How a DYNAJET water-jetting units handles freezing conditions in Sweden

Even in deep winter, high-pressure cleaning has to deliver consistent results. In Malmö, southern Sweden, a DYNAJET high-pressure water-jetting system was used during an application demonstration in freezing temperatures, persistent snowfall and challenging outdoor conditions. The example shows why mobile equipment must remain dependable when weather and working conditions are far from ideal.

The task was graffiti removal, and the machine completed it quickly with hot water, a flat-jet nozzle in the double-spray lance and a working pressure of up to 350 bar. Before use, antifreeze based on monoethylene glycol was added to the water tank to protect the system and support safe operation in cold weather. This made it possible to work reliably without compromising the equipment.

For professional operators, the practical message is clear: a mobile cold- and hot-water high-pressure cleaner must do more than perform in good conditions. It should remain ready for action when temperature, moisture and working environment become more demanding. That is especially important for training situations, municipal cleaning tasks and other applications where cleaning results need to be achieved on site and without delay.

The Swedish demonstration underlines the value of dependable equipment in real-world use. Whether the goal is graffiti removal or other demanding cleaning work, operators benefit from a machine that can be deployed safely, handled efficiently and used with confidence in harsh weather.
