Common applications are offices, schools, department stores and laboratories. The small nozzles distribute the air evenly uppwards. Short air throws are achieved through induction of room air in the large number of nozzles. NDC is suitable for cooling with max undertemperature of 6K. The length of each duct various with air flow, size etc. but can be up to 25m.
Max inlet velocity in the duct is 4 m/s.
