In industrial cleaning, companies face a choice between various processes. Two proven methods are cleaning with hot-water low-pressure systems from ph-cleantec and hot-steam cleaning. Both processes offer specific benefits, depending on the respective requirements and areas of application.

Low-pressure hot-water cleaning from ph-cleantec
The ph-cleantec cleaning system combines high temperatures of up to 95 °C with low pressure (3 – 7.5 or 3 – 14 bar). The method is particularly suitable for removing greasy and oily contamination on sensitive and complex surfaces.
Benefits:
- Efficient cleaning: The high temperature loosens greases and oils effectively, while the low pressure gently removes the contamination. Since work is done in the liquid range, contamination is transported away without any problem and thoroughly. Cleaning generally requires significantly less effort than alternative methods.
- Resource-saving: The water consumption is only 1.8 to 2.8 litres per minute, and the water is usually reused in a circuit. Chemicals are needed at most in the form of an alkaline cleaner in low concentration (1–3%). That saves expensive chemicals.
- Environmentally friendly: Through the low use of water and chemicals and the recycling, the environmental impact is minimised. That saves expensive disposal costs.
- Occupational safety: Since no hazardous chemicals are used and at most minimal droplet clouds arise, there are practically no health risks for the employees.
- Economical: Through the fast cleaning and the minimal resource consumption, the method is particularly cost-efficient.
Areas of application:
- Parts cleaning of small to large components
- Especially complex surfaces and greasy and oily contamination
- Cleaning of machine tools with their own cooling lubricant, or whole systems in machining, in the transport sector and in the food industry
Hot-steam cleaner
Hot-steam cleaning uses saturated water vapour, generated at temperatures of over 100 °C and high pressure. The steam penetrates into pores and crevices and loosens contamination through condensation and the energy released in the process.
Benefits:
- Deep cleaning: The steam reaches hard-to-reach spots, loosens contamination there, and removes bacteria and fungi.
- Chemical-free: In many cases the use of cleaning agents can be dispensed with.
- Fast drying: Since little moisture remains, the cleaned surfaces dry quickly.
Areas of application:
- Cleaning in the food industry
- Disinfection in medical facilities
- Removal of light contamination on smooth surfaces

Conclusion: when is which method better?
ph-cleantec is particularly suitable when:
- Sensitive components have to be cleaned
- An environmentally friendly and resource-saving method is desired
- Cleaning is to be carried out with minimal use of chemicals
- A pragmatic and at the same time economical solution is sought
Hot-steam cleaner are advantageous when:
- A deep-acting disinfection is required
- Light contamination on smooth surfaces is to be removed
For many industrial applications, low-pressure hot-water cleaning from ph-cleantec offers an efficient and thorough, and at the same time environmentally friendly and cost-effective, alternative to hot-steam cleaning. However, the choice of the suitable process depends on the specific requirements and circumstances.
