Advantages of the WS industrial washing machine

Suitable for: Horse blankets and equestrian sports textiles, industrial products and components, textile cleaning on ships, towels and bathrobes, tablecloths and serviettes, bed linen, outerwear and wet cleaning, mops and cloths, dirt-trapping mats and pet blankets, fire brigade and rescue service clothing, PPE and equipment items such as respiratory protection masks, kitchen linen, curtains and drapesand much more.

Optimal washing results

Highlights of the robust WS washing machine made in Germany

Automatic load size detection

The maintenance-free PTS 3 Power Transmission System developed by us only consumes as much energy as is actually needed for the respective activity, e.g. power consumption during spinning decreases the drier your laundry becomes, or if the WS commercial washing machine is not fully loaded. The PTS 3 with its trendsetting ultra-efficient motor reduces current spikes, detects and controls unbalance situations, ensures quiet operation and features continuously adjustable washing and spinning rotation speeds as well as gentle starting and wear-free braking of the drum without the use of mechanical braking components. What PTS 3 means for you is flexible, economical, safe and innovative washing.

Our intelligent WRS water regulation system continuously monitors the water level and adapts to the circumstances automatically. For example, the WS recognises when there isn’t a full load, meaning less water is used. This means that STAHL’s WS commercial washing machines always have the lowest possible water consumption and are the most economical washing machines for your commercial purposes.

Impressively dimensioned drum bearings

The massive bearing of the WS industrial washing machine is the impressive expression of quality of our STAHL laundry machines. It was developed by us and perfectly corresponds to our philosophy of the best quality and longevity. The drum bearing has impressive dimensions, is equipped with an automatic lubricating system and has multiple protection against suds. 

Rigidly-mounted Drum

The STAHL drum is suitable for washing all types of textiles, even heavily soiled mops or dirt-trapping mats, in just one machine without coarse dirt remaining in the drum after the wash cycle.

The STAHL stainless steel washer drum has funnel-shaped and gently curved outwards-facing perforations. This means that your laundry is very gently handled, and the desired friction effect increases within the laundry, but decreases on the metal. The number of the holes and their size has been optimised in order to provide you with the maximum possible level of efficiency. They ensure that any suds are discharged quickly, which is important, especially during the spin cycle, in order to achieve the desired residual moisture level of approx. 80% quickly with minimal energy consumption. With the STAHL drum perforations you also benefit from the fact that no coarse dirt from mop covers, dirt-trapping mats, kitchen linen and horse blankets remains in the drum after the wash cycle. Depending on the washing machine size, the WS is equipped with between four and six drum paddles, which are also perforated. This paddle technology ensures greater movement and quicker immersion of your laundry, thus saving you time and energy. Another benefit of our drum is the dome on the rear side. This reduces the area that does not come into contact with the laundry compared to conventional systems. The quantity of unused water is therefore reduced and this also saves you water and energy.

Generously dimensioned stainless steel drain valve

The large stainless steel drain valve, available as an option, without ball, rubber membrane or strainer ensures a reliable workflow even when there is coarse dirt in the laundry and can be accessed from the front via a large service flap.

The stainless steel drain valve developed and produced by us is large and step-shaped, which prevents dirt from being deposited and foreign bodies getting stuck in it. This guarantees you a reliable and economical workflow without the need for time-consuming maintenance. The stainless steel drain valve in our washing machines is controlled by water or air and therefore remains closed even if there is a power failure, which would otherwise result in the water being lost and you having to restart the washing process. This promises operational reliability when using STAHL commercial washing extractors. Another advantage for you is that they are wear-free, as there is no rubber diaphragm, ball or strainer is installed in the STAHL stainless steel drain valve. As a result, you benefit from a reduction in maintenance costs.

High-quality detergent compartments made from stainless steel

Stainless steel detergent compartments prevent the washing powder from clumping together and always remain hygienically clean.

Intuitive operation via large touch display

Our flexible FREEpro touch control unit allows you to use the WS in many different ways. The control unit features an impressive 99 freely programmable washing programs, as well as the option to adjust various parameters during the washing process. These adjustable parameters include  temperature, holding time, water level, speed, rinse time, spin time and spin speed.

The washing solutions that come as standard include programmes at a variety of temperatures and with various rinse processes and spin speeds, as well as single, double or triple soak processes. You can simply select one of the washing program packages, e.g. for: Hotels, cleaning services, care homes, fire brigades, wet cleaning programs for textile cleaning, equestrian sports and much more.  

The FREEpro touch control unit allows you to store and select thermal and chemo-thermal disinfection programs which are compliant with the guidelines of the Robert Koch Institute (RKI). 

You also have the option to treat mops and towels with cleaning agents or surface disinfectant directly in the machine. This means that the items are ready for use again straight after washing. 

An overview of the advantages of the control unit:

  • Large display
  • Dialogue-based programming
  • Steplessly adjustable parameters
  • No memory cards or back-up batteries necessary
  • Timer with week and weekend function
  • Constant process monitoring
  • Visualisation of program sequence
  • Troubleshooting system
  • Ability to retrieve comprehensive statistical information
  • Additional online functions
Stable side parts made from stainless steel

Stable stainless steel side parts, exclusively commercial industrial components and a no savings policy on material thickness make the STAHL WS professional washing machine a high-quality and long-lasting investment.

Powerful washing mechanism

During the washing process the laundry is influenced not only by mechanical forces but also by changes in water pressure, which increases the efficiency of the WS. You save energy, water, time and detergent. This is achieved through a pioneering design used exclusively in STAHL washing machines. The circular drum does not revolve in an external circular drum as is usually the case because we have found the perfect shape for the external drum. The water pressure increases at the narrowing and water flows through the drum perforations and drum paddles quickly and under pressure, immersing the laundry.

Innovative overflow rinsing process enhances the level of cleaning in the wash

In the overflow rinsing process, the detergent with the dirt bound to it is removed by the rotary movement of the drum via the lower positioned overflow. This saves you a complete rinse cycle and you benefit from shorter washing times and reduced water and energy consumption. Furthermore, the laundry with the detergent and the dirt bound to it is not passed through the bottom drain, as is the case with the conventional rinsing process. This increases the level of cleaning in the wash and reduces the wear on your laundry.

Further features
  • Manual detergent dosing via detergent box or automatic liquid dosing via all common pump systems can be freely selected at any time
  • Strong, hot-dip galvanised machine frame
  • Easy loading and unloading of laundry for staff due to ergonomic height of the large fill opening
