Optimal Header Geometry & Spacing
Calculates exact nozzle pitch, mounting height, and nozzle count required to deliver target fluid thickness across any target web or conveyor width.
Pitch Solver · Height Optimization
Header Optimization Architecture
Eliminate guesswork from spray manifold design.
This software works best with nozzle distribution data captured directly by the SprayScan mPT.
A single spray pattern captured with the mPT can be loaded into VOA, and you receive an optimal header design in under 5 minutes. The software models overlapping liquid distribution curves across wide continuous webs, conveyor belts, and strip processing lines, letting you pinpoint the exact spacing that minimizes Coefficient of Variation (CV%).

What It Does
Precision Header & Overlap Engineering
For precision coating and spraying operations where coverage uniformity directly impacts product quality and material costs.
Coefficient of Variation (CV%) Modeling
Quantifies spray distribution uniformity mathematically. Detects light stripes, dry streaks, and heavy overlap ridges before metal is cut or headers fabricated.
CV% Analysis · Eliminates Banding
Nozzle Wear & Degradation Impact
Simulate how tip erosion, orifice clogging, or pressure fluctuations degrade header overlap over time, empowering predictive maintenance cycles.
Wear Simulation · Life-Cycle Planning
Substantial Chemical & Material Savings
Eliminate excessive overlap margins and over-application buffers, cutting expensive liquid coating, lubricant, or active chemistry consumption by up to 15–30%.
15–30% Liquid Reduction · Rapid ROI
