The DRPBi-HC, manufactured by Krantz Komponenten®, is designed to generate constant
displacement airflow for applications with high discharge heights and pollutant
concentration, such as an aircraft paint booth. The DRPBi-HC is able to project large
volumes of air deep down into the room. In cooling mode, air is supplied from the
perforated face creating an umbrella shaped pattern into the room. In heating mode the
center nozzle is activated, entraining primary air from the perforated section, projecting
down into the occupied zone.
