Enclosures

Custom Enclosures for Hot-Dip Galvanizing Operations

In any modern hot-dip galvanizing plant, effective containment of zinc vapors, acid mists, and airborne particulates is essential for worker safety, regulatory compliance, and process efficiency. The ANI Metal Enclosure Systems are engineered to fully surround critical process zones—such as pickling lines, kettles, and cooling sections—providing a controlled atmosphere that minimizes emissions, reduces noise, and protects both personnel and equipment.

Why Enclosures Are Vital in Galvanizing Plants

• Fume & Particulate Control: Encasing high-temperature kettles and acid baths captures zinc oxide fumes and acid spray, routing them into dedicated filtration or scrubbing systems to meet stringent environmental regulations.

• Temperature Management: Insulated panels help maintain stable process temperatures, reducing heat loss and improving energy efficiency in industrial galvanizing lines.

• Noise Reduction: Sound-attenuating materials dampen the roar of cranes, quench tanks, and dross removal equipment—creating a quieter, more comfortable work environment.

• Safety & Access: Integrated viewing windows, interlocked doors, and modular panels allow safe inspection and maintenance without exposing operators to hazards.

Key Features of ANI Metal Enclosures

Modular, Scalable Design
Prefabricated panels and frames let you configure enclosures around existing equipment or new installations—supporting future expansions without major downtime.

Corrosion-Resistant Construction
Panels combine acid-proof stainless steel exteriors with chemical-resistant liners, protecting against harsh galvanizing environments and extending service life.

High-Efficiency Seals & Gaskets
Specialized EPDM and fluoropolymer gaskets ensure airtight joints, preventing uncontrolled leaks of zinc oxide and acidic vapors.

Optional Integrated Ventilation
Pre-engineered duct connections simplify tie-in to bag filters, scrubbers, or heat exchangers—creating a turnkey fume-extraction solution.

Safety Interlocks & Monitoring
Door-switch interlocks, emergency-stop buttons, and continuous gas-detector compatibility help meet plant safety regulations and industry best practices.

Operational & Environmental Benefits

• Regulatory Compliance: Enclosures paired with extraction systems keep emissions well below permit limits and support ISO 14001 environmental management.

• Energy Savings: Insulation reduces heat loss from kettles and rinse sections, cutting fuel costs by up to 10 % in some installations.

• Improved Worker Health: Contained acid and fume exposure lowers respiratory hazards and ensures OSHA/ILO standards for indoor air quality.

• Reduced Maintenance: Protecting surrounding structures from corrosive vapors extends the lifespan of cranes, rails, and support steel.

• Process Stability: Temperature-controlled zones deliver more consistent zinc bath conditions for uniform zinc coating thickness.

Maintenance & Best Practices

• Quarterly Seal Inspections: Check panel gaskets for wear and replace any showing compression set or chemical damage.

• Annual Panel Cleaning: Wash interior surfaces to remove zinc buildup and acid residue, ensuring smooth panel mating.

• Ventilation Audit: Verify airflow rates and duct integrity every six months when enclosures tie into filtration systems.

• Safety System Testing: Test interlocks and emergency-stop circuits quarterly to maintain compliance with CE and NFPA standards.
