ClimateMaster recently added six ton-units to its Tranquility 27 product line, a series of geothermal and water-source heat pumps that use EarthPure® (HFC-410A) zero ozone depletion refrigerant. 

The Tranquility 27 series has been an industry leader in efficiency and features since its introduction in 2004.  Now that Copeland offers larger capacity unloading scroll compressors, ClimateMaster can add a size 72 to the product line.  Unique Tranquility 27 features such as double-isolated compressor mounting and ECM variable speed fan motor make it one of the quietest units on the market.
