Product Description
06TSR155 75 HP Screw Type Refrigeration Compressor for Freezing Room
Product Advantages
75 HP Capacity Class for Low-Temperature Freezing
Engineered specifically for low-temperature freezing and commercial cold storage applications utilizing R22, R404A, and R507 refrigerants, this 75 HP nominal class screw type refrigeration 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 minimizes internal gas slip to maintain high mass flow and volumetric efficiency at deep-freezing suction pressures.

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 overall power consumption during duty cycles.

Factory Economizer Port for Enhanced Deep-Freeze COP
Featuring a standard 1-3/8 in economizer connection, the unit integrates with liquid subcooling economizer circuits. Utilizing the economizer port increases total refrigeration capacity and system COP under low-temperature operating conditions 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 upon shutdown, while integrated safety relief valves simplify 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 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 thermal and electrical overload supervision.
