Prodmax, signed "Producent rekuperacji" on a grey textured wall, lines up white heat recovery units on stands at the front, including one labelled "VERO 250 PREMIUM". A column of blue and green flexible ducts marks one corner, while visitors meet at tables near shelves of ventilation fittings at this Warsaw show.
