The Innovation Company LTG Aktiengesellschaft Technical brochure Induction units HFFsuite for hotel bedrooms, ceiling installation View of unit With the 2-pipe unit it is possible to have cooling only, or cooling/reheating with a change-over circuit. The supply air is diffused into the room via permanently pre-adjusted baffle plates as a ceiling (Coanda)jet. The active induction check (optional) allows the unit to be "switched off". Only the centrally set primary air flow rate then provides basic ventilation for the necessary air change. Advantages  Low primary pressures - Low-noise operation...
