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. 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. Standard features include foil-backed air handler insulation, MERV11 pleated 2″ filters (standard on residential units) and dehumidification mode – all help to promote IAQ. ClimateMaster’s Tranquility 27 heat pumps are available in sizes 2 tons (7.6 kW) through 6 tons (21.1 kW) with efficiencies up to 31.5 EER and 5.1 COP. Tranquility 27 heat pumps are rated for water loop heat pump, ground loop heat pump and ground water heat pump applications in upflow, downflow, horizontal and split system configurations.For product specifications, visit the company website linked below.
