Productfamily SALIX

Wet Scrubbing of Waste Gases from Wet Bench Applications

SALIX is our point-of-use wet scrubber family specialised on process waste gases from single wafer clean wet benches. The system allows high flexibility towards process changes and saves space and cleanroom air, compared to older concepts.

Burn/Dry — Pyrolysis

The process waste gases are burnt in a decomposition zone. If required, a fuel gas can be applied. Depending on the chemical composition of the waste gases, various reactions take place, such as oxidation, reduction or pyrolysis.

The Burner Product Family LARCH was especially designed for MOCVD processes in the LED and GaN industry. It is capable of treating large flows of the typical gases hydrogen and ammonia.

Worldmap DAS Offices 2023

DAS teams work in 11 offices on four continents on the development of our products and the service for our installed base. In this way, we facilitate fast response time, intense customer support and a constant eye on industry trends.

The internationalization of the company has started at a very early stage. At the end of the 1990ies founder Dr. Horst Reichardt dared to enter the Taiwanese market and explored the Asian market from there. Few years later, the foundation of branches in the USA and Singapore followed. Since 2010 DAS Environmental Expert is operating also in the South American market.

2022 DAS EE opened its new office in Malaysia. With this milestone, DAS EE reacts to the growing demand for its point-of-use waste gas treatment systems in the regional semiconductor industry. Besides the service for the existing installed base, joint development projects with customers will be enforced. These projects will focus on innovative solutions in energy & resource management.
