Context: An export garment company in Hai Phong needed strict humidity control in its workspace, but indoor production space was extremely limited.
The Challenge: No floor space available for a large-capacity dehumidifier. The solution had to occupy zero production area while ensuring high dehumidification efficiency and easy operation.
The Solution: DeAir designed a custom outdoor installation for the DeAir.RE-1200 (protected by a dedicated canopy), connecting supply and return ducts into the room. Uniquely, the control panel was customized to be mounted on the side.
The Result: 100% savings of valuable indoor production space, highly effective humidity control, and exceptionally convenient operation and maintenance.
1. The "Space" Problem at the Hai Phong Garment Factory
1.1. The Reality of Export Garment Manufacturing
In the export garment industry, every square meter of factory floor is "gold." Space must be absolutely optimized for sewing lines, cutting tables, and fabric storage. Simultaneously, high humidity (especially during Northern Vietnam's humid "nom" season) is the number one enemy, causing fabric mold, weakening seams, and damaging finished goods.
1.2. The "Catch-22" Dilemma
⚠️ CRITICAL ISSUES TO RESOLVE
Severe Space Constraints: No indoor area available to house a high-capacity (1200 kg/day) dehumidifier.
Strict Performance Requirements: Workspace humidity must still be tightly controlled at 45-55% RH to meet export quality standards.
Operational Feasibility: The alternative solution must remain easy for staff to operate and convenient for technicians to maintain without halting production.
Instead of forcing the client to sacrifice valuable production space, DeAir's engineering team proposed a creative, "tailor-made" solution: move the machine outdoors and duct the conditioned air inside.
🔧 SPECIALIZED INSTALLATION DESIGN
Location: The DeAir.RE-1200 is placed on a reinforced concrete base outside the factory, protected by a dedicated metal canopy to shield it from direct rain and sun.
Ducting System:
Return Duct: Pulls humid air from inside the workspace out to the machine.
Supply Duct: Pushes dry, dehumidified air back into the room.
Customized Control Panel: Instead of the standard front-facing position, the control panel for this specific project was ingeniously relocated to the side of the unit, facing a convenient walkway.
3. Advantages of Outdoor Installation
Absolute Space Saving: 100% of the indoor factory floor is preserved for production lines and inventory storage.
Superior Machine Protection & Cooling: The outdoor environment offers better ambient air circulation for heat dissipation, while the custom canopy prevents weather-related damage.
Zero-Disruption Maintenance: Technicians can access, clean, and service the unit from the outside without entering the production floor or interrupting workers.
Enhanced Operational Convenience: The side-mounted control panel allows staff to easily monitor parameters and make adjustments without navigating around bulky ductwork or the main machine casing.
4. Real-World Implementation Process
4.1. Survey and Design
DeAir meticulously measured the outdoor installation site, calculated the optimal duct diameter and length to prevent pressure drop, and designed a canopy that seamlessly integrated with the factory's architecture.
4.2. Preparation and Installation
The DeAir.RE-1200 is installed outdoors under a protective canopy, connected to the indoor workspace via professional supply and return ducting.
The installation was executed systematically: building a load-bearing base, erecting the canopy, positioning the unit, and connecting the ducting system along with an automatic condensate drainage line routed safely outdoors.
4.3. Smart Design Detail
Close-up of the control panel custom-mounted on the side, allowing easy operation without needing to access the front of the machine.
Relocating the control panel to the side is a key technical highlight. It allows operators to view the display and press buttons effortlessly, unhindered by the machine's main casing or the ducting system.
Factory staff can easily operate and monitor the machine thanks to the intuitive, conveniently placed control panel.
4.4. Commissioning and Handover
The system was rigorously tested for duct airtightness, and airflow and target humidity were precisely calibrated. DeAir provided hands-on training to the factory staff on safe and efficient operation before the official handover.
5. Achieved Results
5.1. Technical Performance
Workspace humidity is stably maintained at 45-55% RH.
The ducting system operates quietly and efficiently, with no air leaks or pressure drops.
The machine operates stably and durably despite being located outdoors.
5.2. Space and Operational Benefits
100% of production space is preserved, with zero impact on production line layout.
The side-mounted control panel enables rapid adjustments, reducing operation time.
Maintenance and cleaning are performed entirely from the outside, causing zero disruption to indoor production activities.
5.3. Economic Impact
Eliminated the need and cost of expanding the factory building just to house the equipment.
Reduced electricity costs by 40% thanks to DeAir.RE-1200's advanced Heat-Pump technology.

📊 INDOOR VS. OUTDOOR (CANOPY) INSTALLATION COMPARISON
Q1: Is the outdoor machine durable? Will it be affected by weather?
Absolutely durable. DeAir designs and installs a dedicated metal canopy to protect the unit from direct rain and sun. Furthermore, the DeAir.RE-1200 casing features high-quality powder coating with excellent corrosion resistance, ensuring a long operational lifespan.
Q2: Does the ducting system reduce dehumidification efficiency?
No, provided it is engineered to standard. DeAir engineers precisely calculate the optimal duct diameter and length, using smooth materials (like silver flexible duct or galvanized steel) to minimize pressure loss and ensure maximum airflow efficiency.
Q3: What is the maximum recommended duct length?
For optimal performance, the total combined length of the supply and return ducts should ideally be kept under 5 meters. If a longer distance is required, DeAir will advise on solutions such as inline booster fans or capacity adjustments.
Q4: Is the side-mounted control panel difficult to operate?
On the contrary, it is highly convenient. Placing the panel on the side allows operators to easily view the display and press buttons without being obstructed by the machine's main casing or the ductwork, which is especially useful in tight spaces.
Q5: Does DeAir design the canopy and ducting system?
Yes. DeAir provides a complete "turnkey" solution, including site survey, canopy design, ducting calculation, and full installation, ensuring a seamless, aesthetically pleasing, and highly efficient technical setup.
