WaterFurnace’s Envision 30-ton water-source heat pump now offers efficiencies that go beyond ASHRAE 90.1 standards. The unit has a modular, take-apart design that can be moved into a building in two different sections, providing a reduced weight, smaller footprint and improved maneuverability. The Envision includes a variable-frequency drive with an LCD display, two high-efficiency Danfoss scroll compressors and coaxial heat exchangers with copper inner tube and steel outer tubes for maximum heat transfer.
