HotLok Rack Airflow Management Kit Sealing Membrane 100-Foot Roll




HotLok sealing membrane is used to attach HotLok extrusions to the side rails. The sealing membrane is part of a server rack airflow management (RAM) system designed to greatly reduce bypass and re-circulated airflow within your data center cabinet. This sealing membrane works in conjunction with vertical extrusions mounted between the rails and the internal server cabinet wall. Sealing the vertical blanking panel also isolates exhausted airflow from the rear of the cabinet. This effective tool compliments sealing server cabinet space and increases usable cooling unit capacity, thereby maximizing cooling infrastructure efficiency.

This versatile product is composed of Flexible PVC with a matte black finish, comes in widths of 2.5/4.0/5.5 inches wide, and 100-foot length rolls. The vertical extrusions (blanking panels) can be easily cut and shortened, and sealed with this membrane, allowing on-site customization.
