01 Background
A larger seafood restaurant with heavy exhaust from the processing and cooking areas. High-pressure cabinets form a large exhaust system, centrifugal fans assist the kitchen, water-cooled fresh air units serve the front hall, and commercial kitchen AC units cool the whole kitchen. The high-pressure cabinets handle high fume flow, the centrifugal fans strengthen local exhaust, the fresh air units improve the front hall, and the kitchen AC units cool multiple stations. The large zoned system supports peak-hour operation.
Exhaust, fresh air and cooling equipment configured for barbecue and restaurant venues with heavy oil fume, stuffy dining halls and hot kitchens.

02 On-Site Problems
Heavy, concentrated barbecue and wok fume at mealtimes; hot, stuffy kitchens; smoke and odor lingering in the dining hall; and ducting with many bends and high resistance.
03 Equipment Used

High pressure to quickly extract barbecue and cooking fume.

High static pressure for multi-bend exhaust ducts.

Spot-cooling for kitchen stations in hot environments.

04 Our Solution
Select by exhaust volume, duct resistance and dining-area comfort, preventing fume spillover while keeping the hall cool and the kitchen temperate.
05 Installation Process
Backward-curved or high-pressure cabinets are ceiling- or roof-mounted and connected to the main exhaust duct, fresh-air units supply the hall, and kitchen AC units are placed at cooking stations in a compact store layout.
06 Results
Fume discharges quickly, hall smoke is clearly reduced, kitchen and dining temperatures drop, and odors no longer spread for a fresh, comfortable environment through long operating hours.
