to the heater with a measurement from the terminal end ("A" dimension) or from the tip end to the flange ("B" dimension). The "B" dimension controls the insertion distance and consideration must be applied to ensure that the cold section of the heater at the terminal end is long enough to have the heated section beyond the flange if the heater is at the long side of its tolerance.

If the flange is specified using the "A" dimension, the insertion will vary with the length tolerance of the heater. The critical consideration becomes making sure that the heated section is still in the bore at the tip end if the heater is at the longest side of its length tolerance. We will always get back with you if we sense any reason for concern with your design.
