Thanks for the correction, it does not have a dedicated chamber heater. But I don't think simplifying it to "chamber exhaust" is correct.
It sounds like the real claim is the device can actively keep the chamber at 55C. Other than semantics, I don't understand how this is different from having a dedicated chamber heater. I can close my X1C, but it won't maintain any stable temperature. The bed and nozzle are heating the chamber. This is all assuming the time to get to 55C is reasonable, and that 55C is enough. I personally have a need for 55C chamber often, but never 100C (X1E can only get to 60C).
Again, feel free to correct if I'm wrong, but directly from Prusa: "The automatic ventilation system and active temperature control"
The way they describe the active chamber management in their blog post is basically to say “the enclosure allows it to reach temps as high as 55C, but you can keep it enclosed and drop the temperature so you can print PLA and PETG”. There might be some insulation perhaps, but getting to 55C is not particularly hard on almost any printer. Uninsulated printers with enclosures that are reasonably tight will hit 55C no problem. Add some insulation and you can hit 70C pretty reasonably all without any chamber heating.
