Sustainability in Thermal Analysis: How NETZSCH is Leading the Way
NETZSCH Analyzing & Testing has taken significant steps to ensure that its instruments align with the sustainability goals. With state-of-the-art Eco-Line instruments and responsible manufacturing practices, NETZSCH is committed to reducing its carbon footprint and enabling customers to achieve their sustainability objectives.
Sustainability has become a decisive factor for industries worldwide, and the field of materials characterization is no exception. As companies strive to reduce their environmental impact, they are looking for innovative solutions offering high performance while minimizing energy consumption and waste. NETZSCH Analyzing & Testing has taken significant steps to ensure that its instruments align with these sustainability goals. With state-of-the-art Eco-Line instruments and responsible manufacturing practices, NETZSCH is committed to reducing its carbon footprint and enabling customers to achieve their sustainability objectives.
A Commitment to Sustainable Innovation
At NETZSCH Analyzing & Testing, sustainability is not only about creating environmentally friendly products, but also about ensuring responsible manufacturing processes. The company follows an ecodesign philosophy that focuses on designing instruments for longevity, easy repair and optimization. Unlike many competitors, NETZSCH provides spare parts for decades, ensuring that customers can maintain and upgrade their instruments rather than replace them.
In addition, NETZSCH has achieved a remarkable 60% reduction in energy consumption and CO₂ emissions per analyzer produced in 2024 compared to 2018 levels. This improvement underscores the company's commitment to reducing its environmental footprint throughout the manufacturing process. Moreover, the company actively collaborates with local specialists at all sites to uphold corporate social responsibility (CSR) and environmental protection standards, earning the BME RPO Level 1 Bronze Certificate for its sustainable procurement efforts.
Energy-Efficient Analysis Instruments
To complement its sustainable manufacturing efforts, NETZSCH has developed a series of Eco-Line instruments that help customers reduce energy consumption and operating costs without compromising on performance.
These instruments incorporate, for example, Eco Mode features that automatically power down components when not in use, significantly reducing energy requirements.
HFM 446 Lambda Eco-Line
Designed to measure the Thermal ConductivityThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity of insulation materials, this heat flow meter optimizes energy consumption through:
- Shorter measurement times to reduce power consumption
- Eco mode that turns off non-essential components when idle: In standby, the HFM 446 Lambda can be switched to the energy-saving Eco-Mode or to Idle-Mode for a quick measurement start. The timing for when each mode is active can be adjusted via a scheduler.
- Available in three sizes dedicated to small, medium and large-sized specimens
TG 309 Libra® Thermobalance and DSC 300 Caliris®
The TG 309 Libra® offers a high-precision solution for thermogravimetric analysis with an eco-mode function. By setting a user-defined time schedule, the thermostat switches off automatically when it is not needed, helping reduce operating costs and environmental impact. The purge gas can also be reduced as required in eco-mode. Discover more!
The same function is provided by our DSC 300 Caliris® Differential Scanning Calorimeter:
Simultaneous Thermal Analysis by means of the STA 509 Jupiter®
The STA 509 Jupiter® is the latest advancement in simultaneous thermal analysis, offering improved energy efficiency and precision in measuring mass changes and energetic effects under controlled temperature conditions:
To obtain accurate thermogravimetric results with low drift behavior, most manufacturers have to resort to thermostatic control using a water circuit. Having to continuously run the thermostat consumes a lot of energy and produces waste heat, which subsequently needs to be regulated by air conditioning.
NETZSCH has succeeded in eliminating the external thermostat. The temperature of the weighing chamber is now controlled electronically while maintaining excellent temperature stability. By eliminating the thermostat, the energy consumption of an STA 509 Jupiter® for an average user is reduced by 70%*, which translates into a savings of 5,000 kWh of electricity per year. Another way to run the unit more economically is to use the Eco Mode, which turns off the gases when they are not needed.
