The Watertek 650L Hot Water Van Pack is a high-performance, fully integrated cleaning system designed for professional exterior cleaning specialists. Built in the UK and engineered with durability and efficiency in mind, it delivers powerful hot water pressure washing in a compact, space-saving stainless steel frame.

This model, the A4A000, combines the reliable Vanguard 18HP electric start V-Twin engine with a MA25-240 Mazzoni boiler and MM21250 low-speed Italian pump, producing 22 litres per minute at 250 Bar. The system includes a 650L integrated water tank and both high- and low-pressure 50m reels mounted on corrosion-resistant Watertek Pro stainless steel frames.

The ProFlame boiler unit is powered directly by the engine’s high-output alternator, requiring no external electricity, generators, or solar—allowing full independence and reduced downtime. Set-up is fast and hassle-free with Watertek’s rapid-deploy Pro Reels.
