Caldo builds its stand from dark grey open frames and white panels printed with line icons of heating and ventilation devices. A black heat recovery ventilation unit sits on a plinth with red underlighting below a screen showing "www.caldo.pl", while a map of Poland marks distributor locations and a planted wall fills one corner.
