Why to RINSE from top to bottom?

  • Prevent recontamination
  • Minimize extra work
  • Be more efficient

Why to FOAM from bottom to top?

Detergent is allowed to work its way up as you progress. This method ensures that the cleaning agents

Foam Cleaning

Foam cleaning is a method used in various industries, including the food and beverage industry, for effective and efficient cleaning of surfaces, equipment, and hard-to-reach areas.

It involves the application of a foam cleaning solution that expands into a foam consistency, adheres to surfaces, and aids in the removal of soils and contaminants.

Foam cleaning is widely employed in the food and beverage industry, particularly in facilities where hygiene and sanitation are critical.

It offers efficient and versatile cleaning, reduces water consumption, and helps maintain high cleanliness standards.


Foam Cleaning Principles and Benefits.


Key Aspecsts of Foam Cleaning

Application Process

Foam cleaning involves the use of a mixing block (which is the heart of each cleaning station) that mix water, cleaning chemicals, and air to create a foam solution. Nilfisk FOOD Patented Corona technology air system injects air into the water stream at a higher speed, resulting in better mix of water, detergent and air. Thanks to bigger foam volumes with longer cling time, less detergent is required to do excellent cleaning job.

Foam is applied to the surfaces or equipment using a foam nozzle, The foam expands upon contact, adheres to the surfaces, and remains in place for an extended period, allowing the cleaning agents to work effectively.

Lower Water Consumption

Foam cleaning typically requires less water compared to traditional cleaning methods such as spraying or rinsing with liquid.

A typical Nilfisk FOOD foam nozzle uses 8L/min (2.1 gal/min) of water during the foaming process. During the rinsing process a typical rinse nozzle use 30L/min (7,9 gal/min).

This water-saving aspect makes foam cleaning an environmentally friendly option and contribute to cost savings in terms of water usage.

Enhanced Cleaning Efficiency

The foam consistency of the cleaning solution provides better coverage and longer contact time compared to liquid-based cleaning methods.

Foam clings to vertical and irregular surfaces, allowing the cleaning agents to penetrate and dissolve soils, fats, oils, and other contaminants effectively.

The extended contact time provided by the foa


Corona Technology

Patented Corona technology air system injects air into the water stream at a higher speed, resulting in better mix of water, detergent and air.

The results? Approx. 20% more foam, LONGER cling time, LESS detergent.

Versality and Adaptability

Foam cleaning can be utilized for various applications, including cleaning of production equipment, conveyors, walls, floors, and other hard surfaces. The foam can reach areas that are challenging to clean.

Optimized Pressure

During the entire cleaning process the Pre-Rinse and Rinse steps take approx 80% of the cleaning time and consume the most water.

Our patented technologies help to safe approx. 47% of water usage and reduce energy consumption.

The Patented Tornado Rinse nozzle bundles and aligns water stream while creating turbulences inside the nozzle, resulting in significant water savings, while increasing the rinsing impact by approx. 20%.

Water stream from the Tornado nozzle is flat and equally strong across the entire rinse pattern. Compared to a standard nozzle, the rinse impact is strongest in the middle of the nozzle, and loosing the strenghts on the sides. This improves the cleanign efficiency.

Optimizing water usage will result in reducing energy consumption used to heat up water, and in turn, indirectly help reduce greenhouse gas emissions and CO2 emissions.

Consuming less water will create less wastewater that need to be processed to make it safe again, thus it will also reduce energy and reduce the greenhouse gas emissions.

Pre-Rinse and Rinse steps takes approx. 80% of the cleaning time and consume the most water.

Nilfisk FOOD spent a lot of research on developing technologies to save water. Our patented technologies safe approx. 47% water, reduce energy consumption, reduce greenhouse gas emissions and CO2 emissions.
