Sustainability

That depends on the system concept, process stages, components and rinsing strategy. More decisive than the consumption is how much stays in the circuit: With us, the water circuit is closed — process water is filtered, treated and reused instead of being consumed once and disposed of.

Via closed circuit operation, filtration and demand-based rinsing concepts. Where the requirement demands it, reverse osmosis and evaporators supplement the recovery. Depending on the system design, water savings of up to 60 % are possible this way. In concrete terms, this is implemented via cascade rinsing systems, vapor condensers and the return of the condensate into the process.

Nothing runs permanently that is not needed permanently. Each process and rinsing tank is monitored via a temperature sensor: If the target temperature is reached, heating stops; if it falls below, the heater switches back on by itself. The same principle applies to other consumers — in a chamber cleaning system, for example, the side channel blower can go into standby mode as long as there is no component in the chamber. So that the generated heat also stays in the system, the systems are thermally insulated. Control and insulation work together: One generates only what is needed, the other keeps it. Where the site allows it, the process heat does not have to be generated separately at all — the system can be connected to an existing district heating supply. Where this is not possible, it gets its own heating systems. Drying also counts here: It is designed according to part geometry, material and required residual moisture — as blower or vacuum drying. A drying process that runs longer than necessary costs cycle time and energy at the same time.

Via three ways that work together. The process water stays in the closed circuit — filtered, treated and reused, instead of consumed and disposed of. The optimized filtration discharges the contamination as a concentrate, which reduces disposal volumes. And the chemical input itself stays low because the systems are isolated from one another. Added to this is bath maintenance: If only what the bath load actually requires is replenished, instead of following a fixed schedule, consumption drops without the cleaning effect diminishing. How far this can be reduced in the individual case is decided by the system design — contamination, process, bath load and the required technical cleanliness set the framework.

With us, sustainability is a boundary condition of design engineering, not a label added afterwards: low-maintenance, energy-efficient, closed media circuits with water treatment. The ecological and the economic advantage coincide here — closed circuits reduce running costs and disposal volumes at the same time.

On the task, not on the machine — which is why there is no catalog value for it. What determines it: the part geometry and the type of contamination, production volume and cycle time, the chosen cleaning method with temperature, pressure and flow rate, the drying method, the operating hours, the water treatment and how far the circuits are closed — and above all the required technical cleanliness, because it limits the effort upwards or forces it. Two systems of the same machine type can differ considerably in this. That is why we consider these variables in the system design and not afterwards: What is oversized here consumes too much over the entire service life of the system.
