Product Description
Product Description
  • High-Efficiency Rotor Geometry — Patented asymmetric rotor profile ensures smooth, precise meshing and continuous gas displacement, delivering optimized compression performance for heavy-duty commercial cooling applications.
  • Heavy-Duty Bearing Architecture — Precision high-load axial bearings and robust housing construction support low vibration and extended operational service life under continuous full-load demand.
  • Multi-Stage Internal Oil Separation — Integrated internal oil separator achieves up to 99.85% separation efficiency, significantly reducing lubricant carryover to maintain high heat exchanger effectiveness.
  • Flexible Stepless Capacity Regulation — Provides 4-step capacity control (100%, 75%, 50%, 25%) as well as continuous stepless modulation to match fluctuating air conditioning and industrial cooling loads.

FAQ
Q: What information should be submitted when selecting the SRC-S(W)-785 (SRC-S-785-L4) AC screw compressor for system design?

A: You should provide target cooling capacity, design evaporating and condensing temperatures, target refrigerant type, power supply standards, and economizer subcooling requirements.

Q: What crucial pre-start steps ensure proper commissioning of the oil and electrical systems?

A: Energize the 275W crankcase heater prior to initial startup to clear liquid refrigerant, verify correct three-phase rotation sequence, and check that the oil level is clearly visible in the sight glass.

Q: How does the built-in INT69 SNY module safeguard the compressor during operation?

A: The INT69 SNY protection module processes real-time resistance signals from six series-connected PTC thermistors embedded in the motor windings and discharge port, tripping the control relay if thermal limits are exceeded.

Q: What routine maintenance practices help ensure stable long-term lubrication performance?

A: Regularly inspect oil sight glass level and clarity, monitor differential pressure across suction strainers and oil filters, and periodically test lubricant quality for viscosity loss or contamination.
