Server Rack Airflow Management from HotLok®

Server rack airflow management saves energy by reducing hot spots and allowing for lower cooling unit setpoints. HotLok airflow products have been specifically engineered to avoid high temperature intake air. This is done by controlling the hot exhaust air and preventing it from reaching the front of IT cabinets, creating a 99.97% effective seal on your cabinets.

HotLok rack airflow products let you optimize cooling and increase equipment reliability by controlling bypass airflow, reducing hotspots, and allowing lower temperature air to be delivered to the intake side of server cabinets. HotLok products are snap-on in seconds and start saving money!
