Data centers maintain some of the most tightly controlled indoor environments of any building type — temperature, humidity, and particulate levels are all managed within narrow bands for server reliability. Adding a staff kitchen or canteen introduces potential contamination sources that must be managed without any impact on server room air quality. Souniny ductless ESP provides a solution that keeps cooking emissions entirely within the kitchen envelope.
| Parameter | Specification |

| Redundancy | N+1 module configuration |
| Power | Dual supply (UPS-backed critical circuits) |
Application Scenarios
- Hyperscale data center campus (Virginia, USA): A major cloud provider’s data center campus with 2,000+ operations staff runs a 24/7 cafeteria in the administration building adjacent to the first server hall. The Heavy-duty Series ductless system maintains negative air pressure in the kitchen relative to the corridor — verified by differential pressure sensors linked to the BMS. The data center operations director specified that any kitchen air quality alarm automatically pages the on-call facilities engineer within 5 minutes.
- Colocation data center (Singapore): A colocation facility with client-accessible server rooms installed an Heavy-duty Series in the staff pantry/kitchen area. The client contract SLAs include indoor air quality parameters, and the colocation provider must demonstrate that kitchen operations do not affect server room air quality. Quarterly third-party air quality testing has shown zero detectable impact since kitchen commissioning.
- Financial services data center (London): A bank’s primary data center with a 200-person operations team uses Heavy-duty Series ESP with full HEPA and carbon treatment. The kitchen is physically isolated from the data hall by 3 sets of doors with interlocks, but the bank’s risk committee still required active air purification as an additional control. The system was validated during a 72-hour stress test where the kitchen operated at maximum capacity while particle counters in the data hall recorded zero deviation from baseline.
- Edge data center with micro-kitchen (Tokyo): A compact edge data center in central Tokyo with 10 operations staff has a micro-kitchen (microwave, induction hob, rice cooker) in a 6 m² space adjacent to the server room. A single Prince ESP-2000 handles the low cooking volume but must meet the same air quality standards as the main data center. The compact unit fits in a ceiling void above the kitchen, with only the intake grille visible.
