WATER-COOLED CHILLERS
Featuring a combination of inverter-fed and fixed-speed compressors, the range offers high energy efficiency throughout the entire operating range
Applications: Air conditioning • Process cooling • Refrigeration • Commercial
Powerstream Screw Inverter is a solution best matched to meet the 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.
The entire series is ERP 2021 compliant with 20 unit sizes that cover cooling capacities from 500 to 1800 kW.
POWERSTREAM SCREW INVERTER
This product line enables customers to build future-proof, demand-responsive cooling solutions characterized by high seasonal efficiencies and correspondingly low operating expenses.
For the Powerstream Screw product line, we selected premium components and advanced technologies, ensuring high reliability, top efficiency, and long service life.
We recommend operating Powerstream chillers together with Bora or Mistral series dry coolers. These dry coolers specifically engineered and optimized for use with water-cooled chillers, offer high performance, and enable a close temperature approach.
The Bora series is well-suited for urban locations due to their low sound emission, as well as for high-polluted areas and coastal installation due to the high corrosion resistance of microchannel heat exchangers used in the unit design. For the installations in hot climate zones, we recommend Bora dry coolers with evaporative pads. Evaporative dry coolers lower temperature of the air entering cooling coils, thus enabling lower condenser water temperatures and providing energy savings on compressors of up to 35%. Bora dry coolers feature EC-fans with Modbus control and supplied pre-wired.
Mistral series dry coolers equipped with finned tube heat exchangers with internally grooved copper tubes and are ideal for any kind of industrial and commercial applications. These dry coolers are inherently robust, simple by design and perfect in the specification. Protective coatings make Mistral dry coolers highly corrosion-resistant and improve service life of the system.
