Air tight heat exchangers for duct execution
Air tight heat exchangers are designed to eliminate or minimize air leakage between the treated airflow and the surrounding environment.
They are ideal for direct duct installations, either supply or return, in applications where air quality and system tightness are critical – such as laboratories, hospitals, clean rooms, and controlled contamination facilities.
Each unit is built with a high level of mechanical integration, ensuring reliability, operational safety, and compliance with the most stringent specifications.
