@Mr.Clean I appreciate you taking the time to lay all of this out. It’s obvious a lot of work went into documenting the videos, screenshots, and operator-side details. That type of firsthand record is a lot more valuable than any amount of marketing talk.
What stands out to me is how specific Zack’s public ProJak claims were:
- capable of going below -110C with just propane
- +50C to below -50C on demand within minutes
- and doing so while removing the need for costly ancillary heaters and chillers.
That paints a very clear picture of what buyers are being led to expect:
- extreme thermal performance
- minimal dependence on traditional heating/chilling equipment
- and a system that is largely self-operating
But the owner/operator material in this thread paints a much different real-world picture:
- substantial chillers still showing up in installs
- manual, valve-heavy operation
- even a “best case scenario” start still showing injection temps only around -10C, then quickly climbing positive, including +6C at injection just from circulating through an empty column
- the operator’s own summary was that the machine was “unable to keep up with the system itself” and “can’t get out of its own way”
That is a very different picture from what was marketed.
@Myrrdin I get not wanting threads like this to turn into a dogpile.
But when the public claims are this specific, comparing them against real-world operator results isn’t mob mentality it’s just basic due diligence. Extraordinary claims require extraordinary evidence.
If an owner bought into claims like these, structured a facility and business plan around them, and then ended up buried in troubleshooting, retrofit costs, and underperforming output, the frustration is easy to understand.
