PlenaFill® blanking panels are supplied in 27U sheets and can be cut to any required size, avoiding the need to store several sizes of traditional blanking panel. PlenaFill® blanking panels are a proven solution to eliminate hot spots and reduce overal cabinet temperatures. Air-intake temperature is known to be a significant factor in the reliability of IT equipment, with raised intake temperatures leading to equipment failure and expensive downtime. A major cause of raised air-intake temperatures is hot exhaust air recirculating through unsealed, open rack space. Using blanking panels helps eliminate this issue. However, standard blanking panels have a horizontal gap between them that still allows hot exhaust air to leak into the front of the rack. PlenaFill® blanking panels are fixed in a sheet and eliminate this gap. Also by preventing the recirculation of hot exhaust air you’ll reduce bypass airflow and save on energy costs.
