What the work involves
Many AHUs in older offices, schools and retail units run on belt-driven fans, clogged filters and controls nobody understands. 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.
EC fan retrofit
Belt-driven fans replaced with direct-drive EC fans.
Controls upgrade
New controls, sensors and BMS integration.
Planned servicing
