Low-pressure foam cleaning PHT

Modern low-pressure foam cleaning for the food industry: efficient, hygienic, sustainable

Maximum hygiene, minimal costs – with PHT’s modular low-pressure foam cleaning systems, cleaning in food processing plants becomes easier, more economical and more environmentally friendly.

Whether in meat processing, dairies or beverage bottling – hygienic cleanliness is essential. At the same time, requirements for efficiency, sustainability and cost-effectiveness are increasing. PHT’s low-pressure foam cleaning offers the optimal solution right here:
  • High cleaning performance at low pressure (5–25 bar)
  • Low consumption of water, chemicals and energy
  • Short rinsing times
  • Reduced aerosol formation – lower risk of recontamination
Thanks to innovative technology, PHT’s low-pressure foam cleaning offers maximum ease of use and maximum efficiency and has been impressing numerous companies in the food industry for years.

Key benefits at a glance

  • One system for all cleaning processes: from pre-cleaning and foam application to disinfection
  • NEXT technology – 3 chemicals via one outlet
  • Individually scalable: perfect adaptation to the operation and requirements
  • Compatible with acids and alkalis
  • Government-funded: BAFA grants for systems with energy-efficient IE5 motors

Flexible system solution – tailored to your operation

PHT cleaning systems are modular and can be precisely adapted to operational conditions:

1. Main station
The main station is a stationary solution with an integrated booster system – ideal for local cleaning areas.
Equipped with a rinse hose and accessories, all cleaning is conveniently carried out centrally here.



2. Booster system

The booster system increases the water pressure on the supply side and, via a piping system, supplies several cleaning stations with boosted water pressure. It is the optimal solution for larger food businesses with high water consumption and demanding hygiene standards. Typically, a booster system is installed centrally in the plant room.

PHT systems operate with frequency control, which means performance is automatically adjusted to current water demand. This minimizes energy consumption and wear. A powerful stainless-steel centrifugal pump ensures reliable, hygienically flawless water delivery – even under permanently high loads.
An integrated flow monitor continuously monitors the flow rate in the system. This allows the system to respond immediately to deviations and detect faults early – for maximum operational reliability and efficiency.

3. Satellite stations with NEXT-type injector block

The connected satellite stations are the heart of the modular solution. What’s special about PHT satellites: they are equipped with the innovative “NEXT” injector block and enable individual adjustment of foam, rinsing and cleaning processes. With just one movement, users switch between functions and can use up to three chemicals via a single outlet. This ensures maximum flexibility while maintaining the highest level of hygiene safety.

How low-pressure foam cleaning works

Step 1: Boosted water is fed through a nozzle
Step 2: Negative pressure draws the cleaning agent from the canister
Step 3: Compressed air is added and foams up the water-chemical mixture
Step 4: The foam is applied evenly to the surface
Step 5: After the contact time, post-rinsing or disinfection takes place
With one movement, you can switch between water, foam or disinfectant – intuitive, safe, fast. The nozzles can be swapped out flexibly, enabling precise adaptation to different cleaning requirements.

Clean sustainably with the PHT Green Button

While eco programs have long been standard in household appliances, this has not been the case for professional foam cleaning until now. PHT changed that – with the innovative PHT Green Button, which reduces energy consumption by up to 50% and water consumption by around 20%.

Reduce pressure in a targeted way – conserve resources

The Eco function makes it easy to reduce working pressure during cleaning by 10 bar at the push of a button – directly on the unit, without interrupting the process. Especially for intermediate and final rinsing, lower pressure is sufficient to achieve an optimal result. This not only saves resources, but also reduces costs and protects the equipment.

Efficiency that pays off

In Eco mode, the unit only needs 1.3 kWh instead of 2.7 kWh – a reduction by more than half. The difference is also evident in water consumption: on average, up to 348 liters less flow through the line per hour. With the Green Button, food businesses invest not only in environmental protection, but also in more economical cleaning. We’ll be happy to show you how and where using the eco program is particularly worthwhile in your operation.
