Buyer guidance
Drive-through Bus Wash TH-350 is a commercial vehicle wash option for fleets that need larger vehicle clearances and repeatable cleaning routines.
Rated for 40–80 buses per hour, with typical water usage of around 150 L per vehicle and power demand of about 12 kW, and maximum vehicle heights of 3.5 m (TH-350) or 4.2 m (TH-450)—covering most city buses and coaches.
Automatic and manual modes with Mitsubishi PLC control let operators choose between water-only and chemical wash programs, balancing cleaning power with operating cost and site policies.
A hot-zinc treated structure with baked finish and imported wear-resistant brush strips are designed for long life in high-throughput depots, reducing downtime and replacement frequency.
