Centrifuges for pharma and chemicals

Centrifuges are indispensable in industrial separation processes. Whether it’s separating solids from liquids, concentrating suspensions, or optimizing yields—the right centrifuge determines quality, speed, and cost savings.

Riera Nadeu has built up seven decades of expertise in designing industrial centrifuges for the pharmaceutical, chemical, food, biotech, and oil and gas sectors. Their RINA series are not just machines; they are engineering masterpieces that deliver scalability, automation, and process reliability; they are engineering designs that ensure scalability, automation, and process reliability.

Why the right centrifuge is crucial

Many companies still use outdated or suboptimal separation technology. This costs time, energy, and money—especially as production volumes increase.

The consequences:

• Slow throughput leads to production bottlenecks
• Poor separation quality results in reprocessing
• High energy costs due to inefficient rotation
• Manual adjustments require labor

Riera Nadeu centrifuges address this by:

• Automated processes that eliminate human error
• High centrifugal force (up to 15,000 G) for faster, more effective separation
• Robust construction for 24/7 operation
• Custom solutions tailored to your process chemistry

Step by step: implementation

1. Process Evaluatio

Riera Nadeu analyzes your current process: particle size, density, viscosity, and desired purity.

2. Machine selection & sizing

Based on volume, throughput, and quality requirements, you select the appropriate RINA series.

3. Test Phase

Many customers start with a small unit, test the separation process, and optimize parameters.

4. Scaling up & integration

Once validated, you move to production scale. Riera Nadeu assists with integration into existing lines.

5. Training & Support

Operator’s manual, on-site training, technical support—all included.

Costs & ROI

Yes, a Riera Nadeu centrifuge is an investment. But consider the total cost of ownership:

• Energy savings: Efficient separation = lower electricity bills
• Less reprocessing: Better separation the first time = less waste
• Increased throughput: More production per hour
• Labor savings: Automation = less manual labor
• Lifespan: 10–15+ years of reliable operation

For most industries, a Riera Nadeu centrifuge pays for itself in 2–4 years. After that, it’s pure profit.
