Frequently Asked Questions
Q1: How does the 6-cylinder capacity regulation system benefit parallel rack operations?
A1: The three-step capacity output (100%, 66%, 33%) allows rack controllers to adjust displacement finely without cycling the compressor on and off, preventing suction pressure fluctuations and electrical spikes.
Q2: What piping considerations should be checked during the installation of SP6H4000?
A2: Piping should match the 54 mm (2-1/8") suction and 35 mm (1-3/8") discharge line sizes. The 360° rotatable stop valves simplify connection alignment, but lines must be properly clamped to avoid mechanical stress on the valve flanges.
Q3: What routine maintenance practices help protect internal mechanical parts?
A3: Operators should regularly inspect oil levels through the sight glass, verify operating superheat, and clean or replace the outer-accessible suction filter screen during scheduled system maintenance.
Q4: What is the standard MOQ and production lead time?
A4: In-stock sample orders have no MOQ requirement and can be dispatched in as fast as 3 days. Standard factory production orders are generally completed within 10 to 15 working days.
Q5: How are Coolstart compressors packaged and prepared for export transportation?
A5: Compressors are packed in heavy-duty export wooden cases. Sea freight orders are shipped with holding gas/refrigerant pressure, while air freight shipments are depressurized to comply with international aviation safety regulations.
