Key Features
  • High-Efficiency Rotor Geometry
    Patented rotor profile design ensures smooth meshing and continuous gas displacement, maximizing compression efficiency for heavy-duty commercial refrigeration.
  • Integrated Internal Oil Separator
    Multi-stage oil separation reaches up to 99.85% efficiency, minimizing oil carryover and ensuring high heat transfer performance in system heat exchangers.
  • Flexible Stepless Capacity Regulation
    Features 4-step capacity control (100%, 75%, 50%, 25%) and continuous stepless modulation to match real-time cooling loads efficiently.
  • Advanced Motor Thermal Protection
    Equipped with an INT69 SNY protection module and 6 embedded PTC thermistors for continuous real-time temperature monitoring of motor coils and discharge gas.

Frequently Asked Questions
Q: What technical parameters are needed to correctly select the SRC-S-305 screw type refrigeration compressor for a project?

A: You should provide the required cooling capacity, operating evaporating and condensing temperatures, refrigerant selection, supply power standards, and whether economizer subcooling or liquid injection is required.

Q: What pre-commissioning checks should be completed before starting this compressor?

A: Energize the crankcase electrical heater beforehand to prevent liquid refrigerant accumulation, verify correct three-phase supply sequence, check oil clarity through the sight glass, and inspect suction filter cleanliness.

Q: How does the built-in protection system react to high operating temperatures?

A: The INT69 SNY module processes signals from six internal PTC thermistors placed in motor windings and discharge areas, opening the safety circuit to trip the unit if operating limits are exceeded.
