Before we decided to chose Mohn's personnel hygiene station concept from numerous suppliers on the market, there were access solutions in the form of barrier systems. When operating the water tap of the sensor-controlled basin, the barrier was opened,” explains Walter Maurer, production manager of the Ölz Master Bakery. “With the new system it is ensured that the hygiene requirements are complied with by all employees.”

After dispensing the soap application to both hands, the Ölz employees are given access to the production area - via the Highline hygiene station from hygiene technology specialist Mohn - and they are thus prompted to wash the soap off their hands.

Tamper-proof in Hygienic-Design 

In conjunction with the Siemens Logo control unit, the built-in sensors are considered tamper-proof. The access control unit automatically detects when both hands are not inserted in the two application openings and a soap application has not taken place. The coupled turnstile then remains blocked and access to the hygiene station is denied, the manufacturer promises.

The topic of hygienic and visual design was also important when awarding the contract. Particularly in hygiene-critical areas such as production, the avoidance of particulate contamination of the end product was a key requirement. "We were just as convinced by the stainless steel material as we were by the geometric design (hygienic design) of the equipment and systems of Mohn's hygiene station concept," explained Walter Maurer.

Energy saving through spring cap technology

"The topic of energy saving was also very well received," reports Walter Maurer. Ölz der Master Baker, itself a member of the "Energy Efficiency Network" and a partner of the “Climate active Pact 2030", has set itself the target of reducing CO² emissions by at least 50 percent by 2030.

At this point, the sole cleaning integrated in the installed hygiene station takes effect, which is activated by a patented innovation. The brush rollers are only activated when entering the walking grate and stop again immediately when leaving. Innovative, fully encapsulated sensors, in conjunction with the patented spring cap technology, ensure lower energy (power) consumption thanks to an ultra-short response time.

With conventional hygiene stations which are predominantly on the market, the brushes are already "running" before the personnel enters the walking grate to clean the soles.

Moreover, the very reliably working spring cap technology has the further advantage that sole cleaning functions just as smoothly for people with dark, rather than white, trousers. Hygiene stations with conventional sensor technology (reflection light scanners) are known to have the problem that people with dark clothing are not detected and the brush rollers do not work.

Siemens Logo!8 control unit – Upgrade to a smart machine

“Furthermore, it was important for us to be able to make flexible, simple and independent settings for the dosage of the soap or disinfectant used," explains Maurer. That is no problem with the Siemens Logo! 8 control unit installed by Mohn. The individual programmability also allows, for example, a delay in the control of the opening hours for the turnstile if a longer cleaning of the soles is desired.

With the installed Siemens Logo! 8 control unit, the implemented hygiene stations from Mohn are capable of much more than perfect personal hygiene. In the age of Industry 4.0, it is no longer technically complicated to upgrade them to a smart machine with an integrable wlan adapter and the "Intelligent Control" process visualisation system. With "Intelligent Control”, not only the visualisation of the system status is possible, e.g. if malfunctions are present. Diagnoses up to settings of operational parameters or flushing intervals, for example, can as well be carried out via this smart process visualisation solution. Also several smart machines can be networked with it and conveniently monitored from the workplace or tablet. Multi-compatible with many other systems, such as WinCC or Aveva.
