LATEST SCREW COMPRESSOR TECHNOLOGY WITH CAPACITY CONTROL
Lightstream Screw-V range features compact semi-hermetic screw compressors designed specifically for highly efficient air-cooled chillers and heat pumps for operation with refrigerants R134a, R1234ze, or R513a, and optimized for the ambient temperature profile specified by the Ecodesign Directive for water chillers (European Chiller Energy Efficiency Standard EU 2016/2281 Tier 1, effective from January 2018).
The application limits of the compressors have been substantially extended towards low condensing temperatures as well as to high pressure ratios – without compromises regarding operating reliability.
The compressors feature an integrated oil separation system, economizer technology, and infinite capacity control achieved by changing the control sequence of integrated solenoid valves.
