Chillers
Quantum refrigerant change
ENGIE REFRIGERATION HAS added a new refrigerant to its portfolio.
R-515B, which is non-toxic and non-combusti- ble, is now available for QUANTUM chillers as an alternative to R-1234ze.
ENGIE Refrigeration is one of the first manu- facturers in the world to use R-515B which was developed as an alternative to R-134a.
It can be used instead of R-1234ze in the form of a drop-in refrigerant, according to ENGIE’s head of product management, Daniel Keller.
“Refrigerant R-515B combines the positive properties of a 77 per cent lower GWP than R- 134a with a classification as safety level A1 ac- cording to EN 378-1,” he said.
“This means that, unlike R-1234ze (A2L), it is considered a non-combustible safety re- frigerant.”
R-515B is an azeotropic mixture, 91.9 per cent R-1234ze and 8.9 per cent R-227ea.
With a GWP value of 293, R515B meets the re-
quirements of the F-Gas Reg- ulation – until at least 2030. “Another important ad-
vantage for companies oper- ating existing machines running on R-134a is that R- 515B is classified as A1, so no additional safety meas- ures need to be taken for the machine room containing the chiller or heat pump,” Keller said.
“With the new refrigerant R-515B, the chiller achieves almost the same refrigera- tion capacity and energy ef- ficiency as with R-1234ze.
“This means that R-515B is suitable for cus- tomers from all industries that require optimal refrigeration capacity and also wish to switch to an eco-friendly and sustainable refrigerant.” ✺
R-515B is now available for QUANTUM chillers.
Circlemiser all round efficiency.
Circlemiser is born from the ultra-efficient technology of Turbomiser, the new series of most efficient air-cooled chillers on the market.
Circlemiser is characterized by innovative technological solutions such as the design and development of particular cylindrical condensers and the use of flooded evaporators connected in series
Thanks to these solutions, Circlemiser ensures an increase in EER *up to 15%, improving the already very high efficiency guaranteed by the Turbomiser technology.
*EER = COP coefficient of performance in accordance with AHRI Standard 551/590 (SI).
