All the benefits of VRV in a water cooled design.

VRV IV W-Series systems are equivalent to 4-pipe chilled water systems, but also offer a viable alternative to Water Source Heat Pump solutions. Each connected indoor unit can provide heating and cooling independently to suit zone requirements making these systems suitable for both open plan, or cellular applications with different operation requirements.

  • VRV with Variable Refrigerant Temperature (VRT) technology Capacity range from 6 to 21 tons
  • 460V / 3ph / 60Hz (RWEYQ_PCYD)

Benefits

N/A

  • Connects to the full suite of advanced Daikin Control Solutions including ITouch Controller and I-Touch Manager for complete system control.
  • BMS flexibility with integration capabilities to Open Protocol Building Management Systems via the Daikin BACnet® and LonWorks® interfaces
  • Flexible piping layout - up to 980 feet of pipe (390 feet max. linear liquid piping length) and 164 feet height difference.
  • Maximum system diversity with up to 130% connectivity of nominal capacity.
  • Flexibility with optimum water flow rates per module of 16 gpm or greater (operable range13.2 ~ 39.5 gpm).
  • The advanced, self-diagnostic, auto-check function will detect a malfunction and immediately display the type and location so it can be resolved quickly and effectively.
