SJ Cold Aisle Containment

Dealing with data center temperature problems can be quite challenging when there is zero downtime windows. SJ Cold Aisle Containment is specially designed for today’s data center cooling systems. It’s unique airflow management strategy can produce significant and measureable economic benefits. 

SJ Cold Aisle Containment is designed to allow cool air to raise from the plenum under the raised floor, through perforated floor tiles. In the cold aisle, the server or equipment racks are arranged toface each other so that the cool air through the perforated floor tiles are drawn into the equipment cooling inlets in the rack. Hot air is expelled at the rear of the rack. Hot air is directed back to the air conditioning system within the data center.
