The Weiss Green Mode

weiss green mode energy saving


In the ever-evolving landscape of testing labs, the quest for efficiency, sustainability, and cost-effectiveness remains paramount. One company leading the way in this regard is Weiss, renowned for its commitment to reducing power consumption while maintaining top-notch test specifications. Over the years, Weiss chambers have consistently outperformed competitors in energy efficiency, and now, they have taken it a step further with Green Mode on many of their chambers.

Thermal Shock Chamber with Weiss Green Mode

Green Mode: A Paradigm Shift in Energy Efficiency

Weiss has embraced the urgency of minimising electricity usage without compromising testing standards. Green Mode exemplifies their dedication to environmental responsibility. This innovative feature optimises energy consumption without sacrificing the quality of test results.

High-Efficiency Design: A Standard for Weiss Chambers

Weiss has always prioritised energy savings by incorporating high-efficiency motors and refrigeration systems as standard features in their testing chambers. This proactive approach ensures that every Weiss chamber is designed with sustainability in mind, setting a new benchmark in the industry.

Smart Software for Smarter Energy Savings

One of the standout features of Weiss chambers is their intelligent software, which goes beyond conventional expectations. In thermal shock machines, the software takes a dynamic approach to power usage. During prolonged dwell times in thermal zones, the system intelligently turns off heaters or compressors to conserve power. The automated reactivation, precisely timed before the cradle moves, showcases Weiss’s commitment to efficiency at every stage of the testing process.

Efficiency Unleashed: Thermal Shock Machines

Weiss chambers redefine energy efficiency in thermal shock machines by optimising dwell times. When the system detects extended dwell periods, it strategically shuts down heaters or compressors, resulting in significant electricity savings. This not only reduces power consumption but also contributes to a more stable testing environment, minimising temperature fluctuations.

Elevating Energy Efficiency in Stress Chambers

In stress chambers, Weiss introduces groundbreaking measures for cooling optimisation. When cooling requirements are -20°C or higher, or during humidity control (climate control), the low cooling compressor is deactivated. The system seamlessly transitions to a single compressor operation, utilising a dedicated heat exchanger (evaporator). This innovative design not only maximises savings but also ensures optimal performance during extended dwell times.

Quantifying the Savings: Up to 45% Electricity Savings

Weiss doesn’t just promise energy efficiency; it delivers measurable results. Laboratories adopting Weiss chambers can experience electricity savings of up to 45%. These substantial savings are coupled with reduced temperature fluctuations and lower cooling water consumption, making Weiss chambers the preferred choice for environmentally conscious testing facilities.


Weiss is commitment to energy-efficiency, Green Mode stands as a testament to the company’s dedication to sustainable testing practices. Laboratories choosing Weiss chambers are not only investing in cutting-edge technology but also contributing to a greener and more efficient future for testing labs worldwide. With Weiss, the path to superior testing outcomes is now paved with environmental responsibility and economic prudence.
