Hot water makes the difference

Efficient high-pressure cleaning. Even more efficient with hot water. Compared to unpressurised cleaning procedures, Kärcher high-pressure cleaners offer impressive advantages in terms of economy, cleaning results and environmental impact. HDS hot water high-pressure cleaners enhance these advantages considerably when cleaning stubborn dirt. Kärcher HDS machines are usually the best solution for oils, grease and proteins – especially when these are encrusted.

Benefits of hot water high-pressure cleaners

A clear advantage with hot water.

Hot water high-pressure cleaners can raise the water temperature from around 12°C to as much as 155°C. This allows a reduction of the working pressure, cleaning time and the amount of detergent required. Cleaning with hot water therefore offers numerous options for optimising the cleaning process, as well as impressive advantages.

Better cleaning result

Hot water softens congealed oil and grease and significantly improves emulsification, making it very easy remove. In the food industry, proteins and grease can be loosened extremely effectively with hot water.

Better results

Reduced cleaning agent consumption

Grease, oil, resin, etc. can usually be removed with just hot water, so significantly less detergent can be used or detergent can be omitted entirely. In addition to cost savings, this protects the environment and conserves resources.

Shorter drying time

Surfaces cleaned with hot water dry faster thanks to the heat and are thus ready for subsequent processing or further use faster.

Improved hygiene

A significant reduction in germs can be demonstrated after cleaning with hot water. For many hygiene requirements, this germ reduction method without disinfectant is completely sufficient.

Shorter working time

Hot water results in faster dirt loosening and thus significant time savings of up to 35%. This means that a wide range of cleaning tasks can be carried out efficiently and cost-effectively.

Shorter working time

A clear conclusion: HD versus HDS cost comparison.

The cost of purchasing and maintaining a hot water high-pressure cleaner is initially somewhat higher due to the additional burner and related energy consumption. Using hot water offers a time saving of up to 35% with improved cleaning results. In addition, an HDS machine usually eliminates detergent expenses.

Higher temperature for better results.

Heat energy is an important factor in the cleaning process. Heat accelerates chemical processes; every 10°C increase in temperature doubles the reaction speed. Raising the temperature by 20°C increases the reaction speed fourfold. Oil, grease and soot are dislodged more quickly and can be removed more easily. The emulsion of oil and grease in water is accelerated. A heated surface also dries more quickly. In practice, higher water temperatures can reduce cleaning times by up to 35% – with significantly better results. By reducing the water volume, a steam temperature as high as 155°C can also be achieved. The combination of mineral-free steam and pressure can loosen even the most stubborn dirt. This ensures high cleaning performance, even without chemical additives. The steam stage is perfect for removing bitumen coatings, paint coatings in general, soot deposits, lichens and algae.
