Have used Pearl several times lately and these were cutting jobs with 1/8 inch and 1/4 inch plywood. The chiller has been around 20 at the start of the job and will rise to about 48 degrees. These jobs are not long jobs, lasting less than 30 minutes. Temperature rise has occurred on much shorter jobs also. I have now started to watch the chiller temperature but I have never had to do this before.

Thank you for posting. @jamesfreeman and @dannym chased down this problem on Tarkin. The chiller might be low on freon.

Thanks for the heads-up
Chiller problem. Will diagnose tonight
48C is way too high, that’s past the point where it can cause damage. Please red tag immediately

Pearl’s chiller has been repaired. Decent testing done on it tonight, but couldnt verify 45 minutes worth of it. Red tag has been removed, happy cutting!!!

Juiced it up with freon.

Apparently low on refrigerant. It just uses R134a so easy to refill.
There was no refrigerant capacity listed anywhere, so James just eyeballed it. It may not be the exact fill, but we did run it at 100% power and the chiller will keep up.
Basically, if the chiller can’t keep up, you’ll see that in a few minutes, longer testing isn’t necessary. If it can keep up, it should be able to do so indefinitely. But it make take a minute or two for the compressor to restart, creating a short window where temp will rise.
