    Pfannenberg announces the DHS Hybrid Series (DHX 34X1). This closed-loop system combines free cooling and active cooling to safeguard critical electronics within an enclosure while lowering energy consumption, cutting costs, and reducing carbon emissions.

    Free cooling minimizes energy use by using the cooler air outside the enclosure to remove heat, while active cooling utilizes a compressor and refrigerant cycle to cool the air in the enclosure when it exceeds the desired temperature. The combination optimizes the efficiency of the unit, reducing energy usage. The dual system also provides redundancy in a single unit to avoid downtime. Choose from indoors (Type 12), outdoors (Type 3R/4), and in washdown (Type 4X) configurations. Units are ideal for locations with lower ambient temperatures, climate controlled facilities, and operations that periodically run at partial capacity.
