06TSM155 High-Performance 75 HP Refrigeration Screw AC Compressor
Product Advantages
75 HP Capacity Class for Mid-Temperature Refrigeration & HVAC
Engineered for medium-temperature refrigeration and air conditioning applications utilizing R22, R404A, and R507, this 75 HP nominal class screw AC compressor delivers a large volumetric displacement of 155 CFM (260 m³/hr) at 60Hz and 129 CFM (215 m³/hr) at 50Hz. Its patented rotor profile geometry reduces internal gas bypass to ensure steady mass flow under demanding continuous operation.
Precision Stepless Capacity Modulation
Equipped with an advanced slide-valve control mechanism, the compressor provides continuous, stepless capacity regulation from 25% to 100%. Dynamic volume ratio optimization under partial load matches system output to facility thermal load, reducing energy consumption during low-demand cycles.
Factory Economizer Port for Peak Subcooling COP
Featuring a standard 1-3/8 in economizer connection, the unit integrates with liquid subcooling economizer circuits. Utilizing the economizer port increases total system refrigeration capacity and COP without incurring proportional power increases.
Oil-Pump-Free Drive System & Heavy-Duty Bearings
Built with high-durability SKF or NSK rolling bearings and a heavy-duty thrust bearing assembly, the internal mechanism relies on internal differential pressure for lubrication, eliminating the need for an external oil pump. An internal check valve prevents reverse rotor rotation at shutdown, while an external oil filter simplifies system maintenance.
Multi-Grid Electrical Compatibility & Motor Thermal Guard
Powered by a heavy-duty electric drive rated for 56 kW (60Hz) and 47 kW (50Hz) input power, the compressor supports Y-Δ 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 electrical and thermal overload.
Standard & Optional Accessories:
Standard: Terminal box, oil system components, motor protection device, capacity control device, stop valve
