The High pressure cleaner label of EUnited Cleaning is a seal of approval that the highly efficient burner of the tested oil-heated stationary or quasi-stationary high pressure cleaner is meeting extreme high safety requirements in terms of thermal exhaust loss q_A, CO emissions, and dust emissions. These parameters have to be monitored in order to protect the operator from any danger emitted by the exhaust of the burner built in the high-pressure cleaner. High pressure cleaners are applied for the removal of dirt in various areas, from cleaning vehicles to outdoor equipment. If the equipment to be cleaned is heavily soiled, with e.g. grease or different kinds of oil residues, an oil-heated stationary or quasi-stationary high pressure cleaner is of advantage due to the higher solubility of hot water in contrast to cold water.
