An excellent way of handling the typical “hot aisle, cold aisle” arrangement in data centers is a system designed around variable air distribution. Adjustable nozzles, combined with our patented internal dampers that can be opened and closed, deliver a user-controlled variable air distribution that can be modulated based on server demand and heat load.
Another effective option uses a rectangular duct for a negative pressure application. When used on a hot aisle, the rectangular duct provides full linear extraction of hot air from the entire aisle—a major advantage over pulling it into the main return through spot grilles. Linear extraction improves the efficiency of heat removal, which reduces both the amount and the temperature of supply air needed, lowering overall energy costs.
