Heater on nozzle block to prevent cooling at tips.

A nozzle calibration chart is a reference tool used to match nozzle size, operating pressure, and flow rate to achieve accurate application output. It reduces trial-and-error and supports specification compliance. Charts are used alongside known material properties and vehicle speed to set correct outputs. Accurate calibration helps reduce waste and improve consistency. Calibration is a…

Table matching nozzle size/pressure to target application rates.

Flexible rod for clearing partially blocked spray nozzles. Keeps spray pattern consistent without dismantling the entire bar.

Map showing which nozzles form each zone.

Hand wheel allowing fine adjustment of nozzle height. Ensures correct overlap and film thickness when spraying binder.

Tool to set spray nozzle height above road for correct overlap.

Spray pattern test using paper/foil laid across the spray width.

Manual valve isolating a section of the spray bar during maintenance. Allows single-nozzle testing without draining the system.

Flexible skirt sealing the suction nozzle to the road surface.
