Steel and Foundry Industry

As an engineering leader, Indofan designs, fabricates, and commissions high-performance Air Pollution Control (APC) equipment and turnkey systems. Application demand rugged systems to handle extreme heat, explosive gases, and high dust loads. Indofan delivers advanced, custom-engineered technology built for ergonomic, economical, and efficient performance, ensuring full compliance with stringent government pollution control norms.

We engineer site-specific APC systems for the industry's most critical applications:

• Induction Furnaces (IF) & Electric Arc Furnaces (EAF): Comprehensive primary and secondary fume extraction for melting, charging, and tapping.
• Ladle Refining Furnaces (RF): Targeted extraction to capture emissions during alloy additions and deep refining.
• Argon Oxygen Decarburization (AOD): Heavy-duty gas systems built for intense chemical reactions and rapid flow variations.
• Foundry Shake-Out Grids & Core Rooms: High-volume capture to eliminate respirable crystalline silica and heavy particulates.
• Reclamation & Cooler Classifiers: Specialized dust extraction for hot, abrasive sand recycling loops.
• Sponge Iron (DRI) Process APC Equipment: Robust dust and gas handling systems engineered for punishing DRI plant environments.

Comprehensive System Engineering:
From Hood to Stack

Indofan engineers complete, optimized ecosystems consisting of:

• Source Capture: Custom extraction hoods (Doghouse-type, Swivel, Canopy, Side-draft, and Direct 4th-Hole systems).
• Thermal Mitigation: Forced Draft Coolers (Air-to-Air Gas Coolers) and mechanical Spark Arrestors to eliminate ignition hazards.
• Dry Filtration: Pulse-Jet Bag Filters, Cassette Filters, Cartridge Collectors, and heavy-duty Cyclones/Mechanical Dust Collectors.
• Wet Scrubbing: High-energy Venturi Scrubbers, Packed Bed Scrubbers, and Cyclonic Spray Towers.
• Air Moving Infrastructure: Precision-balanced ID & FD Fans, heavy-gauge Ducting, Automation and self-supporting Stacks/Chimneys.

Engineering-Led Retrofit Approach

We specialize in the retrofit, modernization, capacity enhancement, and performance optimization of existing dust collection and gas scrubbing systems across all furnace and process applications. Every retrofit project begins with a comprehensive site visit conducted by experienced APC engineers.

The assessment includes process evaluation, airflow analysis, emission source mapping, equipment condition assessment, and performance benchmarking. Based on the findings, a customized retrofit solution is engineered to maximize pollutant capture efficiency, ensure regulatory compliance, minimize downtime, and extend the service life of existing APC infrastructure.

Why Global Metal Producers Choose Indofan?

• Smart Energy Optimization: Uses High efficiency Blower and systems control and automation which scale extraction power based on real-time, cutting power costs by up to 10 - 20%.
• Severe-Duty Construction: Heavy-gauge plates, specialized internal wear liners, and heat-resistant steels withstand highly abrasive sand, iron ore, and hot gases.
• Guaranteed Norm Compliance: Safely brings stack emissions down to < 10 mg/Nm³, eliminating the risk of regulatory penalties or shutdowns.
• Low Lifecycle Maintenance: Optimized Design ratios and premium filter media prevent bag blinding and extend maintenance intervals.
