The spread of mechanically transmitted viruses such as Tomato brown rugose fruit virus (ToBRFV) has highlighted vulnerabilities in everyday operational processes. Tire and caster contamination, often overlooked, has emerged as a key vector for pathogen transfer within facilities.
Addressing this challenge, Heute Maschinenfabrik has developed the ProfilGate® aqua system, designed specifically for continuous cleaning and disinfection in high-traffic greenhouse environments. As Maike Dorhs of Heute Maschinenfabrik explains, "mechanical routes of transmission are decisive – via hands, clothing, shoes, tools, and vehicle tires. Even the smallest traces of infected plant material are sufficient to introduce pathogens into an operation."
Integrated cleaning at every crossing
ProfilGate® aqua is installed flush with the floor at access points and transition zones, ensuring that all traffic, whether personnel, carts, or vehicles, passes through a cleaning and disinfection process without interruption. "The rolling surfaces of transport vehicles are cleaned and chemically disinfected in a single step at every crossing," she notes, highlighting the system's continuous and passive operation.

Proven reduction of viral load
Scientific validation supports the system's effectiveness. Studies conducted by Humboldt-Universität zu Berlin demonstrate that combining mechanical cleaning with chemical disinfection significantly reduces viral loads on tires and casters. "A recent study found that ProfilGate, in combination with MENNO Florades, reduces ToBRFV by up to 99% within seconds."

Seamless integration into workflows
A central requirement in greenhouse operations is that hygiene solutions must not disrupt workflow. ProfilGate® aqua addresses this through seamless integration. "Transport carts, vehicles, and personnel pass through the clean-off zone without stopping or performing any additional cleaning steps. This allows the system to integrate smoothly into existing processes even under high-traffic conditions."

Economic impact through prevention
From an economic perspective, the system's value lies primarily in prevention. ToBRFV outbreaks can result in yield losses ranging from 30% to 70%, alongside reduced market value due to visible fruit symptoms. "By reducing cross-contamination, ProfilGate aqua substantially lowers the risk of infection outbreaks. Return on investment results from more stable production conditions and lower downstream cleaning costs."

Supporting sustainability goals
In addition to biosecurity and cost efficiency, sustainability is an increasingly important consideration. ProfilGate® aqua operates preventively, reducing the need for extensive cleaning within greenhouse interiors. "Compared to conventional methods, the use of water and chemical disinfectants can be reduced. The sustainability benefit comes from a more efficient use of resources."

Operational reliability and user feedback
Feedback from greenhouse operators underscores the system's practicality. Many users report that it effectively addresses hygiene gaps while requiring minimal intervention. "Since the system operates without electricity, technical downtime is eliminated. No active operation is required." Maintenance is straightforward, with removable grates for routine cleaning and adaptable dosing systems for disinfectants.
