Pressure washer Trailer

New 1000L Mine Spec Pressure Washer Trailer with Hot Box
Heavy-duty hot water pressure washer trailer built for mining, civil, fleet and machinery washdown

This is a serious 1000 litre pressure washer trailer with diesel-fired hot box, built by Welding Solutions for industrial, civil and mine site use.

Powered by a Yanmar 10HP diesel pressure washer and fitted with a Spitwater diesel-fired hot box, this unit is ideal for cleaning trucks, earthmoving equipment, plant, machinery, workshops, yards and site vehicles where cold water just does not cut it.

Hot water makes a big difference when dealing with grease, oil, mud and heavy site grime. If you need a mobile washdown unit that is tough, practical and built for commercial use, this trailer is a strong option.

Why This Unit Stands Out

This is not a light-duty hardware-store pressure washer on a trailer.

It is a commercial trailer package built for operators who need reliability, safety and practical site use. The trailer includes a 1000 litre water tank, heavy-duty tandem axle chassis, diesel engine pressure washer, hot box, hose reel, toolbox, safety equipment and mine-spec inclusions.

The hot box heats water up to 95°C, helping break down grease, oil and grime much faster than cold water washing. That means faster cleaning times, better results and less time wasted trying to clean dirty machinery.
