What air handling units (AHU) 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.
Controls upgrade
New controls, sensors and BMS integration.
Planned servicing
Filters, belts, coils, drains and controls on a schedule.
Like-for-like replacement
New unit in the same position, connected to existing ductwork.
