The Envision2 Compact Series commercial geothermal heat pump offers efficiencies and features in a cabinet that is among the industry’s smallest, making the unit ideal for boiler/tower applications and the replacement of aging water source heat pumps, the company claimed. Available in 0.75- to 6-ton capacities, the heat pump design incorporates a number of advanced features, including the Aurora generation of communicating controls. Options include a factory-installed 24-V motorized on-off water valve for variable-frequency drive pumping with automatic internal water flow control; hot gas bypass and reheat; and high-efficiency PSC, five-speed ECM, or variable-speed ECM motors to meet efficiency and comfort needs. All Envision2 Compact units use R-410A and are more than twice as efficient as ASHRAE 90.1 efficiency standards, claimed the manufacturer. Single-speed models operate with a Copeland 5-K Scroll™ or LG rotary compressor, while dual-capacity units use a Copeland UltraTech™ compressor. All Envision2 Compact heat pumps feature coaxial heat exchangers that are oversized and convoluted with a copper inner tube and steel outer tube for maximum heat transfer at normal and low water flow rates, minimizing pressure drop. The heat pump’s cabinet is constructed of heavy-gauge environmentally responsible galvanized steel for maximum corrosion resistance. Interior surfaces are lined with ½-inch-thick, foil-lined acoustic fiber insulation.
