How RAETTS Explorer Blowers Helped a Taiwan PCB Factory Achieve 55% Energy Savings

In today’s competitive electronics industry, energy efficiency is not only about lowering operational costs—it is also about sustainability, carbon reduction, and staying ahead of the competition. Printed Circuit Board (PCB) manufacturers, in particular, face constant challenges in their production lines where large amounts of energy are consumed during electroplating and drying processes.

This case study highlights how RAETTS’ Explorer High-Speed Blowers transformed the production efficiency of a leading PCB factory in Taiwan, delivering dramatic results that exceeded expectations.

Background: High Energy Consumption with Traditional Ring Blowers

The client, a well-established PCB manufacturer in Taiwan, operated 6 electroplating lines and 2 drying lines. Their airflow needs were previously met using 12 traditional ring blowers, with a total installed power of 123.5 kW.

While ring blowers are common in the PCB industry, they come with serious limitations:

• High energy consumption: Operating close to full load most of the time.

• Limited efficiency: Difficult to adjust airflow for specific process demands.

• Rising operational costs: Electricity expenses continued to climb year after year.

• Sustainability concerns: Excessive power usage led to a high carbon footprint.

The factory’s management was actively seeking a solution that would reduce energy bills without compromising production quality, while also aligning with their long-term sustainability goals.

The RAETTS Retrofit Solution

After a thorough technical evaluation, RAETTS proposed replacing the existing 12 ring blowers with 7 units of RAETTS Explorer High-Speed Blowers.

What makes the Explorer blower different?

• PMSM (Permanent Magnet Synchronous Motor): High efficiency with reduced energy losses.

• Built-in Variable Frequency Drive (VFD): Precise airflow control, matching the actual process needs.

• 3D Mixed-Flow Impeller: Optimized aerodynamic design for stronger and more stable airflow.

• SKF Bearings: Reliability and extended service life with low maintenance requirements.

• Compact and versatile: Easy integration into existing plating and drying lines.

The retrofitting process was carried out smoothly, with minimal disruption to production.

Results: Remarkable Energy and Cost Savings

The impact of the RAETTS solution was immediate and significant.

• Total installed power reduced from 123.5 kW to 68.5 kW

• Overall efficiency improved by 55%

• Annual electricity cost savings: USD 64,449

• Carbon emission reduction: 237,600 kg CO₂ per year

• Payback period: just 4 months

One of the key findings was that, while the original ring blowers were operating at nearly full load (thus consuming close to their rated power), the RAETTS Explorer blowers operated below their rated power, achieving even greater energy savings and reduced carbon emissions.

Why This Case Matters

This project demonstrates that investing in modern high-speed blower technology is not only about replacing outdated equipment—it’s about transforming the way a factory operates. The Explorer blower delivered:

• Lower energy bills without compromising production capacity.

• Faster ROI, with investment payback achieved in less than half a year.

• Improved sustainability, helping the factory move closer to its ESG goals.

• Reliable performance, ensuring consistent aeration and drying results.

For industries like PCB manufacturing, where plating and drying are energy-intensive, the RAETTS Explorer blower is not just an upgrade. It is a necessity for companies aiming to remain competitive, cost-efficient, and environmentally responsible.

Conclusion

The Taiwan PCB factory’s retrofit project proves one simple truth: 55% energy savings and a 4-month ROI are too significant to ignore. With RAETTS Explorer blowers, manufacturers can achieve operational excellence while contributing to global sustainability efforts.

Whether it’s PCB production, packaging lines, or other industrial drying and aeration applications, RAETTS continues to deliver solutions that combine innovation, efficiency, and reliability.

If your factory is still relying on outdated ring blowers, maybe it’s time to ask: How much energy and money are you losing every year?
