Here is the email from the manufacture. These can run at 250C continuously. The main point is that we have a quote for units which can be purchased for testing at 250C to confirm if this will work.</div>

<div class="PlainText">Hi Marc<br>
<br>
I'm worried about 250C max. All the time this heater<br>
will work the maximum mode.<br>
When testing the prototype in the front flange SM, we reached 250C, which<br>
is half the maximum operating temperature of the heater that I used.<br>
How many days continuously can this heater operate at maximum?<br>
<br>
Thank you,<br>
Albert<br>
