Thesslagreen showed its "Centrala wentylacyjna AirPack4" with the front removed, exposing the green hexagonal counterflow heat exchanger and the moulded insulation housing. The wall above reads "Wentylacja domu z oczyszczaniem i nawilżaniem powietrza", and visitors study brochures next to the unit.
