The Innovation Company LTG Aktiengesellschaft Floor-mounted air diffusers type LDU-W and LDU-W/H View of unit Functionality The high-induction linear diffuser splits the supply air in diverging individual jets in a localized manner in parallel to the facade. Air speed and temperature differential are reduced rapidly. In the cooling mode, the air jets’ limited divergence creates a mixed air stream close to the facade or wall, forming a low level displacement flow in the occupied zone. This flow replaces air that "plumes" to high level from heat sources and occupants. Application Ventilation, heating...
