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...
