Praxair TAFA JP-5000 System

Astro Alloys offers Praxair’s original 1992 liquid-fueled HP/HVOF system, the Model JP-5000. The Praxair TAFA JP 5000 console is a high-pressure HVOF system that remains unparalleled in coating consistency and reproducibility. The semi-automatic, rotometer-controlled console has proven itself to be unequaled in coating reproducibility and robustness for long-term use. It features a semi-automatic rotometer-controlled console that controls all operating parameters including cooling water, powder, carrier gas, oxygen, and fuel flows.

By using kerosene instead of gaseous, the Model JP-5000 provides superior HVOF coating quality by combining higher combustion flame temperatures and pressures, improved powder injection, better barrel powder mixing, and higher particle velocities.  In addition to outstanding coating quality, the JP-5000 system delivers a significant productivity advantage, with spray rates up to three times higher than conventional HVOF systems. The ability to apply more coating in less time reduces coating costs and increases the range of competitive coating solutions. As the JP-5000 system runs on kerosene, it is safer and more economical to run in comparison to more volatile gases such as hydrogen, natural gas, or propylene.

JP-5000 Console Features

Praxair JP-500 HVOF SystemModel Features of the Praxair TAFA JP-5000 Console include:

  • CE compliant
  • Digital pressure displays
  • Dual, radial, low-pressure powder injection
  • Less sensitive to cooling water temperature
  • Less sensitive to powder particle size than other HVOF systems
  • Longer, less-sensitive spray distance
  • Monitored combustion and back pressures
  • Superior coating integrity and uniformity
  • Up to two powder feeder on/off control
  • The system includes multiple, interchangeable, gun options: Model 5220 & Model 8200

TAFA Model 5220 Gun

The TAFA Model 5220 is a kerosene-fueled HP/HVOF gun, also referred to as a torch, that is used with the TAFA JP-5000 console to achieve extremely high coating densities. The unique design of this gun allows it to produce particle velocities of 3,300 to 3,900 fps, which is significantly higher than any other gaseous-fueled HVOF device on the market today. In addition to the outstanding coating quality, the Model 5220 gun delivers spray rates up to two times higher than gaseous-fueled HVOF systems. This superior spray rate and productivity place the JP-5000® and JP-8000™ HP/HVOF® systems in a unique category of HVOF equipment: High-Pressure HVOF. It also permits the job to be done with less equipment, while improving the turnaround time with reduced maintenance and labor costs.

TAFA Model 5220 Spray GunModel 5220 Torch features:

  • Efficient combustion and particle heating
  • Efficient gun cooling
  • Multiple gun configurations with multiple barrel lengths
  • Radial, low-pressure powder injection
  • Thick coating capability
  • 3-way powder splitting
