A Sisteven heat recovery unit with transparent side panels reveals its diagonal plate heat exchanger and fans under purple, orange and yellow lighting. A second Sisteven unit to the right has an open section labelled "ELECTROSTATIC FILTER", and a ceiling-mounted unit hangs near a small meeting table. The adjoining Sodeca stand displays the line "Ventilation solutions".
