HotLok 19 Inch Rack Blanking Panels

1U & 2U HotLok 19 Inch Rack Blanking Panels

HotLok 19 Inch Rack Blanking Panels, from Upsite Technologies, are 1U or 2U in size and are designed to seal unused spaces within 19″ racks.

Sealing unused rack space with 19 inch blanking panels plays an important part of an effective airflow management policy. By blanking out unused rack space with 19 inch rack blanking panels it prevents hot server exhaust air from circulating back to the front of the rack where it can cause hot spots and interfere with the cold air cooling the IT equipment. HotLok rack blanking panels have finger grips for easy installation and removal and their cantilevered vanes seal against installed equipment or other HotLok blanking panels. They are also available with a built in temperature strip which provides a visual guidance on the temperature at the rack, this temperature strip is also available separately. Other products within the HotLok range includes the HotLok Rack Airflow Management Kit that seals the gaps between the rack sides and rails, and the top and bottom to the frame, and the HotLok Round rack grommet for sealing cable entries on racks. Also within the HotLok product line is SwitchFix, a range of products designed to help cool network switches.

Using 19 inch rack 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.
