The trend toward “live cooking stations” in corporate cafeterias — where chefs prepare food to order in full view of employees — creates a fundamental tension: the visual appeal and freshness of live cooking versus the risk of cooking odors permeating adjacent open-plan workspaces. Souniny ductless purification provides the solution that HR, facilities, and employee satisfaction surveys all demand.

| Visual Design | Architectural integration — concealed or feature design |
| Power | Single-phase, standard office circuits |
Application Scenarios
- Tech company headquarters (Silicon Valley): A Google campus building with an open-plan cafeteria serving 2,000 employees daily features 4 live cooking stations (stir-fry, grill, pasta, omelette bar) in the center of the dining area. Each station has an Heavy-duty Series ductless purifier integrated into the counter design. Employee workstations begin 15 meters from the cooking stations. Quarterly air quality surveys show zero odor complaints from the engineering floor above, which was a major concern during cafeteria design.
- Financial services headquarters (London): A Canary Wharf tower with 5,000 employees operates a staff restaurant on the 10th floor with live cooking. The ductless approach was specified because the building’s façade is fully glazed with no louvre panels for exhaust discharge. The system recirculates cleaned air within the floor — a critical design requirement, as the financial trading floor on the 9th floor has zero tolerance for cooking odors in a high-stress environment.
- Co-working space cafe (Singapore): A premium co-working space with 500 members features an in-house cafe with hot food preparation. The Light-duty Series maintains air quality in the adjacent “quiet zone” where members take calls and focus-work. The facility manager installed real-time PM2.5 displays in the quiet zone — the reading has never exceeded 25 μg/m³, even during lunch rush.
- Pharmaceutical company campus (Switzerland): A pharma company’s headquarters with 3,000 employees installed an Heavy-duty Series system serving the main cafeteria. The specification was particularly rigorous because some research laboratories in the same building are sensitive to airborne contaminants. The ESP + HEPA + carbon configuration was validated by the company’s internal environmental monitoring team, who confirmed zero impact on laboratory air quality systems.
