Rack Airflow Management from HotLok®

Rack airflow management could save energy by allowing lower cooling unit setpoints.

HotLok airflow products have been specifically engineered to avoid high temperature intake air. This is done by controlling the ability of hot exhaust air to reach the front of IT 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.
