Continuous dryers specially designed for the circuit board process in the vertical process ensure fast, residue-free drying of circuit boards, shape-etched parts or other substrates after the wet chemical process. The circuit board is automatically transported through the drying zone and is quickly available for the subsequent processing steps of lamination or surface treatment. The range is expanded by universally applicable drying ovens for drying, tempering and heating circuit boards and substrates. The high-quality stainless steel ovens offer extensive equipment and program functions. Convenient and application-specific special equipment ensures a wide range of applications.
