What air handling units (AHU) involves
Replacing the fan section with EC fans, or the whole unit with a modern heat recovery AHU, can cut running costs and noise while restoring airflow. New units must meet current ecodesign rules for fan efficiency and heat recovery. Replacements often involve crane lifts, roof work and out-of-hours changeovers.
