The Challenge

Why Food Courts Need Centralized Exhaust Purification

Managing kitchen exhaust across 20–60+ independent cooking stalls — each with different menus, hours, and cooking intensities — creates unique challenges that no single stall owner can solve alone. A food court is effectively dozens of commercial kitchens sharing one roof — and one exhaust system.

Multi-Tenant Exhaust Management

Each food court stall generates its own exhaust stream — Chinese wok, Thai stir-fry, Korean BBQ, deep fryer, and pizza oven all running simultaneously. Without a unified exhaust architecture, individual stall exhausts conflict, recirculate, and create hot spots. Grease accumulates at different rates in different duct branches, making fire risk unpredictable and maintenance chaotic.

Massive Airflow Volumes

A 30-stall food court generating 1,500 m³/h per stall requires 45,000 m³/h of total exhaust capacity — equivalent to 15 large standalone restaurants. Traditional grease filters at this scale require hundreds of filter panels, daily monitoring, and weekly replacement during peak trading. The maintenance labor cost alone is substantial for a mid-size food court, and exhaust at this scale must stay balanced with make-up air units serving the dining area.

Tenant Compliance & Lease Enforcement

Shopping mall leases typically require tenants to maintain compliant kitchen exhaust. But with individual stall exhaust, there is no objective way to measure each tenant’s contribution to the shared system or verify compliance. Fire authority inspections that cite the food court’s shared exhaust shaft create liability for the mall operator, not just the offending tenant.

Odor Spillage into Retail Areas

Cooking odors migrating from the food court into adjacent retail corridors, anchor stores, and cinema lobbies are a frequent tenant complaint in shopping malls and a constant indoor air quality concern. According to ASHRAE Handbook guidelines, grease-laden air that escapes the exhaust system rather than being captured creates a persistent, worsening odor problem that traditional kitchen ventilation systems struggle to address.

Working Principle

How Electrostatic Purification Works in a Food Court Exhaust System

Polygee ESP uses a multi-stage purification process — from pre-filtration to UV sterilization — with third-party tested grease removal for food court kitchens: 97.6% on LK160 and 97.0% on LK40 (Beijing Zhongyan Huanneng, CMA — reports ZY05W230298 / ZY05W230296); 96.0% at rated airflow on LK120 (SQEP, CMA — report 2024I20-35-5322488001).

Application Scenarios

Food Court Ventilation Configured for Every Layout

From traditional inline food courts to premium food halls and ghost kitchen clusters — our ESP solutions are configured for each format’s specific commercial kitchen exhaust architecture.

Shopping mall inline food court with 30+ stalls sharing centralized ESP exhaust shaft

Shopping Mall Inline Food Court

The typical format: 20–60 stalls arranged in rows around a shared seating area, all connected to one central exhaust riser. Polygee deploys 1–2 high-capacity ESP units at the shaft base, purifying the entire combined airflow before rooftop discharge — a cost-efficient setup for uniform stall layouts.

Open-plan food court with freestanding island cooking stalls and distributed ESP zones

Island Stalls & Open-Plan Layout

Freestanding island kiosks in open atrium spaces lack direct access to a central shaft. Polygee uses a distributed ESP cluster approach — one compact unit per cooking zone — with flexible duct routing to multiple risers. This zone-by-zone design allows individual stall changes or cuisine upgrades without re-engineering the entire exhaust system.

Zone-by-Zone · Flexible Duct Routing
Ghost kitchen cluster with dense stainless steel cooking stations and heavy-duty ESP ventilation

Ghost Kitchen & Cloud Kitchen Cluster

Delivery-only kitchen clusters operate 18–24 hours with peak-hour cooking intensity far exceeding traditional food courts. Basement or back-of-house locations leave little tolerance for grease leakage. Polygee provides hot-swappable ESP modules with redundant capacity, enabling cell-by-cell cleaning without closing stalls.

FAQ

Frequently Asked Questions

The usual approach is a centralized ESP architecture: all stalls connect to a shared exhaust shaft, with one or more large ESP units installed in the main duct riser. Each stall’s cooking load contributes to the combined airflow, and the ESP handles the total volume. Alternatively, stall clusters (e.g., Asian, Western, desserts) can each have their own ESP unit for independent management.
Centralized ESP: all stalls share a main exhaust shaft with one or two large ESP units. Lower total equipment cost, simpler maintenance, but one unit failure affects all stalls. Decentralized ESP: each stall or stall cluster has its own ESP unit. Higher flexibility and fault isolation, but higher total cost. Most malls use a hybrid approach: central shaft with ESP clusters per cooking zone.
A 30-stall food court typically requires 30,000–50,000 m³/h of total exhaust purification capacity. Each stall generates 800–2,000 m³/h depending on cooking type (light snacks vs. heavy wok cooking). Our engineers calculate the diversity factor — not all stalls cook at full capacity simultaneously — and size the ESP system accordingly.
A centralized ESP system naturally enforces compliance — all tenant exhaust passes through the same purification system before discharge. Individual stall dampers and airflow sensors can monitor each tenant’s contribution. Monthly performance reports from the IoT dashboard can be shared with tenants as part of lease compliance documentation.
ESP removes up to 97.6% of grease and smoke particles, removing the visible exhaust plume and the primary carrier of cooking odors. For further odor control (gaseous compounds that pass through ESP), we recommend adding a kitchen exhaust activated carbon filter or a UV kitchen odor control module downstream of the ESP. This combination substantially reduces cooking odor migration into retail corridors and anchor stores.
Requirements vary by country and local fire authority. The LK in-duct series carries CE certification (FQC2602501); 6K/12K/18K models are UL Listed (UL 867, File E522667); the LK series is RoHS compliant; plus CQC, CCEP, ISO 9001, ISO 14001 and ISO 45001. We export to 50 countries and provide compliance documentation on request — for building authority submissions, fire authority reviews, and mall brand standards.
Yes. For new malls under construction, ESP is installed as part of the MEP fit-out. For existing food courts, ESP units are installed in the main duct risers during phased nighttime works — typically 2–5 nights per duct riser, with no impact on stall operations during trading hours.
For a busy food court, ESP cells typically require cleaning every 2–4 weeks. With centralized ESP, maintenance is performed on one unit at a time while others remain operational. Cells are removed, soaked in alkaline degreaser, rinsed, and reinstalled — typically 1–2 hours per unit. IoT monitoring alerts the team when efficiency drops below threshold, removing guesswork.
No. The ESP adds only a small and stable resistance to the exhaust path, so the existing ventilation system design — exhaust fans, make-up air units, and control dampers — keeps operating as engineered. Polygee provides pressure-drop data for your MEP consultant to confirm fan selection.
