Thermometer on return line to verify tank temperature.

Electronic controller that maintains binder within the specified 160 – 180 °C range. Prevents overheating and ensures correct viscosity during spraying.

Applies glass beads onto hot thermoplastic/paint for retroreflectivity.

Battery-powered logger recording binder temperature throughout a shift. Provides traceable evidence for quality-assurance audits.

Valve adjusting the quantity of reflective beads delivered to the spray gun. Ensures consistent retro-reflectivity on road markings.

Automatic temperature control preventing overheating of bitumen in tank.

Sensor monitoring glass bead delivery rate.

Shaft transmitting power from the PTO to the binder pump. Regular greasing prevents spline wear and vibration issues.

Setting bead flow per metre in sync with line speed.

Filter fitted to the binder return circuit preventing solid contamination. Maintains clean recirculation and reduces nozzle blockages.
