Particle-free and purity are the fundamental requirements for products used in cleanroom environments. Stainless steel grades are specifically designed for this purpose and can be used in a variety of applications. New developments combined with innovative ideas offer solutions to the industry.

Stainless steel components and chains offer countless possibilities for use. Increasingly important is their application in cleanrooms and environments where particle-free conditions are crucial.

Challenging environmental conditions, material- and time-intensive cleaning processes of the components used impose high demands on surface quality. The best corrosion resistance and an excellent surface structure create an ideal unit for cleaning. The resulting increase in safety and emission-free operation guarantees economic efficiency.

Manufacturers of cleanroom-compatible lifting components made of stainless steel

The cromox product line from Ketten Wälder GmbH from Bad Endorf is used worldwide across various industries and applications. The non-rusting chains made of high-alloy stainless steel are also used in cleanrooms due to their special surface and high manufacturing quality. Ketten Wälder has recognized the potential of stainless steel products in this area and develops targeted solutions in collaboration with key customers.

New products with numerous application possibilities

Now, Ketten Wälder has added an impressive new item to their range with an innovative product novelty: the cromox Chain Hoist or also cromox lifting clamp, short CCH. The most important feature of the hoist for cleanroom applications is its extremely low particle emission, which is guaranteed by a unique design. The exterior is completely made of high-quality, stainless steel. The CCH also features a fully sealed brake and gear unit, preventing particle emission. To complete the overall package, the cromox CCH comes in a standard version with a rotating hook mount and a load hook that rotates under full load to ensure maximum flexibility. Fully in-house production guarantees the highest availability.

Electropolishing to improve durability

The company Ketten Wälder offers key components for cleanrooms in electropolished versions. Products with this surface treatment are used in the semiconductor, pharmaceutical, chemical industries, and in medical technology.

Advantages of electropolishing include smooth and shiny surfaces, metallic purity, optimal cleaning behavior, particle-free operation, significantly reduced tendency for deposits, markedly decreased outgassing behavior, high corrosion resistance, reduced friction, and consequently less wear.

Safety as the top priority

Chain tracks lift heavy and high-quality goods. Ensuring safety, starting with the development of cromox lifting systems, is of utmost importance. Once again, the high significance of corrosion-resistant items is evident. For example, areas affected by perforations or rust reduce load capacity and pose safety risks. Electropolishing maximizes the corrosion resistance of the high-quality material and thus minimizes safety risks. The specialists at Ketten Wälder are happy to advise their customers according to the project requirements.

Innovating into the future

The new cromox catalog 2020, recently published by Ketten Wälder GmbH, presents product innovations such as safety load hooks and chain shortening devices. A dedicated section is also allocated to custom special constructions.

With continuous new developments combined with innovative ideas and proven processes, Ketten Wälder offers the right components for use in cleanrooms.
