Don't raise any dust with the drums.

Gebrüder Wyss AG is very conscious of quality. And for over 20 years, the Swiss company has relied on SOLVARO. To be more precise, we supply the washing machine manufacturer with a stainless steel inner tub that is highly durable, even when in permanent use. It has to be. Because people with especially high mountains of laundry prefer to use WYSS MIRELLA machines – thanks to their durability. For example, for industrial and food service applications and multiple-family residences. The drum must keep running smoothly, even after ceaseless agitation, so the inner tub needs to be produced with a high degree of precision.

A clean result in every respect.

When it comes to washing machine drums, precision production is an absolute necessity. After all, we don't want to damage the laundry! And the inner tub of the drum must be extremely durable. To deliver these properties, we developed a special tool for punching the hole pattern in the 0.8-mm-thick stainless steel strip. This is how we achieve flared hole that ensure there are no burrs on the inside. Furthermore, the fine perforation prevents the throughput of too much water, making a contribution to consumption efficiency. Next, we punch cut-outs for the catch between the individual groups of holes. Wyss AG assembles the pieces and balances the drum itself – to guarantee that in the end, everything runs smoothly.

Installing parts; expanding our partnership.

Over the years, Wyss AG has focussed on expanding and developing its product range further. SOLVARO not only supplies a variety of inner tubs in a range of widths, but components for dryers as well. And we install simple controllers in specific washing machines. Particularly for markets such as Africa, in which the repair options are limited. Of course we are very pleased about our many years of fruitful collaboration. And this statement from Peter Wyss is also music to our ears: "A long-term partnership is the best proof of convincing quality."
