Crac Hoods

The Cool Shield CRAC Extension is designed to be a highly effective, customizable and cost-effective solution for extending your cooling unit return up to the return plenum. Creating this direct connection allows the cooling unit to receive warmer air which provides significant benefits for your data center cooling.

Higher return temperatures can improve cooling capacity and efficiency. The capacity of a cooling unit can vary significantly based on the return temperature. For example, the actual capacity of a 50-ton cooling unit can range from 20-tons to 70-tons based on the return temperature provided. Studies have shown a 10-degree increase return air
temperature to cooling unit can result in up to 30% capacity increase. This increase in capacity can have a cascading effect on energy efficiency across the data center to significantly reduce cooling costs.
