I run an inline heater from LightObject.
Do you mind posting a link for that inline heater?
Is it something like this?
Yep that’s it.
I have it turn on at 15C off at 17C. Chiller kicks in around 19C

While I cannot prove at this point in time this method works ( repair not tested yet) I can explain what I did to repair one that looks just yours (or did).
Have a friend that had the 60w tube in his laser freeze and took the end off just like yours. He was about to through it out but ask if I wanted it and i said yes as I believed it was repairable.
I had some glue on hand to repair windshield cracks, so I glued the glass “lid” back on. Note to “cure” the glue it must be exposed to sunlight for a few hours so for two afternoons in a row it sat out in the sun.
After that two coatings of JB weld, the glass formula, completed the repair.
Again the tube has not been tested at this time as I didn’t wont to mess with the tubing in my 60w machine and do not have a spare pump.
Did not see any other signs of damage to the tube and very confident the “patch” will work.
Will post pic’s when the phone and computer work together and download the pic’s into the computer.

I’ve read a number of ‘posts’ about frozen tube that have cracked…
I have found none that have had success doing this as they all ‘leaked’ the gas mixture out of the system…
I’d be very interested when you test it to see if it worked with your patch…
Can you see ‘pink’ inside, like the gas is still ok?
Good luck
it looks like it’s just the cap at the end of the tube with the reflective mirror(opposite the output) so I might be a matter of sealing up the end so water can flow through and help keep the metal mirror cool. @B25P51 looks to have done a good job of describing a technique to seal it but instead of rolling it into the weak Winter sun maybe a good UV light could cure the glue.
Not much to lose but a little time and a few bills for the glue.
hi there rich did you manage to get your new tube sorted ??? to be honest it happened to me and i bought a SPT tr90 from cloudray which was ordered and delivered in 6 or 7 days i had a ERF 80w and replaced it with the 90w so had to get a new power supply as well… the tube was well packaged and also in a wooden box… what was the jacket you made for you laser tube as i was thinking of using antifreeze but so much confussion i did not want to risk it

Does that have the builtin led?
I think when I replace mine, I’ll do similar, but don’t think I’ll go with much of anything above what I have, power wise.
yes it does have a red dot built on the end just need to connect it to a 5v power
I took mine off within a month or two of getting the machine, so I’ve only used the visible tracing on my led types…
Hate to cough up $300+ for a tube, but it’d be nice to have it available if I wanted to use it. Of course they are high quality tubes…
With the original led, I had to ‘re-aligned’ it so much I found it wasn’t worth it and a jig to hold the item works even better…
A jig is comparable to the camera option…
i had to get a new tube so just thought i would go with one that had the red dot built in rather than the one on the laser head not cheap shipping to the uk that’s for sure
hi, what about this ?
If this heats the coolant container, the tube itself can still freeze - unless you keep it’s circulating pump running all the time.
I don’t know how cold it is there, but I ran one of the propylene glycol they use with milk cows. I diluted it as thin as I could for our worst weather… It is thick and slows down the flow, but doesn’t hurt the dielectric constant of the coolant.
The last batch I got off Amazon was OMTech coolant.
Good luck
Ok the tank heater is a Big fat fail (avoid)
I opted for a ice maker instead works great
not sure if it was mentioned but when you use the tank heater you also must have your tube circulation pump running 7/24 and it would be best to at least insulate your tank so the heat doesn’t leave faster than it can be supplied.
