06TSR186 75HP Semi Hermetic Screw Type Compressor for Low Temp Cold Room
75HP semi hermetic screw compressor
,low temperature cold room compressor
,Carlyle semi hermetic compressor
Engineered specifically for low-temperature freezing, blast chillers, and commercial cold storage applications utilizing R22, R404A, and R507 refrigerants, this 75 HP nominal class semi hermetic screw type compressor delivers an impressive volumetric displacement of 186 CFM (312 m3/hr) at 60Hz and 155 CFM (258 m3/hr) at 50Hz. Its patented rotor profile geometry minimizes gas slip, preserving high mass flow and volumetric efficiency at deep-freezing suction pressures.
Equipped with a dynamic slide-valve control mechanism, the compressor provides continuous, stepless capacity regulation from 25% to 100%. Dynamic volume ratio optimization under partial load matches cooling output directly to instantaneous facility thermal demand, optimizing energy efficiency during long freezing cycles.
Featuring a standard 1-3/8 in economizer connection, the unit integrates with liquid subcooling economizer circuits. Utilizing the economizer port substantially boosts total refrigeration capacity and system COP under severe low-temperature operating conditions without requiring proportional energy increases.
Built with high-durability SKF or NSK rolling bearings and a reinforced thrust bearing assembly, the internal mechanism relies on internal pressure differentials for continuous oil circulation, eliminating the need for an external oil pump. An internal check valve stops reverse rotor rotation upon shutdown, while integrated safety valves simplify system maintenance.
Powered by a heavy-duty electric drive rated for 56 kW (60Hz) and 47 kW (50Hz) input power, the compressor supports Star-Delta and Direct-On-Line starting across standard global utility voltages. Embedded NTC thermistors paired with optional electronic modules (Kriwan or Paragon) provide continuous protection against thermal and electrical overload.
- Standard: Terminal box, oil system components, motor protection device, capacity control device, stop valve
- Optional: Paragon control module / Kriwan protection module, oil separator, flanges, economizer, oil cooler, high-temperature expansion valve
