Trane Sintesis eXcellent GVAF

Trane has introduced new air-cooled Sintesis eXcellent GVAF and water-cooled XStream eXcellent GVWF chillers with magnetic-bearing compressors optimised for ultra-low GWP R1234ze refrigerant.

The high-speed centrifugal compressor technology allows the units to offer larger capacities, wider operating maps matching the toughest European climate conditions, and increased seasonal efficiencies, all within a smaller size. 

R1234ze has a GWP value of one to exceed current F-Gas legislation requirements and help customers reduce their carbon dioxide emissions and achieve extreme part load and full load efficiencies.

“At Trane we embrace the latest technology innovations to better handle the specific and growing cooling needs our customers are facing,” said Erik van Oossanen, portfolio leader at Trane Europe, Middle East and Africa (EMEA). “The new magnetic-bearing compressor technology optimized for R-1234ze has opened the door for solutions that achieve much higher efficiencies, reliably perform in wider operating maps and do so within a smaller footprint, prioritizing low impact on the environment. Thanks to the smaller size, the new Trane chillers are also ideally suited for replacement of older generation chillers, allowing customers to benefit from higher efficiencies with lower overall total cost of ownership.”

The new air-cooled Sintesis eXcellent GVAF models offer capacities from 450kW to 1600kW with seasonal Energy Efficiency Ratio (SEER) up to 6.5, which makes them suitable for hospitals, office buildings and industrial process applications. Additionally, the new Sintesis eXcellent GVAF features models specifically designed for data centre applications with capacity up to 1900kW.

The water-cooled XStream eXcellent GVWF chillers, above, benefit from the magnetic-bearing technology optimised for R1234ze refrigerant, and now offer increased performance and cost effectiveness. The GVWF XSE range delivers from 380 up to 2.1 MW of capacity with SEER of up to 10 and enlarged operating map of up to 30°C evaporator leaving water temperature, making it ideal for comfort cooling, data centres and industrial process applications. 

To take advantage of low ambient conditions, the new chillers also include optimised free cooling system for more efficient combination offering minimized energy consumption of the system.
