On-Site Space
Confirm dimensions, openings, equipment and personnel.

Engineering project
A ventilation retrofit around the teaching buildings and canteen. Silent cabinets and water-cooled fresh air units provide continuous fresh air, dust removal and cooling with low noise, while backward-curved cabinets handle canteen fume exhaust. The fresh air units carry multi-layer filters, the silent cabinets optimize duct structure to reduce airflow noise, and the backward-curved cabinets feature dynamically balanced impellers. The well-laid-out system minimizes duct losses for high ventilation efficiency.

Project challenge
Confirm dimensions, openings, equipment and personnel.
Locate fume, oil mist, odor or heat sources.
Plan the direction of fresh air in and pollution out.
Check duct resistance, noise, energy and maintenance.

Our solution
Zone the equipment by teaching area, canteen and venues, balancing airflow, operating noise and long-term maintenance.
Products used

Low-noise, vibration-isolated air supply for quiet areas like classrooms.

Delivers cooled fresh air to relieve stuffiness and stale air.

High pressure for long canteen exhaust duct runs.
