What is the AquaBatch?

What it does

The AquaBatch filters out fibres, hairs, lint, sand  and other solid particles  in the pre-wash, main wash or the rinse zone of your continuous tunnel washer. These particles and fibres are removed definitively from the washing process and are therefore not flushed on to the next compartiment. Removing particles and fibres means improved end quality of the washed textile because you are (pre)washing/rinsing with cleaner water. The AquaBatch filters continuously as needed for each cycle.  Our one-step technology means that the heat in your wash water is also preserved to the maximum.  The AquaBatch is  designed to give you higher end quality with the minimum of fuss.

Performance boost

With up to 95% of your wash water now filtered clean before entering the next compartiment,  and more or less at its initial temperature, you will see a big quality boost in your process.  Big improvements for a modest investment.

How it works

The AquaBatch continuously filters process water from the chosen zone of your tunnel washer. The heart of the AquaBatch is its depth-filtration technology. Layered discs trap all dirt – even hairs cannot slip through. What’s more, the filters are self-cleaning, running an automatic backflush whenever required. That minimizes operator time. The AquaBatch connects inline to one tunnel washers compartment and will treat up to 15m³ wash water per hour. The AquaBatch is a fully automatic system, pre-programmed, and with a display which allows your personnel on the ground to monitor exactly how everything is running. Furthermore, the filter is enclosed for maximum hygiene, particularly important if you have health-care customers.  The AquaBatch is simplicity itself: compact, easy to connect and it will quickly become a workhorse  for high end quality.
