HotLok blanking panels are 1U or 2U snap-in blanking panels from Upsite Technologies.

HotLok blanking panels provide an effective seal in unused rack space that is 29% better than that of their nearest competitor. The state-of-the-art design of these blanking panels controls airflow for optimised cooling effectiveness. HotLok blanking panels are available in black, white or RAL7035 with some options also incorporating the Upsite Temperature Strip. HotLok also provide other rack based airflow management solutions that seal the gaps between the rack sides and the rails, seal round cable entries where cables enter or inter-connect between racks and solutions for cooling network switches placed in the back of cabinets.

Using blanking panels follows the 4R’s of airflow management, which defines how managing airflow at raised floor, rack, row and room levels, will enable optimisation of cooling systems
