The Tranquility Vertical Stack Hybrid (TRW) Series offers a labor-saving solution where individual, quiet control of the heating and cooling system is important. The compressor-based cooling cycle uses EarthPure® (HFC-410A) refrigerant, to help protect the environment as well as deliver maximum comfort, efficiency, and reliability. The hydronic heating cycle uses loop water for economical, quiet, and dependable heat. When units in a building are both cooling and heating, heat rejected in the loop by units in cooling mode becomes “free” heat for units in heating mode.
