Kaltra is now offering low-GWP refrigerant R452b across its Easystream-M range of modular water-cooled chillers with scroll compressors - an environment-friendly alternative to R410a gas with a GWP value as low as 675. R452b is a zeotropic HFO/HFC blend classified as a mildly flammable refrigerant (A2L ASHRAE safety class) which delivers an optimal balance of performance, safety, and compatibility to replace R410a and outperforms other R410a alternatives.
The new R452b chillers demonstrate the similar or 2 to 5 percent higher efficiencies than those of R410a and able to operate with a wider range of evaporation temperatures.
The modular design of Easystream-M and new control software allow using multiple chillers virtually as a single system, thus optimizing part load efficiency of the cooling plant.
Headquartered in Germany, Kaltra Innovativtechnik GmbH designs, develops, and manufactures air conditioning and refrigeration equipment and systems. The company offers air-cooled, water-cooled, and free cooling chillers, precision air conditioners, IT cooling systems, including room-, rack- and row-based solutions, and energy management solutions. It also designs and manufactures air-cooled condensers, dry coolers, and cooling units for special applications. Additionally, Kaltra offers microchannel heat exchangers for condenser, evaporator, and water cooling and heating applications, as well as aluminium coils for small cooling applications. All Kaltra products are engineered with the clear objective of improving energy efficiency and reducing total cost of ownership.
