Heat Pump Systems

CITY MULTI VRF Water Source Heat Pumps - Outdoor Units

WY-Series

Overview

W-Series units combine the convenience of water-source systems with VRF technology. These units are easily installed indoors, which means that system performance efficiency is independent of outdoor ambient temperatures.

  • 208/230V, 3-Phase, 60Hz and 460V, 3-Phase, 60Hz options
  • Designed for closed water loops
  • Self-cooling cabinet design
  • Inlet water temperature range: 23-113° F
  • Max. Total Refrigerant Piping Length: 984' (P72,96,120), 1,640' (P144,168,192,216,240,264,288,312,336,360)
  • Connects to CITY MULTI indoor units; controlled via CITY MULTI Controls Network (CMCN)
  • External finish: Acrylic-painted steel
