Fricke und Mallah supplies microwave technology of the highest quality to numerous branches of industry. The expertise of our experienced high frequency engineers enables us to understand the most demanding applications and deliver solutions that convince our customers.
Manufacturing honeycomb ceramics for catalytic converters and diesel particulate filters requires a sophisticated drying process. Microwave drying has established itself here, as this technology meets the requirements for homogeneous drying.
The geometry of the honeycomb ceramic with low wall thicknesses and the low thermal conductivity of the material ruled out classic drying methods such as hot channel technology or infrared early on.
Due to their modern semiconductor-based HF generators, our systems are excellently suited for these difficult operating conditions. With continuous waves at frequencies in the range between 2400 MHz and 2500 MHz, they produce more precise and homogeneous results.
