Ductwork for Industrial Kitchens: Safe, Efficient, and Inspection-Ready Grease Extraction

The extraction of grease and vapors in industrial kitchens requires ducts and accessories designed for high temperatures, grease load, and frequent cleaning. At GG123 Mexico, we integrate BIM modeling, automated machinery, and a complete portfolio (square/rectangular ducts, spiroducts, fittings, elbows, and reducers) to deliver a safe, airtight, and easy-to-maintain solution — with national and international coverage across Latin America.

The technical and business challenge

Fire risk and maintenance downtime

Grease buildup inside ducts increases the risk of fire and causes downtime due to unplanned cleanings. Geometry, gauge, and sealing directly affect grease accumulation and ease of maintenance.

Airtightness and system performance

Leaks and turbulence reduce draft, increase energy consumption, and contaminate unintended areas. A tight, properly sized, and balanced duct system is required to maintain the designed extraction flow.

Our solution for industrial kitchens

1) Engineering and BIM modeling

In BIM, we model plenums, main ducts, and branches with clash detection against other disciplines (electrical, sprinklers, gas). We generate a numbered breakdown by zone for prefabrication and just-in-time logistics, reducing rework and shortening installation times.

2) Manufacturing with automated machinery

Our automated machinery ensures precise tolerances, uniform seams and flanges, and consistent seals. This improves airtightness, reduces grease accumulation at joints, and simplifies cleaning.

3) Materials and construction details

• Gauge and reinforcement according to system dimensions, temperature, and pressure.
• Inspection doors strategically located for cleaning and verification.
• Smooth transitions and proper radii to minimize turbulence.

4) Logistics, delivery, and installation

We package by work front with edge protection and labeled sections, ready to install. We coordinate JIT delivery windows to avoid congestion in operational areas.

Concrete benefits for your operation

• Use of BIM technology: better coordination and fewer interferences.
• Cost savings: reduced rework, fewer leaks, and lower energy consumption.
• Time reduction: prefabrication and sequenced deliveries.
• Automated machinery: consistent quality and reliable seals.
• Comprehensive solutions: engineering, manufacturing, logistics, and on-site support.
• Product variety: square/rectangular ducts, spiroducts, fittings, elbows, reducers.

Use cases

Restaurants and hotels

Ducts designed for continuous service, with inspection access and easy cleaning.

Industrial cafeterias and dark kitchens

Compact, balanced networks for multiple cooking lines in limited spaces.

Shopping centers and food courts

Modular solutions for future expansion and coordination with sprinklers and general exhaust systems.

Best practices for operation and maintenance

• Schedule periodic cleaning of filters, hoods, and ducts.
• Check seals and joints after every intensive cleaning.
• Balance and measure airflow to maintain performance.
