Spray Coating System

Hobart/ Tafa Technologies HP/HVOF System, Model: JP-5000. 

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.
