Product Description
Product Overview
  • High-Efficiency Rotor Geometry: Patented asymmetric rotor profile ensures smooth meshing and continuous gas displacement, delivering robust compression performance for heavy-duty screw compressor HVAC applications.
  • Flexible Stepless Capacity Regulation: Provides 4-step capacity control (100%, 75%, 50%, 25%) and continuous stepless modulation to match high-capacity chiller loads precisely in a screw compressor HVAC system.
  • Integrated Multi-Stage Oil Separation: Built-in internal oil separator achieves up to 99.85% separation efficiency, minimizing oil carryover and maintaining optimal heat exchange performance in large screw compressor HVAC units.
  • Advanced Motor Thermal Protection: Equipped with an INT69 SNY protection module and six embedded PTC thermistors for real-time monitoring of motor coils and discharge gas temperatures.

Frequently Asked Questions
Q: What design guidelines should be followed when sizing suction and discharge headers for the SRC-S(W)-553 (SRC-S-553-L4) compressor?

A: Piping must match the 105.5 mm (4-1/8") suction line and 80.0 mm (3-1/8") discharge connection to prevent pressure drops and ensure smooth refrigerant flow.

Q: How does the slide valve control mechanism operate during variable chiller load demands?

A: The hydraulic slide valve shifts via solenoid valves to provide stepped control at 100%, 75%, 50%, and 25%, or continuous stepless modulation across the 100% to 25% range.

Q: What pre-start electrical checks are necessary before energizing the 220 HP motor?

A: Verify that the 275W crankcase heater has been energized to evaporate liquid refrigerant, check phase rotation sequence, and confirm proper wiring of the INT69 SNY protection module.

Q: What routine maintenance practices ensure reliable long-term oil management in this high-capacity unit?

A: Regularly monitor oil level visibility through the sight glass, inspect suction strainer cleanliness, and periodically test lubricant viscosity and acidity.
