We believe in the power of natural refrigerants and their potential to create a better world through safe and sustainable use.

Solutions such as carbon dioxide, ammonia, hydrocarbons, air and water offer viable alternatives to synthetic refrigerants, which produce significant greenhouse gas emissions and are a risk to people and the environment.

For almost a century, natural refrigerants have been part of our business, and we have played a key role in spreading awareness of their benefits. We continue to test and explore their use in a state-of-the-art lab, and we strive to ensure that all our partners have the option to use them.

solving tomorrow's challenges today

Research and development have always been a driving force at Güntner. Across our state-of-the-art testing laboratories, we have international teams that are dedicated to designing the future of cooling solutions and heat transfer systems.

We believe innovation thrives on diverse multidisciplinary thinking and are encouraging the collaboration with external partners, experts and universities.
