Impulse diffusers ISH Functional description Impulse diffusers discharge the air from air conditioning systems with a high momentum such that large throw distances are achieved. This allows for the ventilation of large areas. Type ISH impulse diffusers are used primarily for industrial zones without air polluting work processes. They are installed above the occupied zone. An adjustable air control disc allows for adapting the air discharge direction to heating or cooling mode. The supply air to room air temperature difference may range from –8 to +12 K. Cooling mode In...
