[Case Study] Rust Prevention Solution for the Metal Industry with Olmas OS-500 Industrial Dehumidifier

1. Context: The Challenge of High Humidity at a Metal Fabrication Plant in Nam Dinh

In May 2023, DeAir took on a challenging project for a key partner: a factory specializing in metal product manufacturing and fabrication in Nam Dinh province. Located in the characteristic tropical monsoon climate of Northern Vietnam, the factory frequently faced high humidity levels, sometimes exceeding 85%.

The Client's Problem:

• Product Damage: Metal billets, machined parts, and finished products were constantly oxidizing, leading to surface tarnishing and rust shortly after being stored.
• Increased Costs: The company incurred significant expenses in labor, chemicals, and time to re-polish and rework faulty products before shipment.
• Reputation Impact: This situation not only degraded product quality but also caused delivery delays, directly affecting their reputation with major partners.

Faced with this situation, the client approached DeAir with an urgent request: to implement an automatic, effective, and durable humidity control solution for their entire production and storage area.

2. DeAir's Solution: Implementing the Olmas OS-500 Industrial Dehumidifier

After conducting an on-site survey to assess the factory's area, moisture load, and air circulation, DeAir's team of experts proposed an optimal solution.

The Proposed Solution:

We recommended and implemented the Olmas OS-500 industrial dehumidifier. This model was selected based on a thorough analysis of the factory's specific needs:

• Powerful Capacity: With a dehumidification capacity of up to 500 liters per day, the unit is fully capable of controlling humidity in a large-scale workshop, quickly bringing moisture levels down to a safe threshold.
• Durable Industrial Design: The Olmas OS-500 features a high-performance compressor from a leading brand, ensuring stable 24/7 operation. Crucially, its cooling coil is coated with an anti-corrosion layer, extending its lifespan in the harsh environment of a metal factory.
• Intelligent Control: The machine allows for setting and maintaining humidity within a safe range (below 50% RH), operating automatically to protect materials continuously while saving energy.

The installation and handover were carried out quickly and professionally by DeAir's technical team, ensuring no disruption to the factory's production schedule.

3. Outstanding Results: Ending Rust Worries, Enhancing Product Quality

Shortly after becoming operational, DeAir's solution demonstrated clear and effective results.

The Achieved Results:

• The humidity in the workshop is now consistently maintained below 50% RH, even during peak humid seasons.
• The issue of metal products tarnishing and rusting during storage has been completely eliminated.
• The quality of the final products is consistently guaranteed, meeting the strictest standards.
• The company has saved a significant amount of money on reworking faulty products, thereby optimizing profitability.

4. Why is a Dehumidifier a Vital Asset for the Metal Industry?

Scientific studies show that the process of metal corrosion (rusting) accelerates dramatically when the relative humidity (RH) in the air exceeds the 50-60% threshold. Vietnam's hot and humid climate provides the "ideal" environment for corrosion, causing silent but massive losses for businesses in metal manufacturing, processing, and storage.

Investing in a professional humidity control system like the Olmas industrial dehumidifier is not just a temporary fix; it is a strategic investment to protect assets, enhance product quality, and strengthen competitive advantage in the market.
