Cleaning challenges
What do you want to tackle first with pressure washing?
Factory yards, construction equipment and vehicle points can be dispersed, making fixed power inconvenient.
Oily sludge, deposits, residual sand and loose rust need task-specific jet assessment.
Do not place a petrol engine indoors or in partly enclosed spaces where exhaust can accumulate. Petrochemical hazardous areas need verification; ventilation does not establish explosion protection.
Site conditions, configuration and selection
Where is the cleaning taking place, and what are the conditions? Determine the configuration together.
The following is a selection reference, which does not replace original technical data, on-site verification, and trial washing.
01 Exterior of Engineering Equipment
