A closer view along the Defro counter shows the white "DEFRO" letters on dark grey panels and an opened recovery unit with a hexagonal teal heat exchanger. Black insulated ducts curve between the units, a black "DEFRO air" panel sits at the front and the "HYBRYDOWE SYSTEMY GRZEWCZE" wall rises behind.
