RTWD heat pump

265-1140 kW

Main features

  • Low-speed, direct-drive semi-hermetic screw compressor featuring only 3 moving parts, suction-gas-cooled motor
  • Near zero GWP (<1) refrigerant R1234ze
  • R134a
  • Trane Adaptive Frequency™ Drive (AFD)
  • Fully modulating load control (15-100%)
  • 4 different levels of efficiency:
    • SE: Standard Efficiency
    • HE: High Efficiency
    • XE: eXtra high Efficiency
    • HSE: High Seasonal Efficiency (With AFD)
  • Control of the leaving condenser water temperature from CH530
  • Maximum condenser temperature 75°C with R1234ze (63°C with R134a)
  • Compact physical footprint - fits through standard single-width door
  • Bolt-together construction for easy unit disassembly
  • Simplified piping - the only piping required is for the evaporator and condenser connections
  • Single power connection - reduced wiring costs
  • Factory-mounted star-delta starter panel

Customer benefits
