KTJ Silent Fresh Air Cabinet
Low-noise operation for quiet guest rooms.

Engineering project
A long-term rental…
01 Background
A long-term rental apartment with relatively enclosed corridors, common areas and units. Silent cabinets and water-cooled fresh air units form the common-area fresh-air circulation system. The silent cabinets run with low vibration and noise, and the fresh air units deliver cooled air to speed air movement and relieve dampness and odor. A small centrifugal fan assists exhaust for the shops. The system runs 24 hours to optimize the whole apartment environment and tenant comfort.
Ventilation equipment zoned for guest rooms, lobbies and dining areas with fresh air, quiet and exhaust needs.

02 On-Site Problems
Closed guest rooms with poor airflow, stuffiness and odor; common areas and dining zones needing zoned ventilation; and high noise requirements.
03 Equipment Used

Low-noise operation for quiet guest rooms.

Delivers cooled, clean fresh air.

Extracts dining-area fume to prevent odor spread.

04 Our Solution
Guest rooms focus on quiet fresh air and dining areas on fume extraction, running independently around the clock.
05 Installation Process
Silent cabinets are placed in plant rooms or ceilings, fresh-air units distribute air to rooms, and dining-area cabinets connect to hoods and ducts, all vibration-isolated with zoned ducting to fit existing hotel services.
06 Results
Continuous fresh air in rooms, less odor, better common-area circulation, smooth dining exhaust, and quiet operation that protects guest rest for an improved stay.
