Driers and Heat Exchangers

High-Efficiency Driers & Heat Exchangers for Galvanizing Plants

In a modern hot-dip galvanizing facility, controlling moisture and recovering heat is essential for maximizing throughput, ensuring consistent zinc adhesion, and minimizing energy costs. The ANI Metal Driers & Heat Exchangers lineup is engineered to rapidly remove residual water from pickled and rinsed parts, while reclaiming thermal energy from exhaust gases—delivering both environmental compliance and long-term operational savings.

Why You Need Driers & Heat Exchangers

After a part exits the final rinse tank, even microscopic water droplets can cause defects—pinholes, gas blistering, or uneven coatings—when immersed in molten zinc. At the same time, hot exhaust air and steam carry away valuable heat energy. By integrating purpose-built industrial driers and shell-and-tube or plate-type heat exchangers, galvanizing plants can:

• Eliminate water-induced coating flaws for uniform zinc films.

• Reduce furnace heat-up time, thanks to preheated parts and reclaimed exhaust heat.

• Cut fuel and electricity bills by up to 25 % through energy recovery.

Key Features of ANI Metal Systems

Custom-Sized Drying Chambers
Modular conveyorized tunnels fit your basket sizes and line speed. High-velocity air nozzles deliver targeted, uniform drying without mechanical blowers inside the zinc kettle.

High-Efficiency Heat Exchangers
Our shell-and-tube exchangers recover waste heat from fume exhaust and boiler blowdown, preheating incoming combustion air or process water. Plate-type units offer compact footprints for retrofit installations.

Advanced Controls & Monitoring
Central PLC interfaces regulate air temperature, flow rate, and exhaust pressure. Integrated sensors track dew point and thermal efficiency in real time, ensuring peak performance.

Corrosion-Resistant Construction
All wetted surfaces use stainless steel or acid-proof alloys to withstand pickling acid traces and zinc vapors—minimizing maintenance and prolonging service life.

Easy Maintenance Access
Swing-open housings, removable filter panels, and bolted tube bundles allow rapid inspection and cleaning without major line shutdowns.

Operational & Environmental Benefits

• Superior Coating Quality: Bone-dry parts enter the galvanizing bath, eliminating common defects and reducing scrap.

• Energy Savings: Heat recovery slashes fuel consumption in dry-off and preheat stages by recovering up to 60 % of exhaust heat.

• Faster Cycle Times: Preheated, moisture-free parts require less time to reach bath temperature, boosting daily throughput.

• Regulatory Compliance: Lower exhaust temperatures and reduced steam emissions help meet local air-quality standards and ISO 14001 guidelines.

• Lower Maintenance Costs: Durable filter media and tube bundles with anti-fouling coatings extend service intervals by 30 %.

Maintenance Best Practices

Monthly Filter Inspections: Clean or replace air intake and exhaust filters to maintain airflow and heat-exchange efficiency.

Quarterly Tube-Bundle Checks: Monitor fouling in shell-and-tube exchangers; schedule chemical or mechanical cleaning when thermal performance drops by >10 %.

Annual Control Calibration: Verify sensor accuracy for temperature, pressure, and dew-point readings to ensure reliable PLC operation.

Lubricate Bearings & Fans: Apply high-temperature grease every 1,000 operating hours to keep blowers and motor bearings in top condition.
