ENGIE launches redesigned air-cooled chiller

The QUANTUM series, company says, is available in 28 versions, of which 14 use R-1234ze, with the remaining 14 use either R-134a or R-513a

Lindau, Germany, 8 July 2019: ENGIE Refrigeration on June 24 launched a redesigned air-cooled Quantum series air chiller, the company announced through a Press communiqué. In total, 28 versions of the QUANTUM Air series are available, the communiqué said, adding that 14 of the models use the refrigerant R-1234ze, and the remaining 14 use either R-134a or R-513A.

“We put the concentrated expertise of our team into the redesigned QUANTUM Air models, along with our wealth of experience from 16 years of refrigeration solutions with our previous QUANTUM chillers,” said Jochen Hornung, CEO, ENGIE Refrigeration. “On this basis, our QUANTUM Air is the ideal way for us to help our customers meet the most stringent economic and ecological requirements in an increasingly complex market environment – today and in the future.”

According to the communiqué, the new air-cooled QUANTUM scores above all in terms of its efficiency, performance, control system and serviceability. First, the new models considerably exceed even the levels of efficiency of the previous series, something Lindau has achieved through intelligent connections between the different components, the communiqué quoted the company as saying. Second, the QUANTUM Air makes more efficient use of operating fluids, as the refrigerant fill level has been reduced significantly – regardless of whether R-1234ze, R-134a or R-513A is chosen, the communiqué said. This twofold increase in efficiency during operation and in the use of operating fluids leads to a smaller ecological footprint, the communiqué further said. In addition, a novel structural design allows for a reduction in the size of the chiller without affecting its performance, the communiqué added.

According to the communiqué, the new QUANTUM Air achieves a refrigeration capacity of between 250 kilowatts and two megawatts for the first time. This means the chiller outperforms not only its predecessor model but all air-cooled chillers with magnetic-bearing compressor technology that are currently available on the market, the communiqué quoted the company as claiming. Its design concept, the communiqué said, ensures the same refrigeration capacity as its predecessor while being not only smaller but also significantly lighter. This considerably reduces roof loads – a significant advantage if the machine is set up outdoors on top of buildings, the communiqué said.

Another feature of the QUANTUM Air is its modified control system, the communiqué  said, which facilitates improved control and regulation options that are optimised in terms of energy efficiency. Furthermore, it enables even better adaptation to customer-specific cooling requirements at every operating point and at different ambient temperatures, the communiqué said. In addition, ENGIE Refrigeration has chosen new components for the QUANTUM Air and recombined the individual machine components according to a sophisticated modular principle, the communiqué said. This, the communiqué added, reduces delivery times and makes the machine easier to service, as it will be easier for the service technician to enter the interior of the machine during maintenance in future.
