NR series circular, constant volume terminals with system powered mechanical regulator are designed to keep a constant air flow, independent of the inlet static pressure without the use of a DDC CAV/VAV controller/actuator. These terminals save commissioning time on site and are suitable either for supply or return air in new or refurbishment projects.

Type NV rectangular pressure-independent VAV air volume control terminals are designed particularly for systems with high variations in heat load. The terminals induce room air and mix it with conditioned primary air, maintaining a nearly constant air volume to the room thus providing sufficient air movement necessary to maintain occupant comfort even in extreme load variations. This specific characteristic means that cold air ‘dumping’ will not occur and that extremely low primary air temperatures can be used, without producing excessive differences between the supply and the room air temperature. The primary air is controlled by the patented airflow sensor type Flo-Cross®.
