7. What is ‘third generation’ coating technology
Nordson examined the three disciplines of powder coating:
The Heart / HDLV Pump
Powder Transport
Precision Dispensing
Powder Circulation
To improve each area we developed our ‘dense phase’ product family named Prodigy® HDLV®

8. Prodigy® HDLV® Technology
What is ‘Dense Phase’ Equipment ?
The Heart / HDLV Pump
HDLV = High Density powder, Low Velocity air
Powder delivery hose has a high concentration of powder, very little air.
Traditional venturi pumps use hi-velocity air – HDLV pumps meter powder to the gun using less air to propel.
HDLV is 4 times slower – softer spray.

10. Prodigy® HDLV® Technology
What Does It Do For The User ?
Provides process control
Less overspray
Higher transfer efficiency
Lower velocity powder = higher useful electrostatic force
Paints faraday areas and corners easier
Higher powder output with better charging

11. Prodigy® HDLV® Technology
The Heart / HDLV Pump
At the centre of dense phase technology is the HDLV (High Density Low Velocity) pump.
It resembles a human heart in that it consists of two side by side pumps each with an upper and lower chamber working together to provide precise, carefully synchronized powder transport.

12. Prodigy® HDLV® Powder Transport
How Does It Work ?

13. Traditional Venturi Pumps vs Dense Phase Pumps
The old and the new
Venturi Pump
Flow rate controlled by combination of Flow + Atomizing air flow rates
Lots of air goes out to the gun
Use 11mm or 12.5mm ID powder hose
Dense Phase Pump
Flow rate controlled by cycle rate & suction duration
Very little air goes out to the gun
0.5 to 1.2 scfm of conveyance air
Use 6mm ID powder tubing

14. Traditional Venturi Pumps vs Dense Phase Pumps
Venturi pumps are non-linear in output
Dosing air

15. Traditional Venturi Pumps vs Dense Phase Pumps
Dense phase pumps achieve linear output

16. Traditional Venturi Pumps vs Dense Phase Pumps
Lack of wear components means consistency over time

17. Traditional Venturi Pumps vs Dense Phase Pumps
Reduced total air consumption compared to venturi pumps

18. Prodigy® HDLV® Powder Transport
Dense Phase Pump Without Moving Parts
Self cleaning / colour changing
Constant powder output over time
30 second colour change
High volume – low air consumption
6mm ID powder hose

19. Prodigy® HDLV® Precision Dispensing
New gun to spray dense phase
Unique profile prevents powder build up on the gun
Automatic gun with straight through powder path, optimised for dense phase dispensing and quick colour change

20. Prodigy® HDLV® Precision Dispensing
New gun to spray dense phase
Voltage multiplier positioned at the back of the gun – so it operates outside of the booth, reducing gun flex and grounding issues

27. Prodigy® HDLV® Technology
Third Generation Coating Equipment
3 Steps To Process Control
Transport process control is achieved by eliminating venturi wear from the equation and ensuring that air inputs to the pump are monitored and driven by a closed loop control system, dynamically compensating for fluctuations in factory air supply

28. Prodigy® HDLV® Technology
Third Generation Coating Equipment
3 Steps To Process Control
Dispensing process control is achieved by conserving all application parameters in the control system, and by spraying through a soft spray gun suited to dense phase applications. This ensures the same results are achieved day after day

29. Prodigy® HDLV® Technology
Third Generation Coating Equipment
3 Steps To Process Control
Recycle process control is achieved by reduced compressed air used to propel the powder, producing more efficient recycling, sieving and bulk feeding

31. Prodigy® HDLV® Technology
Process Improvement
When dense phase coating is compared process control can be clearly displayed

32. Prodigy® HDLV® Technology
Process Improvement
Once process control is accomplished, improvement is achievable by using the control system and ‘digital’ nature of the technology to % adjust the gun outputs (linear output)
