Side view of the Pro-Vent stand, where a unit marked "Prototyp" carries the claim "Rekuperacja z pompą ciepła – Dostarcza ponad 80% energii grzewczej". A transparent case presents the Mistral City recuperator, panels describe reference projects in Polkowice and Bierawa, and visitors sit at a meeting table on the blue floor.
