From -60 to +120.
From research question to industrial installation. We think along from the first idea.
For research, production, and validation.
At Nijssen, your research question forms the foundation of every climate simulation project. We take the time to understand your research, advise on the most appropriate stakeholders and define the required test conditions with precision. In doing so, we look beyond the test environment itself and consider all factors that need to be accurately controlled, including temperature, humidity, lighting, gas concentrations, water irrigation and other environmental parameters that may influence the outcome of the research.
With our experience, we develop tailor-made climate simulation solutions that allow products, materials, plants or processes to be tested under realistic and reproducible conditions. This creates a reliable test environment in which you can determine, well before market introduction or application, whether everything meets the required standards and expectations.

Nijssen implemented two new climate growth chambers that seamlessly connect to the existing installation and previously installed facilities.
Thanks to decades of collaboration, there was extensive knowledge of the location and systems, allowing engineers, work planners, and programmers to meticulously prepare the expansion.
"Our partnership with Nijssen dates back over 20 years. That continuity and mutual trust ensure projects run smoothly and efficiently."
