Built for maximum service life in such industries as wood, paper/pulp, gypsum, veneer, biomass, chemical, waste, and energy/power plants, industrial air dryers and air preheaters come in plain and finned tube system options. Compact, aerodynamic elliptical tube version offers ~3–10X less hydraulic friction than round tubes, minimum soiling, and corrosion protection. Other distinguishing features include minimized pressure loss and noise as well as optimized thermal transmittance.
