CCR Commercial Refrigeration, a supplier of commercial and industrial turnkey CO₂ (R744) refrigeration systems and services, has announced that as of July 15, its entire range of CO₂ gas coolers will be manufactured to operate at 130bar (1,885psi).

“As temperatures get higher each year, performance and reliability under extreme conditions have never been more crucial,” CCR said. “That’s why we are proud to announce [this] major evolution.”

The company, headquartered in Germany, installs CO₂ cabinets, racks and other heating and cooling equipment under the brands Carrier Commercial Refrigeration (licensed by Carrier Corporation), Profroid, Celsior and Green & Cool.

Improved operation: In ambient temperatures above 38°C (100.4°F), the 130bar-rated rack increases cooling capacity by 20% compared to a 120bar (1,740psi) CO₂ system, CCR said, with a COP increase of up to 18%.

• A 130bar system increases robustness and safety, without the need for adiabatic cooling, according to the company.

Equipment/capacities: CCR supplies CO₂ gas coolers, racks and condensing units, with capacities ranging from 10kW (2.8TR) to beyond 1MW (284TR).

• The company’s QuietCO₂OL, MiniCO₂OL, MaxiCO₂OL, GC5 coolant distribution unit, PowerCO₂OL, CO₂ Soprano, CO₂ Alto, CO₂ Tenor and Centrifugal CO₂ Soprano/Tenor are now available at 130bar.
• The 130bar-rated gas cooler comes with no change in system tonnage size, price or spare parts, according to CCR.
• The QuietCO₂OL remains available in a 120bar version.

Additional options: Other manufacturers produce gas coolers rated to or beyond 130bar, including Güntner and Enex Technologies.

• Although German manufacturer Güntner’s standard CO₂ gas cooler is rated to 120bar, the company can produce 130bar units, Matthew Belford, Senior Key Account Manager at Güntner, told NaturalRefrigerant.com in October 2023.
• In January 2024, Enex Technologies launched a transcritical CO₂ flat gas cooler rated to 140bar (2,031psi), capable of handling cooling capacities from 15 to 900kW (4.3 to 255.9TR).

Quotable: “Whether you’re planning new installations or looking to strengthen existing ones, this step forward ensures your refrigeration stays efficient, sustainable, and ready for tomorrow’s climate challenges,” CCR said.

“As temperatures get higher each year, performance and reliability under extreme conditions have never been more crucial.”
