Supermarket hot food counters — rotisserie chicken, fried foods, prepared meals, deli — generate cooking emissions in the middle of a retail environment where air quality directly affects customer dwell time and purchasing behavior. The challenge is to contain cooking emissions within the food preparation zone without the noise, appearance, or HVAC impact of industrial kitchen equipment.

Application Scenarios
- Supermarket hot food section (Australia): A Woolworths store in Sydney installed two Light-duty Series units at the in-store hot food counter (roast chicken, hot chips, prepared meals). The counter is in an open area of the store with no walls. The ductless purifiers are mounted under the counter with intake grilles below the hot food display. Store management reports that the “fresh bakery” aroma from the adjacent bread section is no longer contaminated by fried food smells — a specific customer complaint that had been recurring for years.
- Hypermarket prepared foods (Thailand): A Big C hypermarket in Bangkok with a large prepared food zone (stir-fry station, curry station, fried foods) uses 4 Light-duty Series units in a coordinated array. The units are ceiling-suspended with a custom hood designed to match the store’s interior design palette. The store’s facility manager notes that air conditioning energy consumption actually decreased after installation — because the previous exhaust fans had been pulling conditioned air out of the store, forcing the AC to work harder.
- Convenience store hot food (Taiwan): A FamilyMart in Taipei with a small hot food counter (fried chicken, steamed buns, tea eggs) uses a single Light-duty Series. The store is only 80 m², and previously, hot food smells would permeate the entire space — including packaged snacks on shelves that could absorb odors. The Light-duty Series eliminated the cross-contamination issue completely. Store staff also reported that their uniforms no longer needed daily washing.
- Premium food hall counter (London): A high-end food hall in a department store uses Light-duty Series units built into the counter design for the hot food section. The store’s visual merchandising team was closely involved in the installation to ensure the purification equipment was completely invisible to customers. The stainless ducting is concealed within the counter carcass, with only the intake grille visible — designed to look like a standard architectural feature.
