06NW2146S7EA-A00 Semi Hermetic Screw Type Compressor for Chiller
Semi Hermetic Screw Compressor for Chiller
,Carlyle Semi Hermetic Compressor
,Chiller Screw Type Compressor
Engineered with a high-efficiency patented profile rotor geometry, this semi hermetic screw type compressor minimizes internal clearance gaps to maximize volumetric efficiency. Built-in speed-increasing gears optimize rotor velocity, delivering a steady displacement of 146 CFM tailored for water-cooled chiller applications.
Equipped with a factory 1-3/8 in economizer interface, this 50 HP semi hermetic screw type compressor supports subcooling operation. The economizer connection boosts system refrigeration output while maintaining low power consumption under varying load requirements.
Featuring dual solenoid valve controls, this model supports flexible three-step unloading (100%, 66%, and 33%). This dynamic load-matching capability enables precise temperature regulation and minimizes operational energy costs during partial-load conditions.
Constructed with high-precision SKF or NSK rolling bearings and reinforced thrust bearings, the mechanical assembly reliably handles continuous axial loads. An internal check valve prevents shutdown rotor reversal, while an integrated safety relief valve, oil filter, and suction strainer protect internal mechanisms and suppress operational noise.
Designed for 50Hz and 60Hz universal voltage standards, the 50 HP motor supports Star-Delta conversion and Direct-On-Line (DOL) starting modes. Embedded NTC thermistor sensors offer direct thermal protection across motor windings.
