WATER-COOLED CHILLERS
Reliable and versatile water-cooled chillers with screw compressors and dual refrigerant circuit designed to provide maximum thermal efficiency
Applications: Air conditioning • Process cooling • Refrigeration • Commercial
Equipped with the dual refrigerant circuit, Powerstream Screw DC chillers cover cooling capacity from 600kW to 1200kW with modulation in the range of 25-100%. Installed screw compressors feature slider control to achieve a high level of efficiency at loads of 60 to 100 percent.
Whether used in an industrial plant, commercial building, or data center, Powerstream Screw DC water chiller fits your unique requirements. Engineered to deliver maximum performance and combining a set of benefits such as sustainable design and low maintenance cost, Powerstream Screw DC chillers are proven performers with unprecedented energy efficiency and the highest degree of reliability.
POWERSTREAM SCREW DC
The design of this chiller with two independent refrigeration circuits is advantageous for the customers focused on 24/7, reliable cooling service without interruption.
Powerstream Screw DC chillers are equipped with premium quality, high-performance components, making it the most reliable choice for every application, be it high-availability data center, process cooling, or air conditioning
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.
