Patent 11988434 was granted and assigned to Tippmann Engineering on May, 2024 by the United States Patent and Trademark Office.
A high efficiency airflow management system can be used to reliably and consistently draw air through palletized product stacks with a minimum of energy expenditure. A racking system is provided with a grid of pallet bays separated from an air plenum/chamber by a wall having an airflow opening for each pallet bay. An air dam selectively permits or prevents airflow through portions of the airflow opening such that airflow may be allowed to flow through the entire opening, only a portion of the opening, or none of the opening.
