Induction diffuser DISA-H Description Induction diffusers combine the flow characteristics of air diffusers with the energetic advantages of load discharge via water-based heat exchangers, allowing them to remove high thermal loads from the room while keeping the hygienically required air exchange low. Its low installation depth and horizontal air flow makes it suitable in particular for installation in suspended entrance halls and in suspended ceiling panellings, such as in hotels, hospitals and offices. The primary air (1) supplied from the plenum box induces secondary air in the room...
