We are about to re-wrap our BCl3 line with heat tape and insulation and are in need of some advice. In the past we have used the rather expensive silicone constant wattage heaters with adjustable power control

https://www.mcmaster.com/heat-tape/constant-wattage-heaters-with-adjustable-temperature-control-for-pipes-and-tubes/</a> . The problem we have is that these do not seem to last very long before burning out, and as I mentioned are quite expensive. Does anyone
have a better solution? Longer lasting and cheaper? I should mention that we need only to keep the tubing at maybe 30C to prevent condensation of the BCl3 vapor.

I was looking at self-regulating heat tapes used to prevent pipes from freezing (an interesting technology in its own right) but am not sure they operate above room temperature given their intended application.
