The tiniest details count in our R&D and quality assurance test chambers. Physical requirements are rarely as high in real-world applications. Our test chambers are subjected to continuously changing temperature and pressure loads, corrosive atmospheres and extreme moisture. To meet these challenges, we design and manufacture special sandwich elements with many different finishes and surface coatings. Sealed gas-tight from the inside and diffusion-resistant from the outside, they fulfil the most demanding customer requirements.
