Güntner receives ATMO seal of approval for the fourth time in a row

Güntner has been awarded the prestigious ATMO Approved Natural Refrigerants label for the fourth consecutive year by ATMOsphere, a global market accelerator for clean cooling and heating solutions. This recertification underscores Güntner's ongoing commitment to sustainable innovation and the use of natural refrigerants. Introduced in June 2022, the ATMO Approved label is considered the global gold standard for identifying leading manufacturers and suppliers of natural refrigerant systems and components. Güntner received the label in its first year of launch in 2022 and has successfully renewed its certification every year since.

“This renewed confirmation from ATMOsphere reflects our ongoing focus on making a meaningful climate impact through innovation. We concentrate our efforts where they matter most – reducing emissions during the use phase of our products. This recognition underscores our leadership role in shaping a more sustainable future for cooling.”
Michael Freiherr Head of Technologies & Innovation and Managing Director, Güntner

Focus on PFAS-free solutions and emission reduction

An important new feature of the label criteria for 2025 is the increased focus on the elimination of PFAS (per- and polyfluorinated alkyl substances), which include trifluoroacetic acid (TFA). TFA is a by-product of the atmospheric degradation of many HFO and HFC refrigerants and is classified as a “planetary boundary threat” due to potential risks to human health and the environment.

“The label criteria for PFAS recognize companies' efforts to be PFAS-free. ATMO Approved companies have the vision and leadership necessary to navigate today's market and help organizations transition away from PFAS and globally warming synthetic alternatives.”
Marc Chasserot CEO and founder, ATMOsphere

Güntner is a founding member of the Coalition for PFAS Free Cooling & Heating, which promotes natural refrigerants as alternatives to PFAS in cooling and heating systems and advocates for ambitious PFAS regulations in Europe. ATMOsphere is also a founding member of this coalition.

Long-standing partnerships and customer satisfaction

Güntner's global customer base includes long-standing partners such as ABC Food Machinery, a Slovakian company working in the field of heating and cooling with ammonia (R717) and ammonia dimethyl ether (R723). Juraj Švingál, Technical Director at ABC, highlighted the more than 25 years of cooperation with Güntner and expressed his expectation that this partnership will continue for the next 50 years.

Four pillars of excellence

The ATMOsphere Label helps qualified manufacturers and service providers position their products and services in new markets for natural refrigerants. Certified companies can display the label on products, marketing materials, email signatures, and trade show booths to increase their visibility and make it easier for end users to identify top-tier suppliers.

To qualify, companies must demonstrate excellence in four key areas:

  • Company vision: A clear commitment to natural refrigerants as a core business.
  • Customer satisfaction: Positive references from end users confirming reliability and performance.
  • Measurable impact: Demonstrable reduction in CO₂ and TFA emissions.
  • Proactive training: Investment in training and education for employees and stakeholders.

Güntner is the 13th company to be approved for the ATMO Approved Label in 2025, joining a list of respected companies such as Ceptek, RefPlus, and Nihon Netsugen Systems.
