Hello Bholowka, the ventilation openings are at the front (propeller) and in the front area on the left and right side. All connections are at the front. So theoretically it should be possible to operate the box upright. However, the lid cannot be locked, it could swing open and would have to be secured somehow.

Unfortunately, I can't say what upright operation means for the built-in technology and longevity. We only operate it horizontally.

But the chest is great and has a strong cooling capacity. We would buy it again at any time.

Best regards
