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

Engineering project
A ventilation retrofit designed around the high noise and air-quality requirements of primary school pupils. Silent cabinets with multi-layer sound absorption run quietly in the plant room without disturbing teaching, while water-cooled fresh air units pretreat, cool and filter outdoor air to improve classroom conditions. Backward-curved cabinets provide strong pressure for fast canteen fume discharge. All equipment sits on vibration-isolation bases, and the zoned control adjusts airflow flexibly by teaching period.

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.
