What spray capacity, nozzle type, and pressure control should be checked when hiring a bitumen emulsion sprayer?

Ensure the sprayer can deliver required application rates at planned travel speeds with stable pressure. Nozzles must be suitable for emulsions and sized for uniform fan patterns. Pressure control should be smooth to avoid pulsing. Check filtration, recirculation, and cleaning provisions. Calibration capability and operator experience matter as much as nominal capacity when hiring equipment.
