DDM II Long-Reach Nozzle

A high-velocity air terminal device designed for projecting conditioned air over long distances in large spaces. Its spherical nozzle allows for manual or automatic adjustment of the airflow direction to target specific zones.

Product Description

Key Features & Benefits

Long-Distance Throw
Engineered for high-velocity air projection to deliver conditioned air across large halls and auditoriums.
Directional Air Targeting
Spherical nozzle can be adjusted to aim airflow precisely, allowing spot conditioning of specific areas.
Multiple Control Versions
Fixed (P), Manual (N), or Motorized (S) actuation for automated, BMS-integrated control (±25° adjustment).
Wide Temperature Range
For both heating (ΔT ≤ +25K) and cooling (ΔT ≤ -14K) applications with significant temperature differences.
For Large-Volume Spaces
Ideal for spaces where air needs to travel far from the discharge point to reach the occupied zone.

Installation & Control

Mounting Locations

Installed into walls or ceilings, typically on the side or end of rectangular or spiral (spiro) ducts.

Fixing Method

Fixed and manual versions have pre-drilled mounting holes. Motorized versions have an extended housing for the actuator.

Aiming & Adjustment

Manual (N): Adjust spherical nozzle on-site to desired angle in any direction.
Motorized (S): Set via actuator for single-axis movement.

Actuator Caution

Motorized actuators have colored end-stop marks. Warranty is void if these marks are damaged, indicating over-rotation.
