More About This Product

HotLok white blanking panels are designed to not only seal unused rack space, but there light colour helps reflect light into the aisle.

HotLok White Blanking Panels

HotLok white blanking panels are designed to effectively seal openings in IT equipment racks and control airflow for optimised cooling effectiveness.  HotLok blanking panels reduce hotspots and bypass airflow (any air which fails to pass through IT equipment) by preventing equipment exhaust air or hot aisle air from migrating to the conditioned air intake stream at the front of the rack.  HotLok blanking panels are available in 1U or 2U configurations and are now available in a more reflective white version.

The HotLok white blanking panels are ideal to co-ordinate with white or other light coloured racks for improved aesthetics.  In addition, they are engineered to offer light reflectance properties for energy savings by increasing the reflectivity in the server rack, and so reducing the amount of lighting required.
