ATMOsphere Reapproves Natural Refrigerants Label for Zudek for Second Time

The ATMO Approved label is a global gold standard highlighting best-in-class manufacturers and contractors of natural refrigerant systems and components.

ATMOsphere, a global market accelerator of clean cooling and heating solutions, and publisher of NaturalRefrigerants.com, has for the second time reapproved the ATMO Approved Natural Refrigerants Label for Italian chiller manufacturer Zudek.

Zudek was initially approved for the label in October 2022 and was reapproved in February 2023.

ATMOsphere (formerly shecco) launched the label in June 2022 as a global gold standard highlighting best-in-class manufacturers of natural refrigerant systems and components around the world. Labels were also approved in 2023 for SCM Frigo, M&M Carnot, Zudek, MIRAI Intex, Novum and Temprite. In 2024, GTS, Nihon Netsugen Systems, Refra and Zero-C have been approved, Fenagy has been reapproved, and Secon, Güntner, TEKO and M&M Carnot have been reapproved for the second time.

In November 2023, ATMOsphere opened label registration for 2024 with a new category for contractors and installers who accelerate the adoption of natural refrigerant-based cooling and heating solutions. To date, contractors Equans Kältetechnik, SURE Solutions and General Refrigeration have been approved for the label.

“We are pleased to be re-approved by ATMO as it means we are moving in the right direction, sharing the same working ethic, and disclosing our sustainable philosophy to the world,” said Ivan Zudek, Partner at Zudek.

“Being a best-in-class natural refrigerant company means everything to us,” Zudek added. “It is what we have been working for since 1990. Natural refrigerants were the past, are the present and will be the only possible future if we want to save our beautiful planet.”

The ATMOsphere label is designed to help qualified manufacturers to market products to new customers and regions in the natural refrigerants marketplace, including products using CO2 (R744) and ammonia (R717). In addition, the label is meant to help end users identify best-in-class suppliers.

Once approved, companies can place the ATMOsphere Natural Refrigerant Label in a myriad of places, such as directly on products, marketing material, email signatures, company pitches and trade show booths.

“The label will be very visible in the global marketplace, and companies can take advantage of this to strengthen their brand,” noted Marc Chasserot, ATMOsphere Founder and CEO.

“By being global and multi-application, this label can help to create trust across the new applications and regions,” added Chasserot. “We want to use this multi-year label process to help move the market to cleaner solutions with natural refrigerant solutions over time.”

Founded in 1990, Zudek designs and manufactures customized low-charge ammonia chillers, including Ecomatik water-cooled chillers, and Airmatik air-cooled chillers. It also makes the Recumatik water-cooled ammonia heat pumps and Enermatik ammonia absorption chillers.

The water-cooled chillers offer temperatures from −45 to 80°C (−49 to 176°F), while the air-cooled chillers supply temperatures up to 45°C (113°F). The ammonia absorption chillers deliver temperatures from −60 to 1°C (−76 to 34°F).

A Zudek Airmatik chiller has improved the energy efficiency ratio (EER) of a cooling system at a pharmaceutical site in Belgium by 20% compared to its previous HFC-based unit, the company said. The chiller, which contains 100kg (220lbs) of ammonia, has an EER of 3.6 at an ambient temperature of 40°C (104°F).

Three pillars

To qualify for an ATMOsphere label, manufacturers have to demonstrate excellence across three pillars:

1) company vision;

2) customer satisfaction (measured via testimonials from multiple end users confirming the reliability, performance and service of these companies and products); and

3) measurable impact.

Commenting on Zudek’s refrigeration system, Michael Jimenez, Utilities Manager for Unilever RFM Ice Cream, said the system is “efficient and reliable” and Zudek’s service “is excellent.” In addition, the system is operating “above local regulatory standards,” Jimenez noted.

New criteria

The 2024 label also includes training criteria for the first time for new applications and renewals. “We want to recognize a proactive approach to training customers, partners, employees and suppliers to ensure we not only have the best-in-class equipment but the best-in-class installation and maintenance of these systems,” Chasserot said.

Another 2024 label criterion centers around per- and polyfluoroalkyl substances (PFAS), such as trifluoroacetic acid (TFA).

Recent research found significant levels of TFA – formed by the atmospheric breakdown of certain HFO and HFC refrigerants – in dust, drinking water and human blood in a study of households in Indiana (U.S.). The study characterized TFA as being part of the PFAS chemical family. TFA and TFE, another PFAS linked to HFOs, have pathways to forming HFC-23, a super potent greenhouse gas (GWP 14,600).

“The 2024 label criteria around PFAS acknowledges what companies are doing to ensure they are PFAS-free,” Chasserot said.

“ATMO Approved companies have the vision and leadership required to navigate the market today and help [companies] move away from PFAS and global-warming synthetic alternatives,” an ATMOsphere YouTube video says.

Additional new benefits added to the 2024 ATMO label include:

  • an annual report for environmental, social and governance (ESG) investors;
  • end-user tours at major trade shows to meet approved companies;
  • exclusive webinar targeting end users, consultants and contractors; and
  • end-user case studies, showcasing best practices.

ATMOsphere has been active in the natural refrigerant space for nearly 20 years. During this time, the company has:

  • published dozens of natural refrigerant-related market reports on market players, technologies and solutions worldwide across multiple applications;
  • hosted over 60 international natural refrigerant conferences, bringing together thousands of experts and hundreds of speakers over nearly 15 years, covering all the latest trends and players;
  • written thousands of articles reporting on natural refrigerant companies and products in the industry; and
  • sent representatives to hundreds of trade shows around the world, meeting with natural refrigerant experts face-to-face (in addition to countless individual meetings outside official events).

“We feel that, as an independent player with a global mindset and a global presence across all natural refrigerants and multiple applications, we are very well suited to provide this level of approval for the label,” explained Chasserot.

“Being a best-in-class natural refrigerant company means everything to us.”
