For restaurant chains with 50, 100, or 500+ locations, air purification is not an individual store decision — it is a corporate engineering standard that must work across diverse building types, local regulations, and climate zones. Standardizing on Souniny ESP provides consistency in equipment specification, maintenance procedures, and compliance documentation across the entire portfolio.
| Parameter | Specification |
|---|---|
| Approach | Standardized specification by store type (mall, street-front, dark kitchen) |
| Equipment Specification | Corporate-approved SKU list by cooking volume |
| Maintenance | National/regional service contracts with standardized procedures |
| Compliance | Centralized monitoring dashboard via MODBUS |
| Training | Franchisee training module + maintenance video library |
| Spare Parts | Regional parts depots for <24-hour delivery |
Application Scenarios
- Korean BBQ chain (40+ locations, nationwide): A Korean BBQ chain with locations across South Korea standardized on Heavy-duty Series ducted ESP for all new stores and retrofits. Corporate engineering developed a store classification system (Type A: standalone building, Type B: mall unit, Type C: basement) with a specific ESP configuration for each. The standardized approach reduced equipment procurement costs by 25% through bulk purchasing and cut average installation time from 2 weeks to 5 days.
- Hot pot chain (200+ locations, China): A major hot pot chain operating across China specified Souniny Heavy-duty Series for all locations. The corporate facilities team maintains a centralized monitoring dashboard that receives real-time ESP performance data from every store via 4G cellular MODBUS gateways. Stores with declining ESP performance automatically generate a maintenance ticket. The system has reduced emergency maintenance calls by 70% and eliminated unplanned kitchen closures due to exhaust failures.
- Pizza chain international expansion (Middle East): An American pizza chain expanding into the Middle East market specified ductless Light-duty Series for mall-based locations. The franchise agreement with the master franchisee included a mandatory equipment package that covered kitchen ventilation. The standardized approach meant franchisees in Dubai, Riyadh, and Kuwait City all received identical equipment with identical maintenance schedules — simplifying the master franchisee’s support operations.
- Fried chicken franchise (UK): A rapidly growing fried chicken franchise with 80+ UK locations uses Heavy-duty Series duckless units as standard equipment. The franchise operations manual includes a 15-minute video training module on ESP maintenance, and each franchisee signs a maintenance log that is reviewed during quarterly quality audits. The operations director reports that the 3 stores with the worst air quality scores before ESP installation are now among the top 10 performers.
