Spray Painting with Heated Nitrogen
Liquid Material application using spray gun technology has relied on compressed air since the early 1900s.
The presence of moisture in compressed air has always been a challenge during liquid and powder applications. Inline filtration and refrigerated drying do remove some of the moisture created during the condensation process.
Point of use compressed air filters further assist in the removal of moisture, but with minimal benefits to the application of spray paint. Moisture in the compressed air lines affects the quality of application when spraying paint or other liquids that do not react well with moisture. When spraying paint with compressed air, you are atomizing the paint with multiple gases that make up our atmosphere. The ideal requirement for a propellent should be one without moisture present. Hence, the use of Nitrogen. Nitrogen is the most abundant gas in our atmosphere and obviously, the same in compressed air.
The inert qualities of Nitrogen allow the addition of heat without any effects, but the benefits of heated Nitrogen raise the quality and efficiency of spray paint application. The process of using heated nitrogen through the separation of oxygen and hydrogen from compressed air results in the cleanest, dry medium available for spray applications. The addition of heat to the nitrogen further enhances efficiency and productivity in the promotion of the curing/drying time of the liquid being applied.
The atomisation process using a single gas (nitrogen) is far more efficient than the atomisation of paint with multiple gasses in compressed air. Atomisation can now occur at lower pressures, thereby minimising overspray and wasted material with significantly fewer VOCs being exhausted into the atmosphere, which subsequently increases the lifespan of spray booth exhaust filters and most importantly does not harm the environment.
Use of this technology results in benefits in material savings, improved cycle times (due to faster curing), and a higher quality finish. The spray painting process requires large volumes of nitrogen and can be addressed with an in-house “nitrogen on-demand” generator solution that eliminates the need for high-pressure tanks and adherence to hazardous requirements.
