Inspect, clean, and clear blockages in high-pressure spray nozzles, manifolds, and delivery lines to ensure uniform chemical application. Inspect and treat framework, tanks, and structural components for corrosion caused by harsh de-icing chemicals and winter road salts. Test and calibrate flow meters, pressure valves, and automated dosing controls to optimise fluid usage and system reliability. Provide reactive breakdown support during freezing weather to ensure de-icing equipment remains 100% operational.
