The Hotlok blanking panels achieve the following:

  • Reduce hotspots and bypass airflow by preventing equipment exhaust air or hot-aisle air from migrating to the conditioned air-intake stream at the front of the cabinet
  • Deliver lower temperature conditioned air to the upper one-third of the cabinet, typically the hottest area and most prone to equipment failure
  • Control airflow to save energy by adjusting cooling unit setpoints
