In the world of powder coating, efficiency and cost savings are paramount. Whether you're a small business or a large-scale manufacturer, finding ways to reduce material waste, improve productivity, and maintain consistent quality is essential for staying competitive. This is where Nordson’s HDLV (High Density, Low Velocity) technology comes in—a game-changing innovation that has redefined the powder coating process.

Nordson’s HDLV technology, featured in systems like the Encore HD, offers unmatched precision, reduced material consumption, and faster colour changes. In this blog, we’ll explore how this revolutionary technology can save you time and costs while delivering superior results.

What is HDLV Technology?

HDLV stands for High Density, Low Velocity—a dense-phase powder transport system that moves more powder with significantly less air compared to traditional venturi systems. Unlike conventional ejector-pump systems that rely on high air volumes to deliver powder, HDLV technology separates the powder and air streams. This allows for precise control of both the powder output and spray velocity.

Key Features of HDLV Technology

• Soft Spray Patterns: Provides gentle yet efficient powder application, ideal for complex shapes and recessed areas.
• Independent Control: Enables fine-tuning of powder output and spray velocity for optimal application efficiency.
• Reduced Air Usage: Minimizes turbulence and wear on internal components, extending equipment longevity.

How HDLV Technology Saves Time

1. Faster Colour Changes

Traditional venturi systems often require lengthy cleaning processes during colour changes due to excessive powder/air velocity causing impact fusion inside hoses and nozzles. HDLV systems eliminate this issue with integrated purge features that enable ultra-fast, contamination-free colour changes. Manufacturers report colour change times reduced to mere seconds, significantly minimizing downtime.

2. Consistent Performance Over Time

Unlike venturi systems that degrade due to wear on internal components like venturis, HDLV pumps maintain stable performance for thousands of hours without adjustments or part replacements. This consistency eliminates the need for frequent recalibrations and ensures reliable coating quality across production runs.

3. Simplified Maintenance

With fewer moving parts and reduced wear on components, HDLV systems require minimal maintenance. For example, some users report over 4,000 hours of maintenance-free operation with Nordson Encore HD pumps—saving both time and labour costs.

How HDLV Technology Reduces Costs

1. Powder Savings

HDLV systems deliver a high concentration of powder with minimal air volume, resulting in higher transfer efficiency and reduced material waste. Many manufacturers report powder savings of up to 30% compared to traditional venturi systems. This reduction in material usage directly impacts your bottom line.

2. Energy Efficiency

By using less air to transport powder, HDLV systems consume less energy overall. This not only reduces operating costs but also supports eco-friendly practices by lowering your carbon footprint.

3. Reduced Labour Costs

The automation capabilities of HDLV systems—such as automatic purging during colour changes—reduce the need for manual intervention. This frees up your workforce for other tasks and minimizes labour expenses.
