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
  • Identify temperatures within a particular range, accurate to within +/- 1° C:
    • Blue: Optimal Operating Range based on recommendations from ASHRAE
    • Yellow: Acceptable Operating Range based on equipment manufacturers’ recommendations for Class 1 IT equipment
    • Red: Outside acceptable operating range, indicates a definite hotspot or potential for condensation, either of which may result in equipment damage or failure
