HTC airstop protecting shockfroster doors

Is this a kind of magic or another good example of the typical efficiency of Masterveil’s invisible doors; Thanks to a precise airstream to cover the total door of a shockfroster, the cold is staying there were it belongs.
Worker in the frontroom are finally receiving the comfort that they aimed for.

The measuring routine shows very clear what happens with a running system or what happens when you stop the Airstop. Avoiding energylosses towards the frontroom, considering the energyprices today , is an extra bonus in this job.
