Indoor Split Parallel Unit — Remote Condenser Parallel Compressor System
【Pre-Commissioned, Ready to Run on Delivery】
Pre-Installation Testing: Units undergo simulated layout and commissioning during production for plug-and-play deployment.
【High Protection with Multiple Safety Devices】
Comprehensive Safeguards: Integrated suction/liquid separators, oil separators, and high/low pressure protection for fail-safe reliability.
【Multiple Voltage and Refrigerant Options】
Voltage & Refrigerant Flexibility: Supports 380V-50/60Hz or 220V-50/60Hz and R404A/R449A/R448A/R507A/R452A.
【Intelligent Load Regulation, Uninterrupted Operation】
Intelligent Load Modulation: Multi-compressor parallel design dynamically adjusts active units based on cooling demand. If one compressor fails, others automatically compensate.
