Radial Displacement Nozzle

The PRICE DRNi-HC Series radial displacement outlet, manufactured by Krantz®, is intended for use in applications where it is not feasible to install the displacement outlet in the occupied zone. The DRNi-HC series was developed to ensure the best displacement air flow in the occupied zone for these cases. Equipped with a heating and cooling function the DRNi-HC is able to adjust the spread of discharged air thus removing pollutants from production sites and workplaces with minimum mixture of indoor air. These diffusers typically discharge downwards from a height of 16’ – 26’ (5m – 8m) above the occupied zone.
