The Tranquility® (SB) Compact High-Capacity Series (revision C) raises the bar for water-source heat pump efficiencies, features and application flexibility. Not only does the Tranquility SB exceed ASHRAE 90.1 efficiencies, but it also uses R-454B low Global Warming Potential (GWP) refrigerant, making it an extremely environmentally friendly space conditioning product solution. Tranquility SB is eligible for additional LEED® (Leadership in Energy and Environmental Design) points due to its innovative and environmentally-conscious design.

FEATURES

  • Vertical sizes 072 (6 Tons, 21.1 kW) through 300
    (25 Tons, 87.9 kW)
  • Environmentally-friendly R-454B low-GWP refrigerant
  • Refrigerant Detection System (RDS) (required for all sizes)
  • Vertical configurations with front or back return-air discharge and top, front, or back supply-air discharge. Fan discharge on all models are field convertible. Field conversion uses all existing parts, including panels.
  • Electric power entry points from either side of the front
  • Configurable water connections for left or right handling
  • Dual refrigeration circuits (all sizes)
  • Exceeds ASHRAE 90.1 efficiencies
  • Galvanized-steel cabinet construction
  • Insulated divider and separate compressor/air-handler compartments
  • TXV metering device
  • High efficiency backward inclined EC plenum fans
  • Hot Gas Reheat for superior dehumidification without overcooling the space
  • vFlow modulating water valves for head pressure control and superior water flow control in part load operation
  • DXM2.5 Communicating Controls:
    • Multiple communication pathways for unit access and diagnosis:
      • Cloud-based remote monitoring via Wi-Fi communicating color-touchscreen thermostat
      • Connect directly to the system with a handheld service tool
  • Provides real-time unit operating conditions
  • Reduces startup, commissioning, and service time by providing key system temperatures electronically
  • Captures operating conditions in the event of a safety shutdown

OPTIONS

  • BACnet, Modbus, and Johnson Controls N2 compatibility options
    for Building Management Systems (BMS)
  • Sound-absorbing UltraQuiet package
