Manage Airflow and Reduce Costs

Drop Box Diffusers

Warehouse and distribution facilities present unique challenges, including high ceilings with large open spaces and significant energy costs related to maintaining the building.

Effectively managing airflow impacts utility costs and United Enertech's Drop Box Diffuser/Plenums provide a single point air distribution system with the added benefit of allowing directional airflow. Our diffusers help provide even and efficient air distribution, which contributes to having more consistent temperatures in large spaces such as warehouses and distribution centers.
