Heat Recovery Systems


R2 - Series


The R2-Series simultaneously cools and heats different zones within a building to provide energy-saving heat-recovery operation through the use of the BC Controller.

  • Supports up to 50 indoor units
  • Available in both 208/230V and 460V up to 30 tons for various applications
  • Cool one zone while heating another
  • Set up zones to maximize simultaneous operation
  • INVERTER-driven compressor for outstanding performance and optimized energy usage
  • Uses a two-pipe system for increased installation savings
  • Maximum pipe length: 2,624 feet
