The ReiCat argon recycling system in the picture has a capacity of 200 Nm³/h at 6 bar. In addition to oil, nitrogen, oxygen and water are removed before the valuable gas is fed back into the production process. Monocrystalline silicon ingots, wafers, and modules are produced here. The system impresses with its sustainability, high availability, and gas purities of > 5.0 as well as a short amortization period. A direct reduction in operating costs is achieved.
