RENA Technologies (RENA) is a leading global manufacturer of wet chemical process equipment.

Founded in 1993, RENA has over twenty years’ experience in high-end chemical surface treatment. The business manufactures wet chemical process equipment that can treat products in chemical baths to improve or change the product’s surface characteristics.

RENA differentiates itself from the competition through its strong management team, technical know-how as well as its strong focus on R&D and engineering capabilities. Its modular, customisable batch and inline systems are developed and sold to customers in the green energy, medtech, semiconductor and, more recently, consumer glass end-markets. The business also offers custom-engineered systems, primarily for medtech applications, consumables, after-sales and advanced industrial services.

Headquartered in Gütenbach in Germany’s Black Forest, where it operates a production site, RENA also runs another three production sites in Berg and Mönchweiler, Germany, and Wykroty in Poland. Additionally, the business has established an R&D competence centre in Freiburg, Germany, and a quality control centre in China. Backed by a workforce of approximately 800 employees, RENA’s international presence is strengthened further by a global after-sales team.
