Environmental simulation with CO2 refrigerant
Weiss Technik

Weiss Technik is converting its test chambers to a new CO2 refrigeration technology. The EU's F-gas Regulation has placed restrictions on the use of refrigerants with a GWP level of more than 150, meaning that from January 1, 2025, test cabinets and chambers sold in the EU by any manufacturer should have a GWP level of less than 150.

The new Weiss Chamber with CO2 refrigerant produces GWP 1. It is safe, economical and standard compliant.
Weiss Technik has already installed standardized refrigeration circuits in various test chambers and thoroughly tested them, including rigorous temperature-change tests.
CO2-equipped devices easily pass test standards such as IEC 60068-2-14 Nb for thermal shock tests or ISO 16750-4 for electrical and electronic vehicle equipment. Temperatures as low as -50°C are reliably reached in the test space.

The use of CO2 in the test chambers means that smaller, less expensive components can be used, and the equipment is quieter and more energy efficient than before.
Another advantage is that the technology conforms with the new EU F-gas Regulation without exception, so there are no documentation and leak detection requirements. The new components can handle the higher pressures associated with CO2, and Weiss Technik guarantees the same service life as previous units. Operating conditions, including coolant and room temperature, also remain unchanged. The CE markings, including the Pressure Equipment Directive 2014/68/EU and DIN EN 378, which have been in place for decades, also remain valid as the regulations for the installation conditions of refrigeration systems.
