Their portfolio includes highly customized products tailored to customer needs. Regardless of the requirement, Kajketsu stands for effective constructions and efficient production. They combine interdisciplinary expertise, traditional craftsmanship, and innovative design. All products are developed and implemented efficiently and sustainably. Tameson spoke with Kaj Sewald, Managing Director of Kajketsu GmbH, about the "Mobile Facade Cleaning System" project.
For this project, the detailed product descriptions and competitive pricing of Tameson products were particularly convincing for the experienced engineer. Solenoid valves, ball valves, and associated flow control products are used in a self-contained mobile facade cleaning system. The company's goal is always to find the ideal customized solution for their customers, as with the mobile facade cleaning system.

360° Perspective on Customer Requirements
Kajketsu focuses on highly specialized and individualized projects in the small to medium-sized segment. They combine their interdisciplinary competencies with services in steel, metal, and timber construction, measurement, control, and electrical engineering, and mechanical engineering. This allows them to offer their customers tailored solutions that go beyond mere construction and production. The result is answers to engineering questions that are thought out in the finest detail.
Kajketsu's approach offers a 360° perspective on requirements—from inception, through the current state, and into the future. For this, the company draws on its own broad knowledge base from various industries. Their extensive expertise enhances collaboration with external service providers, improves quality, and strengthens customers for future challenges.

The Mobile Facade Cleaning System
Kajketsu uses Tameson's solenoid and ball valves in their mobile facade cleaning system to make the process easy and efficient for users. Here's a brief explanation of how it works:
- Self-contained system: All the important parts of the cleaning system are inside a trailer. The user controls everything from a panel on the outside, making it easy to manage the cleaning process without going inside the trailer.
- Central control: The system uses a computer to manage everything. It takes signals from sensors and uses them to control the Tameson valves. This helps the user see important information, like how much water is available and the condition of the filters, on a screen.
- Mixing system: The system mixes water with cleaning or sealant solutions. It uses a proportional solenoid valve and a PWM controller to get the right mix. The user can set how much cleaner or sealant to mix with the water.
- Valves for solutions: The system uses electric ball valves to draw in cleaning or sealant solutions. This allows the user to easily switch between cleaning and sealing.
- Automatic flushing: A solenoid valve automatically cleans out the mixing system to prevent different solutions from mixing together.
- Water hose control: A ball valve controls the water hose, allowing the user to fill or drain the water tank with the same hose.
- Water level control: Another solenoid valve stops the water supply when the tank is full to prevent overflow.
- Reliable components: Important parts like pumps, water heaters, and generators are inside the system. They are designed to work reliably and are only accessed for maintenance.

Product Descriptions and Fair Prices
Kajketsu GmbH discovered Tameson while searching for solenoid valves and ball valves for their individual applications. "The detailed descriptions, such as of the proportional valve, on your website helped us get an accurate picture of the functionality. Other providers do not have such precise application descriptions or not as detailed," explained Kaj Sewald, Managing Director of Kajketsu GmbH, and praised: "The prepared product and application information as well as fair prices were decisive for us."
