• ZR190KCE-TFD
• ZR250KCE-TWD-522
• ZR310KCE-TED-522
• ZR380KC-TWD-522

Technology & Use

• Scroll design — fewer moving parts than reciprocating types → higher reliability, low vibration, and lower noise.  
• Suitable for comfort and process cooling (water chillers, rooftops, close-control units).  
• Wide model range: approximately ZR18 (~1.5 HP) up to ZR380 (~30 HP).  

Refrigerants
    •    Models commonly rated for R22, R407C and R134a (some also support R513A).  

Voltage & Phase
    •    Available in single-phase and three-phase configurations.
    •    Common industrial supply voltages: 380–420 V (3 phase, 50 Hz) / 460 V (60 Hz) series codes like TFD or TWD.  

Applications
    •    Commercial HVAC (large buildings, malls, airports)
    •    Industrial process cooling
    •    Refrigeration systems (cold-stores, freezers)
    •    Tandem/trio configurations for larger systems.
