What specifications and capacities should be considered when sourcing bitumen emulsion sprayers in India?

Focus on calibrated spray performance and robustness rather than tank size alone. Key specs include pump type that avoids excessive shear, stable pressure control across the bar, nozzle type and spacing, transverse distribution performance, flow metering, and recirculation that keeps emulsion uniform. Capacity should match daily consumption and logistics, with insulated tank options if needed. Include cleaning and flushing design, filter strainers, and anti drip valves. For compliance, ensure the sprayer can meet the application rate accuracy required by local road authority specs and can handle the viscosity range of your target grades without clogging.
