R452b is an environment-friendly alternative to R410a gas with a GWP value of 675. Other options include partial heat recovery with a desuperheater or full heat recovery, making these chillers a multi-purpose solution for simultaneous, year-round production of chilled and hot water.įor new chillers, Kaltra engineers adapted the new condensers based on low-volume microchannel coils, which reduced the overall refrigerant charge by 25% compared to previous scroll chiller generation, while simultaneously increased heat transfer efficiency. Lightstream Scroll R452b chillers will be available in the capacity range from 200 to 800kW and may be fitted with the highly efficient free cooling system. Following the debut of its water-cooled chillers running on refrigerant R452b this March, Kaltra announces an air-cooled range of chillers with scroll compressors using this low-GWP refrigerant.
