Kaltra - Model 500-1800kW -Powerstream Screw Inverter Chillers
Featuring a combination of inverter-fed and fixed-speed compressors, the range offers high energy efficiency throughout the entire operating range.
Powerstream Screw Inverter is a solution best matched to meet a growing demand for cooling, as well as for cooling plants with varying load. These water-cooled chillers are built with advanced, carefully selected components, ensuring continuous trouble-free operation.
With inverter-driven and fixed-speed screw compressors piped to a single refrigeration circuit and regulated by the advanced control logic, Powerstream Screw Inverter chiller precisely matches the actual cooling load. Smooth capacity modulation enables substantial energy savings and provides precise thermal control. These chillers are particularly suitable for use in variable-flow applications.
The entire series is ERP 2021 compliant with 20 unit sizes that cover cooling capacities from 500 to 1800 kW.
