Digital probe that records the temperature of coated chippings before spreading. UK surface dressing specifications require readings within a defined range for adhesion.

Portable logger clipped to the aggregate conveyor. Records chipping temperature to confirm compliance with Clause 922 surface-dressing specs.

Directs high‑velocity air from the sweeper fan to dislodge curbside debris.

Device removing moisture from the onboard air system before it reaches valves or brakes. Prevents corrosion and ice formation during winter sweeping operations.

Sheet of air shielding nozzle intake from splash-in water and fines.

Baffle reducing intake noise and debris ingestion.

Protective mesh fitted at the sweeper’s main intake to prevent large debris entering the fan housing. It reduces the risk of impeller damage and costly downtime.

Target ratio of binder volume to aggregate coverage.

Narrow jet of air used ahead of suction to lift fine dust from pores.

Mechanical feeder distributing coated chippings evenly across the spray width. Prevents clumping and ensures a uniform road texture in surface dressing works.
