ExhaustFlow Technologies announced a patented airflow management system that delivers up to 25 percent more cooling capa
ExhaustFlow Technologies, a Salem, New Hampshire-based company, announced on July 14, 2026 the broad availability of its integrated base system for air-cooled chiller plants. The system addresses condenser air recirculation, a persistent problem in high-density chiller installations that silently degrades performance and forces operators to add equipment and energy capacity.
In dense air-cooled chiller arrays, hot discharge air from one unit recirculates back into the condenser intake of neighboring units, causing condenser inlet temperatures to run 10 to 30 degrees Fahrenheit above actual ambient conditions. This degrades chiller capacity, increases electrical demand, and forces operators to oversize equipment to compensate for performance losses. As artificial intelligence workloads drive heat rejection densities higher, the recirculation effect worsens, leading operators to respond with additional equipment and higher energy costs rather than addressing the root cause.
The company's patented integrated base system, protected under U.S. Patent No. 12,372,268, captures and routes clean ambient air from outside the recirculation zone, displacing hot discharge air before it re-enters the chiller condenser intake. The result is uniform inlet temperature conditions across the entire chiller array, as if each unit were operating as a standalone installation with no neighboring thermal interference. According to EFT's Computational Fluid Dynamics modeling, the system delivers up to 25 percent more cooling capacity without water consumption, without modifying chiller internals or controls, and without requiring equipment downtime for retrofit installations.
Ralph Breisch, SVP of Global Sales and Marketing at ExhaustFlow Technologies, stated, "The data center industry is spending significant capital responding to AI-driven density growth. In many cases, operators are solving the wrong problem. The chiller is not the constraint. The air around it is. EFT addresses that directly -- from the same equipment that is already in the ground."
The system is designed for both new construction and retrofit installations. On May 19, 2026, engineers and data center owners at Multistack LLC headquarters in Sparta, Wisconsin witnessed a demonstration, with Doyle Freeman, President of Spartan Critical Systems, describing the results as unrivaled. Since launching publicly in June 2026, ExhaustFlow Technologies has received independent editorial coverage from Climate Control News, Refrigeration Industry, and The Data Center Engineer, and is in active discussions with several major data center operators.
