[Case Study] Rust Prevention Solution for Precision Engineering Warehouse in Bac Giang With DeAir.RE-600 Dehumidifier

In the precision engineering industry, humidity is the silent but most destructive enemy. Oxidation and rust can degrade quality, alter technical specifications, and cause severe economic losses to high-value metal raw materials. Recognizing this risk, HSV Precision Engineering Company in Bac Giang proactively sought a professional humidity control solution, and DeAir is proud to have been chosen to tackle this critical challenge.

1. Problem Analysis at HSV Factory's Raw Material Warehouse

The challenge faced by HSV, a reputable partner in the precision engineering sector in Bac Giang, was how to protect its 160m² raw material warehouse with a height of 4m (total volume of 640 m³). This facility stores high-value steels, alloys, and metal components that are core inputs for the entire production line. Even a minor lapse in environmental control could lead to irreversible damage, directly impacting final product quality and the company's reputation.

Strict technical requirements were set to ensure the quality of raw materials:

• Relative Humidity (RH): Must be consistently maintained at below 60%. This is a critical safety threshold because the processes of oxidation and metal rusting are significantly inhibited when air humidity is below this level. According to experts, high humidity is the leading environmental factor that accelerates metal corrosion.
• Temperature: Stable within the range of 20-26°C, creating an ideal storage environment and preventing material deformation due to sudden temperature changes, which could affect product accuracy.

2. DeAir's Expert Solution: A System of 2 DeAir.RE-600 Dehumidifiers

After a thorough on-site survey and detailed latent load calculations, DeAir's engineers proposed and implemented a solution involving the installation of 2 DeAir.RE-600 industrial dehumidifiers. This selection was based on in-depth technical analysis and practical project experience:

• Powerful Dehumidification Capacity: Each DeAir.RE-600 unit boasts a dehumidification capacity of up to 600 liters/day and an airflow of 6,000 m³/h. A dual-unit system ensures rapid humidity reduction and maintains stable, uniform conditions throughout the warehouse, even during Northern Vietnam's harsh humid seasons or when warehouse doors are frequently opened for shipping and receiving.
• Energy-Optimizing Heat Pump Technology: This is the key factor for optimizing long-term investment and operating costs. The heat pump technology not only effectively removes moisture but also reuses the heat generated during the process. This helps maintain a stable room temperature within the required range (20-26°C) without the need for auxiliary heaters or the excessive cooling and high electricity consumption of air conditioners.
• Durable and Reliable Operation: As a "Made in Vietnam" product line, the DeAir.RE-600 is built with high-quality materials and stringent quality control processes, ensuring durable and stable performance in Vietnam's tropical humid climate and industrial factory environments.

4. Actual Results: Absolute Material Protection, Optimized Costs

After installation, the DeAir technical team conducted thorough testing, measurements, and a detailed handover to the HSV factory. The actual results showed that the system of two DeAir.RE-600 units performed perfectly, consistently maintaining the warehouse humidity below the 60% RH threshold and the temperature stable at 20-26°C, fully meeting and exceeding HSV's expectations.

The benefits that DeAir's solution brought to the HSV factory are clear:

• 100% Protection of Material Value: Completely eliminates the risk of rust and corrosion, preserving the quality and value of the inventory.
• Guaranteed Production Quality: Standard-compliant raw materials provide a solid foundation for high-quality precision mechanical products, reducing waste.
• Operating Cost Savings: The superior energy efficiency of the Heat-Pump technology significantly reduces monthly electricity bills compared to traditional humidity control solutions.
• Peace of Mind and Proactivity: The factory management can have complete peace of mind regarding storage conditions, allowing them to focus resources on core production and business activities.
