The automotive industry continues to lead in technological advancements, with sustainability now a key priority. As companies work to minimize their environmental impact, innovative solutions are essential.
Huber’s sustainable temperature control technology is one such solution, playing a vital role in enhancing efficiency while supporting eco-friendly manufacturing processes.
Temperature and flow control (with optional accessories) are central to various automotive testing applications, ranging from safety assessments, such as evaluating component and material flammability, to stress and load evaluations.
Huber’s temperature control units, combined with flow control of the circulating test fluid, offer precise, reliable, and repeatable flow and temperature management, thereby contributing to the development, quality, and safety of automotive components.
Global Leader in Temperature Control Technology
Since 1976, Huber has been a pioneer in ecological innovation. All of its models use natural refrigerants or offer the option to include them, including CO2. Additionally, Huber designs its products with high-quality, recyclable materials, ensuring both longevity and sustainability.
Unimotive GL – CO2-Based Automotive Temperature Control Technology
Huber’s commitment to sustainability extends to the automotive sector. The new Unimotive GL (Green Line) model series functions with the natural refrigerant CO2, providing a 100 % environmentally friendly alternative to units utilizing synthetic refrigerants.
The Unimotive GL series is specifically designed for automotive applications and direct operation with water-glycol. Its operating temperature range (in the “XT” variant) is -45 °C to 150 °C.
Typical applications include temperature simulations, material tests, and temperature-dependent load and stress tests for automotive parts and functional components.
The Unimotive GL series represents another landmark in the development of environmentally friendly refrigeration technology at Huber. The heating and cooling systems operate in an environmentally responsible manner, using CO2 as a refrigerant.
CO2 (also known as R744) is a natural component of air that is abundant, safe, and non-flammable. As a proven efficient refrigerant, it has been used in refrigeration technology since the 19th century.
With zero ozone depletion potential (ODP = 0) and an ultra-low global warming potential (GWP = 1), CO2 is an environmentally friendly choice. It is widely available and does not require significant energy for production. Additionally, it offers key advantages, including non-flammability, non-toxicity, and chemical stability.
By using this climate-friendly refrigerant, manufacturers can significantly reduce their carbon footprint throughout the entire production cycle.
A Greener Road Ahead
Huber’s sustainable temperature control technology represents not just a solution but a commitment to a greener future. As automotive manufacturers adopt these innovations, they drive progress while contributing to the preservation of our planet.
Quality, performance, reliability, repeatability, and environmental stewardship converge–a testament to Huber’s legacy.
Huber’s eco-friendly temperature control technology transcends mere numbers and machinery; it is about building a sustainable automotive landscape.
