Upgrade cooling performance without redesign. See how MEGA enabled PWM speed control on an existing EC12038 fan system to reduce noise and save development cost.
📌 Case Study: Smart PWM Upgrade for EC12038 Fans — No System Redesign Required
How MEGA Cooling Solutions Helped Engineers Meet New Noise Requirements Faster
✅ Background: A New Requirement After Years of Operation
One of our long-term customers had successfully integrated our EC 12038 axial fans into their equipment years ago.
But recently, their end customers requested:
“Lower operating noise — especially in low-load conditions.”
However, the original system did not have PWM control capability. And after years of iteration and staff turnover, re-developing the cooling system would mean:
Costly redesign and firmware changes
System re-certification
Longer development and approval cycles
Increased risk and engineering workload
For many OEMs, this is a critical business challenge: 👉 New performance requirements vs. 👉 Legacy system limitations
✅ MEGA’s Role: Not Just a Fan Supplier — A Technical Partner
Instead of pushing them to purchase an entirely new fan model, we proposed a simple but powerful upgrade solution:
🔧 Add an external PWM controller to enable 0%–100% fully adjustable fan speed
PWM Controller
This allowed them to:
✅ Reduce noise at low temperatures ✅ Boost airflow during heat spikes ✅ Achieve energy savings through variable control ✅ Keep all existing hardware and software untouched
✅ Engineering Proof: Real-Time PWM Demo
During validation testing, we demonstrated:
Full 0–100% duty cycle adjustment
Smooth speed changes
Immediate performance responsiveness
Compliance with new acoustics targets
📌 This proved to their stakeholders that the upgrade was:
✔ Practical ✔ Reliable ✔ Scalable across multiple product lines
