High-Efficiency Rotor Geometry — Patented rotor profile supports smooth engagement and low-vibration operation, delivering high compression performance for commercial and industrial refrigeration.
Flexible Cooling Capacity Regulation — Features 100%, 75%, 50%, and 25% stepped load control along with continuous stepless adjustment to match variable system refrigeration demands.
Integrated Internal Oil Separator — High-efficiency multi-stage internal oil separation reaches up to 99.85%, minimizing oil circulation and protecting system heat exchanger performance.
Advanced Motor Thermal Protection — Equipped with an INT69 SNY control module and 6 embedded PTC thermistors to ensure constant monitoring of motor windings and discharge temperatures.
Q: What information should be submitted for technical selection of the class="lazy" src="/myres/images/load_icon.gif" data-original-S(W)-213 (class="lazy" src="/myres/images/load_icon.gif" data-original-S-213-L4) semi hermetic screw compressor?
A: Provide target cooling capacity, design evaporating and condensing temperatures, refrigerant type, supply voltage/frequency, and whether an economizer or liquid injection loop is required.
Q: What crucial pre-start checks ensure safe commissioning of this unit?
A: Energize the crankcase heater prior to initial startup to clear liquid refrigerant, verify correct phase rotation sequence, and check that oil level and suction filter cleanliness meet startup standards.
Q: How does the built-in INT69 SNY module protect the motor and internal components?
A: The INT69 SNY module processes real-time signals from six internal PTC thermistors embedded in motor windings and the discharge port, opening the control circuit if over-temperature limits are detected.
Q: What basic routine maintenance maintains stable lubrication and system reliability?
A: Regularly inspect oil sight glass clarity, monitor differential pressure across strainers and filters, and check terminal box connection tightness during routine plant service inspections.
