Case Study: DeAir Delivers 8 Heat-Pump Dehumidifiers to Secure a Massive Electrical Equipment Warehouse in Bac Ninh

Industrial B2B clients demand verified, real-world case studies before allocating capital to climate control infrastructure. In precision electronics manufacturing and power cable storage, humidity stands as the most aggressive vector of material degradation. Recently, DeAir successfully completed the commissioning of a comprehensive microclimate management system for a major electrical warehousing complex in Bac Ninh. Below is a technical review of how eight mobile DeAir.RE-600 units successfully neutralized the region's seasonal humidity challenges.

1. The Client's Challenge: Overcoming Seasonal Humidity in Northern Vietnam

Located in the highly industrialized Bac Ninh Province, the client's distribution facility manages thousands of tons of high-grade copper power cables and solid-state electronic sub-assemblies. Pure copper (Cu) and multi-layered circuit boards possess exceptionally low tolerances for airborne moisture.

During the transition seasons in Northern Vietnam, relative humidity (%RH) routinely reaches full saturation (exceeding 90%). Thermal mass differentials cause this airborne vapor to condense directly onto cold stored materials. Left unchecked, this induces cascading defects:

• Copper Core Oxidation: Bright metallic surfaces oxidize into dark copper oxides or greenish carbonates, degrading electrical conductivity and triggering QA/QC rejections by international buyers.
• Insulation Resistance Degradation: Moisture absorption into polymer wire jacket matrices causes a sharp decline in dielectric strength, elevating current leakage risks.
• Micro-Circuit Short Circuiting: Microscopic water droplets bridge conducting paths on printed circuit boards, inducing dendritic growth and catastrophic arcing even prior to power-up.

2. The DeAir Solution: High-Efficiency Heat-Pump Engineering & Stratified Deployment

Following comprehensive on-site psychrometric modeling, cubic volume evaluations, and door-opening duty-cycle calculations, DeAir's application engineers proposed a decentralized framework utilizing the DeAir.RE-600 Industrial Heat-Pump Dehumidifier.

 

 

The Decentralized 8-Unit Strategy: Rather than opting for a single, massive central Air Handling Unit (AHU) which requires extensive ductwork and introduces structural static pressure losses, DeAir recommended splitting the load into eight standalone RE-600 platforms. Strategically positioned at key intersections of the facility's aisleways, the units generate powerful convective cross-currents. This forces dry air directly through dense rack storage, ensuring no unconditioned dead zones remain.

3. Custom R&D Feature: Tailored Heavy-Duty Caster Wheels for Agile Operations

Typically, industrial dehumidifiers with high extraction ratings are built with rigid channel-iron bases designed for fixed, anchor-bolted installation alongside dedicated floor drains. However, to accommodate the dynamic layout requirements of a high-throughput logistics hub (where rack positioning and aisle configurations change frequently), DeAir's R&D division customized the structural architecture.

All eight RE-600 machines were engineered with a reinforced structural steel chassis integrated with four heavy-duty, 360-degree industrial swiveling caster wheels with integrated foot brakes. This custom mechanical upgrade yields substantial operational advantages for the facility managers:

• Agile Mobile Interception: Floor operators can quickly manually reposition the dehumidification clusters directly adjacent to localized high-humidity zones, such as open loading dock levelers or newly arrived unconditioned shipments.
• Simplified Facility Maintenance: The ability to roll the machinery away facilitates fast, unobstructed floor cleaning and epoxy coat maintenance, eliminating stagnant dust pockets underneath equipment.

4. Commissioning, Performance Verification, and Lifecycle Support

Immediately following electrical tie-ins and initial power-up, the DeAir.RE-600 cluster demonstrated rapid moisture draw-down. The units operated smoothly, pulling hundreds of liters of latent water from the atmosphere and safely stabilizing the indoor dew point. Surface condensation, musty odors, and hazardous floor sweating were entirely suppressed, providing an optimal preservation climate for the high-value power cable stock.

Procuring from DeAir—a specialized manufacturer with a production facility based directly in Vietnam (ISO 9001:2015 certified)—delivers essential long-term asset security. Factory-direct warranties, readily available spare components, and localized technical teams ensure the client completely avoids the long supply chain delays associated with imported climate control hardware.
