Client: Binh Minh Textile Co., Ltd., Dong Nai Province, Vietnam
Industry: Textile Manufacturing – Factory Ventilation & Heat Extraction
Product used: YISA Heavy‑Duty Industrial Wall Exhaust Fans (1.5kW, 50 units)
Binh Minh Textile operates a large, single‑story weaving factory (4,500 m²) with over 200 looms. The looms generate significant heat, and the factory’s natural ventilation was inadequate. During the hot season (March–May), indoor temperatures reached 42–45°C (108–113°F), with high humidity and poor air circulation.
The consequences:
Workers suffered from heat exhaustion, leading to 20% higher absenteeism
Fabric quality degraded due to inconsistent humidity
12 old axial fans (domestic grade) failed frequently – motor burnouts every 3–4 months
Electricity cost for ventilation was high because fans ran continuously with low efficiency
The management needed:
Industrial‑grade fans capable of 24/7 operation in hot, dusty environment
Higher airflow to push hot air out and bring fresh air in
Lower maintenance – no frequent motor repairs
Energy efficiency to reduce monthly utility bills
After an on‑site airflow assessment, our engineering team recommended 50 units of YISA heavy‑duty wall exhaust fans, model YEF‑W1500, with the following features:
| Specification | Value |
|---|---|
| Blade diameter | 1,500 mm (50 inches) |
| Motor power | 1.5 kW, 380V/50Hz (adapted to Vietnam grid) |
| Airflow | 42,000 m³/h per fan |
| Noise level | ≤ 75 dB at 3m |
| Protection | IP55 (dust‑ and water‑jet protected) |
| Frame material | Heavy‑gauge galvanized steel |
| Blades | Aluminium alloy, dynamically balanced |
| Bearings | Sealed, self‑lubricating (maintenance‑free for 20,000 hours) |
Installation layout:
20 fans mounted on the long side as exhaust, 30 fans on opposite side as intake (with louvers and insect screens). The system creates a cross‑ventilation pattern covering the entire factory.
Additional support from YISA:
Provided electrical wiring diagram for grouped fan control (3 zones)
Supplied spare belts and thermal overload relays with the order
Remote troubleshooting via video call during commissioning
Three months after installation, Binh Minh Textile recorded the following improvements:
| Metric | Before (Old Fans) | After (YISA Fans) |
|---|---|---|
| Average indoor temperature (hot season) | 43°C | 32°C (↓ 11°C) |
| Worker absenteeism (heat‑related) | 18–22% | 6% (↓ 70%) |
| Fabric defect rate due to humidity | 4.5% | 1.2% |
| Monthly electricity cost (ventilation) | $1,850 | $1,120 (↓ 39%) |
| Fan failure incidents (6 months) | 7 failures | 0 |
“The difference is night and day. Our workers are actually comfortable enough to stay productive through the afternoon. The YISA fans run all shift without overheating or making too much noise. And the electricity savings alone will pay for the investment in less than one year. We are planning to order another 30 fans for our dyeing facility.”
– Mr. Tran Van H., Factory Director, Binh Minh Textile
